What problem does it solve?

This Skill simplifies and clarifies the implementation of Angular's Dependency Injection system, enabling developers to build more modular, testable, and maintainable applications.

Core Features & Use Cases

• Modern Injection: Utilize the inject() function for cleaner service and dependency access.
• Provider Configuration: Learn to configure providers at various levels (root, component, route) for precise control over dependency lifecycles.
• Injection Tokens: Create and use InjectionToken for custom configuration and abstract dependencies.
• Provider Types: Understand and implement useClass, useValue, useFactory, and useExisting for flexible dependency provision.
• Advanced Patterns: Explore multi-providers, app initializers, environment injectors, and DI in testing.
• Use Case: When building a complex Angular application, you need to manage the lifecycle and provision of services like authentication, user data, and configuration across different components and modules efficiently.

Quick Start

Use the angular-di skill to demonstrate how to inject the HttpClient service into an Angular component using the inject() function.
