title: when to run saga's in react-native?
body: <p>When using redux-saga with react-native what is the best practice in terms of when you run/stop sagas?  That is should the approach be:</p>
  
  <p>a) run all sagas straight in one hit when starting the app from early in the app cycle (like I see in the short redux-saga examples), or</p>
  
  <p>b) start specific sagas in the "componentDidMount" for a specific "screen/page" within that component (e.g. showListContainer.js)</p>
  
  <p>Also if the saga is say waiting for myList updates from external sources (firebase's firestore in this case) then this would affect the choice above then no?   That is for option a) above what happens as updates come in here? Or is the concept that the saga would take updates and update the redux store contents, hence in terms of the specific page displaying the updates that would be separate/decoupled?  So I guess:</p>
  
  <p>Question 2: Is the concept of react-native use of redux-saga to have the "saga to redux store" work together, and then decouple the react-native visual updates "redux store to react-native updates"</p>
