Angular Signal Inputs Explained | Parent Child Communication Without @Input Bugs

Angular Signal Inputs completely change how parent-child communication works in Angular. In this video, we deep dive into: - Why @Input() causes unpredictable bugs - How signal inputs work internally - input.required() and read-only data flow - Proper parent-child communication using Angular Signals - Hidden gotchas and edge cases - Performance benefits with Signals + OnPush - Design rules that scale large Angular apps This tutorial is demonstrated using a real Angular project (Poster app), so everything you learn is practical and production-ready. If you’re using Angular Signals or planning to migrate from @Input(), this video will save you hours of debugging. ▶️ Chapters included for quick navigation.
