• Node.js v22+
• Bun
• Docker (for local database)

# Install dependencies (.env file is created automatically)
bun install

# For static site development
bun --filter pages dev

# For web app development
bun --filter api start     # Start Supabase API
bun --filter api generate  # Generate TypeScript types (only when schema changes)
bun --filter web dev       # Start web development server

Note: TypeScript types are committed to the repository, so you only need to run generate when the database schema changes.

After running bun install, a .env file is automatically created from .env.example. Fill in the required values:

For local development:

• PUBLIC_SUPABASE_URL - http://127.0.0.1:54321
• PUBLIC_SUPABASE_ANON_KEY - Copy the anon key displayed when running bun --filter api start

For production deployment:

• PUBLIC_SUPABASE_URL - https://[project-id].supabase.co
• PUBLIC_SUPABASE_ANON_KEY - Get from Supabase Dashboard > Project Settings > API Keys

Optional (for advanced operations):

• DATABASE_URL - Enables bun --filter api push/pull to target production database
• SUPABASE_SERVICE_ROLE_KEY - Server-side admin access for Edge Functions, Webhooks (never use in browser!)

• Svelte for VS Code
• ESLint
• Prettier
• Tailwind CSS IntelliSense
• EditorConfig

# Development Workflow

# Start development servers
bun --filter api start          # Start Supabase API (port 54321)
bun dev                         # Start all development servers
# Or specific apps:

bun --filter web test           # Test web app
bun --filter pages test         # Test static site

# Code formatting
bun format                      # Format code across all apps

cd apps/api
bun start            # Start Supabase locally
bun stop             # Stop Supabase
bun status           # Show Supabase service status
bun reset            # Reset database and regenerate types
bun generate         # Generate TypeScript types
bun test             # Run Supabase tests

cd apps/web
bun dev              # Start development server (port 5173)
bun build            # Build for production
bun preview          # Preview production build
bun test             # Run Vitest tests
bun lint             # Run linting

cd apps/pages
bun dev              # Start development server (port 3000)
bun build            # Build static site with Tailwind CSS
bun test             # Validate links, images, and accessibility (Note: Delete tests/external-links.txt before bun test to update URL tracking)
bun lint             # Run HTML validation with markuplint
bun run deploy       # Deploy to server (rsync)

# Optimization Utilities
bun add-size-to-img  # Add width/height to <img> tags for better performance
bun clean-image      # Remove unused images from project

TypeScript types are automatically generated from your Supabase database schema:

1. Local Development: Types are generated to apps/api/$generated/types.ts
2. Frontend Usage: Types are imported from the api package (e.g., import type { Database } from 'api/types')
3. After Schema Changes: Run bun generate to update types

Common components and types are available through the @repo/shared package:

// Import UI components
import { Button } from '@repo/shared/components/ui/button';
import * as Card from '@repo/shared/components/ui/card';

// Import shared types
import type { UserProfile } from '@repo/shared/types/user';

// Import constants
import { DEFAULT_EASE } from '@repo/shared/constants/easing';

You can easily switch between development and production environments:

1. For Development: Use local Supabase (started with bun start)
2. For Production Testing: Update .env with production Supabase credentials
3. Type Safety: Types are committed to repository for CI/CD compatibility

The project supports deploying both apps as separate Vercel projects. Each app includes its own vercel.json configuration file.

Configuration:

• Framework Preset: SvelteKit
• Root Directory: apps/web
• Build Command: Automatically configured via apps/web/vercel.json
• Install Command: Automatically configured via apps/web/vercel.json

Environment Variables: Set the following environment variables in your Vercel project settings:

PUBLIC_SUPABASE_URL=https://your-project.supabase.co
PUBLIC_SUPABASE_ANON_KEY=your-anon-key
PUBLIC_GA4_MEASUREMENT_ID=G-XXXXXXXXXX  # Optional

• Framework Preset: Other
• Root Directory: apps/pages
• Build Command: Automatically configured via apps/pages/vercel.json
• Install Command: Automatically configured via apps/pages/vercel.json
• Output Directory: public

• Use bun run deploy command in apps/pages
• Configure server details in deployment script
• Direct file transfer to your server

1. Create two separate Vercel projects from the same GitHub repository
2. Set different Root Directory for each project:
   • Web App: apps/web
   • Static Pages: apps/pages
3. Each project will use its respective vercel.json configuration
4. Configure environment variables for the web app project
