req-body-parser

A lightweight JSON body parser middleware for Express.
Works similarly to express.json() but gives you full control with minimal dependencies.

Installation & Usage

// Install the package first:
npm install req-body-parser

const express = require('express');
const reqBodyParser = require('req-body-parser'); // require from npm

const app = express();

/**
 * Use the middleware 
 */

app.use(reqBodyParser());


// Example POST route
app.post('/signup', (req, res) => {
  // req.body now contains parsed JSON
  const username = req.body.username;

  res.json({ username });
  console.log(username);
});

// Start server
app.listen(3000, () => {
  console.log('Server running on port 3000');
});
