Introduction

In this post, I’m going to explore some of the most important open source nodejs based applications. NodeJS is a server-side platform that’s built on the google chrome v8 engine. Node.js is an open-source, cross-platform, back-end, JavaScript runtime environment that executes JavaScript code outside a web browser.

1- Express.js

 

Express.js, simply called express, is an open source backend nodejs framework. it is using in building a web applications and APIs. Express initially released in 2010 and it is open source. Express is main part in javascript based technology called MEAN stack, where express represent the backend part in MEAN stack. MEAN stack stands for MongoDB, ExpressJS, Angular, and Node.js. To start with express,

$ mkdir app1
    $ cd app1
    $ npm init 

Create file app.js and add the following code

    const express = require('express')
    const app = express()
    const port = 3000
    
    app.get('/', (req, res) => {
      res.send('Hello World!')
    })
    
    app.listen(port, () => {
      console.log(`Example app listening at http://localhost:${port}`);
    }) 

2- NestJS

A progressive framework of NodeJS for creating reliable, efficient, and scalable server-side apps. NestJS is fully supported TypeScript and you can use object oriented, functional programming, functional reactive programming. Under the hood, Nest makes use of robust HTTP Server frameworks like Express (the default) and optionally can be configured to use Fastify as well!

3- ESlint

ESlint can be used to find problems in your code, fix such problems automatic and customize and use custom rules.

4- Axios

Axios can be used to send asynchronous HTTP request to REST endpoints and perform CRUD operations. Axios is very popular project at github, Axios is promise-based HTTP client for JavaScript which can be used in your front-end application and in your Node. js backend

5- Socket.io

Socket.io is a JavaScript library for realtime web applications. Socket.io can be used in real-time, bi-directional and event-based communication. When a new message received at the server, the server will send this message to all the clients
