Response()

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:

• Blob
• BufferSource
• FormData
• ReadableStream
• URLSearchParams
• USVString

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 status 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);
