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.

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.
