Hi everyone. I am exploring SSE functionality in Ktor 3. Can somebody please help me understand the purpose of the while (true) loop in this example? I tried running that code and it seems to work fine with or without the while (true) loop in place.

My guess is that the loop facilitate’s the browser’s automatic reconnection when using EventSource

Thank you, Casey.

I am little confused about the ability to reconnect an SSE connection in Ktor 3. Ktor documentation here describes the reconnectionTime property, suggesting that it is supported. However, a note immediately after that says "Note that reconnection is currently not supported."

Can somebody who is knows please clarify the situation?

The automatic reconnection isn't supported yet. Please follow https://youtrack.jetbrains.com/issue/KTOR-6242 for updates. The documentation will be updated.

Thank you, @Aleksei Tirman [JB].

Can you please also help me understand the purpose of while(true) loop in the example code in Ktor documentation?

[Aleksei Tirman [JB]]

It's redundant because the collect method collects all events anyway.

Thank you!

@Aleksei Tirman [JB] do you know if Automatic reconnection is something that will be added soon? There are no updates on the ticket other than linking to it from other tickets.

[Aleksei Tirman [JB]]

The work should be started soon on that issue.
