Daily Term: Server-Sent Events

Server-Sent Events

Server-Sent Events (SSE) is a standard that allows servers to push real-time updates to clients over HTTP. The server sends a stream of events (e.g., text messages) to the browser, which listens for updates using the EventSource API. SSE is simpler than WebSocket for unidirectional communication, such as live news feeds or stock tickers, but it lacks support for client-to-server messaging and can be less efficient for high-frequency updates.
