It accepts 2 arguments: + +1. `namespace` **Required** This is the namespace of your logger so we know if we need to + enable your logger when a debug flag is used. Generally you use the name of + your library or application as first root namespace. For example if you're + building a parser in a library (example) you would set namespace + `example:parser`. +2. `options` An object with additional configuration for the logger. + following keys are recognized: + - `force` Force the logger to be enabled. + - `colors` Colors are enabled by default for the logs, but you can set this + option to `false` to disable it. + +```js +const debug = require('@dabh/diagnostics')('foo:bar:baz'); +const debug = require('@dabh/diagnostics')('foo:bar:baz', { options }); + +debug('this is a log message %s', 'that will only show up when enabled'); +debug('that is pretty neat', { log: 'more', data: 1337 }); +``` + +Unlike `console.log` statements that add and remove during your development +lifecycle you create meaningful log statements that will give you insight in +the library or application that you're developing. + +The created debugger uses different "adapters" to extract the debug flag +out of the JavaScript environment. To learn more about enabling the debug flag +in your specific environment click on one of the enabled adapters below. + +- **browser**: [localStorage](#localstorage), [hash](#hash) +- **node.js**: [environment variables](#processenv) +- **react-native**: [AsyncStorage](#asyncstorage) + +Please note that the returned logger is fully configured out of the box, you +do not need to set any of the adapters/modifiers your self, they are there +for when you want more advanced control over the process. But if you want to +learn more about that, read the next section. + +### Advanced usage + +There are 2 specific usage patterns for `diagnostic`, library developers who +implement it as part of their modules and applications developers who either +use it in their application or are searching for ways to consume the messages. + +With the simple log interface as discussed in the [introduction](#introduction) +section we make it easy for developers to add it as part of their libraries +and applications, and with powerful [API](#api) we allow infinite customization +by allowing custom adapters, loggers and modifiers to ensure that this library +maintains relevant. These methods not only allow introduction of new loggers, +but allow you think outside the box. For example you can maintain a history +of past log messages, and output those when an uncaught exception happens in +your application so you have additional context + +```js +const diagnostics = require('@dabh/diagnostics'); + +let index = 0; +const limit = 200; +const history = new Array(limit); + +// +// Force all `diagnostic` loggers to be enabled. +// +diagnostics.force = process.env.NODE_ENV === 'prod'; +diagnostics.set(function customLogger(meta, message) { + history[index]= { meta, message, now: Date.now() }; + if (index++ === limit) index = 0; + + // + // We're running a development build, so output. + // + if (meta.dev) console.log.apply(console, message); +}); + +process.on('uncaughtException', async function (err) { + await saveErrorToDisk(err, history); + process.exit(1); +}); +``` + +The small snippet above will maintain a 200 limited FIFO (First In First Out) +queue of all debug messages that can be referenced when your application crashes + +#### Production and development builds + +When you `require` the `@dabh/diagnostics` module you will be given a logger that is +optimized for `development` so it can provide the best developer experience +possible. + +The development logger enables all the [adapters](#adapters) for your +JavaScript environment, adds a logger that outputs the messages to `console.log` +and registers our message modifiers so log messages will be prefixed with the +supplied namespace so you know where the log messages originates from. + +The development logger does not have any adapter, modifier and logger enabled +by default. This ensures that your log messages never accidentally show up in +production. However this does not mean that it's not possible to get debug +messages in production. You can `force` the debugger to be enabled, and +supply a [custom logger](#loggers). + +```js +const diagnostics = require('@dabh/diagnostics'); +const debug = debug('foo:bar', { force: true }); + +// +// Or enable _every_ diagnostic instance: +// +diagnostics.force = true; +``` + +##### WebPack + +WebPack has the concept of [mode](https://webpack.js.org/concepts/mode/#usage)'s +which creates different + +```js +module.exports = { + mode: 'development' // 'production' +} +``` + +When you are building your app using the WebPack CLI you can use the `--mode` +flag: + +``` +webpack --mode=production app.js -o /dist/bundle.js +``` + +##### Node.js + +When you are running your app using `Node.js` you should the `NODE_ENV` +environment variable to `production` to ensure that you libraries that you +import are optimized for production. + +``` +NODE_ENV=production node app.js +``` + +### API + +The returned logger exposes some addition properties that can be used used in +your application or library: + +#### .enabled + +The returned logger will have a `.enabled` property assigned to it. This boolean +can be used to check if the logger was enabled: + +```js +const debug = require('@dabh/diagnostics')('foo:bar'); + +if (debug.enabled) { + // + // Do something special + // +} +``` + +This property is exposed as: + +- Property on the logger. +- Property on the meta/options object. + +#### .namespace + +This is the namespace that you originally provided to the function. + +```js +const debug = require('@dabh/diagnostics')('foo:bar'); + +console.log(debug.namespace); // foo:bar +``` + +This property is exposed as: + +- Property on the logger. +- Property on the meta/options object. + +#### .dev/prod + +There are different builds available of `diagnostics`, when you create a +production build of your application using `NODE_ENV=production` you will be +given an optimized, smaller build of `diagnostics` to reduce your bundle size. +The `dev` and `prod` booleans on the returned logger indicate if you have a +production or development version of the logger. + +```js +const debug = require('@dabh/diagnostics')('foo:bar'); + +if (debug.prod) { + // do stuff +} +``` + +This property is exposed as: + +- Property on the logger. +- Property on the meta/options object. + +#### set + +Sets a new logger as default for **all** `diagnostic` instances. The passed +argument should be a function that write the log messages to where ever you +want. It receives 2 arguments: + +1. `meta` An object with all the options that was provided to the original + logger that wants to write the log message as well as properties of the + debugger such as `prod`, `dev`, `namespace`, `enabled`. See [API](#api) for + all exposed properties. +2. `args` An array of the log messages that needs to be written. + +```js +const debug = require('@dabh/diagnostics')('foo:more:namespaces'); + +debug.use(function logger(meta, args) { + console.log(meta); + console.debug(...args); +}); +``` + +This method is exposed as: + +- Method on the logger. +- Method on the meta/options object. +- Method on `diagnostics` module. + +#### modify + +The modify method allows you add a new message modifier to **all** `diagnostic` +instances. The passed argument should be a function that returns the passed +message after modification. The function receives 2 arguments: + +1. `message`, Array, the log message. +2. `options`, Object, the options that were passed into the logger when it was + initially created. + +```js +const debug = require('@dabh/diagnostics')('example:modifiers'); + +debug.modify(function (message, options) { + return messages; +}); +``` + +This method is exposed as: + +- Method on the logger. +- Method on the meta/options object. +- Method on `diagnostics` module. + +See [modifiers](#modifiers) for more information. + +#### use + +Adds a new `adapter` to **all** `diagnostic` instances. The passed argument +should be a function returns a boolean that indicates if the passed in +`namespace` is allowed to write log messages. + +```js +const diagnostics = require('@dabh/diagnostics'); +const debug = diagnostics('foo:bar'); + +debug.use(function (namespace) { + return namespace === 'foo:bar'; +}); +``` + +This method is exposed as: + +- Method on the logger. +- Method on the meta/options object. +- Method on `diagnostics` module. + +See [adapters](#adapters) for more information. + +### Modifiers + +To be as flexible as possible when it comes to transforming messages we've +come up with the concept of `modifiers` which can enhance the debug messages. +This allows you to introduce functionality or details that you find important +for debug messages, and doesn't require us to add additional bloat to the +`diagnostic` core. + +For example, you want the messages to be prefixed with the date-time of when +the log message occured: + +```js +const diagnostics = require('@dabh/diagnostics'); + +diagnostics.modify(function datetime(args, options) { + args.unshift(new Date()); + return args; +}); +``` + +Now all messages will be prefixed with date that is outputted by `new Date()`. +The following modifiers are shipped with `diagnostics` and are enabled in +**development** mode only: + +- [namespace](#namespace) + +#### namespace + +This modifier is enabled for all debug instances and prefixes the messages +with the name of namespace under which it is logged. The namespace is colored +using the `colorspace` module which groups similar namespaces under the same +colorspace. You can have multiple namespaces for the debuggers where each +namespace should be separated by a `:` + +``` +foo +foo:bar +foo:bar:baz +``` + +For console based output the `namespace-ansi` is used. + +### Adapters + +Adapters allows `diagnostics` to pull the `DEBUG` and `DIAGNOSTICS` environment +variables from different sources. Not every JavaScript environment has a +`process.env` that we can leverage. Adapters allows us to have different +adapters for different environments. It means you can write your own custom +adapter if needed as well. + +The `adapter` function should be passed a function as argument, this function +will receive the `namespace` of a logger as argument and it should return a +boolean that indicates if that logger should be enabled or not. + +```js +const debug = require('@dabh/diagnostics')('example:namespace'); + +debug.adapter(require('@dabh/diagnostics/adapters/localstorage')); +``` + +The modifiers are only enabled for `development`. The following adapters are +available are available: + +#### process.env + +This adapter is enabled for `node.js`. + +Uses the `DEBUG` or `DIAGNOSTICS` (both are recognized) environment variables to +pass in debug flag: + +**UNIX/Linux/Mac** +``` +DEBUG=foo* node index.js +``` + +Using environment variables on Windows is a bit different, and also depends on +toolchain you are using: + +**Windows** +``` +set DEBUG=foo* & node index.js +``` + +**Powershell** +``` +$env:DEBUG='foo*';node index.js +``` + +#### hash + +This adapter is enabled for `browsers`. + +This adapter uses the `window.location.hash` of as source for the environment +variables. It assumes that hash is formatted using the same syntax as query +strings: + +```js +http://example.com/foo/bar#debug=foo* +``` + +It triggers on both the `debug=` and `diagnostics=` names. + +#### localStorage + +This adapter is enabled for `browsers`. + +This adapter uses the `localStorage` of the browser to store the debug flags. +You can set the debug flag your self in your application code, but you can +also open browser WebInspector and enable it through the console. + +```js +localStorage.setItem('debug', 'foo*'); +``` + +It triggers on both the `debug` and `diagnostics` storage items. (Please note +that these keys should be entered in lowercase) + +#### AsyncStorage + +This adapter is enabled for `react-native`. + +This adapter uses the `AsyncStorage` API that is exposed by the `react-native` +library to store and read the `debug` or `diagnostics` storage items. + +```js +import { AsyncStorage } from 'react-native'; + +AsyncStorage.setItem('debug', 'foo*'); +``` + +Unlike other adapters, this is the only adapter that is `async` so that means +that we're not able to instantly determine if a created logger should be +enabled or disabled. So when a logger is created in `react-native` we initially +assume it's disabled, any message that send during period will be queued +internally. + +Once we've received the data from the `AsyncStorage` API we will determine +if the logger should be enabled, flush the queued messages if needed and set +all `enabled` properties accordingly on the returned logger. + +### Loggers + +By default it will log all messages to `console.log` in when the logger is +enabled using the debug flag that is set using one of the adapters. + +## License + +[MIT](LICENSE) diff --git a/nodejs/node_modules/@dabh/diagnostics/adapters/hash.js b/nodejs/node_modules/@dabh/diagnostics/adapters/hash.js new file mode 100644 index 00000000..a41aae5c --- /dev/null +++ b/nodejs/node_modules/@dabh/diagnostics/adapters/hash.js @@ -0,0 +1,11 @@ +var adapter = require('./');

+ +## Background + +This module provides a simple base prototype for a key-value store. It has a public API for consumers and a private API for implementors. To implement a `abstract-leveldown` compliant store, extend its prototype and override the private underscore versions of the methods. For example, to implement `put()`, override `_put()` on your prototype. + +Where possible, the default private methods have sensible _noop_ defaults that essentially do nothing. For example, `_open(callback)` will invoke `callback` on a next tick. Other methods like `_clear(..)` have functional defaults. Each method listed below documents whether implementing it is mandatory. + +The private methods are always provided with consistent arguments, regardless of what is passed in through the public API. All public methods provide argument checking: if a consumer calls `open()` without a callback argument they'll get an `Error('open() requires a callback argument')`. + +Where optional arguments are involved, private methods receive sensible defaults: a `get(key, callback)` call translates to `_get(key, options, callback)` where the `options` argument is an empty object. These arguments are documented below. + +**If you are upgrading:** please see [UPGRADING.md](UPGRADING.md). + +## Example + +Let's implement a simplistic in-memory [`leveldown`][leveldown] replacement: + +```js +var AbstractLevelDOWN = require('abstract-leveldown').AbstractLevelDOWN +var util = require('util') + +// Constructor +function FakeLevelDOWN () { + AbstractLevelDOWN.call(this) +} + +// Our new prototype inherits from AbstractLevelDOWN +util.inherits(FakeLevelDOWN, AbstractLevelDOWN) + +FakeLevelDOWN.prototype._open = function (options, callback) { + // Initialize a memory storage object + this._store = {} + + // Use nextTick to be a nice async citizen + process.nextTick(callback) +} + +FakeLevelDOWN.prototype._serializeKey = function (key) { + // As an example, prefix all input keys with an exclamation mark. + // Below methods will receive serialized keys in their arguments. + return '!' + key +} + +FakeLevelDOWN.prototype._put = function (key, value, options, callback) { + this._store[key] = value + process.nextTick(callback) +} + +FakeLevelDOWN.prototype._get = function (key, options, callback) { + var value = this._store[key] + + if (value === undefined) { + // 'NotFound' error, consistent with LevelDOWN API + return process.nextTick(callback, new Error('NotFound')) + } + + process.nextTick(callback, null, value) +} + +FakeLevelDOWN.prototype._del = function (key, options, callback) { + delete this._store[key] + process.nextTick(callback) +} +``` + +Now we can use our implementation with `levelup`: + +```js +var levelup = require('levelup') + +var db = levelup(new FakeLevelDOWN()) + +db.put('foo', 'bar', function (err) { + if (err) throw err + + db.get('foo', function (err, value) { + if (err) throw err + + console.log(value) // 'bar' + }) +}) +``` + +See [`memdown`](https://github.com/Level/memdown/) if you are looking for a complete in-memory replacement for `leveldown`. + +## Browser Support + +[![Sauce Test Status](https://saucelabs.com/browser-matrix/abstract-leveldown.svg)](https://saucelabs.com/u/abstract-leveldown) + +## Public API For Consumers + +### `db = constructor(..)` + +Constructors typically take a `location` argument pointing to a location on disk where the data will be stored. Since not all implementations are disk-based and some are non-persistent, implementors are free to take zero or more arguments in their constructor. + +### `db.status` + +A read-only property. An `abstract-leveldown` compliant store can be in one of the following states: + +- `'new'` - newly created, not opened or closed +- `'opening'` - waiting for the store to be opened +- `'open'` - successfully opened the store, available for use +- `'closing'` - waiting for the store to be closed +- `'closed'` - store has been successfully closed, should not be used. + +### `db.supports` + +A read-only [manifest](https://github.com/Level/supports). Might be used like so: + +```js +if (!db.supports.permanence) { + throw new Error('Persistent storage is required') +} + +if (db.supports.bufferKeys && db.supports.promises) { + await db.put(Buffer.from('key'), 'value') +} +``` + +### `db.open([options, ]callback)` + +Open the store. The `callback` function will be called with no arguments when the store has been successfully opened, or with a single error argument if the open operation failed for any reason. + +The optional `options` argument may contain: + +- `createIfMissing` _(boolean, default: `true`)_: If `true` and the store doesn't exist it will be created. If `false` and the store doesn't exist, `callback` will receive an error. +- `errorIfExists` _(boolean, default: `false`)_: If `true` and the store exists, `callback` will receive an error. + +Not all implementations support the above options. + +### `db.close(callback)` + +Close the store. The `callback` function will be called with no arguments if the operation is successful or with a single `error` argument if closing failed for any reason. + +### `db.get(key[, options], callback)` + +Get a value from the store by `key`. The optional `options` object may contain: + +- `asBuffer` _(boolean, default: `true`)_: Whether to return the `value` as a Buffer. If `false`, the returned type depends on the implementation. + +The `callback` function will be called with an `Error` if the operation failed for any reason. If successful the first argument will be `null` and the second argument will be the value. + +### `db.put(key, value[, options], callback)` + +Store a new entry or overwrite an existing entry. There are no `options` by default but implementations may add theirs. The `callback` function will be called with no arguments if the operation is successful or with an `Error` if putting failed for any reason. + +### `db.del(key[, options], callback)` + +Delete an entry. There are no `options` by default but implementations may add theirs. The `callback` function will be called with no arguments if the operation is successful or with an `Error` if deletion failed for any reason. + +### `db.batch(operations[, options], callback)` + +Perform multiple _put_ and/or _del_ operations in bulk. The `operations` argument must be an `Array` containing a list of operations to be executed sequentially, although as a whole they are performed as an atomic operation. + +Each operation is contained in an object having the following properties: `type`, `key`, `value`, where the `type` is either `'put'` or `'del'`. In the case of `'del'` the `value` property is ignored. + +There are no `options` by default but implementations may add theirs. The `callback` function will be called with no arguments if the batch is successful or with an `Error` if the batch failed for any reason. + +### `db.batch()` + +Returns a [`chainedBatch`](#chainedbatch). + +### `db.iterator([options])` + +Returns an [`iterator`](#iterator). Accepts the following range options: + +- `gt` (greater than), `gte` (greater than or equal) define the lower bound of the range to be iterated. Only entries where the key is greater than (or equal to) this option will be included in the range. When `reverse=true` the order will be reversed, but the entries iterated will be the same. +- `lt` (less than), `lte` (less than or equal) define the higher bound of the range to be iterated. Only entries where the key is less than (or equal to) this option will be included in the range. When `reverse=true` the order will be reversed, but the entries iterated will be the same. +- `reverse` _(boolean, default: `false`)_: iterate entries in reverse order. Beware that a reverse seek can be slower than a forward seek. +- `limit` _(number, default: `-1`)_: limit the number of entries collected by this iterator. This number represents a _maximum_ number of entries and may not be reached if you get to the end of the range first. A value of `-1` means there is no limit. When `reverse=true` the entries with the highest keys will be returned instead of the lowest keys. + +Legacy options: + +- `start`: instead use `gte` +- `end`: instead use `lte`. + +**Note** Zero-length strings, buffers and arrays as well as `null` and `undefined` are invalid as keys, yet valid as range options. These types are significant in encodings like [`bytewise`](https://github.com/deanlandolt/bytewise) and [`charwise`](https://github.com/dominictarr/charwise) as well as some underlying stores like IndexedDB. Consumers of an implementation should assume that `{ gt: undefined }` is _not_ the same as `{}`. An implementation can choose to: + +- [_Serialize_](#db_serializekeykey) or [_encode_][encoding-down] these types to make them meaningful +- Have no defined behavior (moving the concern to a higher level) +- Delegate to an underlying store (moving the concern to a lower level). + +If you are an implementor, a final note: the [abstract test suite](#test-suite) does not test these types. Whether they are supported or how they sort is up to you; add custom tests accordingly. + +In addition to range options, `iterator()` takes the following options: + +- `keys` _(boolean, default: `true`)_: whether to return the key of each entry. If set to `false`, calls to `iterator.next(callback)` will yield keys with a value of `undefined`. +- `values` _(boolean, default: `true`)_: whether to return the value of each entry. If set to `false`, calls to `iterator.next(callback)` will yield values with a value of `undefined`. +- `keyAsBuffer` _(boolean, default: `true`)_: Whether to return the key of each entry as a Buffer. If `false`, the returned type depends on the implementation. +- `valueAsBuffer` _(boolean, default: `true`)_: Whether to return the value of each entry as a Buffer. + +Lastly, an implementation is free to add its own options. + +### `db.clear([options, ]callback)` + +**This method is experimental. Not all implementations support it yet.** + +Delete all entries or a range. Not guaranteed to be atomic. Accepts the following range options (with the same rules as on iterators): + +- `gt` (greater than), `gte` (greater than or equal) define the lower bound of the range to be deleted. Only entries where the key is greater than (or equal to) this option will be included in the range. When `reverse=true` the order will be reversed, but the entries deleted will be the same. +- `lt` (less than), `lte` (less than or equal) define the higher bound of the range to be deleted. Only entries where the key is less than (or equal to) this option will be included in the range. When `reverse=true` the order will be reversed, but the entries deleted will be the same. +- `reverse` _(boolean, default: `false`)_: delete entries in reverse order. Only effective in combination with `limit`, to remove the last N records. +- `limit` _(number, default: `-1`)_: limit the number of entries to be deleted. This number represents a _maximum_ number of entries and may not be reached if you get to the end of the range first. A value of `-1` means there is no limit. When `reverse=true` the entries with the highest keys will be deleted instead of the lowest keys. + +If no options are provided, all entries will be deleted. The `callback` function will be called with no arguments if the operation was successful or with an `Error` if it failed for any reason. + +### `chainedBatch` + +#### `chainedBatch.put(key, value)` + +Queue a `put` operation on this batch. This may throw if `key` or `value` is invalid. + +#### `chainedBatch.del(key)` + +Queue a `del` operation on this batch. This may throw if `key` is invalid. + +#### `chainedBatch.clear()` + +Clear all queued operations on this batch. + +#### `chainedBatch.write([options, ]callback)` + +Commit the queued operations for this batch. All operations will be written atomically, that is, they will either all succeed or fail with no partial commits. + +There are no `options` by default but implementations may add theirs. The `callback` function will be called with no arguments if the batch is successful or with an `Error` if the batch failed for any reason. + +After `write` has been called, no further operations are allowed. + +#### `chainedBatch.db` + +A reference to the `db` that created this chained batch. + +### `iterator` + +An iterator allows you to _iterate_ the entire store or a range. It operates on a snapshot of the store, created at the time `db.iterator()` was called. This means reads on the iterator are unaffected by simultaneous writes. Most but not all implementations can offer this guarantee. + +An iterator keeps track of when a `next()` is in progress and when an `end()` has been called so it doesn't allow concurrent `next()` calls, it does allow `end()` while a `next()` is in progress and it doesn't allow either `next()` or `end()` after `end()` has been called. + +#### `iterator.next(callback)` + +Advance the iterator and yield the entry at that key. If an error occurs, the `callback` function will be called with an `Error`. Otherwise, the `callback` receives `null`, a `key` and a `value`. The type of `key` and `value` depends on the options passed to `db.iterator()`. + +If the iterator has reached its end, both `key` and `value` will be `undefined`. This happens in the following situations: + +- The end of the store has been reached +- The end of the range has been reached +- The last `iterator.seek()` was out of range. + +**Note:** Don't forget to call `iterator.end()`, even if you received an error. + +#### `iterator.seek(target)` + +Seek the iterator to a given key or the closest key. Subsequent calls to `iterator.next()` will yield entries with keys equal to or larger than `target`, or equal to or smaller than `target` if the `reverse` option passed to `db.iterator()` was true. + +If range options like `gt` were passed to `db.iterator()` and `target` does not fall within that range, the iterator will reach its end. + +**Note:** At the time of writing, [`leveldown`][leveldown] is the only known implementation to support `seek()`. In other implementations, it is a noop. + +#### `iterator.end(callback)` + +End iteration and free up underlying resources. The `callback` function will be called with no arguments on success or with an `Error` if ending failed for any reason. + +#### `iterator.db` + +A reference to the `db` that created this iterator. + +### Type Support + +The following applies to any method above that takes a `key` argument or option: all implementations _must_ support a `key` of type String and _should_ support a `key` of type Buffer. A `key` may not be `null`, `undefined`, a zero-length Buffer, zero-length string or zero-length array. + +The following applies to any method above that takes a `value` argument or option: all implementations _must_ support a `value` of type String or Buffer. A `value` may not be `null` or `undefined` due to preexisting significance in streams and iterators. + +Support of other key and value types depends on the implementation as well as its underlying storage. See also [`db._serializeKey`](#db_serializekeykey) and [`db._serializeValue`](#db_serializevaluevalue). + +## Private API For Implementors + +Each of these methods will receive exactly the number and order of arguments described. Optional arguments will receive sensible defaults. All callbacks are error-first and must be asynchronous. + +If an operation within your implementation is synchronous, be sure to invoke the callback on a next tick using `process.nextTick` or some other means of microtask scheduling. For convenience, the prototypes of `AbstractLevelDOWN`, `AbstractIterator` and `AbstractChainedBatch` include a `_nextTick` method that is compatible with node and browsers. + +### `db = AbstractLevelDOWN([manifest])` + +The constructor. Sets the `.status` to `'new'`. Optionally takes a [manifest](https://github.com/Level/supports) object which `abstract-leveldown` will enrich: + +```js +AbstractLevelDOWN.call(this, { + bufferKeys: true, + snapshots: true, + // .. +}) +``` + +### `db._open(options, callback)` + +Open the store. The `options` object will always have the following properties: `createIfMissing`, `errorIfExists`. If opening failed, call the `callback` function with an `Error`. Otherwise call `callback` without any arguments. + +The default `_open()` is a sensible noop and invokes `callback` on a next tick. + +### `db._close(callback)` + +Close the store. If closing failed, call the `callback` function with an `Error`. Otherwise call `callback` without any arguments. + +The default `_close()` is a sensible noop and invokes `callback` on a next tick. + +### `db._serializeKey(key)` + +Convert a `key` to a type supported by the underlying storage. All methods below that take a `key` argument or option - including `db._iterator()` with its range options and `iterator._seek()` with its `target` argument - will receive serialized keys. For example, if `_serializeKey` is implemented as: + +```js +FakeLevelDOWN.prototype._serializeKey = function (key) { + return Buffer.isBuffer(key) ? key : String(key) +} +``` + +Then `db.get(2, callback)` translates into `db._get('2', options, callback)`. Similarly, `db.iterator({ gt: 2 })` translates into `db._iterator({ gt: '2', ... })` and `iterator.seek(2)` translates into `iterator._seek('2')`. + +If the underlying storage supports any JavaScript type or if your implementation wraps another implementation, it is recommended to make `_serializeKey` an identity function (returning the key as-is). Serialization is irreversible, unlike _encoding_ as performed by implementations like [`encoding-down`][encoding-down]. This also applies to `_serializeValue`. + +The default `_serializeKey()` is an identity function. + +### `db._serializeValue(value)` + +Convert a `value` to a type supported by the underlying storage. All methods below that take a `value` argument or option will receive serialized values. For example, if `_serializeValue` is implemented as: + +```js +FakeLevelDOWN.prototype._serializeValue = function (value) { + return Buffer.isBuffer(value) ? value : String(value) +} +``` + +Then `db.put(key, 2, callback)` translates into `db._put(key, '2', options, callback)`. + +The default `_serializeValue()` is an identity function. + +### `db._get(key, options, callback)` + +Get a value by `key`. The `options` object will always have the following properties: `asBuffer`. If the key does not exist, call the `callback` function with a `new Error('NotFound')`. Otherwise call `callback` with `null` as the first argument and the value as the second. + +The default `_get()` invokes `callback` on a next tick with a `NotFound` error. It must be overridden. + +### `db._put(key, value, options, callback)` + +Store a new entry or overwrite an existing entry. There are no default options but `options` will always be an object. If putting failed, call the `callback` function with an `Error`. Otherwise call `callback` without any arguments. + +The default `_put()` invokes `callback` on a next tick. It must be overridden. + +### `db._del(key, options, callback)` + +Delete an entry. There are no default options but `options` will always be an object. If deletion failed, call the `callback` function with an `Error`. Otherwise call `callback` without any arguments. + +The default `_del()` invokes `callback` on a next tick. It must be overridden. + +### `db._batch(operations, options, callback)` + +Perform multiple _put_ and/or _del_ operations in bulk. The `operations` argument is always an `Array` containing a list of operations to be executed sequentially, although as a whole they should be performed as an atomic operation. Each operation is guaranteed to have at least `type` and `key` properties. There are no default options but `options` will always be an object. If the batch failed, call the `callback` function with an `Error`. Otherwise call `callback` without any arguments. + +The default `_batch()` invokes `callback` on a next tick. It must be overridden. + +### `db._chainedBatch()` + +The default `_chainedBatch()` returns a functional `AbstractChainedBatch` instance that uses `db._batch(array, options, callback)` under the hood. The prototype is available on the main exports for you to extend. If you want to implement chainable batch operations in a different manner then you should extend `AbstractChainedBatch` and return an instance of this prototype in the `_chainedBatch()` method: + +```js +var AbstractChainedBatch = require('abstract-leveldown').AbstractChainedBatch +var inherits = require('util').inherits + +function ChainedBatch (db) { + AbstractChainedBatch.call(this, db) +} + +inherits(ChainedBatch, AbstractChainedBatch) + +FakeLevelDOWN.prototype._chainedBatch = function () { + return new ChainedBatch(this) +} +``` + +### `db._iterator(options)` + +The default `_iterator()` returns a noop `AbstractIterator` instance. It must be overridden, by extending `AbstractIterator` (available on the main module exports) and returning an instance of this prototype in the `_iterator(options)` method. + +The `options` object will always have the following properties: `reverse`, `keys`, `values`, `limit`, `keyAsBuffer` and `valueAsBuffer`. + +### `db._clear(options, callback)` + +**This method is experimental and optional for the time being. To enable its tests, set the [`clear` option of the test suite](#excluding-tests) to `true`.** + +Delete all entries or a range. Does not have to be atomic. It is recommended (and possibly mandatory in the future) to operate on a snapshot so that writes scheduled after a call to `clear()` will not be affected. + +The default `_clear()` uses `_iterator()` and `_del()` to provide a reasonable fallback, but requires binary key support. It is _recommended_ to implement `_clear()` with more performant primitives than `_iterator()` and `_del()` if the underlying storage has such primitives. Implementations that don't support binary keys _must_ implement their own `_clear()`. + +Implementations that wrap another `db` can typically forward the `_clear()` call to that `db`, having transformed range options if necessary. + +The `options` object will always have the following properties: `reverse` and `limit`. + +### `iterator = AbstractIterator(db)` + +The first argument to this constructor must be an instance of your `AbstractLevelDOWN` implementation. The constructor will set `iterator.db` which is used to access `db._serialize*` and ensures that `db` will not be garbage collected in case there are no other references to it. + +#### `iterator._next(callback)` + +Advance the iterator and yield the entry at that key. If nexting failed, call the `callback` function with an `Error`. Otherwise, call `callback` with `null`, a `key` and a `value`. + +The default `_next()` invokes `callback` on a next tick. It must be overridden. + +#### `iterator._seek(target)` + +Seek the iterator to a given key or the closest key. This method is optional. + +#### `iterator._end(callback)` + +Free up underlying resources. This method is guaranteed to only be called once. If ending failed, call the `callback` function with an `Error`. Otherwise call `callback` without any arguments. + +The default `_end()` invokes `callback` on a next tick. Overriding is optional. + +### `chainedBatch = AbstractChainedBatch(db)` + +The first argument to this constructor must be an instance of your `AbstractLevelDOWN` implementation. The constructor will set `chainedBatch.db` which is used to access `db._serialize*` and ensures that `db` will not be garbage collected in case there are no other references to it. + +#### `chainedBatch._put(key, value)` + +Queue a `put` operation on this batch. + +#### `chainedBatch._del(key)` + +Queue a `del` operation on this batch. + +#### `chainedBatch._clear()` + +Clear all queued operations on this batch. + +#### `chainedBatch._write(options, callback)` + +The default `_write` method uses `db._batch`. If the `_write` method is overridden it must atomically commit the queued operations. There are no default options but `options` will always be an object. If committing fails, call the `callback` function with an `Error`. Otherwise call `callback` without any arguments. + +## Test Suite + +To prove that your implementation is `abstract-leveldown` compliant, include the abstract test suite in your `test.js` (or similar): + +```js +const test = require('tape') +const suite = require('abstract-leveldown/test') +const YourDOWN = require('.') + +suite({ + test: test, + factory: function () { + return new YourDOWN() + } +}) +``` + +This is the most minimal setup. The `test` option _must_ be a function that is API-compatible with `tape`. The `factory` option _must_ be a function that returns a unique and isolated database instance. The factory will be called many times by the test suite. + +If your implementation is disk-based we recommend using [`tempy`](https://github.com/sindresorhus/tempy) (or similar) to create unique temporary directories. Your setup could look something like: + +```js +const test = require('tape') +const tempy = require('tempy') +const suite = require('abstract-leveldown/test') +const YourDOWN = require('.') + +suite({ + test: test, + factory: function () { + return new YourDOWN(tempy.directory()) + } +}) +``` + +### Excluding tests + +As not every implementation can be fully compliant due to limitations of its underlying storage, some tests may be skipped. For example, to skip snapshot tests: + +```js +suite({ + // .. + snapshots: false +}) +``` + +This also serves as a signal to users of your implementation. The following options are available: + +- `bufferKeys`: set to `false` if binary keys are not supported by the underlying storage +- `seek`: set to `false` if your `iterator` does not implement `_seek` +- `clear`: defaults to `false` until a next major release. Set to `true` if your implementation either implements `_clear()` itself or is suitable to use the default implementation of `_clear()` (which requires binary key support). +- `snapshots`: set to `false` if any of the following is true: + - Reads don't operate on a [snapshot](#iterator) + - Snapshots are created asynchronously +- `createIfMissing` and `errorIfExists`: set to `false` if `db._open()` does not support these options. + +This metadata will be moved to manifests (`db.supports`) in the future. + +### Setup and teardown + +To perform (a)synchronous work before or after each test, you may define `setUp` and `tearDown` functions: + +```js +suite({ + // .. + setUp: function (t) { + t.end() + }, + tearDown: function (t) { + t.end() + } +}) +``` + +### Reusing `testCommon` + +The input to the test suite is a `testCommon` object. Should you need to reuse `testCommon` for your own (additional) tests, use the included utility to create a `testCommon` with defaults: + +```js +const test = require('tape') +const suite = require('abstract-leveldown/test') +const YourDOWN = require('.') + +const testCommon = suite.common({ + test: test, + factory: function () { + return new YourDOWN() + } +}) + +suite(testCommon) +``` + +The `testCommon` object will have all the properties describe above: `test`, `factory`, `setUp`, `tearDown` and the skip options. You might use it like so: + +```js +test('setUp', testCommon.setUp) + +test('custom test', function (t) { + var db = testCommon.factory() + // .. +}) + +test('another custom test', function (t) { + var db = testCommon.factory() + // .. +}) + +test('tearDown', testCommon.tearDown) +``` + +## Spread The Word + +If you'd like to share your awesome implementation with the world, here's what you might want to do: + +- Add an awesome badge to your `README`: `![level badge](https://leveljs.org/img/badge.svg)` +- Publish your awesome module to [npm](https://npmjs.org) +- Send a Pull Request to [Level/awesome](https://github.com/Level/awesome) to advertise your work! + +## Install + +With [npm](https://npmjs.org) do: + +``` +npm install abstract-leveldown +``` + +## Contributing + +[`Level/abstract-leveldown`](https://github.com/Level/abstract-leveldown) is an **OPEN Open Source Project**.

