Server-Sent Events (SSE) for Unidirectional Push

Welcome! In this lesson, we'll explore Server-Sent Events (SSE), a powerful yet simple way for servers to push real-time updates to clients.

Unlike traditional HTTP requests where the client always asks the server for data, SSE allows the server to send data to the client whenever new information is available, without the client needing to constantly poll.

You might be familiar with WebSockets for real-time communication. While WebSockets enable full two-way communication, SSE is designed specifically for unidirectional data flow, from the server to the client.

This makes SSE a simpler and often more efficient choice for scenarios where the client only needs to receive updates, not send them back in real-time.
