How to keep a serviceworker (background.js) alive in a chrome extension

[AskJS] Do specification authors and implementers listen to developers in the field?
5 projects | /r/javascript | 29 Jan 2023

The ServiceWorker becoming inactive in 5 minutes per MV3 is a debacle. Workarounds exist and the code to implement keeping the ServiceWorker persistent, e.g., to stream live radio station from the ServiceWorker to the client winds up not saving any resources - we have to keep something running to keep the service worker running. You would be hard-pressed to count how many issues in the wild have been filed in multiple source code repositories just on that lack of functionality - for years now, e.g., Need help to understand and use this #2.
[AskJS] What are the worst case scenarios for programmatically setting arbitrary Web pages (Origins) as Client or WindowClient of a ServiceWorker?
6 projects | /r/javascript | 25 Dec 2022

There are workarounds which involve using an iframe https://github.com/guest271314/persistent-serviceworker/tree/main/chromium_extension_web_accessible_resources_iframe_message_event or window.open() https://github.com/guest271314/sw-transfer-stream or and offscreen document https://github.com/guest271314/offscreen-webrtc with WebRTC - however that involves loading an entire HTML document, and each has its own deficienfies - with all of the Window features that we do not really need just to transfer data between the Web page I have control of and the ServiceWorker I have control of.

One approach for your requirement is to append an iframe with src set to an HTML document listed in "web_accessible_resources" to an arbitrary document and use postMessage() from the Web page to the iframe, then from the iframe to the MV3 ServiceWorker, see https://github.com/guest271314/persistent-serviceworker/tree/main/chromium_extension_web_accessible_resources_iframe_message_event.

For-profit content blockers have teams of paid developers working on this (for examples see https://gitlab.com/groups/eyeo/adblockplus/abc/-/issues/?sort=created_date&state=all&first_page_size=20, https://gitlab.com/groups/adblockinc/-/issues/?sort=created_date&state=all&label_name%5B%5D=manifest%20v3&first_page_size=20, https://github.com/AdguardTeam/AdGuardMV3/issues), and I also see the need for not trivial infrastructure to manage patching the filter lists, something which is beyond what I can provide.
