Subject, BehaviorSubject, and ReplaySubject

Angular’s reactive world revolves around Subjects, but the star is often the BehaviorSubject — why? Because it always starts with a value, and when you subscribe, you immediately get the latest emission (like receiving the current issue of a magazine). Meanwhile, ReplaySubject lets you go further by replaying multiple past values (no default), and a plain Subject is just “live only” — no past, no future. Let’s dig into when and why to use each.

Serverless functions in Nuxt: backend power without a backend

Serverless functions are tiny pieces of code that run on demand in the cloud. You don’t provision servers or infrastructure, or write scaling rules. Cloud providers handle the underlying infrastructure, automatically scaling resources based on demand. They’re perfect for lightweight APIs, form handlers, webhooks, simple auth endpoints, and glue code.

Signals + HTTP = httpResource [Tutorial]

Angular 19.2 rolls out httpResource — an experimental, signal-friendly layer over HttpClient that lets you fetch data reactively. Instead of juggling Observables and state flags, httpResource gives you built-in signals like isLoading() and hasValue(), and it automatically re-fires requests when dependent signals (e.g. page number, query) change.
