Your app is async so take advantage of it for development!
summary
An asyncio app runs an in-process HTTP/websocket server that exposes a remote REPL and remote canvas visualizations implemented as Python draw methods borrowed from Processing; those draw calls run only when a client connects (about 10 frames/sec), assemble JS canvas commands and broadcast them to all viewers. The tool Pura is liberally licensed, widely adopted on the project, imposes zero overhead when not observed, and the team reports development and QA literally stop if it is removed.
