State management is complex and time-consuming.
On large applications, it becomes very difficult to maintain state. The redux pattern helps resolve this issue.

ngrx is the redux pattern implemented for Angular . View on GitHub.

  • Easy state management
  • Better tooling and debugging
  • Simpler applications to build
  • Increased performance
  • Code that is easy to test

The three principles of the redux pattern:

  1. The entire state of the application is represented in a single JavaScript object called a store.
  2. The store is acted upon using special functions called reducers. 
  3. State is immutable and reducers are the only part of the application that can change state.
