In this article, We are going to perform How to Install Latest Node.js and NPM on Ubuntu 19.04,18.04/16.04 LTS and any other cloud platform like Azure, EC2, Compute Engine.
Introdution
Node.js is free and an open-source cross-platform JavaScript run-time environment that allows server-side execution of JavaScript code. It is used in developing web and networking applications.
NPM(Node Package Manager) is command line tool for Node.js packages that installs, updates and uninstall packages in your projects.We don’t have install npm separately it is includes with Node.js installation.
Prerequisites
- Ubuntu 19.04, 18.04/16.04 LTS
- SSH access with sudo privileges

Before installing, We have to install curl and add Node.js from Nodesource repository.
$ sudo apt-get install curl
Current Release
Node.js 12 is the current release.
$ curl -sL https://deb.nodesource.com/setup_12.x | bash -Latest Release
In this article , We are installing Node.js 10.16.3 latest version.
$ curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -Output:
+ curl -sLf -o /dev/null 'https://deb.nodesource.com/node_10.x/dists/xenial/Release' ## Adding the NodeSource signing key to your keyring... + curl -s https://deb.nodesource.com/gpgkey/nodesource.gpg.key | apt-key add - OK ## Creating apt sources list file for the NodeSource Node.js 10.x repo... + echo 'deb https://deb.nodesource.com/node_10.x xenial main' > /etc/apt/sources.list.d/nodesource.list + echo 'deb-src https://deb.nodesource.com/node_10.x xenial main' >> /etc/apt/sources.list.d/nodesource.list ## Running `apt-get update` for you... ## Run `sudo apt-get install -y nodejs` to install Node.js 10.x and npm ## You may also need development tools to build native addons: sudo apt-get install gcc g++ make ## To install the Yarn package manager, run: curl -sL https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add - echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list sudo apt-get update && sudo apt-get install yarn
Step 2: Install Latest Node.js and NPM on Ubuntu

Processing triggers for man-db (2.7.5-1) ... Setting up nodejs (10.16.3-1nodesource1) ...
Step 3: Check Node.js and NPM Version on Ubuntu
After installation, check Node.js version by entering below command,
$ node --version
Output:
$ node --version v10.16.3
To Check NPM version.
$ npm --version
Output:
$ npm --version 6.9.0
Step 4: Testing Node.js Server
const http = require('http');
const hostname = '127.0.0.1';
const port = 3000;
const server = http.createServer((req, res) => {
res.statusCode = 200;
res.setHeader('Content-Type', 'text/plain');
res.end('Hello World\n');
});
server.listen(port, hostname, () => {
console.log(`Server running at http://${hostname}:${port}/`);
});
Run your Node.js server with the below command,
$ node nodeapp.js
Output:
$ node nodeapp.js
Server running at http://127.0.0.1:3000/
Now open your browser and type server name or IP followed by port 3000, you will see Hello World message.
http://127.0.0.1:3000

Conclusion:
In this article, We have performed ,How to Install Latest Node.js and NPM on Ubuntu 19.04,18.04/16.04 LTS, Checked Node.js and NPM version and performed to uninstall node.js and NPM from ubuntu.
