Server-Sent Events
Server-Sent Events (SSE) is a web technology that enables servers to push real-time updates to clients over a single, long-lived HTTP connection. It allows servers to send event streams to web browsers or other clients, facilitating one-way communication from server to client. SSE is commonly used for live notifications, stock tickers, or any scenario where the server needs to push data without client requests.
Developers should learn SSE when building applications requiring real-time server-to-client updates, such as live dashboards, news feeds, or monitoring systems, as it is simpler to implement than WebSockets for one-way data flow. It is particularly useful in scenarios where bidirectional communication isn't needed, reducing complexity and overhead compared to alternatives like WebSockets.
