HTTP Trigger\n\n- Create web APIs and endpoints\n- Handle HTTP requests and responses\n- Example structure:\n\n```ts\nexport default async function (req: Request) {\n return new Response(\"Hello World\");\n}\n```\n\nFiles that are HTTP triggers have http in their name like `foobar.http.tsx`\n\n### 2. Cron Triggers\n\n- Run on a schedule\n- Use cron expressions for timing\n- Example structure:\n\n```ts\nexport default async function () {\n // Scheduled task code\n}\n```\n\nFiles that are Cron triggers have cron in their name like `foobar.cron.tsx`\n\n### 3. Email Triggers\n\n- Process incoming emails\n- Handle email-based workflows\n- Example structure:\n\n```ts\nexport default async function (email: Email) {\n // Process email\n}\n```\n\nFiles that are Email triggers have email in their name like `foobar.email.tsx`\n\n\n## Val Town Standard Libraries\n\nVal Town provides several hosted services and utility functions.\n\n### Blob Storage\n\n```ts\nimport { blob } from \"https://esm.town/v/std/blob\";\nawait blob.setJSON(\"myKey\", { hello: \"world\" });\nlet blobDemo = await blob.getJSON(\"myKey\");\nlet appKeys = await blob.list(\"app_\");\nawait blob.delete(\"myKey\");\n```\n\n### SQLite\n\n```ts\nimport { sqlite } from \"https://esm.town/v/stevekrouse/sqlite\";\nconst TABLE_NAME = 'todo_app_users_2';\n// Create table - do this before usage and change table name when modifying schema\nawait sqlite.execute(`CREATE TABLE IF NOT EXISTS ${TABLE_NAME} (\n id INTEGER PRIMARY KEY AUTOINCREMENT,\n name TEXT NOT NULL\n)`);\n// Query data\nconst result = await sqlite.execute(`SELECT * FROM ${TABLE_NAME} WHERE id = ?`, [1]);\n```\n\nNote: When changing a SQLite table's schema, change the table's name (e.g., add _2 or _3) to create a fresh table.\n\n### OpenAI\n\n```ts\nimport { OpenAI } from \"https://esm.town/v/std/openai\";\nconst openai = new OpenAI();\nconst completion = await openai.chat.completions.create({\n messages: [\n { role: \"user\", content: \"Say hello in a creative way\" },\n ],\n model: \"gpt-4o-mini\",\n max_tokens: 30,\n});\n```\n\n### Email\n\n```ts\nimport { email } from \"https://esm.town/v/std/email\";\n// By default emails the owner of the val\nawait email({ \n subject: \"Hi\", \n text: \"Hi\", \n html: \"

Hi

\"\n});\n```\n\n## Val Town Utility Functions\n\nVal Town provides several utility functions to help with common project tasks.\n\n### Importing Utilities\n\nAlways import utilities with version pins to avoid breaking changes:\n\n```ts\nimport { parseProject, readFile, serveFile } from \"https://esm.town/v/std/utils@85-main/index.ts\";\n```\n\n### Available Utilities\n\n\n#### **serveFile** - Serve project files with proper content types\n\nFor example, in Hono:\n\n```ts\n// serve all files in frontend/ and shared/\napp.get(\"/frontend/*\", c => serveFile(c.req.path, import.meta.url));\napp.get(\"/shared/*\", c => serveFile(c.req.path, import.meta.url));\n```\n\n#### **readFile** - Read files from within the project:\n\n```ts\n// Read a file from the project\nconst fileContent = await readFile(\"/frontend/index.html\", import.meta.url);\n```\n\n#### **listFiles** - List all files in the project\n\n```ts\nconst files = await listFiles(import.meta.url);\n```\n\n#### **parseProject** - Extract information about the current project from import.meta.url\n\nThis is useful for including info for linking back to a val, ie in \"view source\" urls:\n\n```ts\nconst projectVal = parseProject(import.meta.url);\nconsole.log(projectVal.username); // Owner of the project\nconsole.log(projectVal.name); // Project name\nconsole.log(projectVal.version); // Version number\nconsole.log(projectVal.branch); // Branch name\nconsole.log(projectVal.links.self.project); // URL to the project page\n```\n\nHowever, it's *extremely importing* to note that `parseProject` and other Standard Library utilities ONLY RUN ON THE SERVER.\nIf you need access to this data on the client, run it in the server and pass it to the client by splicing it into the HTML page\nor by making an API request for it.\n\n## Val Town Platform Specifics\n\n- **Redirects:** Use `return new Response(null, { status: 302, headers: { Location: \"/place/to/redirect\" }})` instead of `Response.redirect` which is broken\n- **Images:** Avoid external images or base64 images. Use emojis, unicode symbols, or icon fonts/libraries instead\n- **AI Image:** To inline generate an AI image use: `

