Real-time data streaming is critical for modern applications—whether it’s live notifications, financial dashboards, multiplayer gaming, or collaborative tools. But traditional solutions like WebSockets and polling often introduce scalability issues, high resource consumption, and unnecessary complexity.

In this session, we’ll explore Server-Sent Events (SSE) as a scalable, lightweight alternative for real-time communication. Using Next.js & NestJS, we’ll compare SSE vs WebSockets vs Polling, analyze performance trade-offs, and implement an optimized real-time data streaming system.
What You’ll Learn:

- Why SSE? When to use it instead of WebSockets or Polling.
- Hands-on Demo: Implementing a real-time data feed using SSE.
- Performance & Scalability: How SSE reduces overhead in high-frequency data updates.
