I recently hosted a website for events on Firebase hosting and have not been able to see what will be the monthly usage of the app. I have a service worker that caches the files of the website for faster subsequent visits and offline capability. My question is, can the service worker reduce the monthly firebase usage of the website as the website will be loaded most of the times from the cache and not from a request to firebase? This is purely my way of thinking so correct me if I am wrong.
Yes, this will reduce the usage.
The usage is displayed in the firebase console => Hosting => Usage => Downloads (Bytes sent)
