Note: if you want to skip history behind this, and just looking for final result see: rx-react-container
When I just started using RxJS with React, I was subscribing to observables in componentDidMount and disposing subscriptions at componentWillUnmount.
But, soon I realised that it is not fun to do all that subscriptions(that are just updating property in component state) manually, and written mixin for this...
Later I have rewritten it as "high order component" and added possibility to pass also obsarvers that will receive events from component.
