Node-SSH - SSH2 with Promises
=========
Node-SSH is an extremely lightweight Promise wrapper for [ssh2][ssh2].
#### Installation
```sh
$ npm install node-ssh # If you're using npm
$ yarn add node-ssh # If you're using Yarn
```
#### Example
```js
const fs = require('fs')
const path = require('path')
const {NodeSSH} = require('node-ssh')
const ssh = new NodeSSH()
ssh.connect({
host: 'localhost',
username: 'steel',
privateKeyPath: '/home/steel/.ssh/id_rsa'
})
// or with inline privateKey
ssh.connect({
host: 'localhost',
username: 'steel',
privateKey: Buffer.from('...')
})
.then(function() {
// Local, Remote
ssh.putFile('/home/steel/Lab/localPath/fileName', '/home/steel/Lab/remotePath/fileName').then(function() {
console.log("The File thing is done")
}, function(error) {
console.log("Something's wrong")
console.log(error)
})
// Array string, 'remote' => string)>
ssh.putFiles([{ local: '/home/steel/Lab/localPath/fileName', remote: '/home/steel/Lab/remotePath/fileName' }]).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 = []
const successful = []
ssh.putDirectory('/home/steel/Lab', '/home/steel/Lab', {
recursive: true,
concurrency: 10,
// ^ WARNING: Not all servers support high concurrency
// try a bunch of values and see what works on your server
validate: function(itemPath) {
const baseName = path.basename(itemPath)
return baseName.substr(0, 1) !== '.' && // do not allow dot files
baseName !== 'node_modules' // do not allow node_modules
},
tick: function(localPath, remotePath, error) {
if (error) {
failed.push(localPath)
} else {
successful.push(localPath)
}
}
}).then(function(status) {
console.log('the directory transfer was', status ? 'successful' : 'unsuccessful')
console.log('failed transfers', failed.join(', '))
console.log('successful transfers', successful.join(', '))
})
// Command
ssh.execCommand('hh_client --json', { cwd:'/var/www' }).then(function(result) {
console.log('STDOUT: ' + result.stdout)
console.log('STDERR: ' + result.stderr)
})
// Command with escaped params
ssh.exec('hh_client', ['--json'], { cwd: '/var/www', stream: 'stdout', options: { pty: true } }).then(function(result) {
console.log('STDOUT: ' + result)
})
// With streaming stdout/stderr callbacks
ssh.exec('hh_client', ['--json'], {
cwd: '/var/www',
onStdout(chunk) {
console.log('stdoutChunk', chunk.toString('utf8'))
},
onStderr(chunk) {
console.log('stderrChunk', chunk.toString('utf8'))
},
})
})
```

### Typescript support
`node-ssh` requires extra dependencies while working under Typescript. Please install them as shown below
```
yarn add --dev @types/ssh2
# OR
npm install --save-dev @types/ssh2
```
If you're still running into issues, try adding these to your `tsconfig.json`
```json
{
"compilerOptions": {
"moduleResolution": "node",
"allowSyntheticDefaultImports": true
}
}
```
### Keyboard-interactive user authentication
In some cases you have to enable keyboard-interactive user authentication.
Otherwise you will get an `All configured authentication methods failed` error.
#### Example:
```js
const password = 'test'
ssh.connect({
host: 'localhost',
username: 'steel',
port: 22,
password,
tryKeyboard: true,
})
// Or if you want to add some custom keyboard-interactive logic:
ssh.connect({
host: 'localhost',
username: 'steel',
port: 22,
tryKeyboard: true,
onKeyboardInteractive(name, instructions, instructionsLang, prompts, finish) {
if (prompts.length > 0 && prompts[0].prompt.toLowerCase().includes('password')) {
finish([password])
}
}
})
```
