In this lesson, you will learn how to build an event-driven architecture that integrates NestJS on the backend and Next.js on the frontend using EventEmitter and Server-Sent Events (SSE).
By the end of the session, you will have created a full-fledged real-time system where NestJS generates and processes events, and Next.js instantly reacts to them in the interface. This approach is ideal for applications with live notifications, background processes, and dynamic UI updates.
