Can't register a serviceWorker

[jcansdale]

I'd like to be able to register a service worker: navigator.serviceWorker.register('/sw.js');

Access to service workers is denied in this document origin.

Is looks like there is a function that can be called to override this, but I'm not sure where it needs to be called from: registerURLSchemeAsAllowingServiceWorkers("file");

According to this issue, this should be enabled by default from Electron v0.36.0: https://github.com/electron/electron/issues/2831

Is there any way to get this working with the current bits?

I've tried adding that code to server.js and preload.js and I'm still getting an error using ServiceWorkers. Seems like an Electron bug?

GET file:///projects/jam3npm/devtool/test/fixtures/service-worker.js net::ERR_INVALID_RESPONSE
undefined:1 Uncaught (in promise) DOMException: Failed to register a ServiceWorker: A bad HTTP response code (-1) was received when fetching the script.

See test here: https://github.com/Jam3/devtool/tree/test-service-worker

Looking at the Chromium C++ code: https://codereview.chromium.org/1191793003/diff/40001/Source/platform/weborigin/SchemeRegistry.cpp if (serviceWorkerSchemes.isEmpty()) { serviceWorkerSchemes.add("http"); serviceWorkerSchemes.add("https"); serviceWorkerSchemes.add("chrome-extension");

I wonder if: electron.protocol.registerServiceWorkerSchemes(['file:']);

...should use simply 'file'? This is very much a guess! :)

Thanks for looking into it!

Can you try 2.0.2? It should have a patch for this.

To update:

npm install devtool -g

Ok, nevermind. Error is still there
