A simple multi-user drawing canvas built with Elixir & Phoenix.
Uses WebSockets through Phoenix Channels to synchronize drawing in soft real-time amongst users, and stores drawings in ETS to serve existing drawings to new users when they open the canvas in their browser.
Deployment is done with Heroku (see Procfile and app.json for configuration). Currently you'll also need to configure the URL in config/prod.exs.
- Install dependencies with
mix deps.get - Install Node.js dependencies with
cd assets && npm install - Start Phoenix endpoint with
mix phx.server
Now you can visit localhost:4000 from your browser.