+ +## v6 + +This release brings a major refactoring of the test suite, decouples `abstract-leveldown` from disk-based implementations and solves long-standing issues around serialization and type support. Because the changes are substantial, this guide has two sections: + +1. **Changes to public API** - for consumers of any implementation. +2. **Changes to private API** - intended for implementors. + +### Changes to public API + +#### Nullish values are rejected + +In addition to rejecting `null` and `undefined` as _keys_, `abstract-leveldown` now also rejects these types as _values_, due to preexisting significance in streams and iterators. + +Before this, the behavior of these types depended on a large number of factors: `_serializeValue` and type support of the underlying storage, whether `get()`, `iterator()` or a stream was used to retrieve values, the `keys` and `asBuffer` options of `iterator()` and finally, which encoding was selected. + +#### Range options are serialized + +Previously, range options like `lt` were passed through as-is, unlike keys. + +#### The rules for range options have been relaxed + +Because `null`, `undefined`, zero-length strings and zero-length buffers are significant types in encodings like `bytewise` and `charwise`, they became valid as range options. In fact, any type is now valid. This means `db.iterator({ gt: undefined })` is not the same as `db.iterator({})`. + +Furthermore, `abstract-leveldown` makes no assumptions about the meaning of these types. Range tests that assumed `null` meant "not defined" have been removed. + +#### Zero-length array keys are rejected + +Though this was already the case because `_checkKey` stringified its input before checking the length, that behavior has been replaced with an explicit `Array.isArray()` check and a new error message. + +#### No longer assumes support of boolean and `NaN` keys + +A test that asserted boolean and `NaN` keys were valid has been removed. + +#### Browser support + +IE10 has been dropped. + +### Changes to private API + +#### `location` was removed + +`AbstractLevelDOWN` is no longer associated with a `location`. It's up to the implementation to handle it if it's required. + +If your implementation has a `location` and you previously did: + +```js +function YourDOWN (location) { + AbstractLevelDOWN.call(this, location) +} +``` + +You must now do: + +```js +function YourDOWN (location) { + this.location = location + AbstractLevelDOWN.call(this) +} +``` + +Be sure to include appropriate type checks. If you relied on the default `AbstractLevelDOWN` behavior that would be: + +```js +if (typeof location !== 'string') { + throw new Error('constructor requires a location string argument') +} +``` + +#### Abstract test suite has moved to a single entry point + +Instead of including test files individually, you can and should include the test suite with one `require()` statement. If you previously did: + +```js +const test = require('tape') +const testCommon = require('abstract-leveldown/testCommon') +const YourDOWN = require('.') + +require('abstract-leveldown/abstract/get-test').all(YourDOWN, test, testCommon) +require('abstract-leveldown/abstract/put-test').all(YourDOWN, test, testCommon) + +// etc +``` + +You must now do: + +```js +const test = require('tape') +const suite = require('abstract-leveldown/test') +const YourDOWN = require('.') + +suite({ + test: test, + factory: function () { + return new YourDOWN() + } +}) +``` + +The input to the test suite is a new form of `testCommon`. Should you need to reuse `testCommon` for your own (additional) tests, use the included utility to create a `testCommon` with defaults: + +```js +const test = require('tape') +const suite = require('abstract-leveldown/test') +const YourDOWN = require('.') + +const testCommon = suite.common({ + test: test, + factory: function () { + return new YourDOWN() + } +}) + +suite(testCommon) +``` + +As part of removing `location`, the abstract tests no longer use `testCommon.location()`. Instead an implementation _must_ implement `factory()` which _must_ return a unique and isolated database instance. This allows implementations to pass options to their constructor. + +The `testCommon.cleanup` method has been removed. Because `factory()` returns a unique database instance, cleanup should no longer be necessary. The `testCommon.lastLocation` method has also been removed as there is no remaining use of it in abstract tests. + +Previously, implementations using the default `testCommon` had to include `rimraf` in their `devDependencies` and browser-based implementations had to exclude `rimraf` from browserify builds. This is no longer the case. + +If your implementation is disk-based we recommend using [`tempy`](https://github.com/sindresorhus/tempy) (or similar) to create unique temporary directories. Together with `factory()` your setup could now look something like: + +```js +const test = require('tape') +const tempy = require('tempy') +const suite = require('abstract-leveldown/test') +const YourDOWN = require('.') + +suite({ + test: test, + factory: function () { + return new YourDOWN(tempy.directory()) + } +}) +``` + +#### The `collectEntries` utility has moved + +The `testCommon.collectEntries` method has moved to the npm package `level-concat-iterator`. If your (additional) tests depend on `collectEntries` and you previously did: + +```js +testCommon.collectEntries(iterator, function (err, entries) {}) +``` + +You must now do: + +```js +const concat = require('level-concat-iterator') +concat(iterator, function (err, entries) {}) +``` + +#### Setup and teardown became noops + +Because cleanup is no longer necessary, the `testCommon.setUp` and `testCommon.tearDown` methods are now noops by default. If you do need to perform (a)synchronous work before or after each test, `setUp` and `tearDown` can be overridden: + +```js +suite({ + // .. + setUp: function (t) { + t.end() + }, + tearDown: function (t) { + t.end() + } +}) +``` + +#### Optional tests have been separated + +If your implementation does not support snapshots or other optional features, the relevant tests may be skipped. For example: + +```js +suite({ + // .. + snapshots: false +}) +``` + +Please see the [README](README.md) for a list of options. Note that some of these have replaced `process.browser` checks. + +#### Iterator must have a `db` reference + +The `db` argument of the `AbstractIterator` constructor became mandatory, as well as a public `db` property on the instance. Its existence is not new; the test suite now asserts that your implementation also has it. + +#### Seeking became part of official API + +If your implementation previously defined the public `iterator.seek(target)`, it must now define the private `iterator._seek(target)`. The new public API is equal to the reference implementation of `leveldown` except for two differences: + +- The `target` argument is not type checked, this is up to the implementation. +- The `target` argument is passed through `db._serializeKey`. + +Please see the [README](README.md) for details. + +#### Chained batch has been refactored + +- The default `_clear` method is no longer a noop; instead it clears the operations queued by `_put` and/or `_del` +- The `_write` method now takes an `options` object as its first argument +- The `db` argument of the `AbstractChainedBatch` constructor became mandatory, as well as a public `db` property on the instance, which was previously named `_db`. + +#### Default `_serializeKey` and `_serializeValue` became identity functions + +They return whatever is given. Previously they were opinionated and mostly geared towards string- and Buffer-based storages. Implementations that didn't already define their own serialization should now do so, according to the types that they support. Please refer to the [README](README.md) for recommended behavior. + +## v5 + +Dropped support for node 4. No other breaking changes. + +## v4 + +#### default `testCommon` parameter + +The `testCommon` parameter will now default to `abstract-leveldown/testCommon.js`. You can omit this parameter, unless your implementation needs a custom version. + +If your code today looks something like: + +```js +const test = require('tape') +const testCommon = require('abstract-leveldown/testCommon') +const leveldown = require('./your-leveldown') +const abstract = require('abstract-leveldown/abstract/get-test') + +abstract.all(leveldown, test, testCommon) +``` + +You can simplify it to: + +```js +const test = require('tape') +const leveldown = require('./your-leveldown') +const abstract = require('abstract-leveldown/abstract/get-test') + +abstract.all(leveldown, test) +``` + +#### `testBuffer` parameter removed + +The `abstract/put-get-del-test.js` previously took a custom `testBuffer` parameter. After an [analysis](https://github.com/Level/abstract-leveldown/pull/175#issuecomment-353867144) of various implementations we came to the conclusion that the parameter has no use. + +If your implementation is using this abstract test, change from: + +```js +const test = require('tape') +const testCommon = require('abstract-leveldown/testCommon') +const leveldown = require('./your-leveldown') +const fs = require('fs') +const path = require('path') +const testBuffer = fs.readFileSync(path.join(__dirname, 'data/testdata.bin')) +const abstract = require('abstract-leveldown/abstract/put-get-del-test') + +abstract.all(leveldown, test, testBuffer, testCommon) +``` + +to: + +```js +const test = require('tape') +const testCommon = require('abstract-leveldown/testCommon') +const leveldown = require('./your-leveldown') +const abstract = require('abstract-leveldown/abstract/put-get-del-test') + +abstract.all(leveldown, test, testCommon) +``` + +or if `testCommon` is also redundant, to: + +```js +const test = require('tape') +const leveldown = require('./your-leveldown') +const abstract = require('abstract-leveldown/abstract/put-get-del-test') + +abstract.all(leveldown, test) +``` + +#### `.approximateSize` method removed + +The `.approximateSize` method has been removed from the public API. It is heavily related to `LevelDB` and more often than not, other stores lack the native primitives to implement this. If you did implement the internal `_approximateSize` method, that is now dead code. To preserve the method in your public API, rename it to `approximateSize` and also take care of the initialization code. Look to `leveldown` for inspiration. + +Also, the corresponding abstract tests have been removed, so your implementation can no longer require `abstract/approximate-size-test`. + +#### `._isBuffer` method removed + +Because `Buffer` is available in all environments nowadays, there is no need for alternatives like typed arrays. It is preferred to use `Buffer` and `Buffer.isBuffer()` directly. + +#### `isLevelDOWN` function removed + +This was a legacy function. + +#### `ranges-test.js` renamed + +We have refactored a lot of the tests. Specifically the iterator tests were split in two and in that process we renamed `ranges-test.js` to `iterator-range-test.js`. + +If your implementation is using these tests then change from: + +```js +const abstract = require('abstract-leveldown/abstract/ranges-test') +``` + +to: + +```js +const abstract = require('abstract-leveldown/abstract/iterator-range-test') +``` + +## v3 + +No changes to the API. New major version because support for node 0.12 was dropped. diff --git a/nodejs/node_modules/abstract-leveldown/abstract-chained-batch.js

(#1572) +- We are now making heavy use of ES2015 features, this means we have dropped out-of-the-box support for Node 4 and earlier, and many old versions of browsers. (#1541, #1553) +- In `queue`, `priorityQueue`, `cargo` and `cargoQueue`, the "event"-style methods, like `q.drain` and `q.saturated` are now methods that register a callback, rather than properties you assign a callback to. They are now of the form `q.drain(callback)`. If you do not pass a callback a Promise will be returned for the next occurrence of the event, making them `await`-able, e.g. `await q.drain()`. (#1586, #1641) +- Calling `callback(false)` will cancel an async method, preventing further iteration and callback calls. This is useful for preventing memory leaks when you break out of an async flow by calling an outer callback. (#1064, #1542) +- `during` and `doDuring` have been removed, and instead `whilst`, `doWhilst`, `until` and `doUntil` now have asynchronous `test` functions. (#850, #1557) +- `limits` of less than 1 now cause an error to be thrown in queues and collection methods. (#1249, #1552) +- `memoize` no longer memoizes errors (#1465, #1466) +- `applyEach`/`applyEachSeries` have a simpler interface, to make them more easily type-able. It always returns a function that takes in a single callback argument. If that callback is omitted, a promise is returned, making it awaitable. (#1228, #1640) + +## New Features +- Async generators are now supported in all the Collection methods. (#1560) +- Added `cargoQueue`, a queue with both `concurrency` and `payload` size parameters. (#1567) +- Queue objects returned from `queue` now have a `Symbol.iterator` method, meaning they can be iterated over to inspect the current list of items in the queue. (#1459, #1556) +- A ESM-flavored `async.mjs` is included in the `async` package. This is described in the `package.json` `"module"` field, meaning it should be automatically used by Webpack and other compatible bundlers. + +## Bug fixes +- Better handle arbitrary error objects in `asyncify` (#1568, #1569) + +## Other +- Removed Lodash as a dependency (#1283, #1528) +- Miscellaneous docs fixes (#1393, #1501, #1540, #1543, #1558, #1563, #1564, #1579, #1581) +- Miscellaneous test fixes (#1538) + +------- + +# v2.6.1 +- Updated lodash to prevent `npm audit` warnings.

Wherever you can pass a Node-style/CPS function that uses a callback, you can also pass an `async` function. Previously, you had to wrap `async` functions with `asyncify`. The caveat is that it will only work if `async` functions are supported natively in your environment, transpiled implementations can't be detected.

