A monorepo for World of Warcraft spell rotation simulation and analysis.

WoW Lab provides a high-performance, event-driven simulation engine for analyzing WoW spell rotations and damage output. The simulation core is written in Rust (crates/engine/) with WASM bindings for browser use. Shared types and parsers live in crates/common/ which compiles to both native and WASM.

Tech Stack:

• Simulation Engine: Rust (with WASM support for browser)
• Shared Library: Rust (crates/common/) - DBC/CSV parsing, types, stat calculations
• Frontend: Next.js 16, Panda CSS, Park UI, Intlayer (i18n)
• Backend: Supabase (PostgreSQL, Auth, Storage)
• Scheduler: Rust (crates/sentinel/) - Discord bot, chunk scheduler, HTTP metrics
• Package Manager: pnpm (workspace monorepo)

• apps/portal - Next.js 16 web application

• crates/centrifugo - Centrifugo WebSocket beacon for realtime updates
• crates/cli - Command-line tools (wowlab-cli)
• crates/common - Shared types, parsers (DBC/CSV), and stat calculations
• crates/engine - Simulation engine with WASM target
• crates/node - Distributed simulation node (shared library)
• crates/node-gui - GUI for simulation nodes (egui)
• crates/node-headless - Headless simulation node for servers
• crates/sentinel - Task scheduler, Discord bot, HTTP metrics
• crates/supabase - Supabase client with PostgREST and Realtime

• packages/wowlab-engine - WASM bindings for crates/engine
• packages/wowlab-parsers - WASM bindings for parsers
• packages/wowlab-common - WASM bindings for crates/common (packed as .tgz)
