unchanged

A tiny (~2.1kB minified+gzipped), fast, unopinionated handler for updating JS objects and arrays immutably.

Supports nested key paths via path arrays or dotty syntax, and all methods are curriable (with placeholder support) for composability. Can be a drop-in replacement for the lodash/fp methods get, set, merge, and omit with a 90% smaller footprint.

const object: unchanged.Unchangeable = {
  foo: "foo",
  bar: [
    {
      baz: "quz"
    }
  ]
};

// handle standard properties
const foo = get("foo", object);

// or nested properties
const baz = set("bar[0].baz", "not quz", object);

// all methods are curriable
const removeBaz = remove("bar[0].baz");
const sansBaz = removeBaz(object);

NOTE: There is no default export, so if you want to import all methods to a single namespace you should use the import * syntax:

import * as uc from "unchanged";

Types

This library is both written in, and provided with, types by TypeScript. The internal types used for specific parameters are scoped to the unchanged namespace.

// the path used to compute nested locations
type Path = (number | string)[] | number | string;
// the callback used in transform methods
type WithHandler = (value: any, ...extraParams: any[]) => any;
// the generic object that is computed upon, either an array or object
interface Unchangeable {
  [key: string]: any;
  [index: number]: any;
}

Notice in the Unchangeable interface, there is no reference to symbols. That is because to date, TypeScript does not support Symbols as an index type. If you need to use symbols as object keys, the best workaround I've found is to typecast when it complains:

const symbolKey = (Symbol("key") as unknown) as string;

const object: { [symbolKey]: string } = {
  [symbolKey]: "bar"
};

If there is a better alternative for having dynamic Symbol indices, let me know! Happy to accept any PRs from those more experienced in TypeScript than myself.

Standard methods

get

function get(path: unchanged.Path, object: unchanged.Unchangeable): any;

Get the value at the path requested on the object passed.

const object: unchanged.Unchangeable = {
  foo: [
    {
      bar: "baz"
    }
  ]
};

console.log(get("foo[0].bar", object)); // baz
console.log(get(["foo", 0, "bar"], object)); // baz

getOr

function getOr(
  fallbackValue: any,
  path: unchanged.Path,
  object: unchanged.Unchangeable
): any;

Get the value at the path requested on the object passed, with a fallback value if that path does not exist.

const object: unchanged.Unchangeable = {
  foo: [
    {
      bar: "baz"
    }
  ]
};

console.log(getOr("blah", "foo[0].bar", object)); // baz
console.log(getOr("blah", ["foo", 0, "bar"], object)); // baz
console.log(getOr("blah", "foo[0].nonexistent", object)); // blah

set

function set(
  path: unchanged.Path,
  value: any,
  object: unchanged.Unchangeable
): unchanged.Unchangeable;

Returns a new object based on the object passed, with the value assigned to the final key on the path specified.

const object: unchanged.Unchangeable = {
  foo: [
    {
      bar: "baz"
    }
  ]
};

console.log(set("foo[0].bar", "quz", object)); // {foo: [{bar: 'quz'}]}
console.log(set(["foo", 0, "bar"], "quz", object)); // {foo: [{bar: 'quz'}]}

remove

function remove(
  path: unchanged.Path,
  object: unchanged.Unchangeable
): unchanged.Unchangeable;

Returns a new object based on the object passed, with the final key on the path removed if it exists.

const object: unchanged.Unchangeable = {
  foo: [
    {
      bar: "baz"
    }
  ]
};

console.log(remove("foo[0].bar", object)); // {foo: [{}]}
console.log(remove(["foo", 0, "bar"], object)); // {foo: [{}]}

has

function has(path: unchanged.Path, object: unchanged.Unchangeable): boolean;

Returns true if the object has the path provided, false otherwise.

const object: unchanged.Unchangeable = {
  foo: [
    {
      bar: "baz"
    }
  ]
};

console.log(has("foo[0].bar", object)); // true
console.log(has(["foo", 0, "bar"], object)); // true
console.log(has("bar", object)); // false

is

function is(
  path: unchanged.Path,
  value: any,
  object: unchanged.Unchangeable
): boolean;

Returns true if the value at the path in object is equal to value based on SameValueZero equality, false otherwise.

