Example for handling long lived SSE connections

[IcelandicIcecream]

Hey! Great work on the framework, gonna use it for most of my projects from now on. Just wanted to ask if there is an example for a long lived SSE connection. Like how do I handle user disconnects and etc. Also, how do I handle errors for SSE connections? Im using the example with send.Data as reference

Hi! You can check that you client is alive by send.Data(), this func return error if connection lost or connection has any other error. For example you can send ping event every 10s. Yep, this is not perfect solution, but it can works correctly.

Alright. thanks for the suggestion! Will do this in the meantime. If I remember correctly, maybe we can actually run a separate goroutine to check for ctx.Done(). Will do some testing and let you know!

@IcelandicIcecream FYI there is a more complete FizzBuzz SSE example here:

https://github.com/danielgtaylor/huma/blob/main/examples/sse/main.go

It includes ending the handler when send.Data(...) fails:
