I just updated my long-running Angular HttpClient tutorial for Angular 21.
This guide covers:
- standalone components
- Signals
- provideHttpClient()
- functional interceptors
- loading/error states
- modern @if and @for syntax
It’s a full step-by-step tutorial with working examples and production-ready patterns.
Would love feedback from the Angular community.
