Task: Create an HTTP Server That Serves Different Messages Based on Routes

Step-by-Step Procedure:

1. Step 1: Create a File Named multiRouteServer.js:

   • Write the following code:

     const http = require('http');
     
     const server = http.createServer((req, res) => {
         console.log(`Request Method: ${req.method}, URL: ${req.url}`);
     
         if (req.url === '/') {
             res.writeHead(200, { 'Content-Type': 'text/plain' });
             res.end('Welcome to the Home Page');
         } else if (req.url === '/about') {
             res.writeHead(200, { 'Content-Type': 'text/plain' });
             res.end('This is the About Page');
         } else if (req.url === '/contact') {
             res.writeHead(200, { 'Content-Type': 'text/plain' });
             res.end('Contact us at [email protected]');
         } else {
             res.writeHead(404, { 'Content-Type': 'text/plain' });
             res.end('404 Not Found');
         }
     });
     
     server.listen(3000, () => {
         console.log('Server running at http://localhost:3000');
     });

2. Step 2: Run the Server:

   • Open the terminal and run:

     //bash
     node multiRouteServer.js

3. Step 3: Test the Server:

   • Use Postman or a browser to test the following routes:

     • GET http://localhost:3000/: Returns "Welcome to the Home Page".

     • GET http://localhost:3000/about: Returns "This is the About Page".

     • GET http://localhost:3000/contact: Returns "Contact us at [email protected]".

     • GET http://localhost:3000/unknown: Returns "404 Not Found".

4. Step 4: Observe the Logs:

   • Check the terminal for logs showing the request method and URL for each request.

Expected Outcomes

1. Students build a basic understanding of HTTP servers and REST principles.

2. Students gain hands-on experience with routing and debugging HTTP requests.

3. Homework reinforces learning through practical implementation of multi-route servers.
