While a precaching service worker can grossly improve the performance of a SPA, it definitely doesn't improve the speed of development when introduced between the dev's browser and the app to be debugged.

What are you trying to tell us here?

@petergriffin That I spent most of today trying to figure out why my changes aren't showing on the frontend.
What I was forgetting is that I spent yesterday setting up a service worker to cache all pages because according to my calculations live load would fry the server otherwise.

I have a setup where in production mode the SW caches normally and in development it doesn't cache at all
