reanimate/playground

Always run with GHCi. Forbid TemplateHaskell. Generate a single frame at a time. Stop generating frames once a limit is hit:

• 5 seconds iff there's a queue.
• 30 seconds if there isn't a queue.
• 5 megs of disk space used.
• Framerate hits 30 fps.
• Code crashes.
• Code hits memory ceiling.
• New render request from the same user. Queue rendering. Skip queue when cache hit.

Test against:

• last [1..]
• let e = error ("error: " ++ e) in e

How to run locally:

Backend

stack build
stack exec --cwd ../ playground

Frontend

By default the frontend will use the backend running at reanimate.clozecards.com. To switch to a local backend, change 'backend' in Main.elm to 'Local'.

cd viewer-elm
npm install
npm run dev-server

Design

The playground frontend connects to the backend (reanimate.clozecards.com) over HTTPS. The backend runs nginx to serve static files and as a reverse proxy for the websocket server. All backend services are run in docker and auto-updated. SSL certificate is from lets-encrypt.org Frontend is written in Elm and automatically deployed to reanimate's GitHub Page on every push to master. The built-in examples are in the 'snippets/' folder and they are type-checked on every commit to master.
