This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The Response() constructor creates a new Response object.

Syntax

var myResponse = new Response(body, init);

Parameters

body Optional
An object defining a body for the response. This can be one of:
init Optional
An options object containing any custom settings that you want to apply to the response. The possible options are:
  • status: The status code for the reponse, e.g., 200.
  • statusText: The status message associated with the staus code, e.g., OK.
  • headers: Any headers you want to add to your response, contained within a Headers object or object literal of ByteString key/value pairs (see HTTP headers for a reference).

Example

In our Fetch Response example (see Fetch Response live) we create a new Response object using the constructor, passing it a new Blob as a body, and an init object containing a custom status and statusText:

var myBlob = new Blob();
var init = { "status" : 200 , "statusText" : "SuperSmashingGreat!" };
var myResponse = new Response(myBlob,init);
