Ruby HTTP Streaming Revisited

This morning I read "You might not need Websockets". It reminded me of the rack-stream gem 13 years ago to explore the HTTP Streaming API.

Here's a list of changes since then I've noticed:

• Rail's ActionCable abstracts websocket connection management
• Turbo streaming can work through websockets or eventsource
• ActionController::Streaming can stream layouts earlier with some caveats around middlewares and layouts
• falcon is a newer async ruby web server