Special thanks to [**@hargasinski**](https://github.com/hargasinski) for his work converting our old docs to `jsdoc` format and implementing the new website. Also huge ups to [**@ivanseidel**](https://github.com/ivanseidel) for designing our new logo. It was a long process for both of these tasks, but I think these changes turned out extraordinary well. + +The biggest feature is modularization. You can now `require("async/series")` to only require the `series` function. Every Async library function is available this way. You still can `require("async")` to require the entire library, like you could do before. + +We also provide Async as a collection of ES2015 modules. You can now `import {each} from 'async-es'` or `import waterfall from 'async-es/waterfall'`. If you are using only a few Async functions, and are using a ES bundler such as Rollup, this can significantly lower your build size. + +Major thanks to [**@Kikobeats**](github.com/Kikobeats), [**@aearly**](github.com/aearly) and [**@megawac**](github.com/megawac) for doing the majority of the modularization work, as well as [**@jdalton**](github.com/jdalton) and [**@Rich-Harris**](github.com/Rich-Harris) for advisory work on the general modularization strategy. + +Another one of the general themes of the 2.0 release is standardization of what an "async" function is. We are now more strictly following the node-style continuation passing style. That is, an async function is a function that: + +1. Takes a variable number of arguments +2. The last argument is always a callback +3. The callback can accept any number of arguments +4. The first argument passed to the callback will be treated as an error result, if the argument is truthy +5. Any number of result arguments can be passed after the "error" argument +6. The callback is called once and exactly once, either on the same tick or later tick of the JavaScript event loop. + +There were several cases where Async accepted some functions that did not strictly have these properties, most notably `auto`, `every`, `some`, `filter`, `reject` and `detect`. + +Another theme is performance. We have eliminated internal deferrals in all cases where they make sense. For example, in `waterfall` and `auto`, there was a `setImmediate` between each task -- these deferrals have been removed. A `setImmediate` call can add up to 1ms of delay. This might not seem like a lot, but it can add up if you are using many Async functions in the course of processing a HTTP request, for example. Nearly all asynchronous functions that do I/O already have some sort of deferral built in, so the extra deferral is unnecessary. The trade-off of this change is removing our built-in stack-overflow defense. Many synchronous callback calls in series can quickly overflow the JS call stack. If you do have a function that is sometimes synchronous (calling its callback on the same tick), and are running into stack overflows, wrap it with `async.ensureAsync()`. + +Another big performance win has been re-implementing `queue`, `cargo`, and `priorityQueue` with [doubly linked lists](https://en.wikipedia.org/wiki/Doubly_linked_list) instead of arrays. This has lead to queues being an order of [magnitude faster on large sets of tasks](https://github.com/caolan/async/pull/1205). + +## New Features + +- Async is now modularized. Individual functions can be `require()`d from the main package. (`require('async/auto')`) ([#984](https://github.com/caolan/async/issues/984), [#996](https://github.com/caolan/async/issues/996)) +- Async is also available as a collection of ES2015 modules in the new `async-es` package. (`import {forEachSeries} from 'async-es'`) ([#984](https://github.com/caolan/async/issues/984), [#996](https://github.com/caolan/async/issues/996)) +- Added `race`, analogous to `Promise.race()`. It will run an array of async tasks in parallel and will call its callback with the result of the first task to respond. ([#568](https://github.com/caolan/async/issues/568), [#1038](https://github.com/caolan/async/issues/1038)) +- Collection methods now accept ES2015 iterators. Maps, Sets, and anything that implements the iterator spec can now be passed directly to `each`, `map`, `parallel`, etc.. ([#579](https://github.com/caolan/async/issues/579), [#839](https://github.com/caolan/async/issues/839), [#1074](https://github.com/caolan/async/issues/1074)) +- Added `mapValues`, for mapping over the properties of an object and returning an object with the same keys. ([#1157](https://github.com/caolan/async/issues/1157), [#1177](https://github.com/caolan/async/issues/1177)) +- Added `timeout`, a wrapper for an async function that will make the task time-out after the specified time. ([#1007](https://github.com/caolan/async/issues/1007), [#1027](https://github.com/caolan/async/issues/1027)) +- Added `reflect` and `reflectAll`, analagous to [`Promise.reflect()`](http://bluebirdjs.com/docs/api/reflect.html), a wrapper for async tasks that always succeeds, by gathering results and errors into an object. ([#942](https://github.com/caolan/async/issues/942), [#1012](https://github.com/caolan/async/issues/1012), [#1095](https://github.com/caolan/async/issues/1095)) +- `constant` supports dynamic arguments -- it will now always use its last argument as the callback. ([#1016](https://github.com/caolan/async/issues/1016), [#1052](https://github.com/caolan/async/issues/1052)) +- `setImmediate` and `nextTick` now support arguments to partially apply to the deferred function, like the node-native versions do. ([#940](https://github.com/caolan/async/issues/940), [#1053](https://github.com/caolan/async/issues/1053)) +- `auto` now supports resolving cyclic dependencies using [Kahn's algorithm](https://en.wikipedia.org/wiki/Topological_sorting#Kahn.27s_algorithm) ([#1140](https://github.com/caolan/async/issues/1140)). +- Added `autoInject`, a relative of `auto` that automatically spreads a task's dependencies as arguments to the task function. ([#608](https://github.com/caolan/async/issues/608), [#1055](https://github.com/caolan/async/issues/1055), [#1099](https://github.com/caolan/async/issues/1099), [#1100](https://github.com/caolan/async/issues/1100)) +- You can now limit the concurrency of `auto` tasks. ([#635](https://github.com/caolan/async/issues/635), [#637](https://github.com/caolan/async/issues/637)) +- Added `retryable`, a relative of `retry` that wraps an async function, making it retry when called. ([#1058](https://github.com/caolan/async/issues/1058)) +- `retry` now supports specifying a function that determines the next time interval, useful for exponential backoff, logging and other retry strategies. ([#1161](https://github.com/caolan/async/issues/1161)) +- `retry` will now pass all of the arguments the task function was resolved with to the callback ([#1231](https://github.com/caolan/async/issues/1231)). +- Added `q.unsaturated` -- callback called when a `queue`'s number of running workers falls below a threshold. ([#868](https://github.com/caolan/async/issues/868), [#1030](https://github.com/caolan/async/issues/1030), [#1033](https://github.com/caolan/async/issues/1033), [#1034](https://github.com/caolan/async/issues/1034)) +- Added `q.error` -- a callback called whenever a `queue` task calls its callback with an error. ([#1170](https://github.com/caolan/async/issues/1170)) +- `applyEach` and `applyEachSeries` now pass results to the final callback. ([#1088](https://github.com/caolan/async/issues/1088)) + +## Breaking changes + +- Calling a callback more than once is considered an error, and an error will be thrown. This had an explicit breaking change in `waterfall`. If you were relying on this behavior, you should more accurately represent your control flow as an event emitter or stream. ([#814](https://github.com/caolan/async/issues/814), [#815](https://github.com/caolan/async/issues/815), [#1048](https://github.com/caolan/async/issues/1048), [#1050](https://github.com/caolan/async/issues/1050)) +- `auto` task functions now always take the callback as the last argument. If a task has dependencies, the `results` object will be passed as the first argument. To migrate old task functions, wrap them with [`_.flip`](https://lodash.com/docs#flip) ([#1036](https://github.com/caolan/async/issues/1036), [#1042](https://github.com/caolan/async/issues/1042)) +- Internal `setImmediate` calls have been refactored away. This may make existing flows vulnerable to stack overflows if you use many synchronous functions in series. Use `ensureAsync` to work around this. ([#696](https://github.com/caolan/async/issues/696), [#704](https://github.com/caolan/async/issues/704), [#1049](https://github.com/caolan/async/issues/1049), [#1050](https://github.com/caolan/async/issues/1050)) +- `map` used to return an object when iterating over an object. `map` now always returns an array, like in other libraries. The previous object behavior has been split out into `mapValues`. ([#1157](https://github.com/caolan/async/issues/1157), [#1177](https://github.com/caolan/async/issues/1177)) +- `filter`, `reject`, `some`, `every`, `detect` and their families like `{METHOD}Series` and `{METHOD}Limit` now expect an error as the first callback argument, rather than just a simple boolean. Pass `null` as the first argument, or use `fs.access` instead of `fs.exists`. ([#118](https://github.com/caolan/async/issues/118), [#774](https://github.com/caolan/async/issues/774), [#1028](https://github.com/caolan/async/issues/1028), [#1041](https://github.com/caolan/async/issues/1041)) +- `{METHOD}` and `{METHOD}Series` are now implemented in terms of `{METHOD}Limit`. This is a major internal simplification, and is not expected to cause many problems, but it does subtly affect how functions execute internally. ([#778](https://github.com/caolan/async/issues/778), [#847](https://github.com/caolan/async/issues/847)) +- `retry`'s callback is now optional. Previously, omitting the callback would partially apply the function, meaning it could be passed directly as a task to `series` or `auto`. The partially applied "control-flow" behavior has been separated out into `retryable`. ([#1054](https://github.com/caolan/async/issues/1054), [#1058](https://github.com/caolan/async/issues/1058)) +- The test function for `whilst`, `until`, and `during` used to be passed non-error args from the iteratee function's callback, but this led to weirdness where the first call of the test function would be passed no args. We have made it so the test function is never passed extra arguments, and only the `doWhilst`, `doUntil`, and `doDuring` functions pass iteratee callback arguments to the test function ([#1217](https://github.com/caolan/async/issues/1217), [#1224](https://github.com/caolan/async/issues/1224)) +- The `q.tasks` array has been renamed `q._tasks` and is now implemented as a doubly linked list (DLL). Any code that used to interact with this array will need to be updated to either use the provided helpers or support DLLs ([#1205](https://github.com/caolan/async/issues/1205)). +- The timing of the `q.saturated()` callback in a `queue` has been modified to better reflect when tasks pushed to the queue will start queueing. ([#724](https://github.com/caolan/async/issues/724), [#1078](https://github.com/caolan/async/issues/1078)) +- Removed `iterator` method in favour of [ES2015 iterator protocol](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Iterators_and_Generators ) which natively supports arrays ([#1237](https://github.com/caolan/async/issues/1237)) +- Dropped support for Component, Jam, SPM, and Volo ([#1175](https://github.com/caolan/async/issues/1175), #[#176](https://github.com/caolan/async/issues/176)) + +## Bug Fixes + +- Improved handling of no dependency cases in `auto` & `autoInject` ([#1147](https://github.com/caolan/async/issues/1147)). +- Fixed a bug where the callback generated by `asyncify` with `Promises` could resolve twice ([#1197](https://github.com/caolan/async/issues/1197)). +- Fixed several documented optional callbacks not actually being optional ([#1223](https://github.com/caolan/async/issues/1223)). + +## Other + +- Added `someSeries` and `everySeries` for symmetry, as well as a complete set of `any`/`anyLimit`/`anySeries` and `all`/`/allLmit`/`allSeries` aliases. +- Added `find` as an alias for `detect.

browser). + * If you are using `async` functions through a transpiler (e.g. Babel), you + * must still wrap the function with [asyncify]{@link module:Utils.asyncify}, + * because the `async function`

The callback should be called with a + * Error as its first argument to signal that an error occurred. + * Otherwise, if no error occurred, it should be called with `null` as the first + * argument, and any additional `result` arguments that may apply, to signal + * successful completion. + * The callback must be called exactly once, ideally on a later tick of the + * JavaScript event loop. + * + * This type of function is also referred to as a "Node-style async function", + * or a "continuation passing-style function" (CPS).

We guarantee `BSONError.isBSONError()` checks will pass according to semver guidelines, but errors may be sub-classed or their messages may change at any time, even patch releases, as we see fit to increase the helpfulness of the errors. + +Any new errors we add to the driver will directly extend an existing error class and no existing error will be moved to a different parent class outside of a major release. +This means `BSONError.isBSONError()` will always be able to accurately capture the errors that our BSON library throws. + +Hypothetical example: A collection in our Db has an issue with UTF-8 data: + +```ts +let documentCount = 0; +const cursor = collection.find({}, { utf8Validation: true }); +try { + for await (const doc of cursor) documentCount += 1; +} catch (error) { + if (BSONError.isBSONError(error)) { + console.log(`Found the troublemaker UTF-8!: ${documentCount} ${error.message}`); + return documentCount; + } + throw error; +} +``` + +## React Native + +BSON vendors the required polyfills for `TextEncoder`, `TextDecoder`, `atob`, `btoa` imported from React Native and therefore doesn't expect users to polyfill these. One additional polyfill, `crypto.getRandomValues` is recommended and can be installed with the following command: + +```sh +npm install --save react-native-get-random-values +``` + +The following snippet should be placed at the top of the entrypoint (by default this is the root `index.js` file) for React Native projects using the BSON library. These lines must be placed for any code that imports `BSON`. + +```typescript +// Required Polyfills For ReactNative +import 'react-native-get-random-values'; +``` + +Finally, import the `BSON` library like so: + +```typescript +import { BSON, EJSON } from 'bson'; +``` + +This will cause React Native to import the `node_modules/bson/lib/bson.rn.cjs` bundle (see the `"react-native"` setting we have in the `"exports"` section of our [package.json](./package.json).) + +### Technical Note about React Native module import + +The `"exports"` definition in our `package.json` will result in BSON's CommonJS bundle being imported in a React Native project instead of the ES module bundle. Importing the CommonJS bundle is necessary because BSON's ES module bundle of BSON uses top-level await, which is not supported syntax in [React Native's runtime hermes](https://hermesengine.dev/). + +## FAQ + +#### Why does `undefined` get converted to `null`? + +The `undefined` BSON type has been [deprecated for many years](http://bsonspec.org/spec.html), so this library has dropped support for it. Use the `ignoreUndefined` option (for example, from the [driver](http://mongodb.github.io/node-mongodb-native/2.2/api/MongoClient.html#connect) ) to instead remove `undefined` keys. + +#### How do I add custom serialization logic? + +This library looks for `toBSON()` functions on every path, and calls the `toBSON()` function to get the value to serialize. + +```javascript +const BSON = require('bson'); + +class CustomSerialize { + toBSON() { + return 42; + } +} + +const obj = { answer: new CustomSerialize() }; +// "{ answer: 42 }" +console.log(BSON.deserialize(BSON.serialize(obj))); +``` diff --git a/nodejs/node_modules/bson/bson.d.ts b/nodejs/node_modules/bson/bson.d.ts new file mode 100644 index 00000000..e41feef9 --- /dev/null +++ b/nodejs/node_modules/bson/bson.d.ts @@ -0,0 +1,1390 @@ +/** + * A class representation of the BSON Binary type. + * @public + * @category BSONType + */ +export declare class Binary extends BSONValue { + get _bsontype(): 'Binary';

Square bracket notation works as expected -- it returns a +single octet. + +The `Uint8Array` prototype remains unmodified. + + +## tracking the latest node api + +This module tracks the Buffer API in the latest (unstable) version of node.js. The Buffer +API is considered **stable** in the +[node stability index](https://nodejs.org/docs/latest/api/documentation.html#documentation_stability_index), +so it is unlikely that there will ever be breaking changes. +Nonetheless, when/if the Buffer API changes in node, this module's API will change +accordingly. + +## related packages + +- [`buffer-reverse`](https://www.npmjs.com/package/buffer-reverse) - Reverse a buffer +- [`buffer-xor`](https://www.npmjs.com/package/buffer-xor) - Bitwise xor a buffer +- [`is-buffer`](https://www.npmjs.com/package/is-buffer) - Determine if an object is a Buffer without including the whole `Buffer` package + +## conversion packages + +### convert typed array to buffer + +Use [`typedarray-to-buffer`](https://www.npmjs.com/package/typedarray-to-buffer) to convert any kind of typed array to a `Buffer`.

Other types, though accepted, are [_serialized_](https://github.com/Level/abstract-leveldown#db_serializekeykey) before storage, which is an irreversible type conversion. For a richer set of data types you can wrap such a store with `encoding-down`. It allows you to specify an _encoding_ to use for keys and values independently. This not only widens the range of input types, but also limits the range of output types. The encoding is applied to all read and write operations: it encodes writes and decodes reads. + +[Many encodings are builtin][builtin-encodings] courtesy of [`level-codec`][level-codec]. The default encoding is `utf8` which ensures you'll always get back a string. You can also provide a custom encoding like `bytewise` - [or your own](#custom-encodings)! + +## Usage + +Without any options, `encoding-down` defaults to the `utf8` encoding. + +```js +var levelup = require('levelup') +var leveldown = require('leveldown') +var encode = require('encoding-down') + +var db = levelup(encode(leveldown('./db1'))) + +db.put('example', Buffer.from('encoding-down'), function (err) { + db.get('example', function (err, value) { + console.log(typeof value, value) // 'string encoding-down' + }) +}) +``` + +Can we store objects? Yes! + +```js +var db = levelup(encode(leveldown('./db2'), { valueEncoding: 'json' })) + +db.put('example', { awesome: true }, function (err) { + db.get('example', function (err, value) { + console.log(value) // { awesome: true } + console.log(typeof value) // 'object' + }) +}) +``` + +How about storing Buffers, but getting back a hex-encoded string? + +```js +var db = levelup(encode(leveldown('./db3'), { valueEncoding: 'hex' })) + +db.put('example', Buffer.from([0, 255]), function (err) { + db.get('example', function (err, value) { + console.log(typeof value, value) // 'string 00ff' + }) +}) +``` + +What if we previously stored binary data? + +```js +var db = levelup(encode(leveldown('./db4'), { valueEncoding: 'binary' })) + +db.put('example', Buffer.from([0, 255]), function (err) { + db.get('example', function (err, value) { + console.log(typeof value, value) // 'object ' + }) + + // Override the encoding for this operation + db.get('example', { valueEncoding: 'base64' }, function (err, value) { + console.log(typeof value, value) // 'string AP8=' + }) +}) +``` + +And what about keys? + +```js +var db = levelup(encode(leveldown('./db5'), { keyEncoding: 'json' })) + +db.put({ awesome: true }, 'example', function (err) { + db.get({ awesome: true }, function (err, value) { + console.log(value) // 'example' + }) +}) +``` + +```js +var db = levelup(encode(leveldown('./db6'), { keyEncoding: 'binary' })) + +db.put(Buffer.from([0, 255]), 'example', function (err) { + db.get('00ff', { keyEncoding: 'hex' }, function (err, value) { + console.log(value) // 'example' + }) +}) +``` + +## Usage with [`level`][level] + +The [`level`][level] module conveniently bundles `encoding-down` and passes its `options` to `encoding-down`. This means you can simply do: + +```js +var level = require('level') +var db = level('./db7', { valueEncoding: 'json' }) + +db.put('example', 42, function (err) { + db.get('example', function (err, value) { + console.log(value) // 42 + console.log(typeof value) // 'number' + }) +}) +``` + +## API + +### `db = require('encoding-down')(db[, options])` + +- `db` must be an [`abstract-leveldown`][abstract-leveldown] compliant store +- `options` are passed to [`level-codec`][level-codec]: + - `keyEncoding`: encoding to use for keys + - `valueEncoding`: encoding to use for values + +Both encodings default to `'utf8'`. They can be a string (builtin `level-codec` encoding) or an object (custom encoding). + +## Custom encodings + +Please refer to [`level-codec` documentation][encoding-format] for a precise description of the format. Here's a quick example with `level` and `async/await` just for fun: + +```js +var level = require('level') +var lexint = require('lexicographic-integer') + +async function main () { + var db = level('./db8', { + keyEncoding: { + type: 'lexicographic-integer', + encode: (n) => lexint.pack(n, 'hex'), + decode: lexint.unpack, + buffer: false + } + }) + + await db.put(2, 'example') + await db.put(10, 'example') + + // Without our encoding, the keys would sort as 10, 2. + db.createKeyStream().on('data', console.log) // 2, 10 +} + +main() +``` + +With an npm-installed encoding (modularity ftw!) we can reduce the above to: + +```js +var level = require('level') +var lexint = require('lexicographic-integer-encoding')('hex') + +var db = level('./db8', { + keyEncoding: lexint +}) +``` + +## Contributing + +[`Level/encoding-down`](https://github.com/Level/encoding-down) is an **OPEN Open Source Project**.

