Server-Sent Events (SSE) vs. WebSockets
Compare SSE and WebSockets, understanding when to choose each technology for specific real-time needs.
Real-Time: Beyond Request-Response
Modern web applications often need instant updates. Think live scores, chat messages, or stock price changes. Traditional HTTP's request-response model isn't always ideal for these scenarios.
We need ways for the server to push data to the client without the client constantly asking for it.
WebSockets: A Quick Refresher
You've learned about WebSockets. They establish a persistent, full-duplex connection between a client and server over a single TCP connection.
- Full-duplex: Both client and server can send and receive messages independently at any time.
- Great for highly interactive applications like chat or multiplayer games.
