Discussion: Any examples on stores subscribing to other stores? #116

Closed thegalah closed 5 years ago

In the readme under "Data Flows" it is mentioned that stores can subscribe to other stores. However my understanding of resub is that only ComponentBase components are able to subscribe to stores. Are there any examples on how this can be achieved?

I'm actually not sure there are any examples. Just call store.subscribe(callbackFunc, keyIfAny) and it'll call your function back. Very simple pub-sub model for manual subscriptions to stores.

(FWIW, I use this model all the time in my private projects -- stores subscribing to other stores and adding meta-value on top of the other store's more-raw data.) Just make sure that you unsubscribe if/when you're done with the data or the store will call you back forever. :)
