A SvelteKit app that tracks ski resort conditions and creates personalized alerts using AI. This is the starter project for the Svelte on Vercel course.

npm install
cp .env.example .env  # Add your AI_GATEWAY_API_KEY
npm run dev

Open http://localhost:5173 to see the app.

The UI, data layer, and routing are ready to go:

• Conditions dashboard showing live weather for 5 ski resorts
• Alerts page with localStorage persistence
• Chat interface wired up and waiting for a streaming endpoint
• Resort data for Mammoth, Palisades Tahoe, Grand Targhee, Steamboat, and Mt. Bachelor
• Weather service pulling from Open-Meteo (free, no API key needed)
• Alert schemas validated with Valibot

Look for // TODO: comments in the codebase. Throughout the course, you'll implement:

1. AI chat endpoint (src/routes/api/chat/+server.ts): Streaming responses with tool calling
2. Structured output (src/routes/api/parse-alert/+server.ts): Natural language to structured alert data
3. Background workflow (src/routes/api/workflow/+server.ts): Durable execution with error handling
4. ISR caching (src/routes/+page.server.ts): Incremental Static Regeneration for the dashboard
5. AI provider (src/lib/ai/provider.ts): Centralized model config with usage tracking