Since `format.combine` takes no `opts`, as a convenience it returns pre-created instance of the combined format. + +``` js +const { format } = require('logform'); +const { combine, timestamp, label } = format; + +const labelTimestamp = combine( + label({ label: 'right meow!' }), + timestamp() +); + +const info = labelTimestamp.transform({ + level: 'info', + message: 'What time is the testing at?' +}); + +console.dir(info); +// { level: 'info', +// message: 'What time is the testing at?', +// label: 'right meow!', +// timestamp: '2017-09-30T03:57:26.875Z' } +``` + +### Filtering `info` Objects + +If you wish to filter out a given `info` Object completely then simply return a falsey value. + +``` js +const ignorePrivate = format((info, opts) => { + if (info.private) { return false; } + return info; +}); + +console.dir(ignorePrivate.transform({ + level: 'error', + message: 'Public error to share' +})); +// { level: 'error', message: 'Public error to share' } + +console.dir(ignorePrivate.transform({ + level: 'error', + private: true, + message: 'This is super secret - hide it.' +})); +// false +``` + +Use of `format.combine` will respect any falsey values return and stop evaluation of later formats in the series. For example: + +``` js +const { format } = require('logform'); +const { combine, timestamp, label } = format; + +const willNeverThrow = format.combine( + format(info => { return false })(), // Ignores everything + format(info => { throw new Error('Never reached') })() +); + +console.dir(willNeverThrow.transform({ + level: 'info', + message: 'wow such testing' +})) +``` + +## Formats + +### Align + +The `align` format adds a `\t` delimiter before the message to align it in the same place. + +```js +const { format } = require('logform'); + +const alignFormat = format.align(); + +const info = alignFormat.transform({ + level: 'info', + message: 'my message' +}); + +console.log(info); +// { level: 'info', message: '\tmy message' } +``` + +This was previously exposed as `{ align: true }` in `winston < 3.0.0`. + +### CLI + +The `cli` format is a combination of the `colorize` and the `padLevels` formats.

+await client.connect(); +const collection = client.db().collection('collection'); + +try { + await collection.insertOne({ _id: 1 }); + await collection.insertOne({ _id: 1 }); // duplicate key error +} catch (error) { + if (error instanceof MongoServerError) { + console.log(`Error worth logging: ${error}`); // special case for some reason + } + throw error; // still want to crash +} +``` + +## Nightly releases + +If you need to test with a change from the latest `main` branch our `mongodb` npm package has nightly versions released under the `nightly` tag. + +```sh +npm install mongodb@nightly +``` + +Nightly versions are published regardless of testing outcome. +This means there could be sematic breakages or partially implemented features. +The nightly build is not suitable for production use. + +## Next Steps + +- [MongoDB Documentation](https://www.mongodb.com/docs/manual/) +- [MongoDB Node Driver Documentation](https://www.mongodb.com/docs/drivers/node/) +- [Read about Schemas](https://www.mongodb.com/docs/manual/core/data-modeling-introduction/) +- [Star us on GitHub](https://github.com/mongodb/node-mongodb-native) + +## License + +[Apache 2.0](LICENSE.md) + +© 2012-present MongoDB [Contributors](https://github.com/mongodb/node-mongodb-native/blob/HEAD/CONTRIBUTORS.md) \ +© 2009-2012 Christian Amor Kvalheim diff --git a/nodejs/node_modules/mongodb/etc/prepare.js b/nodejs/node_modules/mongodb/etc/prepare.js new file mode 100755 index 00000000..2039d0b3 --- /dev/null +++ b/nodejs/node_modules/mongodb/etc/prepare.js @@ -0,0 +1,12 @@ +#! /usr/bin/env node +var cp = require('child_process');

These +individuals are identified by the WG and their addition as +Collaborators is discussed during the WG meeting. + +_Note:_ If you make a significant contribution and are not considered +for commit-access log an issue or contact a WG member directly and it +will be brought up in the next WG meeting. + +Modifications of the contents of the readable-stream repository are +made on +a collaborative basis. Anybody with a GitHub account may propose a +modification via pull request and it will be considered by the project +Collaborators. All pull requests must be reviewed and accepted by a +Collaborator with sufficient expertise who is able to take full +responsibility for the change. In the case of pull requests proposed +by an existing Collaborator, an additional Collaborator is required +for sign-off. Consensus should be sought if additional Collaborators +participate and there is disagreement around a particular +modification. See _Consensus Seeking Process_ below for further detail +on the consensus model used for governance. + +Collaborators may opt to elevate significant or controversial +modifications, or modifications that have not found consensus to the +WG for discussion by assigning the ***WG-agenda*** tag to a pull +request or issue. The WG should serve as the final arbiter where +required. + +For the current list of Collaborators, see the project +[README.md](./README.md#members). + +### WG Membership + +WG seats are not time-limited. There is no fixed size of the WG. +However, the expected target is between 6 and 12, to ensure adequate +coverage of important areas of expertise, balanced with the ability to +make decisions efficiently. + +There is no specific set of requirements or qualifications for WG +membership beyond these rules. + +The WG may add additional members to the WG by unanimous consensus. + +A WG member may be removed from the WG by voluntary resignation, or by +unanimous consensus of all other WG members. + +Changes to WG membership should be posted in the agenda, and may be +suggested as any other agenda item (see "WG Meetings" below). + +If an addition or removal is proposed during a meeting, and the full +WG is not in attendance to participate, then the addition or removal +is added to the agenda for the subsequent meeting. This is to ensure +that all members are given the opportunity to participate in all +membership decisions. If a WG member is unable to attend a meeting +where a planned membership decision is being made, then their consent +is assumed. + +No more than 1/3 of the WG members may be affiliated with the same +employer. If removal or resignation of a WG member, or a change of +employment by a WG member, creates a situation where more than 1/3 of +the WG membership shares an employer, then the situation must be +immediately remedied by the resignation or removal of one or more WG +members affiliated with the over-represented employer(s). + +### WG Meetings + +The WG meets occasionally on a Google Hangout On Air. A designated moderator +approved by the WG runs the meeting. Each meeting should be +published to YouTube. + +Items are added to the WG agenda that are considered contentious or +are modifications of governance, contribution policy, WG membership, +or release process. + +The intention of the agenda is not to approve or review all patches; +that should happen continuously on GitHub and be handled by the larger +group of Collaborators. + +Any community member or contributor can ask that something be added to +the next meeting's agenda by logging a GitHub Issue. Any Collaborator, +WG member or the moderator can add the item to the agenda by adding +the ***WG-agenda*** tag to the issue. + +Prior to each WG meeting the moderator will share the Agenda with +members of the WG. WG members can add any items they like to the +agenda at the beginning of each meeting. The moderator and the WG +cannot veto or remove items. + +The WG may invite persons or representatives from certain projects to +participate in a non-voting capacity. + +The moderator is responsible for summarizing the discussion of each +agenda item and sends it as a pull request after the meeting. + +### Consensus Seeking Process + +The WG follows a +[Consensus +Seeking](http://en.wikipedia.org/wiki/Consensus-seeking_decision-making) +decision-making model. + +When an agenda item has appeared to reach a consensus the moderator +will ask "Does anyone object?" as a final call for dissent from the +consensus. + +If an agenda item cannot reach a consensus a WG member can call for +either a closing vote or a vote to table the issue to the next +meeting. The call for a vote must be seconded by a majority of the WG +or else the discussion will continue. Simple majority wins. + +Note that changes to WG membership require a majority consensus.

Sometimes it's called a "filter", +// but that's not a great name for it, since that implies a thing where +// some bits pass through, and others are simply ignored. (That would +// be a valid example of a transform, of course.) +// +// While the output is causally related to the input, it's not a +// necessarily symmetric or synchronous transformation. For example, +// a zlib stream might take multiple plain-text writes(), and then +// emit a single compressed chunk some time in the future. +// +// Here's how this works: +// +// The Transform stream has all the aspects of the readable and writable +// stream classes. When you write(chunk), that calls _write(chunk,cb) +// internally, and returns false if there's a lot of pending writes +// buffered up. When you call read(), that calls _read(n) until +// there's enough pending readable data buffered up. +// +// In a transform stream, the written data is placed in a buffer. When +// _read(n) is called, it transforms the queued up data, calling the +// buffered _write cb's as it consumes chunks. If consuming a single +// written chunk would result in multiple output chunks, then the first +// outputted bit calls the readcb, and subsequent chunks just go into +// the read buffer, and will cause it to emit 'readable' if necessary. +// +// This way, back-pressure is actually determined by the reading side, +// since _read has to be called to start processing a new chunk. However, +// a pathological inflate type of transform can cause excessive buffering +// here. For example, imagine a stream where every byte of input is +// interpreted as an integer from 0-255, and then results in that many +// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in +// 1kb of data being output. In this case, you could write a very small +// amount of input, and end up with a very large amount of output. In +// such a pathological inflating mechanism, there'd be no way to tell +// the system to stop doing the transform. A single 4MB write could +// cause the system to run out of memory. +// +// However, even in such a pathological case, only a single written chunk +// would be consumed, and then the rest would wait (un-transformed) until +// the results of the previous transformed chunk were consumed. + +'use strict'; + +module.exports = Transform; +var _require$codes = require('../errors').codes, + ERR_METHOD_NOT_IMPLEMENTED = _require$codes.ERR_METHOD_NOT_IMPLEMENTED, + ERR_MULTIPLE_CALLBACK = _require$codes.ERR_MULTIPLE_CALLBACK, + ERR_TRANSFORM_ALREADY_TRANSFORMING = _require$codes.ERR_TRANSFORM_ALREADY_TRANSFORMING, + ERR_TRANSFORM_WITH_LENGTH_0 = _require$codes.ERR_TRANSFORM_WITH_LENGTH_0; +var Duplex = require('./_stream_duplex'); +require('inherits')(Transform, Duplex); +function afterTransform(er, data) { + var ts = this._transformState; + ts.transforming = false; + var cb = ts.writecb; + if (cb === null) { + return this.emit('error', new ERR_MULTIPLE_CALLBACK()); + } + ts.writechunk = null; + ts.writecb = null; + if (data != null) + // single equals check for both `null` and `undefined` + this.push(data); + cb(er); + var rs = this._readableState; + rs.reading = false; + if (rs.needReadable || rs.length < rs.highWaterMark) { + this._read(rs.highWaterMark); + } +} +function Transform(options) { + if (!(this instanceof Transform)) return new Transform(options); + Duplex.call(this, options); + this._transformState = { + afterTransform: afterTransform.bind(this), + needTransform: false, + transforming: false, + writecb: null, + writechunk: null, + writeencoding: null + }; + + // start out asking for a readable event once data is transformed. + this._readableState.needReadable = true; + + // we have implemented the _read method, and done the other things + // that Readable wants before the first _read call, so unset the + // sync guard flag. + this._readableState.sync = false; + if (options) { + if (typeof options.transform === 'function') this._transform = options.transform; + if (typeof options.flush === 'function') this._flush = options.flush; + } + + // When the writable side finishes, then flush out anything remaining. + this.on('prefinish', prefinish); +} +function prefinish() { + var _this = this; + if (typeof this._flush === 'function' && !this._readableState.destroyed) { + this._flush(function (er, data) { + done(_this, er, data); + }); + } else { + done(this, null, null); + } +} +Transform.prototype.push = function (chunk, encoding) { + this._transformState.needTransform = false; + return Duplex.prototype.push.call(this, chunk, encoding); +}; + +// This is the part where you do stuff! +// override this function in implementation classes. +// 'chunk' is an input chunk. +// +// Call `push(newChunk)` to pass along transformed output +// to the readable side.

The +difference is subtle but can be important when an application requires the +additional performance that `Buffer.allocUnsafe(size)` provides. + +### Class Method: Buffer.allocUnsafeSlow(size) + + +* `size` {Number} + +Allocates a new *non-zero-filled* and non-pooled `Buffer` of `size` bytes.

