Multiplayer Terminal Canvas

A collaborative, real-time ASCII terminal canvas web application. Draw with friends using strictly constrained cellular grids, supporting infinite panning, zooming, light/dark modes, and SVG exports.

Features

• Real-time Collaboration: Powered by WebSockets and a custom binary protocol for high performance.
• Terminal Grid: Characters snap perfectly to a monospace cellular grid.
• Modern UI: Floating toolbars, interactive user status, and smooth View Transition API theme toggling.
• Pan & Zoom: Infinite panning (Right-click/Two-finger) and smooth zooming (Scroll-wheel/Slider/+/-).
• Export: Export the entire canvas as a perfectly mapped, portable SVG.

Tech Stack

• Backend: Bun + TypeScript (Native WebSockets server)
• Frontend: Vanilla HTML, CSS, JavaScript (Zero frameworks, hardware-accelerated transforms)
