EventSource
EventSource is a web technology that allows a web page to receive real-time updates from a server. It establishes a persistent connection, so the server can send data automatically whenever there's new information, without the user needing to refresh the page. This is useful for live updates like chat messages, notifications, or stock prices. Unlike traditional methods that repeatedly ask the server for updates, EventSource keeps a continuous connection open, making data delivery more efficient and timely. It's a standard feature supported in modern browsers, simplifying real-time communication between servers and web pages.
