Express.js is a web application framework for Node.js, designed to make it easier to build web applications and APIs. Here's a basic guide on how to use Express.js with Node.js:

1. Install Node.js and npm:

Make sure you have Node.js and npm (Node Package Manager) installed on your machine. You can download them from the official website: Node.js Downloads.

2. Create a new Node.js project:

Create a new directory for your project and navigate to it in the terminal. Run the following command to initialize a new Node.js project:

bash
npm init -y

This will create a package.json file with default values.

3. Install Express.js:

Install Express.js as a dependency for your project using the following command:

bash
npm install express

4. Create an Express application:

Create a new file (e.g., app.js) and set up a basic Express application:

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

5. Run your Express application:

In the terminal, run the following command to start your Express application:

bash
node app.js

Visit http://localhost:3000 in your web browser, and you should see the message "Hello, Express!"

6. Create Routes and Handle Requests:

Expand your application by adding more routes and handling different HTTP methods. For example:

javascript
// Define a route with parameters app.get('/users/:userId', (req, res) => { const userId = req.params.userId; res.send(`User ID: ${userId}`); }); // Handle POST requests app.post('/users', (req, res) => { res.send('User created!'); });

7. Use Middleware:

Express allows you to use middleware functions to perform additional tasks during the request-response cycle. For example, adding a middleware to log requests:

javascript
app.use((req, res, next) => { console.log(`Received a ${req.method} request to ${req.url}`); next(); });

These are the basic steps to get started with Express.js in a Node.js project. You can explore more features and advanced concepts in the Express.js documentation.
