I want to make an SSH connection using Node.js or JavaScript so that I connect it through a web page and run the commands. How can I do this?

There is a very good library, node-ssh. It supports promises too. Have a look at that.
Code copied from the official documentation:
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')
})
.then(function() {})
Edit-I have tried this code in my system and its working
var path, node_ssh, ssh,
fs
fs = require('fs')
path = require('path')
node_ssh = require('node-ssh')
ssh = new node_ssh()
ssh.connect(
{ host: 'Your host', username: 'username', password: 'yourpass',
})
.then(function(response) {console.log(response)})

You can remove the privatekey parameter @Nandini

getting an error like this: (node:584) UnhandledPromiseRejectionWarning: Error: config.privateKey must be a string

Means I just created new file and tried to run the above code.

var path, node_ssh, ssh, fs fs = require('fs') path = require('path') node_ssh = require('node-ssh') ssh = new node_ssh() ssh.connect({ host: '192.168.0.159', username: 'hduser1', password: '123' //privateKey: fs.readFileSync('C:/Users/NANDINI CHITTI/Desktop/Migration Tool/id_rsa') }) .then(function() {}) console.log('SSH connecting....') this the code

Thank you @shubh . I got it. and if I want to run any commands How do I do that

If you're using Node.js to SSH into a server, you have a couple of solid options: ssh2 and hivessh. ssh2 has a callback approach that can be unmaintainable and ugly if you use a lot of nested or dependent ssh operations.
Hivessh is an ssh2 wrapper that provides a promise based approach with some nice utilities. like checking if a command exists.
