Offline Plugin guidance apart from OFSC official documentation.

Summary:

Hello Folks,

I am working with OFSC from couple of months and I encountered one challenge to work with OFSC plugin which will be working as Offline using plugin framework and secure support of service-worker so I have tried to check for Official documentation available but seems in that document there is only plugin framework is explained and not exact information how we can work with service-worker to implement it as a part of plugin in OFSC. [I have tried with sample plugin - but it is not having exact information that I want to understand.]

So for a thoughtful information can anyone is having any dummy sample code available to understand the offline mode plugin scenario where OFSC properties are stored and handled using service worker and upon online it will sync with OFSC property and same thing for POST and PATCH request.
