This is a comprehensive reference for Angular 21 directive patterns, covering attribute directives, structural directives, and the newer directive composition API. You'll want this when building reusable DOM behaviors or working with Angular's hostDirectives feature. The examples are practical and show both traditional decorators and the newer signal-based inputs. The code snippets lean heavily on best practices like using Renderer2 for DOM manipulation and keeping directives focused on single responsibilities. It's current for Angular 21 and includes the modern control flow syntax, though if you're still on older versions you'll need to mentally translate some of the examples back to NgModule patterns.
