tldraw is a monorepo providing an open-source infinite-canvas SDK for building collaborative whiteboard/drawing applications in React. The core library (`@tldraw/editor`, `@tldraw/tldraw`) exposes a highly extensible shape/tool/overlay system with signal-based reactivity, real-time synchronization (`@tldraw/sync-core`), and a full UI component library (menus, toolbars, dialogs, style panels, commenting). The repository also includes a production-grade web application (tldraw.com) with authentication (Clerk), file management, real-time sync via Cloudflare Durable Objects, MCP server integration, and a Zero-based relational data layer for multi-user features. Additional assets include a VS Code extension, an AI agent starter kit, a documentation site, an extensive example gallery (~100+ recipes), and deployment infrastructure for Cloudflare Workers, Vercel, and template demos. The architecture is modular—core packages have minimal dependencies—and the codebase demonstrates strong engineering practices: comprehensive unit and e2e testing, a custom validation library with path-aware errors, an efficient small-set implementation (`ArraySet`), and a debounce utility that returns cancelable promises.
skpm is a Sketch Plugin Manager providing a CLI utility to create, build, test, and publish Sketch plugins. It's structured as a monorepo with specialized packages: skpm (main CLI), builder (build/linking), create-sketch-plugin (plugin scaffolding), test-runner (testing framework), and shared utilities. The system handles the full plugin lifecycle from creation to publishing, including webpack/Babel compilation, asset bundling, GitHub integration for releases, and Sketch-specific features like developer mode toggling and log viewing.
This repository contains design assets for the United States Web Design System (USWDS) in various formats (Figma, Sketch, Adobe XD) along with icon sets and fonts. It serves as a resource for designers to access and customize USWDS components, colors, and typography. The repository is primarily a collection of design files rather than executable code, with minimal technical implementation. The Figma file is noted as the most up-to-date format, while Sketch and Adobe XD assets are less actively maintained. The repository includes contribution guidelines and licensing information, but the core value lies in the design assets themselves.
