ExpressJS request.params and request.body empty

Trying to send a simple post request, the body property is empty object {}. Anyone knows why?

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

app.set('port', process.env.PORT)

// Support JSON-encoded and encoded bodies.
app.use(bodyParser.json())
app.use(bodyParser.urlencoded({ extended: true }))

app.post('/api/' + APIVersion.latest() + '/post-job', (req, res) => {
  console.log(req.body)
  res.json({ hey: 'hey' })
})

// Start the server.
app.listen(app.get('port'), err => {
  if (err) {
    return console.log('There was an error', err)
  }

  console.log(`Server running on port ${app.get('port')}`)
})

If req.body isn't being populated, you'll need to check how you are sending your POST request, since req.body is completely separate from the URL. If it's in an HTML form:

<form action="/person" method="POST">
  <input name="firstName" type="text">
  <button>Submit</button>
</form>

If you're sending your requests through a different avenue, you'll have to check the documentation for that API.

req.params is empty because your route doesn't specify any.

In Express, params refers to the route/url parameters. For example, if you wanted to have a route that allowed you to dynamically specify a user's last name, you may do:

app.get('/users/:last/info', (req, res) => {
    // ....
})

This would give the route a parameter of last, accessible by req.params.last.

req.params holds the route params, e.g. for /users/:id:

GET /users/123
req.params.id = 123

You want to access req.query, if you requested /api/v1/post-job?test=value, or the body itself in case you posted any.
