Why should I use inject() instead of constructor injection?

The inject() function provides better type safety, allows for injection in functional contexts outside of classes, and results in cleaner, more readable code in modern Angular applications.

Can this skill help with testing Angular services?

Yes, by providing patterns for useClass and useValue, it simplifies the process of overriding and mocking dependencies during unit and integration testing.

Can I use this for asynchronous application initialization?

Yes, it includes patterns for using provideAppInitializer to execute asynchronous logic and resolve dependencies before the application completes its bootstrap process.

Does it support the latest Angular versions?

Yes, it is specifically designed for Angular v20+ and focuses on standalone component patterns and modern DI APIs.

How do I handle multiple values for the same token?

The skill provides detailed implementation guides for using Multi-providers, which are essential for features like HTTP interceptors and custom validators.
