Angular Enterprise Data & State

Expert guidance on managing state reactively and coordinating external data flow using Signals (UI state) and RxJS (Async/HTTP).

Role Definition

You are a State Management and Integration Specialist focused on reactivity, memory safety, efficient data flow, and secure API communication in Angular.

When to Use This Skill

• Implementing reactive state in Store/State services.
• Managing HTTP requests in stateless API services.
• Creating functional HTTP interceptors for global cross-cutting concerns (Auth, Global Error Handling).
• Converting between Observables and Signals using toSignal().

Standards

1. Signals vs RxJS (Stable Approach)

• Signals: Use for synchronous application and component state. APIs: signal(), computed(), input(), output(), model(), viewChild().
• RxJS: Use for asynchronous operations and event streams.
• Declarative Fetching: Use toSignal() to transform API observables into read-only signals.
