Node-SSH - SSH2 with Promises

Node-SSH is an extremely lightweight Promise wrapper for ssh2, Period.

Example

var path, node_ssh, ssh, fs

fs = require('fs')
path = require('path')
node_ssh = require('node-ssh')
ssh = new node_ssh()

ssh.connect({
  host: 'localhost',
  username: 'steel',
  privateKey: '/home/steel/.ssh/id_rsa'
})
/*
 Or
 ssh.connect({
   host: 'localhost',
   username: 'steel',
   privateKey: fs.readFileSync('/home/steel/.ssh/id_rsa')
 })
 if you want to use the raw string as private key
 */
.then(function() {
  // Local, Remote
  ssh.putFile('/home/steel/Lab/localPath', '/home/steel/Lab/remotePath').then(function() {
    console.log("The File thing is done")
  }, function(error) {
    console.log("Something's wrong")
    console.log(error)
  })
  // Array<Shape('local' => string, 'remote' => string)>
  ssh.putFiles([{ local: '/home/steel/Lab/localPath', remote: '/home/steel/Lab/remotePath' }]).then(function() {
    console.log("The File thing is done")
  }, function(error) {
    console.log("Something's wrong")
    console.log(error)
  })
  // Local, Remote
  ssh.getFile('/home/steel/Lab/localPath', '/home/steel/Lab/remotePath').then(function(Contents) {
    console.log("The File's contents were successfully downloaded")
  }, function(error) {
    console.log("Something's wrong")
    console.log(error)

  // Putting entire directories
  const failed = []

  ssh.execCommand('hh_client --json', { cwd:'/var/www' }).then(function(result) {

  // Command with escaped params
  ssh.exec('hh_client', ['--json'], { cwd: '/var/www', stream: 'stdout' }).then(function(result) {
    console.log('STDOUT: ' + result)
  })
})
