angular-signals

Signal-based reactive state management for Angular v20+ with synchronous, fine-grained reactivity. Signals are Angular's reactive primitive for state management. They provide synchronous, fine-grained reactivity. Effect rules: For advanced patterns including resource(), see references/signal-patterns.md . - Core APIs include signal() for writable state, computed() for derived state, linkedSignal() for dependent state with automatic reset, and effect() for side effects - Integrates with RxJS via toSignal() and toObservable() for converting between observables and signals - Supports custom equality functions, untracked reads to break dependencies, and read-only signal exposure via asReadonly() - Typical patterns include component state management with filtered/derived data, service-level state with public read-only signals, and HTTP request handling with optional initial values - Run in injection context (constructor or with runInInjectionContext ) - Automatically cleaned up when component destroys
