Express.js - Handling POST Requests with Body Data


In this tutorial, we will see how to handle POST requests with body data in Express.js and setting up a form, parsing form data and sending responses. POST requests are commonly used to submit data to a server, such as through a form or API.

Set Up the Express.js Server

Create a file index.js inside the my-app folder and add the following code.

index.js

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

// Middleware to parse URL-encoded data
app.use(express.urlencoded({ extended: true }));

// Route to serve a simple form
app.get('/', (req, res) => {
    res.send(`
        <form method="POST" action="/submit">
            <input type="text" name="name" placeholder="Enter your name" required>
            <button type="submit">Submit</button>
        </form>
    `);
});

// Handle POST request at /submit
app.post('/submit', (req, res) => {
    const name = req.body.name; // Accessing the name field from the request body
    res.send(`Hello, ${name}!`);
});

const PORT = 5000;
app.listen(PORT, () => {
    console.log(`Server is running at http://localhost:${PORT}`);
});

Run the Server

Run the server using the command given below.

node index.js
D:\my-app>node index.js
Server is running on http://localhost:5000

Output

Express Handle Post Request Form Output Express Handle Post Request Submit output
