Node JS Tutorial - Serving JSON Data

In this tutorial, we will learn how to serve JSON data to clients using Node.js.

Step 1: Create a Server in Node.js

Go to your project and open the index.js file. First, require the http package and write the following code:

var http = require('http'); 
var server = http.createServer(function(req,res) 
{ 
    res.writeHead(200,{'Content-Type':'application/json'}); 
    var student = { 
        name:"Jenifer", 
        email:"jenifer@gmail.com", 
        phone:"1234567890", 
        age:25. 
    }; 
    res.end(JSON.stringify(student)); 
});
server.listen(3000); 
console.log("Server is running on localhost:3000");

Step 2: Run the Server

Next, let's run the server. Go to the command prompt and execute the following command:

node index.js

The server is now running on localhost:3000. Open a web browser and navigate to localhost:3000. You should see the JSON data being served by the server.

That's it! You have successfully served JSON data to a client using Node.js. This is a fundamental concept in web development, and is used extensively in APIs and web applications.

By following these simple steps, you can easily serve JSON data to clients using Node.js.
