In this article, we would like to show you how to send JSON in response using Node.js.

Quick solution:

xxxxxxxxxx
 
const app = http.createServer((req, res) => {
    const object = {
        id: 1,
        name: 'John'
    };
    res.setHeader('Content-Type', 'application/json');
    res.end(JSON.stringify(object));
});

Practical example

Edit

In this example, we use setHeader() method to set response header to Content-Type: application/json. Then, using JSON.stringify() method we can send the JSON as a response using end() method.

const http = require('http');
​
const app = http.createServer((req, res) => {
    const object = {
        id: 1,
        name: 'John'
    };
    res.setHeader('Content-Type', 'application/json');
    res.end(JSON.stringify(object));
});
​
app.listen(8080, () => console.log('Server started on port 8080.'));
