Graphite is a free, open-source vector and raster graphics editor with a fully nondestructive editing workflow. It combines layer-based compositing with node-based generative design, enabling procedural content creation. The system is architected as a multi-crate Rust workspace with a desktop application (using Chromium Embedded Framework for UI and wgpu for GPU rendering) and a web frontend (Svelte + Vite compiled to WebAssembly). The core document model is a node graph executed by an interpreted runtime with GPU shader support via rust-gpu. Storage uses a CRDT-based format (`.gdd`) with content-addressed deltas, history, and session state, supporting collaborative editing and undo/redo. The editor features a comprehensive tool system (select, pen, brush, shape, text, etc.), a node graph editor, color management, raw image decoding, and vector path operations. The frontend communicates with the Rust backend through a message-passing architecture with hierarchical message types and a dispatcher pattern. The project also includes a CLI tool for export, a build system (cargo-run), and extensive developer tooling (bisect tool, crate hierarchy visualizer, node documentation generator).
This is a monorepo for a web-based vector graphics editor (similar to Figma) built with React, Canvas2D, and TypeScript. It features a core editor with drawing tools, layers, path editing, undo/redo, SVG import/export, and real-time multiplayer collaboration (via Yjs/Hocuspocus). The architecture includes a standalone editor app, a deprecated multiplayer variant, a backend (NestJS + Prisma + PostgreSQL) for authentication and file storage, and a workbench for team management. Shared packages provide geometry utilities, UI components, icons, and Skia PathKit WASM bindings. The codebase demonstrates strong engineering patterns (command pattern, event emitter, strategy pattern) and provides several reusable components, especially the geometry library and UI components. However, there is significant code duplication between the standalone and multiplayer apps, and the multiplayer app is deprecated, indicating some drift risks. The backend is functional but has minimal stubs and a hardcoded JWT secret.
