Response: url property

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 url read-only property of the Response interface contains the URL of the response. The value of the url property will be the final URL obtained after any redirects.

Value

A string.

Examples

In our Fetch Response example (see Fetch Response live) we create a new Request object using the Request() constructor, passing it a JPG path. We then fetch this request using fetch(), extract a blob from the response using Response.blob, create an object URL out of it using URL.createObjectURL(), and display this in an <img>.

Note that at the top of the fetch() block we log the response URL to the console.

js
const myImage = document.querySelector("img");

const myRequest = new Request("flowers.jpg");

fetch(myRequest)
  .then((response) => {
    console.log("response.url =", response.url); // response.url = https://mdn.github.io/dom-examples/fetch/fetch-response/flowers.jpg
    return response.blob();
  })
  .then((myBlob) => {
    const objectURL = URL.createObjectURL(myBlob);
    myImage.src = objectURL;
  });