`\n- **Storage:** DO NOT use the Deno KV module for storage\n- **Browser APIs:** DO NOT use the `alert()`, `prompt()`, or `confirm()` methods\n- **Weather Data:** Use open-meteo for weather data (doesn't require API keys) unless otherwise specified\n- **View Source:** Add a view source link by importing & using `import.meta.url.replace(\"ems.sh\", \"val.town)\"` (or passing this data to the client) and include `target=\"_top\"` attribute\n- **Error Debugging:** Add `` to HTML to capture client-side errors\n- **Error Handling:** Only use try...catch when there's a clear local resolution; Avoid catches that merely log or return 500s. Let errors bubble up with full context\n- **Environment Variables:** Use `Deno.env.get('keyname')` when you need to, but generally prefer APIs that don't require keys\n- **Imports:** Use `https://esm.sh` for npm and Deno dependencies to ensure compatibility on server and browser\n- **Storage Strategy:** Only use backend storage if explicitly required; prefer simple static client-side sites\n- **React Configuration:** When using React libraries, pin versions with `?deps=react@18.2.0,react-dom@18.2.0` and start the file with `/** @jsxImportSource https://esm.sh/react@18.2.0 */`\n- Ensure all React dependencies and sub-dependencies are pinned to the same version\n- **Styling:** Default to using TailwindCSS via `` unless otherwise specified\n\n## Project Structure and Design Patterns\n\n### Recommended Directory Structure\n```\n├── backend/\n│ ├── database/\n│ │ ├── migrations.ts # Schema definitions\n│ │ ├── queries.ts # DB query functions\n│ │ └── README.md\n│ └── routes/ # Route modules\n│ ├── [route].ts\n│ └── static.ts # Static file serving\n│ ├── index.ts # Main entry point\n│ └── README.md\n├── frontend/\n│ ├── components/\n│ │ ├── App.tsx\n│ │ └── [Component].tsx\n│ ├── favicon.svg\n│ ├── index.html # Main HTML template\n│ ├── index.tsx # Frontend JS entry point\n│ ├── README.md\n│ └── style.css\n├── README.md\n└── shared/\n ├── README.md\n └── utils.ts # Shared types and functions\n```\n\n### Backend (Hono) Best Practices\n\n- Hono is the recommended API framework\n- Main entry point should be `backend/index.ts`\n- **Static asset serving:** Use the utility functions to read and serve project files:\n ```ts\n import { readFile, serveFile } from \"https://esm.town/v/std/utils@85-main/index.ts\";\n \n // serve all files in frontend/ and shared/\n app.get(\"/frontend/*\", c => serveFile(c.req.path, import.meta.url));\n app.get(\"/shared/*\", c => serveFile(c.req.path, import.meta.url));\n \n // For index.html, often you'll want to bootstrap with initial data\n app.get(\"/\", async c => {\n let html = await readFile(\"/frontend/index.html\", import.meta.url);\n \n // Inject data to avoid extra round-trips\n const initialData = await fetchInitialData();\n const dataScript = ``;\n \n html = html.replace(\"\", `${dataScript}`);\n return c.html(html);\n });\n ```\n- Create RESTful API routes for CRUD operations\n- Always include this snippet at the top-level Hono app to re-throwing errors to see full stack traces:\n ```ts\n // Unwrap Hono errors to see original error details\n app.onError((err, c) => {\n throw err;\n });\n ```\n\n### Database Patterns\n- Run migrations on startup or comment out for performance\n- Change table names when modifying schemas rather than altering\n- Export clear query functions with proper TypeScript typing\n\n## Common Gotchas and Solutions\n\n1. **Environment Limitations:** \n - Val Town runs on Deno in a serverless context, not Node.js\n - Code in `shared/` must work in both frontend and backend environments\n - Cannot use `Deno` keyword in shared code\n - Use `https://esm.sh` for imports that work in both environments\n\n2. **SQLite Peculiarities:**\n - Limited support for ALTER TABLE operations\n - Create new tables with updated schemas and copy data when needed\n - Always run table creation before querying\n\n3. **React Configuration:**\n - All React dependencies must be pinned to 18.2.0\n - Always include `@jsxImportSource https://esm.sh/react@18.2.0` at the top of React files\n - Rendering issues often come from mismatched React versions\n\n4. **File Handling:**\n - Val Town only supports text files, not binary\n - Use the provided utilities to read files across branches and forks\n - For files in the project, use `readFile` helpers\n\n5. **API Design:**\n - `fetch` handler is the entry point for HTTP vals\n - Run the Hono app with `export default app.fetch // This is the entry point for HTTP vals`\n\n",[],[254],{"_105":262,"_96":263,"_157":264,"_159":-5,"_160":142,"_161":265,"_163":119,"_107":266,"_101":267,"_165":230,"_167":268,"_168":22,"_169":-5,"_170":269,"_99":270},"d4554fea-bf30-11f0-8846-42dde27851f2","CLAUDE.md","134dfeb2-bf2d-11f0-92cf-42dde27851f2",10,["D",1762887689009],1,"⏺ Building a Val Town MVC Application with React Frontend\n\nThis guide provides step-by-step instructions for scaffolding a Val Town application following the\nproven MVC architecture pattern from the proposalizer project.\n\nArchitecture Overview\n\nproject/\n├── main.http.tsx # Entry point, Hono app initialization\n├── backend/\n│ ├── routes/ # HTTP layer (thin wrappers)\n│ │ ├── api/ # RESTful API endpoints\n│ │ ├── tasks/ # Webhook handlers\n│ │ ├── views/ # User-facing pages\n│ │ └── authCheck.ts # Authentication middleware\n│ ├── controllers/ # Business logic and orchestration\n│ ├── services/ # External API integrations\n│ └── utils/ # Backend-only utilities (optional)\n├── frontend/\n│ ├── index.html # HTML shell with React mount point\n│ ├── index.tsx # React entry point\n│ └── components/ # React components\n│ └── App.tsx # Main application component\n└── shared/\n├── types.ts # Shared TypeScript interfaces\n└── utils.ts # Browser + Deno compatible utilities\n\nPhase 1: Setup Entry Point and Core Infrastructure\n\nStep 1: Create main.http.tsx\n\nPurpose: Val Town HTTP entry point that initializes Hono framework, mounts routes, serves static\nassets\n\nInstructions:\n\n1. Import Hono framework:\n import { Hono } from \"npm:hono@4\";\n2. Create Hono app instance:\n const app = new Hono();\n3. Add error handler (unwraps errors for better stack traces):\n app.onError((err, c) => {\n throw err;\n });\n4. Add global authentication middleware (before mounting routes):\n\n\n - Define array of protected route prefixes (e.g., [\"/api\", \"/tasks\"])\n - Define array of public exceptions (e.g., [\"/api/health\"])\n - Use middleware to check if path matches protected prefix and is not in exceptions\n - If protected, call webhookAuth middleware from authCheck.ts\n\n5. Add health check endpoint:\n app.get(\"/api/health\", (c) => c.json({ status: \"ok\" }));\n6. Mount route modules (will create these later):\n import api from \"./backend/routes/api/index.ts\";\n import tasks from \"./backend/routes/tasks/index.ts\";\n\napp.route(\"/api\", api);\napp.route(\"/tasks\", tasks); 7. Serve frontend static files: - Import Val Town's serveFile utility - Add catch-all route app.get(\"_\", ...) - Map requests to frontend directory: - / → frontend/index.html - /index.js → frontend/index.tsx (Val Town auto-transpiles) - /components/_ → frontend/components/\\* - Use serveFile() to return file contents 8. Export for Val Town:\nexport default app;\n\nStep 2: Create Authentication Middleware\n\nFile: backend/routes/authCheck.ts\n\nPurpose: Shared secret authentication using X-API-KEY