--- name: angular-state-management description: "Master modern Angular state management with Signals, NgRx, and RxJS. Use when setting up global state, managing component stores, choosing between state solutions, or migrating from legacy patterns." risk: safe source: self date_added: "2026-02-27" --- # Angular State Management Comprehensive guide to modern Angular state management patterns, from Signal-based local state to global stores and server state synchronization. ## Detailed Guide Read [the detailed guide](references/detailed-guide.md) before executing this skill. It retains the complete procedure and reference material. Treat its safety, prerequisites, and validation requirements as mandatory. For focused work, load the relevant sections; for end-to-end work, read the guide completely. ## When to Use This Skill - Setting up global state management in Angular - Choosing between Signals, NgRx, or Akita - Managing component-level stores - Implementing optimistic updates - Debugging state-related issues - Migrating from legacy state patterns ## Do Not Use This Skill When - The task is unrelated to Angular state management - You need React state management → use `react-state-management` --- ## Limitations - Use this skill only when the task clearly matches the scope described above. - Do not treat the output as a substitute for environment-specific validation, testing, or expert review. - Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing. ## Example For a shared cart counter, use a private writable signal and a public read-only signal. For remote cart writes, keep authorization on the server and test two overlapping updates before adding optimistic rollback.