The contents of the newly created `Buffer` are unknown and +*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such +`Buffer` instances to zeroes. + +When using `Buffer.allocUnsafe()` to allocate new `Buffer` instances, +allocations under 4KB are, by default, sliced from a single pre-allocated +`Buffer`. This allows applications to avoid the garbage collection overhead of +creating many individually allocated Buffers. This approach improves both +performance and memory usage by eliminating the need to track and cleanup as +many `Persistent` objects. + +However, in the case where a developer may need to retain a small chunk of +memory from a pool for an indeterminate amount of time, it may be appropriate +to create an un-pooled Buffer instance using `Buffer.allocUnsafeSlow()` then +copy out the relevant bits. + +```js +// need to keep around a few small chunks of memory +const store = []; + +socket.on('readable', () => { + const data = socket.read(); + // allocate for retained data + const sb = Buffer.allocUnsafeSlow(10); + // copy the data into the new allocation + data.copy(sb, 0, 0, 10); + store.push(sb); +}); +``` + +Use of `Buffer.allocUnsafeSlow()` should be used only as a last resort *after* +a developer has observed undue memory retention in their applications. + +A `TypeError` will be thrown if `size` is not a number. + +### All the Rest + +The rest of the `Buffer` API is exactly the same as in node.js. +[See the docs](https://nodejs.org/api/buffer.html). + + +## Related links + +- [Node.js issue: Buffer(number) is unsafe](https://github.com/nodejs/node/issues/4660) +- [Node.js Enhancement Proposal: Buffer.from/Buffer.alloc/Buffer.zalloc/Buffer() soft-deprecate](https://github.com/nodejs/node-eps/pull/4) + +## Why is `Buffer` unsafe? + +Today, the node.js `Buffer` constructor is overloaded to handle many different argument +types like `String`, `Array`, `Object`, `TypedArrayView` (`Uint8Array`, etc.), +`ArrayBuffer`, and also `Number`. + +The API is optimized for convenience: you can throw any type at it, and it will try to do +what you want. + +Because the Buffer constructor is so powerful, you often see code like this: + +```js +// Convert UTF-8 strings to hex +function toHex (str) { + return new Buffer(str).toString('hex') +} +``` + +***But what happens if `toHex` is called with a `Number` argument?*** + +### Remote Memory Disclosure + +If an attacker can make your program call the `Buffer` constructor with a `Number` +argument, then they can make it allocate uninitialized memory from the node.js process. +This could potentially disclose TLS private keys, user data, or database passwords. + +When the `Buffer` constructor is passed a `Number` argument, it returns an +**UNINITIALIZED** block of memory of the specified `size`. When you create a `Buffer` like +this, you **MUST** overwrite the contents before returning it to the user. + +From the [node.js docs](https://nodejs.org/api/buffer.html#buffer_new_buffer_size): + +> `new Buffer(size)` +> +> - `size` Number +> +> The underlying memory for `Buffer` instances created in this way is not initialized. +> **The contents of a newly created `Buffer` are unknown and could contain sensitive +> data.** Use `buf.fill(0)` to initialize a Buffer to zeroes. + +(Emphasis our own.) + +Whenever the programmer intended to create an uninitialized `Buffer` you often see code +like this: + +```js +var buf = new Buffer(16) + +// Immediately overwrite the uninitialized buffer with data from another buffer +for (var i = 0; i < buf.length; i++) { + buf[i] = otherBuf[i] +} +``` + + +### Would this ever be a problem in real code? + +Yes. It's surprisingly common to forget to check the type of your variables in a +dynamically-typed language like JavaScript. + +Usually the consequences of assuming the wrong type is that your program crashes with an +uncaught exception. But the failure mode for forgetting to check the type of arguments to +the `Buffer` constructor is more catastrophic. + +Here's an example of a vulnerable service that takes a JSON payload and converts it to +hex: + +```js +// Take a JSON payload {str: "some string"} and convert it to hex +var server = http.createServer(function (req, res) { + var data = '' + req.setEncoding('utf8') + req.on('data', function (chunk) { + data += chunk + }) + req.on('end', function () { + var body = JSON.parse(data) + res.end(new Buffer(body.str).toString('hex')) + }) +}) + +server.listen(8080) +``` + +In this example, an http client just has to send: + +```json +{ + "str": 1000 +} +``` + +and it will get back 1,000 bytes of uninitialized memory from the server. + +This is a very serious bug. It's similar in severity to the +[the Heartbleed bug](http://heartbleed.com/) that allowed disclosure of OpenSSL process +memory by remote attackers. + + +### Which real-world packages were vulnerable? + +#### [`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht) + +[Mathias Buus](https://github.com/mafintosh) and I +([Feross Aboukhadijeh](http://feross.org/)) found this issue in one of our own packages, +[`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht). The bug would allow +anyone on the internet to send a series of messages to a user of `bittorrent-dht` and get +them to reveal 20 bytes at a time of uninitialized memory from the node.js process. + +Here's +[the commit](https://github.com/feross/bittorrent-dht/commit/6c7da04025d5633699800a99ec3fbadf70ad35b8) +that fixed it. We released a new fixed version, created a +[Node Security Project disclosure](https://nodesecurity.io/advisories/68), and deprecated all +vulnerable versions on npm so users will get a warning to upgrade to a newer version. + +#### [`ws`](https://www.npmjs.com/package/ws) + +That got us wondering if there were other vulnerable packages. Sure enough, within a short +period of time, we found the same issue in [`ws`](https://www.npmjs.com/package/ws), the +most popular WebSocket implementation in node.js. + +If certain APIs were called with `Number` parameters instead of `String` or `Buffer` as +expected, then uninitialized server memory would be disclosed to the remote peer. + +These were the vulnerable methods: + +```js +socket.send(number) +socket.ping(number) +socket.pong(number) +``` + +Here's a vulnerable socket server with some echo functionality: + +```js +server.on('connection', function (socket) { + socket.on('message', function (message) { + message = JSON.parse(message) + if (message.type === 'echo') { + socket.send(message.data) // send back the user's message + } + }) +}) +``` + +`socket.send(number)` called on the server, will disclose server memory. + +Here's [the release](https://github.com/websockets/ws/releases/tag/1.0.1) where the issue +was fixed, with a more detailed explanation. Props to +[Arnout Kazemier](https://github.com/3rd-Eden) for the quick fix. Here's the +[Node Security Project disclosure](https://nodesecurity.io/advisories/67). + + +### What's the solution? + +It's important that node.js offers a fast way to get memory otherwise performance-critical +applications would needlessly get a lot slower. + +But we need a better way to *signal our intent* as programmers. **When we want +uninitialized memory, we should request it explicitly.** + +Sensitive functionality should not be packed into a developer-friendly API that loosely +accepts many different types. This type of API encourages the lazy practice of passing +variables in without checking the type very carefully. + +#### A new API: `Buffer.allocUnsafe(number)` + +The functionality of creating buffers with uninitialized memory should be part of another +API. We propose `Buffer.allocUnsafe(number)`. This way, it's not part of an API that +frequently gets user input of all sorts of different types passed into it. + +```js +var buf = Buffer.allocUnsafe(16) // careful, uninitialized memory! + +// Immediately overwrite the uninitialized buffer with data from another buffer +for (var i = 0; i < buf.length; i++) { + buf[i] = otherBuf[i] +} +``` + + +### How do we fix node.js core? + +We sent [a PR to node.js core](https://github.com/nodejs/node/pull/4514) (merged as +`semver-major`) which defends against one case: + +```js +var str = 16 +new Buffer(str, 'utf8') +``` + +In this situation, it's implied that the programmer intended the first argument to be a +string, since they passed an encoding as a second argument. Today, node.js will allocate +uninitialized memory in the case of `new Buffer(number, encoding)`, which is probably not +what the programmer intended. + +But this is only a partial solution, since if the programmer does `new Buffer(variable)` +(without an `encoding` parameter) there's no way to know what they intended. If `variable` +is sometimes a number, then uninitialized memory will sometimes be returned. + +### What's the real long-term fix? + +We could deprecate and remove `new Buffer(number)` and use `Buffer.allocUnsafe(number)` when +we need uninitialized memory. But that would break 1000s of packages. + +~~We believe the best solution is to:~~ + +~~1. Change `new Buffer(number)` to return safe, zeroed-out memory~~ + +~~2. Create a new API for creating uninitialized Buffers. We propose: `Buffer.allocUnsafe(number)`~~ + +#### Update + +We now support adding three new APIs: + +- `Buffer.from(value)` - convert from any type to a buffer +- `Buffer.alloc(size)` - create a zero-filled buffer +- `Buffer.allocUnsafe(size)` - create an uninitialized buffer with given size + +This solves the core problem that affected `ws` and `bittorrent-dht` which is +`Buffer(variable)` getting tricked into taking a number argument. + +This way, existing code continues working and the impact on the npm ecosystem will be +minimal. Over time, npm maintainers can migrate performance-critical code to use +`Buffer.allocUnsafe(number)` instead of `new Buffer(number)`. + + +### Conclusion + +We think there's a serious design issue with the `Buffer` API as it exists today. It +promotes insecure software by putting high-risk functionality into a convenient API +with friendly "developer ergonomics". + +This wasn't merely a theoretical exercise because we found the issue in some of the +most popular npm packages. + +Fortunately, there's an easy fix that can be applied today. Use `safe-buffer` in place of +`buffer`. + +```js +var Buffer = require('safe-buffer').Buffer +``` + +Eventually, we hope that node.js core can switch to this new, safer behavior. We believe +the impact on the ecosystem would be minimal since it's not a breaking change. +Well-maintained, popular packages would be updated to use `Buffer.alloc` quickly, while +older, insecure packages would magically become safe from this attack vector. + + +## links + +- [Node.js PR: buffer: throw if both length and enc are passed](https://github.com/nodejs/node/pull/4514) +- [Node Security Project disclosure for `ws`](https://nodesecurity.io/advisories/67) +- [Node Security Project disclosure for`bittorrent-dht`](https://nodesecurity.io/advisories/68) + + +## credit + +The original issues in `bittorrent-dht` +([disclosure](https://nodesecurity.io/advisories/68)) and +`ws` ([disclosure](https://nodesecurity.io/advisories/67)) were discovered by +[Mathias Buus](https://github.com/mafintosh) and +[Feross Aboukhadijeh](http://feross.org/). + +Thanks to [Adam Baldwin](https://github.com/evilpacket) for helping disclose these issues +and for his work running the [Node Security Project](https://nodesecurity.io/). + +Thanks to [John Hiesey](https://github.com/jhiesey) for proofreading this README and +auditing the code. + + +## license + +MIT.

Conversions are still accurate as we make use of BigInt in the conversion process, but in the case of `unsigned long long` we simply cannot represent some possible output values in JavaScript. For example, converting the JavaScript number `-1` to a Web IDL `unsigned long long` is supposed to produce the Web IDL value `18446744073709551615`. Since we are representing our Web IDL values in JavaScript, we can't represent `18446744073709551615`, so we instead the best we could do is `18446744073709551616` as the output. + +To mitigate this, we could return the raw BigInt value from the conversion function, but right now it is not implemented. If your use case requires such precision, [file an issue](https://github.com/jsdom/webidl-conversions/issues/new). + +On the other hand, `long long` conversion is always accurate, since the input value can never be more precise than the output value. + +### A note on `BufferSource` types + +All of the `BufferSource` types will throw when the relevant `ArrayBuffer` has been detached. This technically is not part of the [specified conversion algorithm](https://heycam.github.io/webidl/#es-buffer-source-types), but instead part of the [getting a reference/getting a copy](https://heycam.github.io/webidl/#ref-for-dfn-get-buffer-source-reference%E2%91%A0) algorithms. We've consolidated them here for convenience and ease of implementation, but if there is a need to separate them in the future, please open an issue so we can investigate. + +## Background + +What's actually going on here, conceptually, is pretty weird. Let's try to explain. + +Web IDL, as part of its madness-inducing design, has its own type system. When people write algorithms in web platform specs, they usually operate on Web IDL values, i.e. instances of Web IDL types. For example, if they were specifying the algorithm for our `doStuff` operation above, they would treat `x` as a Web IDL value of [Web IDL type `boolean`](http://heycam.github.io/webidl/#idl-boolean). Crucially, they would _not_ treat `x` as a JavaScript variable whose value is either the JavaScript `true` or `false`. They're instead working in a different type system altogether, with its own rules. + +Separately from its type system, Web IDL defines a ["binding"](http://heycam.github.io/webidl/#ecmascript-binding) of the type system into JavaScript. This contains rules like: when you pass a JavaScript value to the JavaScript method that manifests a given Web IDL operation, how does that get converted into a Web IDL value? For example, a JavaScript `true` passed in the position of a Web IDL `boolean` argument becomes a Web IDL `true`. But, a JavaScript `true` passed in the position of a [Web IDL `unsigned long`](http://heycam.github.io/webidl/#idl-unsigned-long) becomes a Web IDL `1`. And so on. + +Finally, we have the actual implementation code. This is usually C++, although these days [some smart people are using Rust](https://github.com/servo/servo). The implementation, of course, has its own type system. So when they implement the Web IDL algorithms, they don't actually use Web IDL values, since those aren't "real" outside of specs. Instead, implementations apply the Web IDL binding rules in such a way as to convert incoming JavaScript values into C++ values. For example, if code in the browser called `doStuff(true, true)`, then the implementation code would eventually receive a C++ `bool` containing `true` and a C++ `uint32_t` containing `1`. + +The upside of all this is that implementations can abstract all the conversion logic away, letting Web IDL handle it, and focus on implementing the relevant methods in C++ with values of the correct type already provided. That is payoff of Web IDL, in a nutshell. + +And getting to that payoff is the goal of _this_ project—but for JavaScript implementations, instead of C++ ones. That is, this library is designed to make it easier for JavaScript developers to write functions that behave like a given Web IDL operation. So conceptually, the conversion pipeline, which in its general form is JavaScript values ↦ Web IDL values ↦ implementation-language values, in this case becomes JavaScript values ↦ Web IDL values ↦ JavaScript values. And that intermediate step is where all the logic is performed: a JavaScript `true` becomes a Web IDL `1` in an unsigned long context, which then becomes a JavaScript `1`. + +## Don't use this + +Seriously, why would you ever use this? You really shouldn't. Web IDL is … strange, and you shouldn't be emulating its semantics. If you're looking for a generic argument-processing library, you should find one with better rules than those from Web IDL. In general, your JavaScript should not be trying to become more like Web IDL; if anything, we should fix Web IDL to make it more like JavaScript. + +The _only_ people who should use this are those trying to create faithful implementations (or polyfills) of web platform interfaces defined in Web IDL. Its main consumer is the [jsdom](https://github.com/jsdom/jsdom) project. diff --git a/nodejs/node_modules/webidl-conversions/lib/index.js b/nodejs/node_modules/webidl-conversions/lib/index.js new file mode 100644 index 00000000..0229347c --- /dev/null +++ b/nodejs/node_modules/webidl-conversions/lib/index.js @@ -0,0 +1,450 @@ +"use strict"; + +function makeException(ErrorType, message, options) { + if (options.globals) { + ErrorType = options.globals[ErrorType.name]; + } + return new ErrorType(`${options.context ? options.context : "Value"} ${message}.`); +} + +function toNumber(value, options) { + if (typeof value === "bigint") { + throw makeException(TypeError, "is a BigInt which cannot be converted to a number", options); + } + if (!options.globals) { + return Number(value); + } + return options.globals.Number(value); +} + +// Round x to the nearest integer, choosing the even integer if it lies halfway between two. +function evenRound(x) { + // There are four cases for numbers with fractional part being .5: + // + // case | x | floor(x) | round(x) | expected | x <> 0 | x % 1 | x & 1 | example + // 1 | 2n + 0.5 | 2n | 2n + 1 | 2n | > | 0.5 | 0 | 0.5 -> 0 + // 2 | 2n + 1.5 | 2n + 1 | 2n + 2 | 2n + 2 | > | 0.5 | 1 | 1.5 -> 2 + // 3 | -2n - 0.5 | -2n - 1 | -2n | -2n | < | -0.5 | 0 | -0.5 -> 0 + // 4 | -2n - 1.5 | -2n - 2 | -2n - 1 | -2n - 2 | < | -0.5 | 1 | -1.5 -> -2 + // (where n is a non-negative integer) + // + // Branch here for cases 1 and 4 + if ((x > 0 && (x % 1) === +0.5 && (x & 1) === 0) || + (x < 0 && (x % 1) === -0.5 && (x & 1) === 1)) { + return censorNegativeZero(Math.floor(x)); + } + + return censorNegativeZero(Math.round(x)); +} + +function integerPart(n) { + return censorNegativeZero(Math.trunc(n)); +} + +function sign(x) { + return x < 0 ? -1 : 1; +} + +function modulo(x, y) { + // https://tc39.github.io/ecma262/#eqn-modulo + // Note that http://stackoverflow.com/a/4467559/3191 does NOT work for large modulos + const signMightNotMatch = x % y; + if (sign(y) !== sign(signMightNotMatch)) { + return signMightNotMatch + y; + } + return signMightNotMatch; +} + +function censorNegativeZero(x) { + return x === 0 ? 0 : x; +} + +function createIntegerConversion(bitLength, { unsigned }) { + let lowerBound, upperBound; + if (unsigned) { + lowerBound = 0; + upperBound = 2 ** bitLength - 1; + } else { + lowerBound = -(2 ** (bitLength - 1)); + upperBound = 2 ** (bitLength - 1) - 1; + } + + const twoToTheBitLength = 2 ** bitLength; + const twoToOneLessThanTheBitLength = 2 ** (bitLength - 1); + + return (value, options = {}) => { + let x = toNumber(value, options); + x = censorNegativeZero(x); + + if (options.enforceRange) { + if (!Number.isFinite(x)) { + throw makeException(TypeError, "is not a finite number", options); + } + + x = integerPart(x); + + if (x < lowerBound || x > upperBound) { + throw makeException( + TypeError, + `is outside the accepted range of ${lowerBound} to ${upperBound}, inclusive`, + options + ); + } + + return x; + } + + if (!Number.isNaN(x) && options.clamp) { + x = Math.min(Math.max(x, lowerBound), upperBound); + x = evenRound(x); + return x; + } + + if (!Number.isFinite(x) || x === 0) { + return 0; + } + x = integerPart(x); + + // Math.pow(2, 64) is not accurately representable in JavaScript, so try to avoid these per-spec operations if + // possible.

