Tasos Bitsios - The Power of SSE: unidirectional streaming protocol you aren't using - React Live

Discover the power of SSE, a simple and unidirectional streaming protocol for real-time updates, including reconnection and error handling strategies, event sourcing, and more.

Key takeaways

SSE (Server-Sent Events) is a simple, unidirectional streaming protocol.
It’s not widely used and has some issues, such as reconnection and error handling.
SSE can be used for real-time updates, like notifications, and is suitable for small-scale use cases.
The eventsource library is recommended for easy use.
Trents are recommended for handling reconnecting.
The readyState property is important for handling connection management.
SSE can be used in a shared worker for event sourcing.
Event sources can be named for better handling.
Simple, named events and custom data events can be used.
The retry field in the event data can be used to set a desired reconnecting time.
Error handling is important, with solutions like giving up and not retrying.
The heartbeat event can be used for detecting stale connections.
Event sourcing can be used for stream processing.
The status event can be used for connection management.
SSE is compatible with HTTP/2 and WebSockets.
The curl command can be used to debug SSE connections.
SSE can be used for simple, real-time updates, like those needed for commentary on a sports event.
The eventsource library can be used to handle event sourcing with SSE.
Trents can be used to implement reconnection strategies.
The readyState property is important for handling connection management.
SSE can be used with a shared worker and separate endpoints for each event type.
Error handling is important and can involve giving up and not retrying.
