The modern web now includes a significant amount of Node.js. With it, web apps can be developed and released quickly.
Node.js is a popular and very well-known JavaScript runtime environment that is used for building scalable and high-performance applications but also a network-based web runtime environment.
JavaScript can be run outside of the browser using the open-source Node.js cross-platform environment. You may also run scripts on the server side with Node.js to create dynamic websites. You may consolidate your online application around a single programming language, Node.js, rather than employing various server-side and client-side languages, greatly simplifying your burden.
It enables you to run JavaScript on your computer as a standalone application.
Back-end server-side application development is a common practice.
It allows programmers to design scalable backend functionality using JavaScript, a language that many are already accustomed to through browser-based web development.
The largest software registry in the world, npm, is the name of the Node.js default package manager.
In this blog post, we will provide a complete installation guide for installing Node.js on Ubuntu 16.04 machine, ensuring that you have everything set up correctly. By the end of this blog, you will be ready to harness the full potential of Node.js for your development projects.
Characteristics
- Developers are experimenting with and integrating Node.js more frequently as an interface technology. This utility is now utilized by many popular web applications and tools. Here are a few of the most important general functions of Node Js.
- Because Nodejs utilizes push technologies over sockets, it is more suited for real-time web applications.
- It is data-driven, lightweight, and effective.
- The ability to support many more links running simultaneously.Because it just uses one thread, it uses less energy and delivers content more quickly.
- It makes certain that the development of the front end and the back end is done consistently.
- Testing the Node Js framework has turned out to be considerably easier when using both automated processes and scripts.
- A package manager for Node.js
This is mostly used to load node programmes. It can also be utilized during the implementation phase because it makes it simple to specify and link dependencies.This utility only works with the command prompt or shell, and To get started with Node Js app dependencies, you need to have a basic understanding of DOS or Shell.
- Type the next line to look up the Node.js version you've installed:
nodejs -v
- You will choose whether to deal with distinct releases, file files, or version managers after installing the Node.js update from the Ubuntu repository.
Prerequisites
Make sure you have everything you need before we start the installation procedure. . Here are the prerequisites for installing Node.js on Ubuntu 16.04:
- A machine running Ubuntu 16.04.
- A user account with sudo privileges.
- An internet connection.
Step 1: Update the System
To make sure that all packages are current, update the system first.and then run the following command after opening a terminal window:
sudo apt-get update
This command will update the package list and ensure that the system is up to date.
Step 2: Install Node.js
There are a few different ways to install Node.js on Ubuntu 16.04, but the easiest method is to use the Node.js package manager (npm).The command to use to install npm is:
sudo apt-get install npm
Once npm is installed, you can use it to install Node.js.To install npm, use the following command:
sudo npm install -g n
sudo n stable
This command will install the latest stable version of Node.js and set it as the default version.
Step 3: Verify the Installation
Once the installation is complete, it's crucial to verify if Node.js is correctly installed on your Ubuntu 16.04 system. We will guide you through a simple verification process to ensure everything is working as expected.
node -v
This command will display the version of Node.js that is currently installed on your computer.
Step 4: Install a Text Editor
To write and edit Node.js code, you will need a text editor. There are many text editors available for Ubuntu, but one of the most popular is Visual Studio Code. To install Visual Studio Code, enter the following command:
sudo snap install --classic code
This command will install Visual Studio Code and add it to your system.
Step 5: Create a Sample Application
To test that Node.js is working correctly, you can create a sample application. Open Visual Studio Code and create a new file called app.js.
Add the next line of code to this file:
console.log('Hello, world!');
Save the file and open a terminal window. Navigate to the directory where the app.js file is located and run the following command:
node app.js
This command will run the app.js file and display the message "Hello, world!" in the terminal window.
