Overview of Express JS Routing

Express JS is a popular web framework for Node JS that simplifies the process of building web applications. One of the key features of Express JS is its routing system, which allows developers to define routes and handle requests based on those routes. Routing in Express JS is done using the app.get(), app.post(), app.put(), and app.delete() methods.

Step-by-Step Tutorial

Let’s walk through a step-by-step tutorial to understand Express JS routing:

1. Create a new Express JS project:

const express = require('express');
const app = express();

2. Define a route using the app.get() method:

app.get('/', (req, res) => {
  res.send('Hello, World!');
});

3. Start the server:

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

4. Visit http://localhost:3000 in your browser to see the message “Hello, World!” displayed.

Conclusion

Express JS routing is a powerful feature that helps in creating structured and organized web applications. By defining routes and handling requests, developers can build dynamic and interactive web applications easily.
