My question is, Is it possible for the Users to acquire these changes without having to REINSTALL the PWA application?
I have a PWA application deployed in Production. The client already installed the deployed PWA application in their MOBILE devices and I want to DEPLOY another patch of updates in the PWA application in the HTTP server.
I would suggest to read this link explaining in detail how the SW Updates work.
Long story short, if you deploy a new app version, the new SW will be installed on the client's side (using a separate/dedicated install event) and then activated when the users navigates to an URL different from the PWA one.
There is also a built in service workers feature called "fail safe". Within at most 24H the SW checks if a newer version is available and, if so, attempts to update to it.
I wrote a PWA series and here a post about Service Workers and caching strategies if you want to read more.
Another simple way to update application is using workbox-window. You can detect updates in PWA and restart your application to get the last updates. For more detail, I suggest you read this link
