This is a large, production-grade collaborative crafting companion for Final Fantasy XIV, consisting of an Angular web application (with SSR) and an Electron desktop client, plus a NestJS API and Firebase backend. The primary functionality includes crafting list management with tree-based ingredient breakdown, a full crafting rotation simulator, gearset planning with stat calculations and materia optimization, real-time gathering alarms based on Eorzea time and weather, marketboard price tracking via Universalis, inventory capture and optimization, fishing data and cooperative fishing train tool, commission board for player-to-player crafting services, free company workshop and airship/submarine management, island sanctuary workshop optimization, and a crowd-sourced data reporting system (Allagan Reports) for fish/hookset/bite times and desynthesis results. The codebase demonstrates advanced Angular/NgRx patterns, extensive use of RxJS for reactive data flows, a sophisticated lazy data loading system for game data extracted from the FFXIV client, and tight desktop integration via Electron IPC and packet capture. While there are some legacy patterns and a large feature surface that introduces maintenance complexity, the architecture is well-separated into libraries, the core data abstraction (LazyDataFacade, FirestoreRelationalStorage, base dialog components) is highly reusable, and the project remains actively developed with a large user and contributor community.
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.
