Simplifying deep angular forms with di equipped custom components
summary
Claims that dependency injection can replace input drilling for nested forms by letting child components inject(FormGroupName) or ControlContainer and obtain typed FormGroup/FormArray. Demonstrates using the inject method with optional and skipSelf/host flags, an injection token composition, and strictly typed forms generics. Builds drop‑in elements like a reset button component and loaders that bind to the injected form or control, and shows them working in a deep, reusable nested form demo.
