Answer 1

You need body-parser that will create body object for you in your request.
To do that npm install body-parser

var bodyParser = require('body-parser')//add this

app.use(bodyParser())//add this before any route or before using req.body

app.use((req, res) => {
  console.log(req.body); // this is what you want           

  res.on("finish", () => {

    console.log(res);

  });

});
