App This document describes the Sanity schema required for the restaurant menu app. ## Environment Variables Add these to your project: ``` NEXT_PUBLIC_SANITY_PROJECT_ID=your-project-id NEXT_PUBLIC_SANITY_DATASET=production ``` ## Sanity Schemas ### 1. Allergen Document ```javascript export default { name: 'allergen', title: 'Allergen', type: 'document', fields: [ { name: 'name', title: 'Name', type: 'string', validation: Rule => Rule.required() }, { name: 'icon', title: 'Icon', type: 'string', description: 'Emoji or icon representation' } ] } ``` ### 2. Ingredient Document ```javascript export default { name: 'ingredient', title: 'Ingredient', type: 'document', fields: [ { name: 'name', title: 'Name', type: 'string', validation: Rule => Rule.required() }, { name: 'isVeg', title: 'Is Vegetarian', type: 'boolean', initialValue: true }, { name: 'jainCompatible', title: 'Jain Compatible', type: 'boolean', initialValue: true }, { name: 'allergen', title: 'Associated Allergen', type: 'reference', to: [{type: 'allergen'}] } ] } ``` ### 3. MenuItem Document (CORE SCHEMA) ```javascript export default { name: 'menuItem', title: 'Menu Item', type: 'document', fields: [ { name: 'name', title: 'Dish Name', type: 'string', validation: Rule => Rule.required() }, { name: 'description', title: 'Description', type: 'text', rows: 3 }, { name: 'category', title: 'Category', type: 'string', options: { list: [ {title: 'Starter', value: 'starter'}, {title: 'Main Course', value: 'main'}, {title: 'Dessert', value: 'dessert'}, {title: 'Beverage', value: 'beverage'} ] }, validation: Rule => Rule.required() }, { name: 'price', title: 'Price', type: 'number', validation: Rule => Rule.required().min(0) }, { name: 'image', title: 'Image', type: 'image', options: { hotspot: true } }, { name: 'isVeg', title: 'Is Vegetarian', type: 'boolean', initialValue: true }, { name: 'isVegan', title: 'Is Vegan', type: 'boolean', initialValue: false }, { name: 'isJain', title: 'Is Jain', type: 'boolean', initialValue: false, description: 'No onion, no garlic' }, { name: 'containsOnion', title: 'Contains Onion', type: 'boolean', initialValue: false }, { name: 'containsGarlic', title: 'Contains Garlic', type: 'boolean', initialValue: false }, { name: 'containsEgg', title: 'Contains Egg', type: 'boolean', initialValue: false }, { name: 'meatType', title: 'Meat Type', type: 'string', options: { list: [ {title: 'None', value: 'none'}, {title: 'Chicken', value: 'chicken'}, {title: 'Fish', value: 'fish'}, {title: 'Mutton', value: 'mutton'} ] }, initialValue: 'none' }, { name: 'allergens', title: 'Allergens', type: 'array', of: [{type: 'reference', to: [{type: 'allergen'}]}] }, { name: 'ingredients', title: 'Ingredients', type: 'array', of: [{type: 'reference', to: [{type: 'ingredient'}]}] }, { name: 'spiceLevel', title: 'Spice Level', type: 'number', validation: Rule => Rule.required().min(1).max(5), description: '1 = Mild, 5 = Very Spicy' }, { name: 'availableNow', title: 'Available Now', type: 'boolean', initialValue: true }, { name: 'popularityScore', title: 'Popularity Score', type: 'number', validation: Rule => Rule.min(0).max(100), initialValue: 50, description: 'Used for AI suggestions (0-100)' } ] } ``` ## Sample Data ### Allergens - Peanut (🥜) - Gluten (🌾) - Dairy (🥛) - Tree Nuts (🌰) ### Sample Menu Items 1. **Paneer Tikka** (Veg, not Jain, has onion/garlic, dairy allergen) 2. **Dal Tadka** (Veg, Vegan, not Jain, has onion/garlic) 3. **Jain Veg Pulao** (Veg, Vegan, Jain, no onion/garlic) 4. **Butter Chicken** (Non-veg, chicken, dairy allergen) 5. **Fish Curry** (Non-veg, fish, spicy) 6. **Gulab Jamun** (Veg, Jain, dairy + gluten allergen) ## Filtering Logic The app uses structured fields to filter dishes: 1. **Diet Type Filtering**: Uses `isVeg`, `isVegan`, `isJain` boolean fields 2. **Meat Preferences**: Uses `meatType` enum field 3. **Allergen Filtering**: Uses `allergens` reference array 4. **Spice Filtering**: Uses `spiceLevel` number field 5. **Onion/Garlic**: Uses `containsOnion`, `containsGarlic` boolean fields **IMPORTANT**: Filtering happens via structured data queries, NOT text search. This ensures accurate dietary restriction matching. ## Mock Data The app includes mock data in `/lib/queries.ts` for development. This allows the app to work without a Sanity connection. Replace with real Sanity queries when ready. ## Next Steps 1. Create a Sanity project at sanity.io 