const object: unchanged.Unchangeable = {
  foo: [
    {
      bar: "baz"
    }
  ]
};

console.log(is("foo[0].bar", "baz", object)); // true
console.log(is(["foo", 0, "bar"], "baz", object)); // true
console.log(is("foo[0].bar", "quz", object)); // false

not

function not(
  path: unchanged.Path,
  value: any,
  object: unchanged.Unchangeable
): boolean;

Returns false if the value at the path in object is equal to value based on SameValueZero equality, true otherwise.

const object: unchanged.Unchangeable = {
  foo: [
    {
      bar: "baz"
    }
  ]
};

console.log(not("foo[0].bar", "baz", object)); // false
console.log(not(["foo", 0, "bar"], "baz", object)); // false
console.log(not("foo[0].bar", "quz", object)); // true

add

function add(
  path: unchanged.Path,
  value: any,
  object: unchanged.Unchangeable
): unchanged.Unchangeable;

Returns a new object based on the object passed, with the value added at the path specified. This can have different behavior depending on whether the item is an object or an array; objects will simply add / set the key provided, whereas arrays will add a new value to the end.

const object: unchanged.Unchangeable = {
  foo: [
    {
      bar: 'baz'
    }
  ]
};

// object
console.log(add('foo', 'added value' object)); // {foo: [{bar: 'baz'}, 'added value']}
console.log(add(['foo'], 'added value', object)); // {foo: [{bar: 'baz'}, 'added value']}

// array
console.log(add('foo[0].quz', 'added value' object)); // {foo: [{bar: 'baz', quz: 'added value'}]}
console.log(add(['foo', 0, 'quz'], 'added value', object)); // {foo: [{bar: 'baz', quz: 'added value'}]}

Notice that the Object usage is idential to the set method, where a key needs to be specified for assignment. In the case of an Array, however, the value is pushed to the array at that key.

NOTE: If you want to add an item to a top-level array, pass null as the key:

const object = ["foo"];

console.log(add(null, "bar", object)); // ['foo', 'bar']

merge

function merge(
  path: unchanged.Path,
  value: unchanged.Unchangeable,
  object: unchanged.Unchangeable
): unchanged.Unchangeable;

Returns a new object that is a deep merge of value into object at the path specified. If you want to perform a shallow merge, see assign.

const object1: unchanged.Unchangeable = {
  foo: "bar",
  baz: {
    one: "value1",
    deeply: {
      nested: "value",
      untouched: true
    },
    two: "value2"
  }
};
const object2: unchanged.Unchangeable = {
  one: "new value",
  deeply: {
    nested: "other value"
  },
  three: "value3"
};

console.log(merge("baz", object2, object1));
/*
{
  foo: 'bar',
  baz: {
    one: 'new value',
    deeply: {
      nested: 'other value',
      untouched: true,
    },
    two: 'value2',
    three: 'value3
  }
}

NOTE: If you want to merge the entirety of both objects, pass null as the key:

console.log(merge(null, object2, object1));
/*
{
  foo: "bar",
  baz: {
    one: "value1",
    deeply: {
      nested: "value",
      untouched: true
    },
    two: "value2"
  },
  one: "new value",
  deeply: {
    nested: "other value"
  },
  three: "value3"
}
*/

assign

function assign(
  path: unchanged.Path,
  value: unchanged.Unchangeable,
  object: unchanged.Unchangeable
): unchanged.Unchangeable;

Returns a new object that is a shallow merge of value into object at the path specified. If you want to perform a deep merge, see merge.

const object1: unchanged.Unchangeable = {
  foo: "bar",
  baz: {
    one: "value1",
    deeply: {
      nested: "value",
      untouched: true
    },
    two: "value2"
  }
};
const object2: unchanged.Unchangeable = {
  one: "new value",
  deeply: {
    nested: "other value"
  },
  three: "value3"
};

console.log(assign("baz", object2, object1));
/*
{
  foo: 'bar',
  baz: {
    one: 'new value',
    deeply: {
      nested: 'other value',
    },
    two: 'value2',
    three: 'value3
  }
}

NOTE: If you want to assign the entirety of both objects, pass null as the key:

console.log(assign(null, object2, object1));
/*
{
  foo: "bar",
  baz: {
    one: "value1",
    deeply: {
      nested: "value",
      untouched: true
    },
    two: "value2"
  },
  one: "new value",
  deeply: {
    nested: "other value"
  },
  three: "value3"
}
*/

call

function call(
  path: unchanged.Path,
  parameters: any[],
  object: unchanged.Unchangeable,
  context?: any = object
): any;

