Doodleopia

Yet another collaborative drawing app, born from the 2020 Pandemic.

Features/Shortcomings

• SVG with no canvas intermediate.
• Shared cursors for collaborative feedback.
• Zoomable and pannable.
• Continuous 'Recording' of drawings with playback.
• 'Turtle' and a 2d L-systems interpreter (hidden feature).

Implementation Details

• Go backend using Gorilla for websockets.
• Vanilla Typescript frontend, no framework.
• Uses FlatBuffers for messaging.
• Uses Snowpack for frontend dev. (cool)
