What is Node.js?

Node.js is not a programming language, some newbies think it is, but it’s not! It is an open-source JavaScript runtime environment that executes JavaScript codes outside the browser. What Node.js simply does is repackage the functionalities and features of the JavaScript language into modules. It also upgrades it to run outside the browser which was the original run-time environment for the Language.

Because these upgrades are packaged into Node.js developers can now use JavaScript for frontend and backend development making JavaScript a full-stack language.

In the past, Node.js was only designed to serve real-time performance and push-back architectures. Since then, Node.js has developed into a crucial component of server-side scripting for event-driven, non-blocking servers. Today, Node.js powers most traditional websites and API services. Node.js uses an event-driven, non-blocking I/O architecture and the V8 JavaScript runtime engine as its primary power source.

Who Uses Node.js

Millions of websites all around the world use Node.js. It has millions of downloads as can be seen by its weekly npm installations.

JavaScript full-stack developers enjoy the comfort Node.js brings to the technology space. This is because Node.js enhances the performance of developers and facilitates the development process.

Top companies that use Node.js include:

NASA
Twitter
Netflix
LinkedIn
PayPal
GitHub
eBay
Walmart
Spotify
Medium

If you research these companies, you will notice that they base their companies’ operations on numerous services or goods. However, they all share a vital characteristic which is that they all rely on Node.js. No matter what business you’re in, employing Node.js can solve most of your development problems.

Secondly, you may work on server-side coding by having a basic grasp of an object-oriented programming (OOP) language.

1. Hardware Requirements

Below are the hardware requirements for installing Node.js on Ubuntu.

Node.js does not need a complex hardware configuration to work; most machines nowadays are compatible.
Node.js installation requires a stable hard drive for it to work.
You should have the necessary prerequisites to install Node.js on Ubuntu.
Virtually all modem computers can run Node.Js, including miniature computers like BeagleBone or Arduino YÚN.
The Random-Access Memory (RAM) of your system should be up to 4GB and your system storage should be at least 256GB of Hard Disk Space.

2. Software Requirements

Below are the software requirements for installing Node.js on Ubuntu. The web browser should be intact. Any browser such as Google Chrome, Mozilla Firefox, or Microsoft Edge can run Node.js.
Operating System should be accurate and free, having an Ubuntu server installed with a non-root Sudo user and firewall.

How to Install Node.js on Ubuntu [Step-by-Step]

Follow the three methods below to install Node.js on your Ubuntu machine.

Method 1: Installing the Stable Version for Ubuntu

Before you can install a stable version of Node.js for Ubuntu, you must update the terminal first.

Step 1: You can use the apt package manager to obtain the version that can run Node.js. Update the index for your regional package usage.

 sudo apt update

Step 2: Install Node.js from the repository in step two.

 sudo apt install Node.js

Step 3: Install npm ubuntu with the code below.

 sudo apt install npm

Step 4: Use this to check which Node.js version you installed.

 Node.js -v && npm --version

And there you have it for this method. If you want to upgrade your JavaScript skills, visit the Full Stack Developer course to enhance your development skill.

Method 2: Install Node.js Using a PPA
Software repositories of various packages specifically created for Ubuntu 20.14 users are included in the PPA repository. The PPA repository for the most recent Node.js version is added first.

Before installing Node.js using PPA, ensure that you have the curl command-line utility installed on your system. If curl isn’t installed on your system paste this command on your terminal to install curl:

sudo apt install curl

After installing curl add the Node.js source with the following code.

 curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash -

If you experience an issue with the public such as “the following signatures couldn’t be verified because the public key is not available”

Now, on the console, you should see the public key; copy it, replace it in the space below, and run it on the terminal.

 sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys

Now run the command below to install Node.js npm Ubuntu 20.04 on your machine.

sudo apt-get install -y Node.js

If you’ve done everything correctly, Node.js will successfully install on your Linux distribution. To check node version Ubuntu, run the command shown below and the newest version is installed.
