What is the best strategy for updating data only when necessary?

1

In an application with React Native , using Redux and Redux-Persist , what is the best way to identify that content needs to be updated?

In my case, I have an application that makes some requests on start up. When I enabled redux-persist I started to avoid the request if it had already been done at another time. But I have no idea how best to now identify whether or not to release the request again to update the data stored by redux-persist .

I read about using ETags and Last-Modified , but does that imply implementing this in the correct API too?

Any guidance to have this functionality implemented in the right way?
