Activity: Building and Testing a Basic HTTP Server

Step-by-Step Procedure:

1. Step 1: Set Up a Basic HTTP Server:

   • Create a file named basicServer.js and write the following code:

     const http = require('http');
     
     const server = http.createServer((req, res) => {
         res.writeHead(200, { 'Content-Type': 'application/json' });
         res.end(JSON.stringify({ message: 'Hello, World!' }));
     });
     
     server.listen(3000, () => {
         console.log('Server running at http://localhost:3000');
     });

2. Step 2: Run the Server:

   • Open a terminal, navigate to the file location, and run:

     // bash
     node basicServer.js

3. Step 3: Test the Server with Postman:

   • Open Postman.

   • Send a GET request to http://localhost:3000.

   • Inspect the response body (JSON format) and headers.

4. Step 4: Test with a Browser:

   • Open a browser and visit http://localhost:3000.

   • Observe the output as JSON in the browser window.
