Hola developers and learners 👋👋!! We are going to start a new blog series on Chrome Developer Tools. As a web developer, you know that having the right tools can make all the difference when it comes to building high-quality, efficient websites. But fear not! Chrome DevTools Elements section is here to save the day, like a superhero swooping in to solve all your web development woes 🦹.

Read the documentation https://developer.chrome.com/docs/extensions/. Build an MV3 for each API. File issues https://github.com/GoogleChrome/developer.chrome.com when you find inaccurate content.

where that is not what is really going on, because Chrome and Chromium browsers do not support capturing system audio. At best the audio captured is the tab audio. Try to capture the system audio produced by window.speechSynthesis.speak() and see what happens, see https://github.com/GoogleChrome/developer.chrome.com/issues/3957 https://github.com/GoogleChrome/developer.chrome.com/pull/3947#issuecomment-1274250421

Keep in mind that getDisplayMedia() does not capture all audio output to speaker or headphones, e.g., does not capture window.speechSynthesis.speak() output, which is not output via the Tab audio, see https://github.com/GoogleChrome/developer.chrome.com/issues/3957.

Yep, they just updated when CWS stops accepting MV2 updates to January 2024: https://github.com/GoogleChrome/developer.chrome.com/pull/38...

Here you go persistent-serviceworker.

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.

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.

Yes, it is possible to keep an extension or non-extension ServiceWorker persistent, active indefinitely https://github.com/guest271314/persistent-serviceworker.

If you host the HTML for and use "web_accessible_resources" in manifest.json the </code> can communicate directly with MV3 <code>ServiceWorker</code>. </p> <p>To keep MV3 <code>ServiceWorker</code> persistent see <a href="https://github.com/guest271314/persistent-serviceworker">https://github.com/guest271314/persistent-serviceworker</a>.</p> </div>

I utilize "web_accessible_resources" with an , where chrome.* API's are exposed, and does not become inactive.