Call the method at the path requested on the object passed, and return what it's call returns.

const object: unchanged.Unchangeable = {
  foo: [
    {
      bar(a, b) {
        return a + b;
      }
    }
  ]
};

console.log(call("foo[0].bar", [1, 2], object)); // 3
console.log(call(["foo", 0, "bar"], [1, 2], object)); // 3

You can also provide an optional fourth parameter of context, which will be the this value in the method call. This will default to the object itself.

const object: unchanged.Unchangeable = {
  calculate: true,
  foo: [
    {
      bar(a, b) {
        return this.calculate ? a + b : 0;
      }
    }
  ]
};

console.log(call("foo[0].bar", [1, 2], object)); // 3
console.log(call("foo[0].bar", [1, 2], object, {})); // 0

NOTE: Because context is optional, it cannot be independently curried; you must apply it in the call when the object is passed.

Transform methods

Each standard method has it's own related With method, which accepts a callback fn as the first curried parameter. In most cases this callback serves as a transformer for the value retrieved, set, merged, etc.; the exception is removeWith, where the callback serves as a validator as to whether to remove or not.

The signature of all callbacks is the withHandler specified in Types. Because extraParams are optional parameters, they cannot be independently curried; you must apply them in the call when the object is passed.

getWith

function getWith(
  fn: unchanged.withHandler,
  path: unchanged.Path,
  object: unchanged.Unchangeable,
  ...extraParams?: any[]
): any;

Get the return value of fn based on the value at the path requested on the object passed. fn is called with the current value at the path as the first parameter, and any additional parameters passed as extraParams following that.

const object: unchanged.Unchangeable = {
  foo: [
    {
      bar: "baz"
    }
  ]
};
const fn: unchanged.withHandler = (value: any, nullValue: any): any =>
  currentValue === nullValue ? null : currentValue;

console.log(getWith(fn, "foo[0].bar", object)); // 'baz'
console.log(getWith(fn, "foo[0].bar", object, "baz")); // null
console.log(getWith(fn, ["foo", 0, "bar"], object)); // 'baz'
console.log(getWith(fn, ["foo", 0, "bar"], object, "baz")); // null

getWithOr

function getWithOr(
  fn: unchanged.withHandler,
  fallbackValue: any,
  path: unchanged.Path,
  object: unchanged.Unchangeable,
  ...extraParams?: any[]
): any;

Get the return value of fn based on the value at the path requested on the object passed, falling back to fallbackValue when no match is found at path. When a match is found, fn is called with the current value at the path as the first parameter, and any additional parameters passed as extraParams following that.

const object: unchanged.Unchangeable = {
  foo: [
    {
      bar: "baz"
    }
  ]
};
const fn: unchanged.withHandler = (value: any, nullValue: any): any =>
  currentValue === nullValue ? null : currentValue;

console.log(getWithOr(fn, "quz", ["foo", 0, "bar"], object, "baz")); // null
console.log(getWithOr(fn, "quz", ["foo", 0, "notFound"], object, "baz")); // 'quz'

setWith

function setWith(
  fn: unchanged.withHandler,
  path: unchanged.Path,
  object: unchanged.Unchangeable,
  ...extraParams?: any[]
): unchanged.Unchangeable;

Returns a new object based on the object passed, with the return value of fn assigned to the final key on the path specified. fn is called with the current value at the path as the first parameter, and any additional parameters passed as extraParams following that.

const object: unchanged.Unchangeable = {
  foo: [
    {
      bar: "baz"
    }
  ]
};
const fn: unchanged.withHandler = (value: any, preventUpdate: boolean): any =>
  preventUpdate ? currentValue : "quz";

console.log(setWith(fn, "foo[0].bar", object)); // {foo: [{bar: 'quz'}]}
console.log(setWith(fn, "foo[0].bar", object, true)); // {foo: [{bar: 'baz'}]}
console.log(setWith(fn, ["foo", 0, "bar"], object)); // {foo: [{bar: 'quz'}]}
console.log(setWith(fn, ["foo", 0, "bar"], object, true)); // {foo: [{bar: 'baz'}]}

removeWith

function removeWith(
  fn: unchanged.withHandler,
  path: unchanged.Path,
  object: unchanged.Unchangeable,
  ...extraParams?: any[]
): unchanged.Unchangeable;

Returns a new object based on the object passed, with the final key on the path removed if it exists and the return from fn is truthy.

