What is ExpressJS?

ExpressJS, often simply referred to as Express, is a lightweight and open-source web application framework for Node.js. Its primary purpose is to streamline the creation of web applications and APIs by providing a set of tools and features that simplify complex tasks. ExpressJS is built on top of Node.js, leveraging its asynchronous and event-driven architecture to build fast and efficient applications.

Getting Started:

1. Setting Up Node.js: Before diving into ExpressJS, ensure you have Node.js installed on your system. You can download it from the official Node.js website (https://nodejs.org) and follow the installation instructions.

 2. Creating a Basic Express Application:

  To create a new Express application, follow these steps:

  • Open your terminal and navigate to the desired directory.
  • Run the following commands:

“bash

 mkdir my-express-app

    cd my-express-app

     npm init -y

     npm install express

3. Creating Your First Route:

  • Express revolves around the concept of routes, which define how your application responds to different HTTP requests. Here's a simple example of creating a route that responds with "Hello, Express!" when accessed:

“javascript   const express = require('express'); const app = express(); app.get('/', (req, res) => {

res.send('Hello, Express!'); });  app.listen(3000, () => {

console.log('Server is running on port 3000'); });

“ 

4. Middleware:

  • Middleware functions in Express are essential for handling tasks such as authentication, logging, and data validation. They sit between the initial request and the final route handler. Here's a quick example of adding middleware to log incoming requests:

“javascript

   app.use((req, res, next) => {

console.log(`Request received at: ${new Date()}`);

next(); });
