A focused reference for Angular's dependency injection system that covers both modern patterns like the inject() function and traditional constructor injection. You get practical examples for common scenarios like hierarchical injectors, InjectionTokens, and factory providers, plus the decorators you need to know like @Optional and @SkipSelf. The guidance is clearly oriented toward Angular 21's functional approach while still covering the older patterns you'll encounter in existing codebases. If you're constantly looking up the syntax for multi providers or can't remember how forwardRef works, this consolidates the essentials. The examples are concise and ready to adapt, which beats scanning through official docs when you just need to wire up a service correctly.