Bug reports and +PRs welcome! + +## Looking for `winston@2.x` documentation? + +Please note that the documentation below is for `winston@3`. +[Read the `winston@2.x` documentation]. + +## Motivation + +`winston` is designed to be a simple and universal logging library with +support for multiple transports. A transport is essentially a storage device +for your logs. Each `winston` logger can have multiple transports (see: +[Transports]) configured at different levels (see: [Logging levels]). For +example, one may want error logs to be stored in a persistent remote location +(like a database), but all logs output to the console or a local file. + +`winston` aims to decouple parts of the logging process to make it more +flexible and extensible. Attention is given to supporting flexibility in log +formatting (see: [Formats]) & levels (see: [Using custom logging levels]), and +ensuring those APIs decoupled from the implementation of transport logging +(i.e. how the logs are stored / indexed, see: [Adding Custom Transports]) to +the API that they exposed to the programmer. + +## Quick Start + +TL;DR? Check out the [quick start example][quick-example] in `./examples/`. +There are a number of other examples in [`./examples/*.js`][examples]. +Don't see an example you think should be there? Submit a pull request +to add it! + +## Usage + +The recommended way to use `winston` is to create your own logger. The +simplest way to do this is using `winston.createLogger`: + +``` js +const winston = require('winston'); + +const logger = winston.createLogger({ + level: 'info', + format: winston.format.json(), + defaultMeta: { service: 'user-service' }, + transports: [ + // + // - Write all logs with importance level of `error` or less to `error.log` + // - Write all logs with importance level of `info` or less to `combined.log` + // + new winston.transports.File({ filename: 'error.log', level: 'error' }), + new winston.transports.File({ filename: 'combined.log' }), + ], +}); + +// +// If we're not in production then log to the `console` with the format: +// `${info.level}: ${info.message} JSON.stringify({ ...rest }) ` +// +if (process.env.NODE_ENV !== 'production') { + logger.add(new winston.transports.Console({ + format: winston.format.simple(), + })); +} +``` + +You may also log directly via the default logger exposed by +`require('winston')`, but this merely intended to be a convenient shared +logger to use throughout your application if you so choose. +Note that the default logger doesn't have any transports by default. +You need add transports by yourself, and leaving the default logger without any +transports may produce a high memory usage issue. + +## Table of contents + +* [Motivation](#motivation) +* [Quick Start](#quick-start) +* [Usage](#usage) +* [Table of Contents](#table-of-contents) +* [Logging](#logging) + * [Creating your logger](#creating-your-own-logger) + * [Streams, `objectMode`, and `info` objects](#streams-objectmode-and-info-objects) +* [Formats] + * [Combining formats](#combining-formats) + * [String interpolation](#string-interpolation) + * [Filtering `info` Objects](#filtering-info-objects) + * [Creating custom formats](#creating-custom-formats) +* [Logging levels] + * [Using logging levels](#using-logging-levels) + * [Using custom logging levels](#using-custom-logging-levels) +* [Transports] + * [Multiple transports of the same type](#multiple-transports-of-the-same-type) + * [Adding Custom Transports](#adding-custom-transports) + * [Common Transport options](#common-transport-options) +* [Exceptions](#exceptions) + * [Handling Uncaught Exceptions with winston](#handling-uncaught-exceptions-with-winston) + * [To Exit or Not to Exit](#to-exit-or-not-to-exit) +* [Rejections](#rejections) + * [Handling Uncaught Promise Rejections with winston](#handling-uncaught-promise-rejections-with-winston) +* [Profiling](#profiling) +* [Streaming Logs](#streaming-logs) +* [Querying Logs](#querying-logs) +* [Further Reading](#further-reading) + * [Using the default logger](#using-the-default-logger) + * [Awaiting logs to be written in `winston`](#awaiting-logs-to-be-written-in-winston) + * [Working with multiple Loggers in `winston`](#working-with-multiple-loggers-in-winston) +* [Installation](#installation) +* [Run Tests](#run-tests) + +## Logging + +Logging levels in `winston` conform to the severity ordering specified by +[RFC5424]: _severity of all levels is assumed to be numerically **ascending** +from most important to least important._ + +``` js +const levels = { + error: 0, + warn: 1, + info: 2, + http: 3, + verbose: 4, + debug: 5, + silly: 6 +}; +``` + +### Creating your own Logger +You get started by creating a logger using `winston.createLogger`: + +``` js +const logger = winston.createLogger({ + transports: [ + new winston.transports.Console(), + new winston.transports.File({ filename: 'combined.log' }) + ] +}); +``` + +A logger accepts the following parameters: + +| Name | Default | Description | +| ------------- | --------------------------- | --------------- | +| `level` | `'info'` | Log only if [`info.level`](#streams-objectmode-and-info-objects) is less than or equal to this level | +| `levels` | `winston.config.npm.levels` | Levels (and colors) representing log priorities | +| `format` | `winston.format.json` | Formatting for `info` messages (see: [Formats]) | +| `transports` | `[]` _(No transports)_ | Set of logging targets for `info` messages | +| `exitOnError` | `true` | If false, handled exceptions will not cause `process.exit` | +| `silent` | `false` | If true, all logs are suppressed | + +The levels provided to `createLogger` will be defined as convenience methods +on the `logger` returned. + +``` js +// +// Logging +// +logger.log({ + level: 'info', + message: 'Hello distributed log files!' +}); + +logger.info('Hello again distributed logs'); +``` + +You can add or remove transports from the `logger` once it has been provided +to you from `winston.createLogger`: + +``` js +const files = new winston.transports.File({ filename: 'combined.log' }); +const console = new winston.transports.Console(); + +logger + .clear() // Remove all transports + .add(console) // Add console transport + .add(files) // Add file transport + .remove(console); // Remove console transport +``` + +You can also wholesale reconfigure a `winston.Logger` instance using the +`configure` method: + +``` js +const logger = winston.createLogger({ + level: 'info', + transports: [ + new winston.transports.Console(), + new winston.transports.File({ filename: 'combined.log' }) + ] +}); + +// +// Replaces the previous transports with those in the +// new configuration wholesale. +// +const DailyRotateFile = require('winston-daily-rotate-file'); +logger.configure({ + level: 'verbose', + transports: [ + new DailyRotateFile(opts) + ] +}); +``` + +### Creating child loggers + +You can create child loggers from existing loggers to pass metadata overrides: + +``` js +const logger = winston.createLogger({ + transports: [ + new winston.transports.Console(), + ] +}); + +const childLogger = logger.child({ requestId: '451' }); +``` +> `.child` is likely to be bugged if you're also extending the `Logger` class, due to some implementation details that make `this` keyword to point to unexpected things. Use with caution. + +### Streams, `objectMode`, and `info` objects + +In `winston`, both `Logger` and `Transport` instances are treated as +[`objectMode`](https://nodejs.org/api/stream.html#stream_object_mode) +streams that accept an `info` object. + +The `info` parameter provided to a given format represents a single log +message. The object itself is mutable. Every `info` must have at least the +`level` and `message` properties: + +``` js +const info = { + level: 'info', // Level of the logging message + message: 'Hey! Log something?' // Descriptive message being logged. +}; +``` + +Properties **besides level and message** are considered as "`meta`". i.e.: + +``` js +const { level, message, ...meta } = info; +``` + +Several of the formats in `logform` itself add additional properties: + +| Property | Format added by | Description | +| ----------- | --------------- | ----------- | +| `splat` | `splat()` | String interpolation splat for `%d %s`-style messages. | +| `timestamp` | `timestamp()` | timestamp the message was received. | +| `label` | `label()` | Custom label associated with each message. | +| `ms` | `ms()` | Number of milliseconds since the previous log message. | + +As a consumer you may add whatever properties you wish – _internal state is +maintained by `Symbol` properties:_ + +- `Symbol.for('level')` _**(READ-ONLY)**:_ equal to `level` property. + **Is treated as immutable by all code.** +- `Symbol.for('message'):` complete string message set by "finalizing formats": + - `json` + - `logstash` + - `printf` + - `prettyPrint` + - `simple` +- `Symbol.for('splat')`: additional string interpolation arguments. _Used + exclusively by `splat()` format._ + +These Symbols are stored in another package: `triple-beam` so that all +consumers of `logform` can have the same Symbol reference. i.e.: + +``` js +const { LEVEL, MESSAGE, SPLAT } = require('triple-beam'); + +console.log(LEVEL === Symbol.for('level')); +// true + +console.log(MESSAGE === Symbol.for('message')); +// true + +console.log(SPLAT === Symbol.for('splat')); +// true +``` + +> **NOTE:** any `{ message }` property in a `meta` object provided will +> automatically be concatenated to any `msg` already provided: For +> example the below will concatenate 'world' onto 'hello': +> +> ``` js +> logger.log('error', 'hello', { message: 'world' }); +> logger.info('hello', { message: 'world' }); +> ``` + +## Formats + +Formats in `winston` can be accessed from `winston.format`. They are +implemented in [`logform`](https://github.com/winstonjs/logform), a separate +module from `winston`. This allows flexibility when writing your own transports +in case you wish to include a default format with your transport. + +In modern versions of `node` template strings are very performant and are the +recommended way for doing most end-user formatting. If you want to bespoke +format your logs, `winston.format.printf` is for you: + +``` js +const { createLogger, format, transports } = require('winston'); +const { combine, timestamp, label, printf } = format; + +const myFormat = printf(({ level, message, label, timestamp }) => { + return `${timestamp} [${label}] ${level}: ${message}`; +}); + +const logger = createLogger({ + format: combine( + label({ label: 'right meow!' }), + timestamp(), + myFormat + ), + transports: [new transports.Console()] +}); +``` + +To see what built-in formats are available and learn more about creating your +own custom logging formats, see [`logform`][logform]. + +### Combining formats + +Any number of formats may be combined into a single format using +`format.combine`. Since `format.combine` takes no `opts`, as a convenience it +returns pre-created instance of the combined format. + +``` js +const { createLogger, format, transports } = require('winston'); +const { combine, timestamp, label, prettyPrint } = format; + +const logger = createLogger({ + format: combine( + label({ label: 'right meow!' }), + timestamp(), + prettyPrint() + ), + transports: [new transports.Console()] +}) + +logger.log({ + level: 'info', + message: 'What time is the testing at?' +}); +// Outputs: +// { level: 'info', +// message: 'What time is the testing at?', +// label: 'right meow!', +// timestamp: '2017-09-30T03:57:26.875Z' } +``` + +### String interpolation + +The `log` method provides the string interpolation using [util.format]. **It +must be enabled using `format.splat()`.** + +Below is an example that defines a format with string interpolation of +messages using `format.splat` and then serializes the entire `info` message +using `format.simple`. + +``` js +const { createLogger, format, transports } = require('winston'); +const logger = createLogger({ + format: format.combine( + format.splat(), + format.simple() + ), + transports: [new transports.Console()] +}); + +// info: test message my string {} +logger.log('info', 'test message %s', 'my string'); + +// info: test message 123 {} +logger.log('info', 'test message %d', 123); + +// info: test message first second {number: 123} +logger.log('info', 'test message %s, %s', 'first', 'second', { number: 123 }); +``` + +### Filtering `info` Objects + +If you wish to filter out a given `info` Object completely when logging then +simply return a falsey value. + +``` js +const { createLogger, format, transports } = require('winston'); + +// Ignore log messages if they have { private: true } +const ignorePrivate = format((info, opts) => { + if (info.private) { return false; } + return info; +}); + +const logger = createLogger({ + format: format.combine( + ignorePrivate(), + format.json() + ), + transports: [new transports.Console()] +}); + +// Outputs: {"level":"error","message":"Public error to share"} +logger.log({ + level: 'error', + message: 'Public error to share' +}); + +// Messages with { private: true } will not be written when logged. +logger.log({ + private: true, + level: 'error', + message: 'This is super secret - hide it.' +}); +``` + +Use of `format.combine` will respect any falsey values return and stop +evaluation of later formats in the series. For example: + +``` js +const { format } = require('winston'); +const { combine, timestamp, label } = format; + +const willNeverThrow = format.combine( + format(info => { return false })(), // Ignores everything + format(info => { throw new Error('Never reached') })() +); +``` + +### Creating custom formats + +Formats are prototypal objects (i.e. class instances) that define a single +method: `transform(info, opts)` and return the mutated `info`: + +- `info`: an object representing the log message. +- `opts`: setting specific to the current instance of the format. + +They are expected to return one of two things: + +- **An `info` Object** representing the modified `info` argument. Object +references need not be preserved if immutability is preferred. All current +built-in formats consider `info` mutable, but [immutablejs] is being +considered for future releases. +- **A falsey value** indicating that the `info` argument should be ignored by the +caller. (See: [Filtering `info` Objects](#filtering-info-objects)) below. + +`winston.format` is designed to be as simple as possible. To define a new +format, simply pass it a `transform(info, opts)` function to get a new +`Format`. + +The named `Format` returned can be used to create as many copies of the given +`Format` as desired: + +``` js +const { format } = require('winston'); + +const volume = format((info, opts) => { + if (opts.yell) { + info.message = info.message.toUpperCase(); + } else if (opts.whisper) { + info.message = info.message.toLowerCase(); + } + + return info; +}); + +// `volume` is now a function that returns instances of the format. +const scream = volume({ yell: true }); +console.dir(scream.transform({ + level: 'info', + message: `sorry for making you YELL in your head!` +}, scream.options)); +// { +// level: 'info' +// message: 'SORRY FOR MAKING YOU YELL IN YOUR HEAD!' +// } + +// `volume` can be used multiple times to create different formats. +const whisper = volume({ whisper: true }); +console.dir(whisper.transform({ + level: 'info', + message: `WHY ARE THEY MAKING US YELL SO MUCH!` +}, whisper.options)); +// { +// level: 'info' +// message: 'why are they making us yell so much!' +// } +``` + +## Logging Levels + +Logging levels in `winston` conform to the severity ordering specified by +[RFC5424]: _severity of all levels is assumed to be numerically **ascending** +from most important to least important._ + +Each `level` is given a specific integer priority. The higher the priority the +more important the message is considered to be, and the lower the +corresponding integer priority. For example, as specified exactly in RFC5424 +the `syslog` levels are prioritized from 0 to 7 (highest to lowest). + +```js +{ + emerg: 0, + alert: 1, + crit: 2, + error: 3, + warning: 4, + notice: 5, + info: 6, + debug: 7 +} +``` + +Similarly, `npm` logging levels are prioritized from 0 to 6 (highest to +lowest): + +``` js +{ + error: 0, + warn: 1, + info: 2, + http: 3, + verbose: 4, + debug: 5, + silly: 6 +} +``` + +If you do not explicitly define the levels that `winston` should use, the +`npm` levels above will be used. + +### Using Logging Levels + +Setting the level for your logging message can be accomplished in one of two +ways. You can pass a string representing the logging level to the log() method +or use the level specified methods defined on every winston Logger. + +``` js +// +// Any logger instance +// +logger.log('silly', "127.0.0.1 - there's no place like home"); +logger.log('debug', "127.0.0.1 - there's no place like home"); +logger.log('verbose', "127.0.0.1 - there's no place like home"); +logger.log('info', "127.0.0.1 - there's no place like home"); +logger.log('warn', "127.0.0.1 - there's no place like home"); +logger.log('error', "127.0.0.1 - there's no place like home"); +logger.info("127.0.0.1 - there's no place like home"); +logger.warn("127.0.0.1 - there's no place like home"); +logger.error("127.0.0.1 - there's no place like home"); + +// +// Default logger +// +winston.log('info', "127.0.0.1 - there's no place like home"); +winston.info("127.0.0.1 - there's no place like home"); +``` + +`winston` allows you to define a `level` property on each transport which +specifies the **maximum** level of messages that a transport should log. For +example, using the `syslog` levels you could log only `error` messages to the +console and everything `info` and below to a file (which includes `error` +messages): + +``` js +const logger = winston.createLogger({ + levels: winston.config.syslog.levels, + transports: [ + new winston.transports.Console({ level: 'error' }), + new winston.transports.File({ + filename: 'combined.log', + level: 'info' + }) + ] +}); +``` + +You may also dynamically change the log level of a transport: + +``` js +const transports = { + console: new winston.transports.Console({ level: 'warn' }), + file: new winston.transports.File({ filename: 'combined.log', level: 'error' }) +}; + +const logger = winston.createLogger({ + transports: [ + transports.console, + transports.file + ] +}); + +logger.info('Will not be logged in either transport!'); +transports.console.level = 'info'; +transports.file.level = 'info'; +logger.info('Will be logged in both transports!'); +``` + +`winston` supports customizable logging levels, defaulting to npm style +logging levels. Levels must be specified at the time of creating your logger. + +### Using Custom Logging Levels + +In addition to the predefined `npm`, `syslog`, and `cli` levels available in +`winston`, you can also choose to define your own: + +``` js +const myCustomLevels = { + levels: { + foo: 0, + bar: 1, + baz: 2, + foobar: 3 + }, + colors: { + foo: 'blue', + bar: 'green', + baz: 'yellow', + foobar: 'red' + } +}; + +const customLevelLogger = winston.createLogger({ + levels: myCustomLevels.levels +}); + +customLevelLogger.foobar('some foobar level-ed message'); +``` + +Although there is slight repetition in this data structure, it enables simple +encapsulation if you do not want to have colors. If you do wish to have +colors, in addition to passing the levels to the Logger itself, you must make +winston aware of them: + +``` js +winston.addColors(myCustomLevels.colors); +``` + +This enables loggers using the `colorize` formatter to appropriately color and style +the output of custom levels. + +Additionally, you can also change background color and font style. +For example, +``` js +baz: 'italic yellow', +foobar: 'bold red cyanBG' +``` + +Possible options are below. + +* Font styles: `bold`, `dim`, `italic`, `underline`, `inverse`, `hidden`, + `strikethrough`. + +* Font foreground colors: `black`, `red`, `green`, `yellow`, `blue`, `magenta`, + `cyan`, `white`, `gray`, `grey`. + +* Background colors: `blackBG`, `redBG`, `greenBG`, `yellowBG`, `blueBG` + `magentaBG`, `cyanBG`, `whiteBG` + +### Colorizing Standard logging levels + +To colorize the standard logging level add +```js +winston.format.combine( + winston.format.colorize(), + winston.format.simple() +); +``` +where `winston.format.simple()` is whatever other formatter you want to use. The `colorize` formatter must come before any formatters adding text you wish to color. + +### Colorizing full log line when json formatting logs + +To colorize the full log line with the json formatter you can apply the following + +```js +winston.format.combine( + winston.format.json(), + winston.format.colorize({ all }) +); +``` + +## Transports + +There are several [core transports] included in `winston`, which leverage the +built-in networking and file I/O offered by Node.js core. In addition, there +are [additional transports] written by members of the community. + +## Multiple transports of the same type + +It is possible to use multiple transports of the same type e.g. +`winston.transports.File` when you construct the transport. + +``` js +const logger = winston.createLogger({ + transports: [ + new winston.transports.File({ + filename: 'combined.log', + level: 'info' + }), + new winston.transports.File({ + filename: 'errors.log', + level: 'error' + }) + ] +}); +``` + +If you later want to remove one of these transports you can do so by using the +transport itself. e.g.: + +``` js +const combinedLogs = logger.transports.find(transport => { + return transport.filename === 'combined.log' +}); + +logger.remove(combinedLogs); +``` + +## Adding Custom Transports + +Adding a custom transport is easy. All you need to do is accept any options +you need, implement a log() method, and consume it with `winston`. + +``` js +const Transport = require('winston-transport'); +const util = require('util'); + +// +// Inherit from `winston-transport` so you can take advantage +// of the base functionality and `.exceptions.handle()`. +// +module.exports = class YourCustomTransport extends Transport { + constructor(opts) { + super(opts); + // + // Consume any custom options here. e.g.: + // - Connection information for databases + // - Authentication information for APIs (e.g. loggly, papertrail, + // logentries, etc.). + // + } + + log(info, callback) { + setImmediate(() => { + this.emit('logged', info); + }); + + // Perform the writing to the remote service + callback(); + } +}; +``` + +## Common Transport options + +As every transport inherits from [winston-transport], it's possible to set +a custom format and a custom log level on each transport separately: + +``` js +const logger = winston.createLogger({ + transports: [ + new winston.transports.File({ + filename: 'error.log', + level: 'error', + format: winston.format.json() + }), + new winston.transports.Http({ + level: 'warn', + format: winston.format.json() + }), + new winston.transports.Console({ + level: 'info', + format: winston.format.combine( + winston.format.colorize(), + winston.format.simple() + ) + }) + ] +}); +``` + +## Exceptions + +### Handling Uncaught Exceptions with winston + +With `winston`, it is possible to catch and log `uncaughtException` events +from your process. With your own logger instance you can enable this behavior +when it's created or later on in your applications lifecycle: + +``` js +const { createLogger, transports } = require('winston'); + +// Enable exception handling when you create your logger. +const logger = createLogger({ + transports: [ + new transports.File({ filename: 'combined.log' }) + ], + exceptionHandlers: [ + new transports.File({ filename: 'exceptions.log' }) + ] +}); + +// Or enable it later on by adding a transport or using `.exceptions.handle` +const logger = createLogger({ + transports: [ + new transports.File({ filename: 'combined.log' }) + ] +}); + +// Call exceptions.handle with a transport to handle exceptions +logger.exceptions.handle( + new transports.File({ filename: 'exceptions.log' }) +); +``` + +If you want to use this feature with the default logger, simply call +`.exceptions.handle()` with a transport instance. + +``` js +// +// You can add a separate exception logger by passing it to `.exceptions.handle` +// +winston.exceptions.handle( + new winston.transports.File({ filename: 'path/to/exceptions.log' }) +); + +// +// Alternatively you can set `handleExceptions` to true when adding transports +// to winston. +// +winston.add(new winston.transports.File({ + filename: 'path/to/combined.log', + handleExceptions: true +})); +``` + +### To Exit or Not to Exit + +By default, winston will exit after logging an uncaughtException. If this is +not the behavior you want, set `exitOnError = false` + +``` js +const logger = winston.createLogger({ exitOnError: false }); + +// +// or, like this: +// +logger.exitOnError = false; +``` + +When working with custom logger instances, you can pass in separate transports +to the `exceptionHandlers` property or set `handleExceptions` on any +transport. + +##### Example 1 + +``` js +const logger = winston.createLogger({ + transports: [ + new winston.transports.File({ filename: 'path/to/combined.log' }) + ], + exceptionHandlers: [ + new winston.transports.File({ filename: 'path/to/exceptions.log' }) + ] +}); +``` + +##### Example 2 + +``` js +const logger = winston.createLogger({ + transports: [ + new winston.transports.Console({ + handleExceptions: true + }) + ], + exitOnError: false +}); +``` + +The `exitOnError` option can also be a function to prevent exit on only +certain types of errors: + +``` js +function ignoreEpipe(err) { + return err.code !== 'EPIPE'; +} + +const logger = winston.createLogger({ exitOnError: ignoreEpipe }); + +// +// or, like this: +// +logger.exitOnError = ignoreEpipe; +``` + +## Rejections + +### Handling Uncaught Promise Rejections with winston + +With `winston`, it is possible to catch and log `unhandledRejection` events +from your process. With your own logger instance you can enable this behavior +when it's created or later on in your applications lifecycle: + +``` js +const { createLogger, transports } = require('winston'); + +// Enable rejection handling when you create your logger. +const logger = createLogger({ + transports: [ + new transports.File({ filename: 'combined.log' }) + ], + rejectionHandlers: [ + new transports.File({ filename: 'rejections.log' }) + ] +}); + +// Or enable it later on by adding a transport or using `.rejections.handle` +const logger = createLogger({ + transports: [ + new transports.File({ filename: 'combined.log' }) + ] +}); + +// Call rejections.handle with a transport to handle rejections +logger.rejections.handle( + new transports.File({ filename: 'rejections.log' }) +); +``` + +If you want to use this feature with the default logger, simply call +`.rejections.handle()` with a transport instance. + +``` js +// +// You can add a separate rejection logger by passing it to `.rejections.handle` +// +winston.rejections.handle( + new winston.transports.File({ filename: 'path/to/rejections.log' }) +); + +// +// Alternatively you can set `handleRejections` to true when adding transports +// to winston. +// +winston.add(new winston.transports.File({ + filename: 'path/to/combined.log', + handleRejections: true +})); +``` + +## Profiling + +In addition to logging messages and metadata, `winston` also has a simple +profiling mechanism implemented for any logger: + +``` js +// +// Start profile of 'test' +// +logger.profile('test'); + +setTimeout(function () { + // + // Stop profile of 'test'. Logging will now take place: + // '17 Jan 21:00:00 - info: test duration=1000ms' + // + logger.profile('test'); +}, 1000); +``` + +Also you can start a timer and keep a reference that you can call `.done()` +on: + +``` js + // Returns an object corresponding to a specific timing. When done + // is called the timer will finish and log the duration. e.g.: + // + const profiler = logger.startTimer(); + setTimeout(function () { + profiler.done({ message: 'Logging message' }); + }, 1000); +``` + +All profile messages are set to 'info' level by default, and both message and +metadata are optional. For individual profile messages, you can override the default log level by supplying a metadata object with a `level` property: + +```js +logger.profile('test', { level: 'debug' }); +``` + +## Querying Logs + +`winston` supports querying of logs with Loggly-like options. [See Loggly +Search API](https://www.loggly.com/docs/api-retrieving-data/). Specifically: +`File`, `Couchdb`, `Redis`, `Loggly`, `Nssocket`, and `Http`. + +``` js +const options = { + from: new Date() - (24 * 60 * 60 * 1000), + until: new Date(), + limit: 10, + start: 0, + order: 'desc', + fields: ['message'] +}; + +// +// Find items logged between today and yesterday. +// +logger.query(options, function (err, results) { + if (err) { + /* TODO: handle me */ + throw err; + } + + console.log(results); +}); +``` + +## Streaming Logs +Streaming allows you to stream your logs back from your chosen transport. + +``` js +// +// Start at the end. +// +winston.stream({ start: -1 }).on('log', function(log) { + console.log(log); +}); +``` + +## Further Reading + +### Using the Default Logger + +The default logger is accessible through the `winston` module directly. Any +method that you could call on an instance of a logger is available on the +default logger: + +``` js +const winston = require('winston'); + +winston.log('info', 'Hello distributed log files!'); +winston.info('Hello again distributed logs'); + +winston.level = 'debug'; +winston.log('debug', 'Now my debug messages are written to console!'); +``` + +By default, no transports are set on the default logger. You must +add or remove transports via the `add()` and `remove()` methods: + +``` js +const files = new winston.transports.File({ filename: 'combined.log' }); +const console = new winston.transports.Console(); + +winston.add(console); +winston.add(files); +winston.remove(console); +``` + +Or do it with one call to configure(): + +``` js +winston.configure({ + transports: [ + new winston.transports.File({ filename: 'somefile.log' }) + ] +}); +``` + +For more documentation about working with each individual transport supported +by `winston` see the [`winston` Transports](docs/transports.md) document. + +### Awaiting logs to be written in `winston` + +Often it is useful to wait for your logs to be written before exiting the +process. Each instance of `winston.Logger` is also a [Node.js stream]. A +`finish` event will be raised when all logs have flushed to all transports +after the stream has been ended. + +``` js +const transport = new winston.transports.Console(); +const logger = winston.createLogger({ + transports: [transport] +}); + +logger.on('finish', function (info) { + // All `info` log messages has now been logged +}); + +logger.info('CHILL WINSTON!', { seriously: true }); +logger.end(); +``` + +It is also worth mentioning that the logger also emits an 'error' event +if an error occurs within the logger itself which +you should handle or suppress if you don't want unhandled exceptions: + +``` js +// +// Handle errors originating in the logger itself +// +logger.on('error', function (err) { /* Do Something */ }); +``` + +### Working with multiple Loggers in winston + +Often in larger, more complex, applications it is necessary to have multiple +logger instances with different settings. Each logger is responsible for a +different feature area (or category). This is exposed in `winston` in two +ways: through `winston.loggers` and instances of `winston.Container`. In fact, +`winston.loggers` is just a predefined instance of `winston.Container`: + +``` js +const winston = require('winston'); +const { format } = winston; +const { combine, label, json } = format; + +// +// Configure the logger for `category1` +// +winston.loggers.add('category1', { + format: combine( + label({ label: 'category one' }), + json() + ), + transports: [ + new winston.transports.Console({ level: 'silly' }), + new winston.transports.File({ filename: 'somefile.log' }) + ] +}); + +// +// Configure the logger for `category2` +// +winston.loggers.add('category2', { + format: combine( + label({ label: 'category two' }), + json() + ), + transports: [ + new winston.transports.Http({ host: 'localhost', port:8080 }) + ] +}); +``` + +Now that your loggers are setup, you can require winston _in any file in your +application_ and access these pre-configured loggers: + +``` js +const winston = require('winston'); + +// +// Grab your preconfigured loggers +// +const category1 = winston.loggers.get('category1'); +const category2 = winston.loggers.get('category2'); + +category1.info('logging to file and console transports'); +category2.info('logging to http transport'); +``` + +If you prefer to manage the `Container` yourself, you can simply instantiate one: + +``` js +const winston = require('winston'); +const { format } = winston; +const { combine, label, json } = format; + +const container = new winston.Container(); + +container.add('category1', { + format: combine( + label({ label: 'category one' }), + json() + ), + transports: [ + new winston.transports.Console({ level: 'silly' }), + new winston.transports.File({ filename: 'somefile.log' }) + ] +}); + +const category1 = container.get('category1'); +category1.info('logging to file and console transports'); +``` + +## Installation + +``` bash +npm install winston +``` + +``` bash +yarn add winston +``` + +## Run Tests + +All of the winston tests are written with [`mocha`][mocha], [`nyc`][nyc], and +[`assume`][assume]. They can be run with `npm`. + +``` bash +npm test +``` + +#### Author: [Charlie Robbins] +#### Contributors: [Jarrett Cruger], [David Hyde], [Chris Alderson] + +[Transports]: #transports +[Logging levels]: #logging-levels +[Formats]: #formats +[Using custom logging levels]: #using-custom-logging-levels +[Adding Custom Transports]: #adding-custom-transports +[core transports]: docs/transports.md#winston-core +[additional transports]: docs/transports.md#additional-transports + +[RFC5424]: https://tools.ietf.org/html/rfc5424 +[util.format]: https://nodejs.org/dist/latest/docs/api/util.html#util_util_format_format_args +[mocha]: https://mochajs.org +[nyc]: https://github.com/istanbuljs/nyc +[assume]: https://github.com/bigpipe/assume +[logform]: https://github.com/winstonjs/logform#readme +[winston-transport]: https://github.com/winstonjs/winston-transport + +[Read the `winston@2.x` documentation]: https://github.com/winstonjs/winston/tree/2.x + +[quick-example]: https://github.com/winstonjs/winston/blob/master/examples/quick-start.js +[examples]: https://github.com/winstonjs/winston/tree/master/examples + +[Charlie Robbins]: http://github.com/indexzero +[Jarrett Cruger]: https://github.com/jcrugzz +[David Hyde]: https://github.com/dabh +[Chris Alderson]: https://github.com/chrisalderson diff --git a/nodejs/node_modules/winston/dist/winston.js b/nodejs/node_modules/winston/dist/winston.js new file mode 100644 index 00000000..45ed8693 --- /dev/null +++ b/nodejs/node_modules/winston/dist/winston.js @@ -0,0 +1,171 @@ +/** + * winston.js: Top-level include defining Winston. + * + * (C) 2010 Charlie Robbins + * MIT LICENCE + */ + +'use strict'; + +var logform = require('logform'); +var _require = require('./winston/common'), + warn = _require.warn; + +/** + * Expose version.

