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/:

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/:

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:

{#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/
