Express + Postman, req.body is empty

Try this

 // create application/json parser
    app.use(bodyParser.json());
    // parse various different custom JSON types as JSON
    app.use(bodyParser.json({ type: 'application/*+json' }));
    // parse some custom thing into a Buffer
    app.use(bodyParser.raw({ type: 'application/vnd.custom-type' }));
    // parse an HTML body into a string
    app.use(bodyParser.text({ type: 'text/html' }));
    // parse an text body into a string
    app.use(bodyParser.text({ type: 'text/plain' }));
    // create application/x-www-form-urlencoded parser
    app.use(bodyParser.urlencoded({ extended: false }));

AFAIK you need to use the Body-Parser : https://github.com/expressjs/body-parser

bodyParser = require('body-parser').json();
app.post('/itemSearch', bodyParser, function(req, res) {
  //var Keywords = req.body.Keywords;
  console.log("Yoooooo");
  console.log(req.headers);
  console.log(req.body);
  res.status(200).send("yay");
});

Then try with PostMan setting the body as raw json:

{
  "test": "yay"
}

After spending a few hours I realized need to change the Raw type in postman to JSON

I wanted to add an answer, as was seeming to have trouble getting sending as form-data to work, even if I was adding Content-Type: multipart/form-data to the Header (this was listed as correct header type in docs). I wonder if because using BodyParser in express, data has to come in as JSON raw. I swear I got form-data to work before, alas.

Here's how I was able to get req.body not to be empty:

1. Make sure in "Headers" tab, you have this key value pair setup:

Content-Type: application/json

Side note: interesting link to stack overflow article on all available header content type values.

2. In "Body" tab, make sure raw radio button is selected, and far right dropdown has JSON selected:

3. Now if I console log req.body in my express app, I see printed:
