Server-Sent Events (SSE) Revisited
Re-evaluate SSE for unidirectional server-to-client streaming and compare it with WebSockets for specific use cases.
Revisiting Server-Sent Events
Welcome back to Server-Sent Events (SSE)! While we briefly touched upon SSE earlier, this lesson dives deeper into its unique strengths and optimal use cases in modern realtime web development.
In a world dominated by WebSockets for full-duplex communication, SSE holds its ground for specific scenarios where a simpler, unidirectional stream is all you need.
SSE: Server-to-Client Only
The fundamental principle of SSE is its unidirectional nature. It allows a server to push updates to a client over a single, persistent HTTP connection.
- Data flows only from the server to the client.
- Clients cannot send messages back to the server using the same SSE connection.
- This simplicity makes it ideal for broadcast-style updates.
