Dependency Injection

Injectable services, lifetimes and scopes, typed keys, and providers.

• Inject Services

  Make a class injectable, take dependencies in the constructor, and keep logic out of handlers.

• Lifetimes and Scopes

  How long an instance lives, and why each platform event gets its own container.

• Typed Keys and Providers

  Inject values and interfaces (not just classes) with TypedInjectionKey and @Provider.