const object: unchanged.Unchangeable = {
  foo: [
    {
      bar: "baz"
    }
  ]
};
const fn: unchanged.withHandler = (
  value: any,
  shouldNotRemove: boolean
): boolean => !shouldNotRemove && value === "baz";

console.log(removeWith(fn, "foo[0].bar", object)); // {foo: [{}]}
console.log(removeWith(fn, "foo[0].bar", object, true)); // {foo: [{bar: 'baz'}]}
console.log(removeWith([fn, "foo", 0, "bar"], object)); // {foo: [{}]}
console.log(removeWith([fn, "foo", 0, "bar"], object, true)); // {foo: [{bar: 'baz'}]}

hasWith

function hasWith(
  fn: unchanged.withHandler,
  path: unchanged.Path,
  object: unchanged.Unchangeable,
  ...extraParams?: any[]
): boolean;

Returns true if the return value of fn based on the value returned from path in the object returns truthy, false otherwise.

  foo: [
    {
      bar: "baz"
    }
  ]

  fn: unchanged.withHandler,
  path: unchanged.Path,
  object: unchanged.Unchangeable
): unchanged.Unchangeable;

Returns a new object that is a deep merge of the return value of fn into object at the path specified if a valid mergeable object, else returns the original object. If you want to perform a shallow merge, see assignWith.

callWith

function callWith(
  path: unchanged.Path,
  parameters: any[],

NOTE: Because context is optional, it cannot be independently curried; you must apply it in the call when the object is passed.

Additional objects

__

A placeholder value used to identify "gaps" in a curried function, allowing for earlier application of arguments later in the argument order.

import {__, set} from 'unchanged';

const thing = {
  foo: 'foo';
};

const setFoo = set('foo', __, thing);

setFooOnThing('bar');

lodash/fp (the functional programming implementation of lodash) is identical in implementation to unchanged's methods, just with a 10.5x larger footprint. These methods should map directly:

lodash/fp => unchanged
curry.placeholder => __
get => get
getOr => getOr
merge => merge
omit => remove
set => set

ramda

ramda is similar in its implementation, however the first big difference is that dot-bracket syntax is not supported by ramda, only path arrays. The related methods are:

ramda => unchanged
__ => __
path => get
pathOr => getOr
merge => merge
omit => remove
assocPath => set

Another difference is that the ramda methods that clone (assocPath, for example) only work with objects; arrays are implicitly converted into objects, which can make updating collections challenging.

The last main difference is the way that objects are copied, example:

function Foo(value) {
  this.value = value;
}

Foo.prototype.getValue = function() {
  return this.value;
};

const foo = new Foo("foo");

// in ramda, both own properties and prototypical methods are copied to the new object as own properties
const ramdaResult = assoc("bar", "baz", foo);

console.log(ramdaResult); // {value: 'foo', bar: 'baz', getValue: function getValue() { return this.value; }}
console.log(ramdaResult instanceof Foo); // false

// in unchanged, the prototype of the original object is maintained, and only own properties are copied as own properties
const unchangedResult = set("bar", "baz", foo);

console.log(unchangedResult); // {value: 'foo', bar: 'baz'}
console.log(unchangedResult instanceof Foo); // true

This can make ramda more performant in certain scenarios, but at the cost of having potentially unexpected behavior.

Other immutability libraries

This includes popular solutions like Immutable.js, seamless-immutable, mori, etc. These solutions all work well, but with one caveat: you need to buy completely into their system. Each of these libraries redefines how the objects are stored internally, and require that you learn a new, highly specific API to use these custom objects. unchanged is unopinionated, accepting standard JS objects and returning standard JS objects, no transformation or learning curve required.

Development

Standard stuff, clone the repo and npm install dependencies. The npm scripts available:

benchmark => run benchmark suite comparing top-level and deeply-nested get and set operations with lodash and ramda
build => run rollup to build dist files for CommonJS, ESM, and UMD consumers
clean => run rimraf on the dist folder
dev => run webpack dev server to run example app / playground
dist => runs clean and build
lint => run ESLint against all files in the src folder
lint:fix => run lint with autofixing applied
prepublish => runs prepublish:compile when publishing
prepublish:compile => run lint, test:coverage, dist
test => run AVA test functions with NODE_ENV=test
test:coverage => run test but with nyc for coverage checker
test:watch => run test, but with persistent watcher
