In my project I have such line of code
navigator.serviceWorker.register('{% static "js/firebase-messaging-sw.js" %}')
But if I launch my project not on localhost, I got an error Uncaught TypeError: Cannot read property 'register' of undefined

are you still trying to access static files on develepment server? Can you access on js/firebase-messaging-sw.js on browser? I think it is static file issue – marlonjd Feb 06 '20 at 17:06

Can you check on developer console on browser. On network tab it will show. Which address this trying to access ? It will show 404, 200 or 500. – marlonjd Feb 06 '20 at 17:13

@marlonjd - I can't see such response on network tab. Maybe because my script is in html body? – Headmaster Feb 06 '20 at 17:36

On localhost, can you see ? – marlonjd Feb 06 '20 at 17:38

I need to serve page over HTTPS or use localhost. Service workers require a Secure Context.
