How to get request body in Node JS middle ware from multi-part form data?

I know it is easy to get the requested body using as follows:

app.post('/api', (req, res) => { conosle.log(req.body); })

But my question is different from above. Here is my index.js file (entry file).

const express = require('express');
const app = express();

const config = require('./config/config.js');

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

app.use((req, res, next) => {

  console.log(req.body); **// here I am not getting req.body**

  const routes_handler = require('./routes/index.js')(app, express, req);
  next();
});


app.listen(config.SERVER.PORT, () => {
  console.log("Server running at Port " + config.SERVER.PORT);
});

FYI, using the postman, I am passing request as form-data. and in the form, there is also a field as file type(picture). In handling the API part, I am using multer and also getting req.body as per required.

But I just want to know how can I get req.body in middleware block i.e. in 

 app.use((req, res, next) => {//HERE req.body })

Here is my POSTMAN simple request as follows:

Try to using body-parser. You can find an example code here from express.js

const app = require('express')()
const bodyParser = require('body-parser')
const multer = require('multer')

app.use(bodyParser.json())
app.use(bodyParser.urlencoded({ extended: true }))

app.use(multer.array(), (req, res, next) => {

  console.log(req.body);

  const routes_handler = require('./routes/index.js')(app, express, req);
  next();
});

simple make a middleware function like this :

const middleware = (req,res,next) =>{
     console.log(req.body);
     // all your multer logic here
}

and use it before your post request route like this..

app.post('/' , middleware , (req,res,next) =>{
// all your api logic here 
});

as body is only availabe in certain types of http requests including post ,put and not available in get requests so you wont get your console.log() in those requests.

Please use multer for getting form data 

var multer = require('multer');
var upload = multer();

app.use(upload.array());
