Multi User Canvas
Multi-User Canvas is a simple app that lets you draw on a canvas with other users, in real-time. May possibly expand in scope...
Example Run Configurations
The current version has no extra dependencies so can be run straight up with docker like this:
docker run -it --rm -p 3000:3000 leoadamek/muc
The container exposes port 3000 for the application, note that WebSockets are required for performance, so ensure that any proxy (e.g. nginx) is set up to handle them.
