Response: Response() constructor

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since March 2017.

Note: This feature is available in Web Workers.

The Response() constructor creates a new Response object.

Syntax

new Response()
new Response(body)
new Response(body, options)

Parameters

body Optional

An object defining a body for the response. This can be null (which is the default value), or one of:

options Optional

An options object containing any custom settings that you want to apply to the response, or an empty object (which is the default value). The possible options are:

status: The status code for the response. The default value is 200.
statusText: The status message associated with the status code, such as "OK". The default value is "".
headers: Any headers you want to add to your response, contained within a Headers object or object literal of String key/value pairs (see HTTP headers for a reference). By default this is empty.

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:

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