Angular Http

This covers Angular's HttpClient for API calls, interceptors, and error handling in Angular 21. You get functional interceptors instead of the old class-based approach, plus new features like native fetch support and HttpContext tokens for per-request metadata. The examples show auth patterns, retry logic with backoff, and proper TypeScript typing for responses. Worth noting the migration path from deprecated class interceptors to the modern functional style, which is cleaner and works better with Angular's dependency injection. If you're building anything that talks to a backend in Angular, this has the patterns you'll actually use.
