Why?

UI complexity drastically increased:

• Multiple Server Responses
• Pushed Data (WS, SSE)
• Handle Optimistic Updates
• Cached Data (IndexedDB, localStorage)
• Fontend Routing
• UI Animations & Interactions

No Silver Bullet

NgRx Pattern Evolution

Why Angular?

Unidirectional Data Flow

Redux Principle

• Single source of truth: The whole state stored in object tree => Store
• State is readonly: To change state emit => Actions
• Pure functions: Changes are controlled by pure functions with specific signature => Reducers

Overall, NgRx embrace RxJs in order to streamline (no pun intended) & simplify the Redux architecture

Interests & Advantages

• Centralized & Immutable State
• Performance
• Testability
• Tooling & Ecosystem
