Angular Reactive Data & State Best Practices

When to Use

• Designing or restructuring a store, state service, or facade (the client analogue of a data layer)
• Choosing a state approach: signals, RxJS services, NgRx Store, or NgRx Component Store
• Modeling state shape, normalizing collections, or keeping state immutable
• Writing selectors / derived state, or troubleshooting over-fetching, redundant requests, and re-render performance
• Implementing optimistic updates and handling server-side concurrency conflicts
• Persisting and hydrating state (localStorage/sessionStorage) with versioning
