The components we build for our web applications often contain state. Connecting components can lead to sharing mutable state: this is difficult to manage and leads to inconsistency. What if we have one place where we mutate the state and let messages do the rest? ngrx/store is an implementation of Redux for Angular, using RxJS, that brings this powerful pattern into the Angular world.
In this article, I will introduce the problem of shared mutable state and show how you can solve this using the ngrx/store library to bring the one-way data flow architecture to your Angular 2 apps. Along the way, we’ll build an example app that allows a user to search for videos using the YouTube API.
