+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+Luncher is a lunch management app for teams — daily restaurant menus, food ordering, pizza day events, and payment QR codes. Czech-language UI. Full-stack TypeScript monorepo.
+
+## Monorepo Structure
+
+```
+types/    → Shared OpenAPI-generated TypeScript types (source of truth: types/api.yml)
+server/   → Express 5 backend (Node.js 22, ts-node)
+client/   → React 19 frontend (Vite 7, React Bootstrap)
+```
+
+Each directory has its own `package.json` and `tsconfig.json`. Package manager: **Yarn Classic**.
+
+## Development Commands
+
+### Initial setup
+```bash
+cd types && yarn install && yarn openapi-ts   # Generate API types first
+cd ../server && yarn install
+cd ../client && yarn install
+```
+
+### Running dev environment
+```bash
+# All-in-one (tmux):
+./run_dev.sh
+
+# Or manually in separate terminals:
+cd server && NODE_ENV=development yarn startReload   # Port 3001, nodemon watch
+cd client && yarn start                               # Port 3000, proxies /api → 3001
+```
+
+### Building
+```bash
+cd types && yarn openapi-ts      # Regenerate types from api.yml
+cd server && yarn build          # tsc → server/dist
+cd client && yarn build          # tsc --noEmit + vite build → client/dist
+```
+
+### Tests
+```bash
+cd server && yarn test           # Jest (tests in server/src/tests/)
+```
+
+### Formatting
+```bash
+# Prettier available in client (no config file — uses defaults)
+```
+
+## Architecture
+
+### API Types (types/)
+- OpenAPI 3.0 spec in `types/api.yml` — all API endpoints and DTOs defined here
+- `yarn openapi-ts` generates `types/gen/` (client.gen.ts, sdk.gen.ts, types.gen.ts)
+- Both server and client import from these generated types
+- **When changing API contracts: update api.yml first, then regenerate**
+
+### Server (server/src/)
+- **Entry:** `index.ts` — Express app + Socket.io setup
+- **Routes:** `routes/` — modular Express route handlers (food, pizzaDay, voting, notifications, qr, stats, easterEgg, dev)
+- **Services:** domain logic files at root level (`service.ts`, `pizza.ts`, `restaurants.ts`, `chefie.ts`, `voting.ts`, `stats.ts`, `qr.ts`, `notifikace.ts`)
+- **Auth:** `auth.ts` — JWT + optional trusted-header authentication
+- **Storage:** `storage/StorageInterface.ts` defines the interface; implementations in `storage/json.ts` (file-based, dev) and `storage/redis.ts` (production). Data keyed by date (YYYY-MM-DD).
+- **Restaurant scrapers:** Cheerio-based HTML parsing for daily menus from multiple restaurants
+- **WebSocket:** `websocket.ts` — Socket.io for real-time client updates
+- **Mock mode:** `MOCK_DATA=true` env var returns fake menus (useful for weekend/holiday dev)
+- **Config:** `.env.development` / `.env.production` (see `.env.template` for all options)
+
+### Client (client/src/)
+- **Entry:** `index.tsx` → `App.tsx` → `AppRoutes.tsx`
+- **Pages:** `pages/` (StatsPage)
+- **Components:** `components/` (Header, Footer, Loader, modals/, PizzaOrderList, PizzaOrderRow)
+- **Context providers:** `context/` — AuthContext, SettingsContext, SocketContext, EasterEggContext
+- **Styling:** Bootstrap 5 + React Bootstrap + custom SCSS files (co-located with components)
+- **API calls:** use OpenAPI-generated SDK from `types/gen/`
+- **Routing:** React Router DOM v7
+
+### Data Flow
+1. Client calls API via generated SDK → Express routes
+2. Server scrapes restaurant websites or returns cached data
+3. Storage: Redis (production) or JSON file (development)
+4. Socket.io broadcasts changes to all connected clients
+
+## Environment
+
+- **Server env files:** `server/.env.development`, `server/.env.production` (see `server/.env.template`)
+- Key vars: `JWT_SECRET`, `STORAGE` (json/redis), `MOCK_DATA`, `REDIS_HOST`, `REDIS_PORT`
+- **Docker:** multi-stage Dockerfile, `compose.yml` for app + Redis. Timezone: Europe/Prague.
+
+## Conventions
+
+- Czech naming for domain variables and UI strings; English for infrastructure code
+- TypeScript strict mode in both client and server
+- Server module resolution: Node16; Client: ESNext/bundler
+
+## Code Search Strategy
+When searching through the project for information, use the Task tool to spawn
+subagents. Each subagent should read the relevant files and return a brief
+summary of what it found (not the full file contents). This keeps the main
+context window small and saves tokens. Only pull in full file contents once
+you've identified the specific files that matter.
+When using subagents to search, each subagent should return:
+- File path
+- Whether it's relevant (yes/no)
+- 1-3 sentence summary of what's in the file
+Do NOT return full file contents in subagent responses.

 - Zkopírovat `server/.env.template` do `server/.env.development` a upravit dle potřeby
-- Spustit `./run_dev.sh`. Na jiných platformách se lze inspirovat jeho obsahem, postup by měl být víceméně stejný.
