Angular’s resource and rxResource APIs with Input Signals with dynamic params

Angular’s evolution with signals has transformed how developers handle reactivity and API calls. If you’ve been exploring Angular 19 or later, you’ll love the flexibility and power of resource and rxResource.

In my latest video, I take a deep dive into using these features to manage dynamic API calls effortlessly.

What’s Inside the Video?

This video builds on a parent-child component interaction scenario where the postId is dynamically passed as an @Input() from the parent to the child. I demonstrate:

• Traditional Approach: Using @Input() decorators and the HttpClient for API calls.
• Modern Solution: Transitioning to input signals for cleaner and more reactive data flow.
• Dynamic API Calls: Using Angular’s resource and rxResource APIs with promises and Observables respectively.

Cheers!
