You should install body-parser through npm-install. Now it comes as a separate middleware.

After that add following line in your app.js

var bodyParser = require('body-parser');app.use(bodyParser.json());app.use(bodyParser.urlencoded());// in latest body-parser use like below.app.use(bodyParser.urlencoded({ extended: true }));

It parses the post request as an object. You will get your variables in req.body.

In your post request handler.

app.post('/post',function(request,response){   console.log(request.body) //you will get your data in this as object.})

Edit 1

The answer above was for the question specifically asked, the OP was looking for the bodyParser(deprecated) which was not part of express anymore.

Since the title of the question is very generic and the answer doesn't include all aspects of form-data, I will put @StLia's answer as an edit.

Body-Parser Readme

This does not handle multipart bodies, due to their complex and typically large nature. For multipart bodies, you may be interested in the following modules:

• busboy andconnect-busboy
• multiparty andconnect-multiparty
• formidable
• multer

You can make use of express-formidable module to that.install 'express-formidable' by the following command

npm install express-formidable

the simple example is as follows

const express = require('express');const formidable = require('express-formidable'); var app = express(); app.use(formidable()); app.post('/upload', (req, res) => {  //req.fields contains non-file fields   //req.files contains files   res.send(JSON.stringify(req.fields));});

From the README of body-parser:

This does not handle multipart bodies, due to their complex and typically large nature.

The above is going to work with x-www-form-urlencoded and json but it will NOT work with any multipart. form-data is also multipart with the header multipart/form-data.

In case of form-data, your best solution would be to use express-formidable.
