node scp node scp async node-scp node-scp-async scp node scp nodejs

New SCP module for NodeJS

A lightweight, fast and secure module to perform SCP commands for NodeJS based on SSH2

What's new

All functionalities are written using Promise. That means you can use it with Promise or Async/Await (No more callback hell, Yeah :) )

And other new features:

Scp a directory from local to remote server and from remote to local
Perform commands on remote server: mkdir, stat, check if path exists

Installation

npm install --save node-scp
# or
yarn add node-scp

Guide

Scp file from local to remote server

Using Promise

// with commonJS
const { Client } = require('node-scp')

// with ES Module
import { Client } from 'node-scp'

Client({
  host: 'your host',
  port: 22,
  username: 'username',
  password: 'password',
  // privateKey: fs.readFileSync('./key.pem'),
  // passphrase: 'your key passphrase',
}).then(client => {
  client.uploadFile(
    './test.txt',
    '/workspace/test.txt',
    // options?: TransferOptions
  )
        .then(response => {
          client.close() // remember to close connection after you finish
        })
        .catch(error => {})
}).catch(e => console.log(e))

Using async/await:

// with commonJS
const { Client } = require('node-scp')

// with ES Module
import { Client } from 'node-scp'

async function test() {
  try {
    const client = await Client({
      host: 'your host',
      port: 22,
      username: 'username',
      password: 'password',
      // privateKey: fs.readFileSync('./key.pem'),
      // passphrase: 'your key passphrase',
    })
    await client.uploadFile(
      './test.txt',
      '/workspace/test.txt',
      // options?: TransferOptions
    )
    // you can perform upload multiple times
    await client.uploadFile('./test1.txt', '/workspace/test1.txt')
    client.close() // remember to close connection after you finish
  } catch (e) {
    console.log(e)

Events

You can listen for any event provided by SSH2 during an SSH session by passing events to Connection options

For example:

try {
  const client = await Client({
    host: "server_ip",
    port: 22,
    username: "username",
    tryKeyboard: true,
    events: {
      "keyboard-interactive": (
        name,
        instructions,
        instructionsLang,
        prompts,
        finish
      ) => {
        finish(['my_password'])
      },
    },
  });

  client.close(); // remember to close connection after you finish
} catch (e) {
  console.log(e);
}

authHandler - mixed - Either an array of objects as described below or a function with parameters (methodsLeft, partialSuccess, callback) where methodsLeft and partialSuccess are null on the first authentication attempt, otherwise are an array and boolean respectively. Return or call callback() with either the name of the authentication method or an object containing the method name along with method-specific details to try next (return/pass false to signal no more methods to try). Valid method names are: 'none', 'password', 'publickey', 'agent', 'keyboard-interactive', 'hostbased'. Default: function that follows a set method order: None -> Password -> Private Key -> Agent (-> keyboard-interactive if tryKeyboard is true) -> Hostbased

When returning or calling callback() with an object, it can take one of the following forms:

{
  type: 'none',
  username: 'foo',
}

{
  type: 'password'
  username: 'foo',
  password: 'bar',
}

{
  type: 'publickey'
  username: 'foo',
  // Can be a string, Buffer, or parsed key containing a private key
  key: ...,
  // `passphrase` only required for encrypted keys
  passphrase: ...,
}

{
  type: 'hostbased'
  username: 'foo',
  localHostname: 'baz',
  localUsername: 'quux',
  // Can be a string, Buffer, or parsed key containing a private key
  key: ...,
  // `passphrase` only required for encrypted keys
  passphrase: ...,
}

{
  type: 'agent'
  username: 'foo',
  // Can be a string that is interpreted exactly like the `agent`
  // connection config option or can be a custom agent
  // object/instance that extends and implements `BaseAgent`
  agent: ...,
}

{
  type: 'keyboard-interactive'
  username: 'foo',
  // This works exactly the same way as a 'keyboard-interactive'
  // Client event handler
  prompt: (name, instructions, instructionsLang, prompts, finish) => {
    // ...
  },
}

debug - function - Set this to a function that receives a single string argument to get detailed (local) debug information. Default: (none)
forceIPv4 - boolean - Only connect via resolved IPv4 address for host. Default: false
forceIPv6 - boolean - Only connect via resolved IPv6 address for host. Default: false
host - string - Hostname or IP address of the server. Default: 'localhost'
hostHash - string - Any valid hash algorithm supported by node. The host's key is hashed using this algorithm and passed to the hostVerifier function as a hex string. Default: (none)
hostVerifier - function - Function with parameters (hashedKey[, callback]) where hashedKey is a string hex hash of the host's key for verification purposes. Return true to continue with the handshake or false to reject and disconnect, or call callback() with true or false if you need to perform asynchronous verification. Default: (auto-accept if hostVerifier is not set)
keepaliveCountMax - integer - How many consecutive, unanswered SSH-level keepalive packets that can be sent to the server before disconnection (similar to OpenSSH's ServerAliveCountMax config option). Default: 3
keepaliveInterval - integer - How often (in milliseconds) to send SSH-level keepalive packets to the server (in a similar way as OpenSSH's ServerAliveInterval config option). Set to 0 to disable. Default: 0
localAddress - string - IP address of the network interface to use to connect to the server. Default: (none -- determined by OS)
localHostname - string - Along with localUsername and privateKey, set this to a non-empty string for hostbased user authentication. Default: (none)
localPort - string - The local port number to connect from. Default: (none -- determined by OS)
localUsername - string - Along with localHostname and privateKey, set this to a non-empty string for hostbased user authentication. Default: (none)
passphrase - string - For an encrypted privateKey, this is the passphrase used to decrypt it. Default: (none)
password - string - Password for password-based user authentication. Default: (none)
port - integer - Port number of the server. Default: 22
privateKey - mixed - Buffer or string that contains a private key for either key-based or hostbased user authentication (OpenSSH format). Default: (none)
readyTimeout - integer - How long (in milliseconds) to wait for the SSH handshake to complete. Default: 20000
sock - ReadableStream - A ReadableStream to use for communicating with the server instead of creating and using a new TCP connection (useful for connection hopping).
strictVendor - boolean - Performs a strict server vendor check before sending vendor-specific requests, etc. (e.g. check for OpenSSH server when using openssh_noMoreSessions()) Default: true
tryKeyboard - boolean - Try keyboard-interactive user authentication if primary user authentication method fails. If you set this to true, you need to handle the keyboard-interactive event. Default: false
username - string - Username for authentication. Default: (none)
events - Object - List of events to listen to. Default: (none)
