I didn't use any library. Seemed easy enough to just create a few helpers. I rely on Firebase completely for the data. Since Firebase already keeps a local client cache as well as an offline cache, I didn't see any need to maintain separate state in React -- outside of the HOC components. They subscribe automatically to the data when the component mounts and unsubscribe when the component is destroyed. Any changes, whether from within the app, from the server, or from another instance of the app; have changes synced everywhere for free. The only local state I have at the app level is state that doesn't get stored in the DB. Here's the helper HOC I created for it: https://github.com/brennancheung/wowzrs/blob/master/src/app/core/FSQuery.js https://github.com/brennancheung/wowzrs/blob/master/src/app/... And an example of it being used as a render prop: https://github.com/brennancheung/wowzrs/blob/master/src/app/components/actions/ActionsList.js#L34 https://github.com/brennancheung/wowzrs/blob/master/src/app/... And another as an HOC: https://github.com/brennancheung/wowzrs/blob/master/src/app/components/actions/ActionsForToday.js#L33 https://github.com/brennancheung/wowzrs/blob/master/src/app/... And here's a mutation: https://github.com/brennancheung/wowzrs/blob/master/src/app/components/actions/AddAction.js#L14 https://github.com/brennancheung/wowzrs/blob/master/src/app/... The HOC's make it so you can create just plain stateless functional components and not have to worry about componentDidMount.
