Скачать или смотреть 5 Angular Mistakes That Kill Performance (And How Signals Fix Them)

Is your Angular application feeling sluggish? Are you tangled in a web of subscriptions and complex state management? As a Google Developer Expert in Angular, I see developers repeating the same performance-killing mistakes. The good news? The future of Angular provides a powerful solution: Signals.

In this video, I break down the 5 most common mistakes holding your applications back, from inefficient change detection with Zone.js to convoluted state management with RxJS. More importantly, I'll show you the modern, elegant solutions using Angular Signals, `computed`, and `effect` that will make your code faster, cleaner, and ready for the future.

This isn't just about a new feature; it's about shifting your mindset to build next-generation Angular apps.

Key Topics Covered:

💡 *Mistake #1: The "Change Detection Everything" Mindset*
The problem with relying on Zone.js for everything.
The Solution: Fine-grained reactivity with Signals for surgical precision.

💡 *Mistake #2: Overly Complex State Management*
The old way: Using BehaviorSubject and the async pipe for simple tasks.
The Solution: The elegance and simplicity of `signal()` in a service.

💡 *Mistake #3: Tangled Logic for Derived State*
The old way: Using `combineLatest` and creating complex, hard-to-read streams.
The Solution: Effortless, memoized derived state with `computed()`.

💡 *Mistake #4: Misplacing Side Effects*
The danger of putting logic inside `.subscribe()` (The "Pyramid of Doom").
The Solution: Clean, predictable, and auto-tracking side effects with `effect()`.

💡 *Mistake #5: Sticking to Old Habits*
Why "but it works" is a dangerous trap.
Why embracing Signals is essential for your future as an Angular developer.
