โ„น๏ธ About SSE

Server-Sent Events (SSE) provide a simple way to push real-time updates from server to client over HTTP. Unlike WebSockets, SSE is one-directional (server โ†’ client), uses standard HTTP, supports automatic reconnection, and works through proxies. The browser's EventSource API handles connection management. Common use cases include live feeds, AI streaming responses, notifications, and log tailing.
