7- 🍎 Web interface for entering food descriptions
8- 🤖 AI-powered calorie estimation using OpenAI GPT-4o
9- 📊 Automatic logging to Notion database
10- 🎨 Clean, responsive UI with TailwindCSS
17
18- `NOTION_OAUTH_TOKEN` - Your Notion OAuth token
19- `OPENAI_API_KEY` - Your OpenAI API key (handled by Val Town's OpenAI integration)
20
21### Notion Database
39- `main.http.ts` - HTTP trigger with web interface and AI integration
40- `notion.ts` - Notion API integration for logging food entries
41- Uses Val Town's OpenAI integration for GPT-4o access
42- Responsive web UI built with TailwindCSS
43
46This version has been migrated from a Bun CLI script to a Val Town HTTP trigger:
47
48- ✅ Uses Val Town's OpenAI integration instead of direct OpenAI SDK
49- ✅ Environment variables use `Deno.env.get()` instead of `process.env`
50- ✅ ESM imports from `https://esm.sh` for compatibility
94Note: When changing a SQLite table's schema, change the table's name (e.g., add _2 or _3) to create a fresh table.
