JSON text/plain

Seems that “Post JSON” don’t work. Because if body is string (and JSON is actually a string) polyfill sets header ‘content-type’ to ‘text/plain;charset=UTF-8’

But in docs:

fetch('/users', {
  method: 'POST',
  headers: {
    'Accept': 'application/json',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    name: 'Hubot',
    login: 'hubot',
  })
})

You seem to be sending a POST to another domain. Please familiarize yourself with CORS to learn what’s blocking you from changing the Content-Type of the request.

@mislav sorry, that was about server configuration. Fetch is a great way to write XHR 😃
