In this blog, we will cover various NodeJS Projects for Beginners that can be useful to them. Big organizations like Uber, Facebook, and Amazon use NodeJS for their applications. Not only these, but popular full-stack technologies like MERN and MEAN also use NodeJS.
Before looking into top NodeJS projects, let’s have a look at what NodeJS is.
What is NodeJS?
NodeJS is a cross-platform, open-source JavaScript runtime server and library for operating web applications outside the company’s browser. It was created in 2009 by Ryan Dahl.
Last year in April 2021, a new version of NodeJS 15.14 was released and is used by the developers to create the service side of web applications and is ideal for applications that are data insensitive as their models are highly synchronized and event-driven.
What are the uses of NodeJS?
There are several reasons why developers prefer using NodeJS for the server side of an application.
- NodeJs is built on Google Chrome’s Engine, and its processing time and speed are extremely fast.
- NodeJS Package Manager contains over 50,000 stacks. Developers can transfer any of the bundles at any time based on the operability they require, saving a significant amount of time.
- NodeJs does not require anyone to wait for an API to revert back the data, it is ideal for developing genuine time and data-intensive web applications. It is completely non-parallel in nature, which indicates it is completely non-blocking.
- NodeJs reduces the loading speed for a sound or video file because it provides good code quality synchronization between the server and the client for possessing a similar code base.
- Since NodeJs is an open source and is nothing more than a JavaScript framework, it is simple for developers who are previously familiar with JavaScript to begin developing their projects with NodeJs.
Features of NodeJS
- Single Thread Architecture:
NodeJs employs a single-threaded architecture along with activity looping, which makes it more workable. Compared to other domains, NodeJs creates a restricted number of threads to implement requests. Compared to the event-driven method, NodeJS servers respond in a non-blocking or adaptive manner, which makes it more scalable.
Compared to other traditional standard servers, such as Apache HTTP servers, NodeJs deals with a greater volume of requests and uses a single-threaded program, which enables it to handle a large number of requests.
- NodeJS is Scalable:
Nowadays, the majority of businesses require scalable software. Scalability is among the most urgent issues, in software programming and NodeJs addresses it. NodeJs can understand and manage requests very proficiently. NodeJs employs a clump module to manage task scheduling across all active CPU cores.
The most attractive aspect of NodeJs is its ability to divide applications horizontally, which it accomplishes primarily through basic processes. By using this feature, various application versions are provided to a variety of target audiences, and personalization enables them to accommodate client preferences.
- Quick code execution: NodeJs uses the V8 JavaScript duration motor, which is also used by Google Chrome. The control systems packaging for the JavaScript, which speeds up the run-time motor and as a result, speeds up the implementation process of the requests inside NodeJs.
- Cross-platform compatibility: NodeJs can be used on a wide range of systems, including Windows, LINUX, MacOS, and many other mobile devices. It can be combined with any best-choice package to generate a self-sufficient implementation.
- High-Speed Data Streaming: Usually, it takes a very long time to process information and data that has been transferred to various streams. NodeJs, on the other hand, process data in quite less amount of time and at a rapid rate. NodeJS saves plenty of time because it processes and uploads files at the same time. As a result, NodeJs enhances the general speed of information and video streaming.

Because NodeJS is easy to operate as a programming language, it has also become very popular among major organizations for their applications. According to a survey by Stack Overflow, there are over 65,000 developers who have shifted to NodeJS for development purposes. Companies that use NodeJS are:
- Netflix: NodeJS, along with JavaScript, helped Netflix to transform its website into a single-page application by making changes in the back end of its website.
- Uber: Uber is one of the first companies to adopt NodeJS for their application development. They create systems that help a user to book or cancel a ride through their application.
- LinkedIn: They have used various technologies but according to a developer at LinkedIn, they have used NodeJS for their back-end processes.
Why should you learn NodeJS?
NodeJS is the perfect skill to start your career as a developer. This skill opens up amazing career opportunities. As it is very clear that every programming language has its benefits, the question is why NodeJS is more popular and in demand than any other language. Why are developers learning NodeJS? The answers to these questions are:-
- NodeJS develops real-time applications. The synchronization process of NodeJS is very fast compared to other programming languages. It makes RTA scalable, usable, and lightweight.
- As Chrome V8 Engine powers it, NodeJS provides a runtime that executes JavaScript speed. Paypal used NodeJS for their application and found that their application was built twice fast, with 33% fewer code lines and 40% fewer files. More notably, they doubled the number of requests delivered per second while reducing the average response time by 35%. As a result, Node is a great choice for creating highly scalable applications.
- NodeJS streams allow applications to use less storage while interacting with huge amounts of data, allowing them to run faster. This feature is handy for developers working on real-time sound or video encoding.
- The number of companies that use NodeJS for developing applications is growing all the time. It includes nearly 300 notable companies, such as Medium and Uber.
- There is a low learning curve. A developer who is already familiar with JavaScript can easily learn NodeJS as both of them are very similar to each other.

Below is how code can be created using NodeJS for building a book directory.
const express = require(‘express’);
const router = express.Router();
const books = require(‘./books.json’);
// Get all the books
router.get(‘/’, (req, res) => {
res.json(books);
});
// Get a specific book
router.get(‘/:id’, (req, res) => {
const { id } = req.params;
res.json(books.filter((ele) => ele.id === parseInt(id)));
});
router.post(‘/’, (req, res) => {
const body = req.body;
console.log(body);
books.push(body);
res.json({ message: ‘The book has been added’ });
});
router.put(‘/:id’, (req, res) => {
const { id } = req.params;
const body = req.body;
books.forEach((book, index) => {
if (book.id === parseInt(id)) {
books[index] = body;
}
});
res.json({ message: `The book with ID ${id} has been updated` });
// res.json(books);
});
router.delete(‘/:id’, (req, res) => {
