Parsing the HTTP request body

body-parser is a middleware function that parses the incoming request body and makes it available in the request object as request.body https://expressjs.com/en/resources/middleware/body-parser.html.

This module allows an application to parse the incoming request as:

• JSON
• Text
• Raw (buffer original incoming data)
• URL encoded form

The module supports automatic decompression of gzip and deflates encodings when the incoming request is compressed.

Getting ready

In this recipe, you will see how to use the body-parser NPM module to parse the content body sent from two different forms encoded in two different ways. Before you start, create a new package.json file with the following content:

{ 
    "dependencies": { 
        "body-parser": "1.18.2", 
        "express": "4.16.3" 
    } 
} 

Then, install the dependencies by opening a terminal and running:

npm install

Two forms will be displayed to the user, both of them will send data to our web server application encoded...