2. Install Sanity CLI: `npm install -g @sanity/cli` 3. Set up schemas using the code above 4. Add sample data through Sanity Studio 5. Update environment variables in your Vercel project 6. Deploy! [V0_FILE]markdown:file="README.md" isMerged="true" # What Can I Eat? - Smart Restaurant Menu App A mobile-first web app that helps restaurant customers find dishes they can safely eat based on their dietary preferences, restrictions, and allergens. ## Features ✅ **Preference Selection** - Choose from Vegetarian, Non-Vegetarian, Vegan, or "I eat everything" ✅ **Detailed Filtering** - Jain options, meat preferences, allergen tracking, spice levels ✅ **Smart Menu Display** - Only shows dishes that match your exact preferences ✅ **AI Suggestions** - Get personalized recommendations from safe dishes ✅ **Dish Details** - Full ingredient lists, allergen warnings, and compatibility explanations ✅ **Sanity CMS Backend** - Structured content management for menu items ## Tech Stack - **Next.js 16** with App Router - **React 19.2** with Server Components - **Tailwind CSS v4** for styling - **Sanity CMS** for content management - **TypeScript** for type safety - **shadcn/ui** components ## Pages 1. **/** - Preference selection (What do you eat?) 2. **/preferences** - Detailed dietary preferences 3. **/menu** - Filtered menu with AI suggestions 4. **/dish/[id]** - Individual dish details ## Getting Started ### 1. Install Dependencies ```bash npm install ``` ### 2. Set Up Sanity (Optional) The app works with mock data out of the box. To connect to Sanity CMS: 1. Create a Sanity project at [sanity.io](https://sanity.io) 2. Set up the schemas (see `SANITY_SETUP.md`) 3. Add environment variables: ```env NEXT_PUBLIC_SANITY_PROJECT_ID=your-project-id NEXT_PUBLIC_SANITY_DATASET=production ``` ### 3. Run Development Server ```bash npm run dev ``` Open [http://localhost:3000](http://localhost:3000) to see the app. ## How It Works ### Filtering Logic The app uses **structured fields** from Sanity to filter dishes, NOT text search: - **Diet Type**: `isVeg`, `isVegan`, `isJain` boolean fields - **Meat Preferences**: `meatType` enum (chicken/fish/mutton/none) - **Allergens**: Reference array to allergen documents - **Spice Level**: Numeric scale (1-5) - **Onion/Garlic**: `containsOnion`, `containsGarlic` booleans This ensures **100% accurate** dietary restriction matching. ### AI Suggestions AI suggestions are generated by: 1. Filtering dishes based on preferences (safety first) 2. Ranking by popularity score 3. Explaining why each dish fits the user's needs **Note**: AI only suggests from already-safe dishes. It never recommends unsafe food. ## File Structure ``` /app /page.tsx # Preference selection /preferences/page.tsx # Detailed preferences /menu/page.tsx # Filtered menu /dish/[id]/page.tsx # Dish details /layout.tsx # Root layout /globals.css # Global styles /lib /sanity.ts # Sanity client + types /queries.ts # Menu filtering logic /utils.ts # Utilities (cn) /components/ui/* # shadcn/ui components ``` ## Mock Data The app includes mock menu items in `/lib/queries.ts`: - Paneer Tikka (Veg, dairy) - Dal Tadka (Veg, vegan) - Jain Veg Pulao (Jain-friendly) - Butter Chicken (Non-veg, chicken) - Fish Curry (Non-veg, fish, spicy) - Gulab Jamun (Veg dessert, dairy + gluten) ## Customization ### Colors Edit `/app/globals.css` to change the color scheme: - `--primary`: Main brand color (currently green for trust/food safety) - `--accent`: Secondary accent color (warm orange) - `--background`, `--foreground`: Base colors ### Adding Features - **Payment**: This is NOT an ordering app, but you can add Stripe integration - **Multi-restaurant**: Currently single-restaurant; extend with restaurant schema - **User accounts**: Add auth with Supabase or Auth.js - **QR codes**: Generate QR codes linking to your deployed URL ## Deployment ### Deploy to Vercel ```bash vercel ``` Or connect your GitHub repo to Vercel for automatic deployments. ### Environment Variables Add Sanity credentials in Vercel project settings: - `NEXT_PUBLIC_SANITY_PROJECT_ID` - `NEXT_PUBLIC_SANITY_DATASET` ## Design Principles - **Mobile-first**: Optimized for phone screens - **Large tap targets**: Easy to use while seated at table - **Clear icons**: Visual dietary indicators - **Trustworthy**: Clean design for safety-critical app - **Fast**: Server components + minimal client JS ## License Built with v0 by Vercel.

