How can I make an http request in the service worker Chrome extension?

Question

I am trying to develop a Chrome extension. Now background scripts are replaced by service workers in manifest v3. How can I make an http request in the service worker?

Answer 1

Use this in your service worker:

fetch('http://example.com/movies.json')
  .then((response) => response.json())
  .then((data) => console.log(data));

Don't forget to set proper permissions in the manifest file:

  "host_permissions": [
    "http://example.com/"
  ],