header\n\nInstructions:\n\n1. Import Hono types (Context, Next)\n2. Create webhookAuth function:\n\n\n - Get WEBHOOK_SECRET from environment\n - If not set, log warning and allow request (dev mode)\n - Extract X-API-KEY header from request\n - Compare with WEBHOOK_SECRET\n - If invalid, return 401 with error message\n - If valid, call await next()\n\n3. Export the middleware function\n\nPhase 2: Build Service Layer (External APIs)\n\nStep 3: Create Service Files\n\nLocation: backend/services/\n\nPurpose: Handle all external API calls, return standardized responses\n\nFor Each External Service:\n\n1. Simple service (single file):\n\n\n - Create backend/services/[serviceName]Service.ts\n - Import client library (use npm: prefix)\n - Initialize client with API key from environment\n - Export typed functions that:\n - Make API calls\n - Wrap in try/catch\n - Return { success: boolean, data: any | null, error: string | null }\n\n2. Complex service (directory):\n\n\n - Create backend/services/[serviceName]/ directory\n - Create index.ts:\n - Initialize shared client\n - Re-export all functions from feature files\n - Create feature files (e.g., pages.ts, databases.ts):\n - Import shared client from ./index.ts\n - Export typed functions following same pattern\n\nExample Service Function Structure:\nexport async function fetchSomething(id: string) {\ntry {\nconst result = await client.get(id);\nreturn { success: true, data: result, error: null };\n} catch (err: any) {\nreturn { success: false, data: null, error: err.message };\n}\n}\n\nKey Rules:\n\n- NEVER throw errors, always return error objects\n- Store API keys in environment variables\n- One client instance per service (initialize once, reuse)\n- All functions return { success, data, error } structure\n\nPhase 3: Build Controller Layer (Business Logic)\n\nStep 4: Create Controllers\n\nLocation: backend/controllers/\n\nPurpose: Orchestrate workflows, validate input, call services, transform data\n\nOrganization Strategy:\n\n- Group by workflow domain (e.g., pageController.ts, emailController.ts, publishingController.ts)\n- Keep files under 500 lines - split if larger\n- One controller exports multiple related functions\n\nFor Each Controller Function:\n\n1. Input validation:\n if (!requiredParam || typeof requiredParam !== 'expectedType') {\n return {\n success: false,\n data: null,\n error: \"Invalid input\",\n details: \"Description of what's wrong\"\n };\n }\n2. Call service layer:\n const result = await someService.fetchData(id);\n3. Handle service errors:\n if (!result.success) {\n return {\n success: false,\n data: null,\n error: \"Higher-level error message\",\n details: result.error\n };\n }\n4. Orchestrate multiple service calls (if needed):\n const data1 = await service1.fetch();\n const data2 = await service2.fetch(data1.data.id);\n5. Transform/filter data (if needed):\n\n\n - Remove sensitive properties\n - Combine data from multiple sources\n - Format for frontend consumption\n\n6. Return standardized response:\n return {\n success: true,\n data: transformedData,\n error: null\n };\n\nKey Rules:\n\n- NEVER make HTTP responses (controllers are HTTP-agnostic)\n- NEVER call external APIs directly (use services)\n- ALWAYS return { success, data, error, details? } structure\n- Validate ALL inputs at the top\n- Log important steps with descriptive messages\n\nPhase 4: Build Route Layer (HTTP Interface)\n\nStep 5: Create Route Modules\n\nLocation: backend/routes/api/, backend/routes/tasks/, backend/routes/views/\n\nPurpose: Extract HTTP request data, call controllers, format HTTP responses\n\nFor Each Route Module:\n\n1. Create route file (e.g., backend/routes/api/pages.ts):\n import { Hono } from \"npm:hono@4\";\n import \\* as controller from \"../../controllers/[name]Controller.ts\";\n\nconst pages = new Hono(); 2. For API endpoints (/api/_): - Extract params: c.req.param('id') - Extract query: c.req.query('param') - Extract body: await