This is your go-to for Angular v20+ projects where you want to work with Signals, Standalone Components, and Zoneless mode instead of the old zone.js patterns. It covers the modern reactive primitives (signal, computed, effect), the new signal-based input/output/model APIs, and SSR with incremental hydration. The skill draws a clear line between when to use Signals versus RxJS, which is genuinely helpful since the ecosystem is mid-transition. If you're still on AngularJS or stuck on an ancient Angular version you can't upgrade, this won't help you. But for greenfield projects or apps you can modernize, it's focused on the patterns that are actually stable now.
