Covers Angular v20+ dependency injection patterns with modern inject() syntax instead of constructor injection. Shows provider configuration at root, component, and route levels, plus injection tokens for configuration and multi-providers for collecting services. Includes practical examples of optional injection, scoped services, app initializers, and environment injectors. Good reference when you need to understand DI hierarchy or set up complex service architecture. The multi-provider examples are especially useful for plugin systems or collecting validators.