c.req.json() - Call controller with extracted data - Map controller response to HTTP:\nif (!result.success) {\nreturn c.json({ error: result.error, details: result.details }, 400);\n}\nreturn c.json(result.data); 3. For webhook endpoints (/tasks/_): - Wrap body parsing in try/catch - Check for two payload formats:\n// Notion automation format (check first)\nif (body?.data?.object === \"page\" && body?.data?.id) {\npageId = body.data.id;\n}\n// Simple API format (fallback)\nelse if (body?.pageId) {\npageId = body.pageId;\n} - Validate required fields - Call controller - Return success/error JSON (webhooks need quick response) 4. Export route module:\nexport default pages;\n\nStep 6: Create Route Index Files\n\nFor each route directory (api/, tasks/, views/):\n\n1. Create index.ts:\n import { Hono } from \"npm:hono@4\";\n import moduleA from \"./moduleA.ts\";\n import moduleB from \"./moduleB.ts\";\n\nconst api = new Hono();\n\napi.route(\"/moduleA\", moduleA);\napi.route(\"/moduleB\", moduleB);\n\nexport default api; 2. This creates final URL structure: - Mount in main: app.route(\"/api\", api) - Route in index: api.route(\"/pages\", pages) - Route in module: pages.get(\"/:id\", ...) - Final URL: /api/pages/:id\n\nKey Rules:\n\n- Routes are THIN wrappers (5-20 lines per endpoint)\n- NO business logic in routes\n- NEVER call services directly from routes\n- Map controller success/error to HTTP status codes\n- Return proper HTTP responses with status codes\n\nPhase 5: Build Frontend (React)\n\nStep 7: Create HTML Shell\n\nFile: frontend/index.html\n\nInstructions:\n\n1. Create basic HTML5 structure with:\n\n\n - \n - \n - for your app\n\n2. Load Pico CSS (classless framework):\n<link rel=\"stylesheet\" href=\"https://cdn.jsdelivr.net/npm/@picocss/pico@2/css/pico.min.css\">\n3. Add custom styles in <style>:\n #root > div {\n padding-block: var(--pico-block-spacing-vertical);\n }\n4. Add React mount point in body:\n<body>\n <div id=\"root\"></div>\n <script type=\"module\" src=\"/index.js\"></script>\n</body>\n\nStep 8: Create React Entry Point\n\nFile: frontend/index.tsx\n\nInstructions:\n\n1. Import React with pinned version and jsxImportSource:\n /\\*_ @jsxImportSource https://esm.sh/react@18.2.0 _/\n import React from \"https://esm.sh/react@18.2.0?deps=react@18.2.0\";\n import ReactDOM from \"https://esm.sh/react-dom@18.2.0/client?deps=react@18.2.0\";\n2. Import App component:\n import App from \"./components/App.tsx\";\n3. Create root and render:\n const root = ReactDOM.createRoot(document.getElementById(\"root\")!);\n root.render(<App />);\n\nStep 9: Create React Components\n\nFile: frontend/components/App.tsx\n\nInstructions:\n\n1. Add jsxImportSource pragma and import React\n2. Create App component with state:\n export default function App() {\n const [data, setData] = React.useState<any>(null);\n const [loading, setLoading] = React.useState(false);\n const [error, setError] = React.useState<string | null>(null);\n\n\n // Component logic\n\n} 3. Fetch data from API (optional):\nReact.useEffect(() => {\nasync function fetchData() {\nsetLoading(true);\ntry {\nconst response = await fetch('/api/your-endpoint');\nconst result = await response.json();\nsetData(result);\n} catch (err: any) {\nsetError(err.message);\n} finally {\nsetLoading(false);\n}\n}\nfetchData();\n}, []); 4. Render with semantic HTML (Pico CSS):\nreturn (\n<main>\n<h1>App Title</h1>\n\n {loading && <p aria-busy=\"true\">Loading...