Raw Body Parsing Approach

You can directly access and parse the raw request body. This gives you more control over the parsing process.

Example: Below is the code example of raw body parsing

Javascript

const express = require('express'); 
const app = express(); 
  
app.use((req, res, next) => { 
    let data = ''; 
    req.setEncoding('utf8'); 
    req.on('data', (chunk) => { 
        data += chunk; 
    }); 
  
    req.on('end', () => { 
        req.body = data; 
        next(); 
    }); 
}); 
  
app.post('/api/rawdata', (req, res) => { 
    console.log('Received raw data:', req.body); 
    res.status(200) 
        .json( 
            { 
                message: 'Raw data received successfully.'
            } 
        ); 
}); 
  
const PORT = process.env.PORT || 3000; 
  
app.listen(PORT, () => { 
    console.log( 
        `Server is running on http://localhost:${PORT}` 
    ); 
});

This approach manually reads and concatenates chunks of the request body to give you control over the entire request payload and handle large payloads efficiently.
