HTTP response streaming in app platform (for SSE support)

Roger P

I'm trying to serve Server-Sent Events (SSE) using Flask on the DO App Platform, but instead of streaming, something on DO's side seems to be caching the entire response and only returning it in one big chunk. I've been trying and trying to debug, and finally found this page which seems to indicate it's not possible? https://www.digitalocean.com/community/questions/how-to-enable-http-response-streaming-in-the-app-platform

So I have to migrate off the app platform now I guess? Or am I missing something?

Next.js apps don't work properly without this feature enabled. +1

I am having the same problem and it would be great if the App Platform properly supported SSE. Our SSE server works fine when I run it locally and on other platforms, but when it is run on your App Platform, the event responses are not sent each time they are written, but only as a huge chunk when the server ends the response stream. The server is also not detecting when the client ends the connection.