</p>}\n\n {error && <mark>Error: {error}</mark>}\n\n {data && (\n <article>\n {/* Your content */}\n </article>\n )}\n\n <button disabled={loading} aria-busy={loading}>\n Action\n </button>\n </main>\n\n); 5. Use semantic HTML elements (no CSS classes): - <main>, <article>, <section> for layout - <h1>-<h6> for headings - <button> for actions - <input>, <textarea>, <select> for forms - <mark> for errors - <kbd> for tags/badges - aria-busy=\"true\" for loading states on buttons\n\nCreating Additional Components:\n\n1. Create frontend/components/ComponentName.tsx\n2. Add jsxImportSource pragma and React import\n3. Export function component\n4. Import and use in App.tsx\n\nKey Rules:\n\n- ALWAYS pin React to 18.2.0 with full version string\n- ALWAYS use jsxImportSource pragma in every component file\n- Use semantic HTML only (NO CSS classes)\n- Handle loading and error states\n- Fetch from /api/\\* routes for dynamic data\n\nPhase 6: Shared Code\n\nStep 10: Create Shared Types\n\nFile: shared/types.ts\n\nPurpose: TypeScript interfaces used by both frontend and backend\n\nInstructions:\n\n1. Define data structure interfaces:\n export interface YourDataType {\n id: string;\n name: string;\n // ... other fields\n }\n2. Define API request/response interfaces:\n export interface ApiResponse<T> {\n success: boolean;\n data: T | null;\n error: string | null;\n details?: string;\n }\n3. Define common types:\n export type Status = \"draft\" | \"published\" | \"archived\";\n\nStep 11: Create Shared Utilities\n\nFile: shared/utils.ts\n\nPurpose: Pure functions that work in both browser and Deno\n\nInstructions:\n\n1. Only use standard JavaScript/TypeScript (no Deno or Node APIs)\n2. Create pure utility functions:\n export function formatDate(dateString: string): string {\n // Format logic using standard Date API\n }\n3. Export functions with clear names and JSDoc comments\n\nFor Backend-Only Utils:\n\n- Create backend/utils/ for utilities that need Deno APIs\n- Examples: crypto, logging, file system operations\n\nPhase 7: Environment Variables\n\nStep 12: Configure Environment\n\nRequired Environment Variables:\n\n1. Authentication:\n\n\n - WEBHOOK_SECRET - Shared secret for API authentication\n\n2. External Service API Keys:\n\n\n - [SERVICE_NAME]_API_KEY - For each external service\n\n3. Application-Specific Config:\n\n\n - Any app-specific configuration values\n\nAccess in code:\nconst apiKey = Deno.env.get('SERVICE_API_KEY');\n\nPhase 8: Testing Your Setup\n\nStep 13: Verify Each Layer\n\nTest Order:\n\n1. Services: Can you call external APIs and get data back?\n\n\n - Create simple test controller that calls service\n - Log the result\n - Verify service returns { success, data, error } structure\n\n2. Controllers: Does validation and orchestration work?\n\n\n - Test with valid and invalid inputs\n - Verify error messages are helpful\n - Check that multiple service calls work together\n\n3. Routes: Do HTTP endpoints return correct responses?\n\n\n - Test with curl or Postman\n - Verify status codes (200, 400, 401, 500)\n - Check response format\n\n4. Frontend: Does the UI render and fetch data?\n\n\n - Open in browser\n - Check console for errors\n - Verify data loads from API\n - Test user interactions\n\nCommon Patterns Reference\n\nError Handling Flow\n\nService returns error:\n{ success: false, data: null, error: \"API call failed\" }\n\nController adds context:\n{ success: false, data: null, error: \"Failed to create resource\", details: \"API call failed\" }\n\nRoute maps to HTTP:\nreturn c.json({ error: result.error, details: result.details }, 500);\n\nData Flow Example\n\nUser Request → Route extracts pageId from URL → Controller validates pageId, calls service →\nService fetches from external API → Controller filters sensitive data → Route returns JSON response\n\nWebhook Handler Pattern\n\n// Extract pageId from two possible formats\nlet pageId: string | undefined;\n\nif (body?.data?.object === \"page\" && body?.data?.id) {\npageId = body.data.id; // Notion automation format\n} else if (body?.pageId) {\npageId = body.pageId; // Simple format\n}\n\nif (!pageId) {\nreturn c.json({ error: \"Missing pageId\" }, 400);\n}\n\n// Process and return quickly\nconst result = await controller.process(pageId);\nreturn c.json({ status: \"success\", data: result.data });\n\nArchitecture Checklist\n\nBefore you're done, verify:\n\n- ✅ main.http.tsx exports Hono app with mounted routes\n- ✅ Authentication