Never Call detectChanges() Again 😱 | Angular Signals + OnPush
Tired of Angular checking every single component whenever something happens — clicks, HTTP calls, or even timers? 🤯
That’s the Default change detection strategy. But with ChangeDetectionStrategy.OnPush, Angular updates your component only when you tell it to. Sounds powerful, but also a bit… manual.
Here’s the magic: with Angular Signals, you don’t need to call detectChanges() anymore. Signals automatically mark your OnPush component for update whenever their value changes — giving you the perfect balance of manual control + automatic updates.
In this video, you’ll learn:
✅ How Angular’s change detection really works
✅ Why OnPush makes your app faster
✅ How signals integrate with OnPush to update your UI automatically
✅ Best practices for building blazing fast Angular apps ⚡
By the end, you’ll never look at change detection the same way again.
