Can we work without Body-parser in Node js

Question

I don't understand why we need body-parser in an Express application, as we can get data without it. And what does it do actually and how?

Answer 1

To understand this question you first need to understand, how the request comes to your client

where URL specifies the server where you want to send the request too

The method specifies the HTTP Method like PUT, GET, POST, DELETE

The header provides metadata about your request 

The body says about the information you are requesting for

So when you get a request in this format to separate the body from the request you need body-parser and give it to the req.body
