# CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

## Project Overview

stammtisch-hersbruck.de is a SvelteKit 5 application using Svelte 5's new runes syntax ($state, $props, etc.) with PocketBase as the backend. The app manages events, runs, riders, times and teams for a motorsport/cycling event organization.

The repository is a monorepo: the SvelteKit app lives in `frontend/`, the PocketBase instance in `backend/`.

## Development Commands

Alle Frontend-Befehle laufen aus `frontend/`:

```bash
cd frontend

# Start development server (runs on http://stammtisch-hersbruck.de.localhost:31337)
npm run dev

# Build for production
npm run build

# Preview production build
npm run preview

# Type-check Svelte files
npm run check

# Type-check with watch mode
npm run check:watch

# Generate TypeScript types from the schema migration in backend/pb_migrations
# (no running instance, no token, no network access needed)
npm run generate-pocketbase-types
```

Backend (PocketBase) aus `backend/`:

```bash
cd backend

# PocketBase lokal starten (Admin-UI auf http://127.0.0.1:8090/_/)
docker compose up -d --build

# Stoppen
docker compose down
```

## Architecture

### Backend Integration (PocketBase)

- **API Base URL**: konfigurierbar über `PUBLIC_PB_URL` in `frontend/.env`.
  Default ist die produktive Instanz `https://api.stammtisch-hersbruck.de`;
  für das lokale Backend aus `backend/` auf `http://127.0.0.1:8090` umstellen.
- **Schema**: versioniert als Migration in `backend/pb_migrations/`, kommt per
  `COPY` ins Image (kein Bind-Mount — der würde das Image-Verzeichnis
  überdecken). Im Admin-UI erzeugte Migrationen liegen deshalb zunächst nur im
  Container und müssen mit `docker compose cp` ins Repo geholt werden; siehe
  `backend/README.md`.
- **Type-safe client**: The PocketBase client is typed using auto-generated types in `frontend/src/lib/types.d.ts`
- **Collections**: users, teams, events, runs, riders, times
- **Authentication**: Handled through `src/lib/stores/pocketbase.svelte.ts` with the `AuthStore` class
- **File handling**: Use `getFileURL(record, file, options)` helper for PocketBase file URLs

### State Management Pattern

The app uses Svelte 5 runes for state management with a custom store pattern:

1. **Global stores** in `src/lib/stores/`:
   - `pocketbase.svelte.ts`: PocketBase client, auth, and collection operations
   - `app.svelte.ts`: Global app state (theme, navigation, confirm dialogs, hotkeys)
   - `teams.svelte.ts`: Example of collection-specific store pattern

2. **Collection store pattern**:
   - Each collection has a context-based store (see `teams.svelte.ts` as template)
   - Use `setTeamContext()` in parent and `getTeamContext()` in children
   - Stores provide: `records`, `refresh()`, `create()`, `edit()`, `remove()`
   - The `collections` helper in `pocketbase.svelte.ts` provides reusable CRUD operations

3. **Auth flow**:
   - Auth state lives in `auth` store from `pocketbase.svelte.ts`
   - Cookie-based persistence available via `auth.cookie` flag
   - Auth store syncs with PocketBase `authStore.onChange()`

### UI Components

- **UI Library**: Using shadcn-svelte components (bits-ui based)
- **Component path alias**: `@/components/ui/*` maps to `$lib/components/ui/*`
- **Styling**: Tailwind CSS 4.x with custom configuration
- **Dark mode**: Handled by `mode-watcher` package, toggle with `toggleMode()`
- **Tooltips**: Global `tooltip` action available from `app.svelte.ts` using tippy.js

### Important Patterns

**Svelte 5 Runes**: This project uses Svelte 5 syntax exclusively:
- `$state()` for reactive state (not `let` with `$:`)
- `$props()` for component props
- `$derived()` for computed values
- `{@render children?.()}` for slot content

**Type Generation**: After modifying the schema migration in `backend/pb_migrations/`, run `npm run generate-pocketbase-types` to update `frontend/src/lib/types.d.ts`. The script reads the collections array straight out of the migration (`frontend/scripts/schema-to-json.mjs`) — schema and types come from the same versioned source and cannot drift apart. Commit the regenerated file.

**Async Data Loading**: Root layout (`src/routes/+layout.svelte`) shows pattern:
```svelte
{#await load()}
  <!-- loading state -->
{:then _}
  <!-- main content -->
{/await}
```

**Confirm Dialogs**: Use `app.confirm.request()` for user confirmations (see `events.svelte.ts` remove pattern).

**Hotkeys**: Use `app.hotkey(event, condition, callback)` which auto-ignores input fields and contenteditable elements.

### Project Configuration

- **Repo-Struktur**: Monorepo mit `frontend/` (SvelteKit) und `backend/`
  (PocketBase). Ein einziges Git-Repo im Root.
- **Dev server port**: 31337 (strict mode, custom domain: `stammtisch-hersbruck.de.localhost`)
- **Path alias**: `@/*` resolves to `./src/lib/*` (configured in frontend/svelte.config.js)
- **Adapter**: `@sveltejs/adapter-node` — Deployment läuft über Coolify mit
  `node build`. `adapter-auto` erkennt Coolify nicht und erzeugt kein `build/`.
- **Node**: `engines` verlangt `^20.19 || ^22.12 || >=24`; mit
  `engine-strict=true` (`.npmrc`) bricht `npm ci` sonst mit `EBADENGINE` ab.
- **Deployment-Env**: `PUBLIC_PB_URL` muss dort gesetzt sein — sie wird zur
  Buildzeit eingesetzt, und die lokale `.env` ist gitignored.

### File Structure Notes

- Routes are in `src/routes/` following SvelteKit conventions
- Reusable components in `src/lib/components/`
- Stores use `.svelte.ts` extension for Svelte 5 runes
- Static assets in `static/`
- `components.json` configures shadcn-svelte CLI

## When Working with This Codebase

- Always use Svelte 5 runes syntax, never legacy Svelte syntax
- Use the official Svelte MCP server to validate Svelte code
- Collection stores should follow the pattern in `teams.svelte.ts`
- PocketBase operations go through the `collections` helper for consistency
- UI components should use the shadcn-svelte imports from `@/components/ui/`