Details - **Project ID**: `nc06prfm` - **Project Name**: Restaurant Menu - What Can I Eat - **Dataset**: `production` - **Sanity Studio URL**: https://nc06prfm.sanity.studio/ ## What's Been Set Up ### 1. Sanity Project Created A new Sanity project has been created with: - Production dataset - CORS configured for Vercel deployments - API tokens generated (read and write access) ### 2. Schema Defined Local schema files created in `/sanity/schemaTypes/`: - `menuItem.ts` - Complete menu item schema with all dietary fields - Validation rules for required fields - Proper field types and constraints ### 3. Sample Data Loaded 8 menu items have been created and published: - **Paneer Tikka** (Veg, Jain-friendly starter) - **Dal Makhani** (Veg main with onion/garlic) - **Butter Chicken** (Non-veg chicken main) - **Vegetable Biryani** (Vegan main) - **Grilled Fish** (Non-veg fish main) - **Gulab Jamun** (Veg Jain-friendly dessert) - **Masala Chai** (Veg Jain-friendly beverage) - **Aloo Tikki Chaat** (Veg starter with onion) Each includes: - Dietary tags (veg/non-veg/vegan/Jain) - Ingredient flags (onion, garlic, egg) - Allergen information - Spice level (0-5) - Meat type classification - Popularity score - Pricing ## Next Steps ### 1. Access Sanity Studio Visit your Sanity Studio at: ``` https://nc06prfm.sanity.studio/ ``` ### 2. Add More Menu Items In the Sanity Studio, you can: - Add new dishes - Upload images for dishes - Update prices and availability - Manage allergens and dietary information - Adjust spice levels ### 3. Deploy to Vercel The app is ready to deploy! The environment variables are already configured: - Project ID is hardcoded in the config - Dataset is set to 'production' - API token can be added as `SANITY_API_TOKEN` for mutations ### 4. Test the App Your app now: - Fetches real menu data from Sanity - Filters based on dietary preferences - Shows only dishes that match user restrictions - Displays full ingredient and allergen information ## Managing Content ### Adding New Dishes 1. Go to Sanity Studio 2. Click "Menu Items" 3. Click "Create new" 4. Fill in all fields: - Name, category, description - Price and availability - Dietary flags (isVeg, isVegan, isJain) - Ingredient flags (containsOnion, containsGarlic, containsEgg) - Meat type (if non-veg) - Allergens (select from list) - Spice level (1-5) - Popularity score (for sorting) 5. Publish the document ### Updating Existing Dishes - Edit any field in Sanity Studio - Changes reflect immediately in your app - Use the popularity score to control dish ordering ## Schema Structure ```typescript menuItem { name: string (required) category: 'starter' | 'main' | 'dessert' | 'beverage' description: text price: number (required) availableNow: boolean popularityScore: number (0-100) // Dietary Information isVeg: boolean (required) isVegan: boolean (required) isJain: boolean (required) containsOnion: boolean (required) containsGarlic: boolean (required) containsEgg: boolean (required) meatType: 'chicken' | 'fish' | 'mutton' | 'none' // Allergens and Spices allergens: string[] (array of allergen names) spiceLevel: number (1-5, required) // Additional Details ingredients: string[] (array of ingredient names) image: image (optional) } ``` ## API Usage The app queries Sanity using GROQ: ```typescript // Get all vegetarian dishes *[_type == "menuItem" && isVeg == true] // Get Jain-friendly dishes *[_type == "menuItem" && isJain == true] // Filter by meat type *[_type == "menuItem" && meatType == "chicken"] // Exclude allergens *[_type == "menuItem" && !("dairy" in allergens)] ``` ## Support - Sanity Documentation: https://www.sanity.io/docs - GROQ Query Language: https://www.sanity.io/docs/groq - Sanity Studio: https://www.sanity.io/docs/sanity-studio Your app is now fully functional with real-time content management! 🚀 [V0_FILE]typescriptreact:file="app/preferences/loading.tsx" isMerged="true" export default function Loading() { return (
