ssl - Can you use a service worker with a self-signed certificate?

Question

I have developer server that are used for testing. They have SSL self-signed certificates, which allow us to test the web application over HTTPS, but with prominent warnings that the certificates are not verifiable.

That's fine, but I have a Service Worker that throws an error with the navigator.serviceWorker.register

SecurityError: Failed to register a ServiceWorker: An SSL certificate error occurred when fetching the script.

How do I use a Service Worker with an intranet testing server which has a self-signed certificate?

Answer 1

As an alternative to using self-signed certificates, you can launch Chrome or Firefox such that it pretends certain domains are secure. For example, using Chrome on a Mac, you can launch it using:

/Applications/Google Chrome Canary.app/Contents/MacOS/Google Chrome --user-data-dir=/tmp/foo --unsafely-treat-insecure-origin-as-secure=http://www.your.site

Service workers should then work from http://www.your.site.

Edit: Changed --unsafety-... to --unsafely-...
