scp2

A pure javascript secure copy program based on ssh2.

---

scp2 is greatly powered by ssh2, implementing scp in an sftp way.

It is written in pure javascript, and should work on every OS, even Windows. Nodejs (v0.8.7 or newer) is required to use this library.

Install

You can either use it as a library, or via CLI. For Windows users who miss scp in the unix/linux world, you can get it with:

$ npm install scp2 -g

You will get a command line tool scp2, now let's try:

$ scp2 -h

To get the development version from the ninja channel:

$ npm install scp2@ninja

High level API

Get the client:

var client = require('scp2')

Copy a file to the server:

client.scp('file.txt', 'admin:password@example.com:/home/admin/', function(err) {
})

You can also add the port to the url (default is 22):

client.scp('file.txt', 'admin:password@example.com:port:/home/admin/', function(err) {
})

Copy a file to the server specifying the destination as an object:

client.scp('file.txt', {
    host: 'example.com',
    username: 'admin',
    password: 'password',
    path: '/home/admin/'
}, function(err) {})

Copy a file to the server and rename it:

client.scp('file.txt', 'admin:password@example.com:/home/admin/rename.txt', function(err) {
})

Copy a directory to the server:

client.scp('data/', 'admin:password@example.com:/home/admin/data/', function(err) {
})

Copy via glob pattern:

client.scp('data/*.js', 'admin:password@example.com:/home/admin/data/', function(err) {
})

Download a file from the server:

client.scp('admin:password@example.com:/home/admin/file.txt', './', function(err) {
})

Download a file from the server specifying the destination as an object:

client.scp({
    host: 'example.com',
    username: 'admin',
    password: 'password',
    path: '/home/admin/file.txt'
}, './', function(err) {})

Login with a private key:

client.scp('file.txt', {
    host: 'example.com',
    username: 'admin',
    privateKey: require("fs").readFileSync('path/to/private/key'),
    passphrase: 'private_key_password',
    path: '/home/admin/'
}, function(err) {})

TODO: download via glob pattern.

Low level API

Get the client:

var Client = require('scp2').Client;

The high level client is an instance of Client, but also contains the high level API scp.

Methods

• defaults function({})

  set the default values for the remote server.

  client.defaults({
      port: 22,
      host: 'example.com',
      username: 'admin',
      privateKey: '....',
      // password: 'password', (accepts password also)
  });

  You can also initialize the instance with these values:

  var client = new Client({
      port: 22
  });

  More on these values at ssh2.

• sftp function(callback) -> callback(err, sftp)

  Get the sftp object.

• close function()

  Close all sessions.

• mkdir function(dir, [attr], callback) -> callback(err)

  Make a directory on the remote server. It behaves like mdkir -p.

• write function(options, callback) -> callback(err)

  Write content on the remote server.

  client.write({
      destination: '/home/admin/data/file.txt',
      content: 'hello world'
  }, callback)

  The options object can contain:

  • destination
  • content: string or buffer
  • attrs
  • source: the source path, e.g. local/file.txt

• upload function(src, dest, callback) -> callback(err)

  upload a local file to the server.

  client.upload('file.txt', '/home/admin/file.txt', callback)

• download function(src, dest, callback) -> callback(err)

  download a file from the server to local.

Events

You can listen for these events:

• connect
• ready
• error (err)
• end
• close
• mkdir (dir)
• write (object)
• read (src)
• transfer (buffer, uploaded, total)
