websocat VS cdk-eventbridge-socket

one combination I came to really love this year is babashka (https://github.com/babashka/babashka) + websocat (https://github.com/vi/websocat). I wrote about a method of live web programming with this pair at https://github.com/whacked/cow/blob/main/a%20technique%20for...

babashka isn't strictly necessary; you can also pipe plain text, but pushing hiccup expressions to the browser DOM from the REPL with instant feedback has opened a new world of interactive programming for me.

No... the core of it is a django instance in the cloud with a Vue front end (what you're seeing in the screen shot). To push data in, the client connects to a websocket (using https://github.com/vi/websocat) and push key/value pairs in. I'm not in the middle of gameplay at all.

There's really nothing to this. I just have to provide the bus name and an optional pattern. Now using websocat, I get output like this:

Subscriptions is real-time streaming of data from server to client through WebSocket. You will need a constantly active connection to stream such events. You cannot use curl for this and have to use a WebSocket client like websocat if you want to access it via command line. Once executed, a stream of pending transaction IDs will start flowing in.

I didn't want to pass up the advantage to give a quick look to David Boyne's EventBridgeWebSocket construct. With just a few lines of code, I'm able to actively monitor EventBridge traffic while my test runs!
