Angular DI can become complex as apps scale. This Skill teaches using inject(), injection tokens, and providers to design flexible, testable architectures.
Install Angular and import DI APIs. Create a token and provide at the desired scope, then inject using inject(Token) in a class. Example: create an API_URL InjectionToken and provide { provide: API_URL, useValue: 'https://api.example.com' } at root, then private apiUrl = inject(API_URL);

Use the inject() function to retrieve Angular dependencies directly in class properties or functional code. It replaces constructor-based injection, offering a flexible way to access injectables in components and services.
Create an InjectionToken to represent runtime-configurable dependencies, then configure providers using useValue or useFactory. This decouples interface implementation from the token definition.
Manage provider scopes by configuring injectables at root, component, or route levels. Hierarchical DI patterns allow modular apps to share or isolate service instances across different injector trees.
Yes, apply DI options like optional, self, skipSelf, and host directly within the inject() call. These options control dependency resolution behavior for complex service architectures.
Yes, Angular v20+ supports multi-providers for registering multiple values to a single token. Environment injectors further enable advanced dependency injection patterns outside standard component hierarchies.
