Fetch: The Response object

The Response Object returned by a fetch() call contains all the information about the request and the response of the network request.



Accessing the headers property on the response object gives you the ability to look into the HTTP headers returned by the request:

fetch('./file.json').then(response => {

Request headers for fetch


This property is an integer number representing the HTTP response status.

  • 101, 204, 205, or 304 is a null body status
  • 200 to 299, inclusive, is an OK status (success)
  • 301, 302, 303, 307, or 308 is a redirect
fetch('./file.json').then(response => console.log(response.status))


statusText is a property representing the status message of the response. If the request is successful, the status is OK.

fetch('./file.json').then(response => console.log(response.statusText))


url represents the full URL of the property that we fetched.

fetch('./file.json').then(response => console.log(response.url))
