Mastering Angular Signals — the Angular v22 Edition is here

Quick but important one: Mastering Angular Signals — Angular v22 Edition is now live.

This isn't a typo fix. Angular started the Signals journey back in 2023, and in v22 the reactive toolkit is finally complete — the APIs that were still experimental are now stable, and new apps run zoneless with OnPush by default.

What's new in this edition

• Signal Forms — type-safe, declarative forms with no ControlValueAccessor boilerplate
• resource() / rxResource() / httpResource() — async data (loading, errors, refetch) without the RxJS plumbing
• linkedSignal() — writable derived state
• @Service() + injectAsync() — lazy, code-split services
• Angular Aria — headless, accessible UI primitives
• Zoneless + OnPush by default — change detection runs when a signal changes, not on every tick
• A brand-new RxJS/NgRx → Signals migration — a real-time dashboard moved off tangled streams and a store, piece by piece. Not a rewrite. A path.

The clearest way to feel the difference: async data went from this 👇

A tangled BehaviorSubject + switchMap + catchError + finalize chain…
…to a single httpResource(() => \/api/${city()}`)with.value(), .isLoading(), and .error()` built in.
