Angular Hacks Every Developer Should Know

Angular is a powerful framework, but sometimes, you need clever tricks to optimize performance, improve maintainability, and enhance the developer experience. Here are some essential Angular hacks to boost your productivity.

1. Use Signals for Reactive State Management (Angular 16+)

With the introduction of Signals in Angular 16, managing state has become easier and more performant. Instead of using services with RxJS, leverage signals for better reactivity.

import { signal, computed } from '@angular/core';
class CounterComponent {
  count = signal(0);
  doubleCount = computed(() => this.count() * 2);
  increment() {
    this.count.set(this.count() + 1);
  }
}

Why?

• Reduces boilerplate
• Improves performance by reducing unnecessary re-renders

2. Lazy Load Modules Dynamically

Instead of loading all modules upfront, dynamically load them when needed to boost performance.

this.router.navigateByUrl('/feature', { skipLocationChange: true })
  .then(() => this.router.navigate(['/feature']));

Why?

• Reduces initial bundle size
