Body Parsing

By default, Express doesn't know how to handle the data sent in a POST request body. You must use middleware to parse it.

1. Parsing JSON Data

Essential for modern client-side apps sending JSON.

app.use(express.json());

      app.post('/api/data', (req, res) => {
        console.log(req.body); // { name: 'Pradeep', age: 25 }
        res.json({ status: 'Success' });
      });

2. Parsing Form Data

Used for traditional HTML form submissions.

app.use(express.urlencoded({ extended: false }));

      app.post('/submit-form', (req, res) => {
        // Access data as req.body.fieldName
        res.send('Form received!');
      });

3. Parsing Text or Raw Data

Occasionally, you might need to handle raw text or binary data.

app.use(express.text());
      app.use(express.raw());