It adds a significant overhead in terms of performance and memory +consumption so we suggest to enable it only if it is really needed. + +Note that Node.js has a variety of issues with high-performance compression, +where increased concurrency, especially on Linux, can lead to [catastrophic +memory fragmentation][node-zlib-bug] and slow performance. If you intend to use +permessage-deflate in production, it is worthwhile to set up a test +representative of your workload and ensure Node.js/zlib will handle it with +acceptable performance and memory usage. + +Tuning of permessage-deflate can be done via the options defined below. You can +also use `zlibDeflateOptions` and `zlibInflateOptions`, which is passed directly +into the creation of [raw deflate/inflate streams][node-zlib-deflaterawdocs]. + +See [the docs][ws-server-options] for more options. + +```js +import WebSocket, { WebSocketServer } from 'ws'; + +const wss = new WebSocketServer({ + port: 8080, + perMessageDeflate: { + zlibDeflateOptions: { + // See zlib defaults. + chunkSize: 1024, + memLevel: 7, + level: 3 + }, + zlibInflateOptions: { + chunkSize: 10 * 1024 + }, + // Other options settable: + clientNoContextTakeover: true, // Defaults to negotiated value. + serverNoContextTakeover: true, // Defaults to negotiated value. + serverMaxWindowBits: 10, // Defaults to negotiated value. + // Below options specified as default values. + concurrencyLimit: 10, // Limits zlib concurrency for perf. + threshold: 1024 // Size (in bytes) below which messages + // should not be compressed if context takeover is disabled. + } +}); +``` + +The client will only use the extension if it is supported and enabled on the +server. To always disable the extension on the client set the +`perMessageDeflate` option to `false`. + +```js +import WebSocket from 'ws'; + +const ws = new WebSocket('ws://www.host.com/path', { + perMessageDeflate: false +}); +``` + +## Usage examples + +### Sending and receiving text data + +```js +import WebSocket from 'ws'; + +const ws = new WebSocket('ws://www.host.com/path'); + +ws.on('error', console.error); + +ws.on('open', function open() { + ws.send('something'); +}); + +ws.on('message', function message(data) { + console.log('received: %s', data); +}); +``` + +### Sending binary data + +```js +import WebSocket from 'ws'; + +const ws = new WebSocket('ws://www.host.com/path'); + +ws.on('error', console.error); + +ws.on('open', function open() { + const array = new Float32Array(5); + + for (var i = 0; i < array.length; ++i) { + array[i] = i / 2; + } + + ws.send(array); +}); +``` + +### Simple server + +```js +import { WebSocketServer } from 'ws'; + +const wss = new WebSocketServer({ port: 8080 }); + +wss.on('connection', function connection(ws) { + ws.on('error', console.error); + + ws.on('message', function message(data) { + console.log('received: %s', data); + }); + + ws.send('something'); +}); +``` + +### External HTTP/S server + +```js +import { createServer } from 'https'; +import { readFileSync } from 'fs'; +import { WebSocketServer } from 'ws'; + +const server = createServer({ + cert: readFileSync('/path/to/cert.pem'), + key: readFileSync('/path/to/key.pem') +}); +const wss = new WebSocketServer({ server }); + +wss.on('connection', function connection(ws) { + ws.on('error', console.error); + + ws.on('message', function message(data) { + console.log('received: %s', data); + }); + + ws.send('something'); +}); + +server.listen(8080); +``` + +### Multiple servers sharing a single HTTP/S server + +```js +import { createServer } from 'http'; +import { parse } from 'url'; +import { WebSocketServer } from 'ws'; + +const server = createServer(); +const wss1 = new WebSocketServer({ noServer: true }); +const wss2 = new WebSocketServer({ noServer: true }); + +wss1.on('connection', function connection(ws) { + ws.on('error', console.error); + + // ... +}); + +wss2.on('connection', function connection(ws) { + ws.on('error', console.error); + + // ... +}); + +server.on('upgrade', function upgrade(request, socket, head) { + const { pathname } = parse(request.url); + + if (pathname === '/foo') { + wss1.handleUpgrade(request, socket, head, function done(ws) { + wss1.emit('connection', ws, request); + }); + } else if (pathname === '/bar') { + wss2.handleUpgrade(request, socket, head, function done(ws) { + wss2.emit('connection', ws, request); + }); + } else { + socket.destroy(); + } +}); + +server.listen(8080); +``` + +### Client authentication + +```js +import { createServer } from 'http'; +import { WebSocketServer } from 'ws'; + +function onSocketError(err) { + console.error(err); +} + +const server = createServer(); +const wss = new WebSocketServer({ noServer: true }); + +wss.on('connection', function connection(ws, request, client) { + ws.on('error', console.error); + + ws.on('message', function message(data) { + console.log(`Received message ${data} from user ${client}`); + }); +}); + +server.on('upgrade', function upgrade(request, socket, head) { + socket.on('error', onSocketError); + + // This function is not defined on purpose.
