Angular Component Communication: Complete Guide | @Input @Output EventEmitter & ViewChild

When I first started working with Angular, component communication was one of the most confusing aspects of the framework. I'd find myself passing data through multiple levels of components, creating complex event chains, or resorting to global state...

Angular State Management with RxJS: Complete Guide | Observables, Subjects & BehaviorSubjects

When I first started building Angular applications, I thought I needed Redux or NgRx for state management. Then I realized that Angular is built on RxJS, and I could manage state effectively using just Observables, Subjects, and BehaviorSubjects. Thi...

Part 7: rxResource() — When Native Features Validate Your Architecture

A few years ago, some very smart developers on my team solved a problem Angular hadn't addressed yet: how do you handle async state cleanly across an enterprise application? Their answer was elegant. A ResponseService that wraps any observable into a...

Part 6: linkedSignal() — The Cascade That Finally Made Sense

Let's be honest — I've written allowSignalWrites: true more times than I'd like to admit. Every time, it felt like a hack. Every time, I told myself I'd come back and fix it properly. Then last week, I actually did come back. There it was — code I de...

Part 5: Putting It All Together — The Counter Dashboard

Few weeks ago, I couldn't explain why I'd choose a signal over a BehaviorSubject. Today, I just built an entire component without a single subscribe(), takeUntil(), or ngOnDestroy(). No Subjects. No lifecycle hook juggling. Just signals, computed val...

Part 4: input(), output(), model() — The Day I Mass-Deleted ReplaySubject

I need to show you something embarrassing. This is a pattern I've written in almost every component that needed reactive inputs: private metricInSubject = new ReplaySubject<DashboardMetricWithVisualization>(1); @Input() set dashboardMetricWithVisuali...

Part 3: effect() — The Escape Hatch I Keep Reaching For (And Shouldn't)

I have a confession. When I first learned about effect(), I thought: "Oh, this is just subscribe() with a nicer API." And I started using it everywhere. Signal changes? Effect. Need to do something? Effect. Want to compute a value? Eff— wait, no. Tha...

Part 2: computed() — The Day I Mass-Deleted combineLatest

Let me paint you a picture. My codebase has combineLatest everywhere. And I mean everywhere. Services combining streams. Components bundling observables for templates. Inputs converted to Subjects just so they can participate in the reactive party. H...

Part 1: signal() — From "Using" to Actually Understanding

I've been writing signals for months. Our Angular 19 codebase has them sprinkled throughout — signal inputs here, a computed() there. It works. But if you'd asked me last week why I'd choose a signal over a BehaviorSubject, I'd have given you a vague...
