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.
