Redux has a number of tools and middleware available in its ecosystem to facilitate elegant app development.
Redux DevTools - a tool that displays a linear timeline of actions that have interacted with its store. Allows for replaying actions and error handling
redux-thunk - middleware that enables lazy evaluation of actions
redux-observable - an RxJS-based model for handling side-effects on action streams.
*ng2-redux-router - reactive glue between the Angular router and your redux store.
@ngrx provides most of its Redux implementation through the ngrx/store module. Other modules are available for better integration and development.
