NgRx provides Angular developers a framework for managing your application state 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. One of the real advantages of NgRx comes in the form of selectors. Selectors provide simple but powerful ways to efficiently get, derive, and compose view models for your application. This talk takes a deeper look at NgRx selectors, with examples and advanced features such as memoization and custom selectors.
