Request: referrer property

The referrer read-only property of the Request interface is set by the user agent to be the referrer of the Request. (e.g., client, no-referrer, or a URL.)

Note: If referrer's value is no-referrer, it returns an empty string.

Value

A string representing the request's referrer.

Examples

In the following snippet, we create a new request using the Request() constructor (for an image file in the same directory as the script), then save the request referrer in a variable:

js

const myRequest = new Request("flowers.jpg");
const myReferrer = myRequest.referrer; // returns "about:client" by default
