There is an in-built middleware present in Express which can handle json/form data in an application.

How to do it?

We just have to write a simple line of code

For JSON data -

app.use(express.json())

For Form data

app.use(express.urlencoded())

What will happen after adding this ?

This will add a property body to request object, which contains all the data in the form of key-value pairs.

How to access data?

app.get('/',(request,response)=>{
   console.log(request.body);
})

This will give all the data whether it is JSON or Form data.

Happy Coding
