How to use mv3 background service workers?

[z0ccc]

Hi,

The in mv2 background scripts are declared like this:

  "background": {
    "scripts": [
      "browser-polyfill.js",
      "background.js"
    ]
  },

But mv3 only allows a single service worker like this:

  "background": {
    "service_worker": "background.js"
  },

How would use both "browser-polyfill.js" and "background.js" as service workers in mv3?

Thanks

in top of background.js
insert
importScripts("path/to/browser-polyfill.js");

Duplicate of #363. We should indeed document how importScripts can be used.

but declarativeNetRequest not support yet...

What do you mean by that? Even if DNR is not in the polyfill source, the polyfill will just forward the API access requests to the underlying APIs.

it just means I waiting for DNR support
I have a plan to use Dynamic to replace blocking on webRequest.onBeforeRequest
you mean.. there's another way to do like this??