middleware protects /api/_ and /tasks/_\n- ✅ All services return { success, data, error } structure\n- ✅ All controllers return { success, data, error, details? } structure\n- ✅ Routes are thin wrappers (no business logic)\n- ✅ Controllers never make HTTP responses\n- ✅ Services handle all external API calls\n- ✅ Frontend uses React 18.2.0 with pinned versions\n- ✅ Every React file has jsxImportSource pragma\n- ✅ Shared types are defined in shared/types.ts\n- ✅ Environment variables are used for secrets\n- ✅ Frontend uses semantic HTML with Pico CSS\n\nKey Principles\n\n1. Strict layering: Route → Controller → Service (never skip)\n2. Standardized responses: Every function returns same structure\n3. No exceptions: Return error objects, don't throw\n4. Thin routes: Just HTTP concerns, no logic\n5. Smart controllers: All business logic lives here\n6. Dumb services: Just API calls, no decisions\n7. Semantic HTML: No CSS classes, use proper elements\n8. Pinned dependencies: Always specify exact versions\n",[],[263],{"_105":272,"_96":273,"_157":274,"_159":-5,"_160":142,"_161":275,"_163":119,"_107":276,"_101":32,"_165":230,"_167":277,"_168":22,"_169":-5,"_170":278,"_99":279},"dbe14dfe-bf2b-11f0-bc0d-42dde27851f2","deno.json","dbe15006-bf2b-11f0-bc0d-42dde27851f2",6,["D",1762885554155],"{\n \"$schema\": \"https://raw.githubusercontent.com/denoland/deno/98f62cee78e85bfc47c62ed703777c6bc8794f1c/cli/schemas/config-file.v1.json\",\n \"lock\": false,\n \"compilerOptions\": {\n \"noImplicitAny\": false,\n \"strict\": true,\n \"types\": [\"https://www.val.town/types/valtown.d.ts\"],\n \"lib\": [\n \"dom\",\n \"dom.iterable\",\n \"dom.asynciterable\",\n \"deno.ns\",\n \"deno.unstable\"\n ]\n },\n \"lint\": {\n \"include\": [\"deno:/https/esm.town/**/*\"],\n \"rules\": {\n \"exclude\": [\"no-explicit-any\"]\n }\n },\n \"node_modules_dir\": false,\n \"experimental\": {\n \"unstable-node-globals\": true,\n \"unstable-temporal\": true,\n \"unstable-worker-options\": true,\n \"unstable-sloppy-imports\": true\n }\n}",[],[273],{"_105":281,"_96":100,"_157":117,"_159":-5,"_160":142,"_161":282,"_163":22,"_107":283,"_101":284,"_165":285,"_167":286,"_168":22,"_169":287,"_170":288,"_99":289},"d9a6335e-bf32-11f0-8c0a-42dde27851f2",24,["D",1762888556918],3,"http","import { Hono } from \"npm:hono@4\";\nimport { serveFile, readFile } from \"https://esm.town/v/std/utils@85-main/index.ts\";\nimport api from \"./backend/routes/api/index.ts\";\n\nconst app = new Hono();\n\n// Unwrap Hono errors to see original error details\napp.onError((err) => {\n throw err;\n});\n\n// Health check endpoint\napp.get(\"/api/health\", (c) => c.json({ status: \"ok\" }));\n\n// Mount API routes\napp.route(\"/api\", api);\n\n// Map /frontend/index.js to /frontend/index.tsx (Val Town auto-transpiles)\napp.get(\"/frontend/index.js\", () => serveFile(\"/frontend/index.tsx\", import.meta.url));\n\n// Map /frontend/components/*.js to /frontend/components/*.tsx\napp.get(\"/frontend/components/:file\", c => {\n const file = c.req.param('file');\n const tsxFile = file.replace('.js', '.tsx');\n return serveFile(`/frontend/components/${tsxFile}`, import.meta.url);\n});\n\n// Serve other frontend files\napp.get(\"/frontend/*\", c => serveFile(c.req.path, import.meta.url));\n\n// Serve root index.html\napp.get(\"/\", async c => {\n const html = await readFile(\"/frontend/index.html\", import.meta.url);\n return c.html(html);\n});\n\nexport default app.fetch;\n","buckanacre",[],[100],{"_105":291,"_96":292,"_157":293,"_159":-5,"_160":142,"_161":294,"_163":119,"_107":295,"_101":229,"_165":285,"_167":296,"_168":22,"_169":-5,"_170":297,"_99":298},"450c70c4-bf31-11f0-9c54-42dde27851f2","main.ts","b30f9066-bf2b-11f0-87d9-42dde27851f2",11,["D",1762887878114],"// Learn more: https://docs.val.town/vals/http/\nexport default async function (req: Request): Promise<Response> {\n const html = `\n <!DOCTYPE html>\n <html>\n <head>\n <title>Buck an Acre\n \n \n \n
