NgRx provides Angular developers a framework for managing streams of data in a reactive way. Actions provide an expressive way to manage state and trigger state changes, along with immutability enforced by reducers as pure functions, but that’s only the beginning. The real power of state management comes in two ways: selectors and side effects. Selectors provide simple, compose-able ways to get and derive data, while side effects isolate business logic. This talk shows you have to take more advantage of these reactive streams in your Angular application to retrieve data and perform tasks.
