A step-by-step guide to building a real-time scoreboard using Server-Sent Events (SSE) with Angular on the frontend and NestJS on the backend, organized in an Nx monorepo. Covers setting up the NestJS SSE endpoint using the @Sse decorator with RxJS observables, creating an Angular service that consumes the EventSource API, and wiring up start/stop controls. Compares SSE to SignalR, noting SSE is one-directional but simpler for server-to-client streaming scenarios.
