Bringing Observable Data to React
summary
Built a small library called parse-plus-react that wires Rx-style observables into React by adding an observe lifecycle where subscriptions are a function of state. Subscriptions auto-unsubscribe to avoid leaks, batch identical Ajax queries with caching, and let components rerender from things like user pointers or window-dimension observables. The prototype ships and runs (used for ~5 months, demoed at F8), and the code shows measurable simplification of async and continuously changing data handling.
