Script Vals\n\n- Basic JavaScript/TypeScript functions\n- Can be imported by other vals\n- Example structure:\n\n```typescript\nexport function myFunction() {\n // Your code here\n}\n```\n\n### 2. HTTP Vals\n\n- Create web APIs and endpoints\n- Handle HTTP requests and responses\n- Example structure:\n\n```typescript\nexport default async function (req: Request) {\n return new Response(\"Hello World\");\n}\n```\n\n### 3. Cron Vals\n\n- Run on a schedule\n- Use cron expressions for timing\n- Example structure:\n\n```typescript\nexport default async function () {\n // Scheduled task code\n}\n```\n\n### 4. Email Vals\n\n- Process incoming emails\n- Handle email-based workflows\n- Example structure:\n\n```typescript\nexport default async function (email: Email) {\n // Process email\n}\n```\n\n## Core Guidelines\n\n- Ask clarifying questions when requirements are ambiguous\n- Provide complete, functional solutions rather than skeleton implementations\n- Test your logic against edge cases before presenting the final solution\n- Ensure all code follows Val Town's specific platform requirements\n- If a section of code that you're working on is getting too complex, consider refactoring it into subcomponents\n\n## Code Standards\n\n- Generate code in TypeScript\n- Add appropriate TypeScript types and interfaces for all data structures\n- Prefer official SDKs or libraries than writing API calls directly\n- Ask the user to supply API or library documentation if you are at all unsure about it\n- **Never bake in secrets into the code** - always use environment variables\n- Include comments explaining complex logic (avoid commenting obvious operations)\n- Follow modern ES6+ conventions and functional programming practices if possible\n\n## Val Town Standard Libraries\n\nVal Town provides several hosted services and utility functions.\n\n### Blob Storage\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```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```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```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\nAlways import utilities with version pins to avoid breaking changes:\n```ts\nimport { parseProject, readFile, serveFile } from \"https://esm.town/v/std/utils@85-main/index.ts\";\n```\n\n### Available Utilities\n\n1. **parseProject** - Extract information about the current project from import.meta.url:\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\n2. **readFile** - Read files from within the project:\n```ts\n// Read a file from the project\nconst fileContent = await readFile(\"/frontend/index.html\", import.meta.url);\n```\n\n3. **serveFile** - Serve project files with proper content types:\n```ts\n// Serve a file from the project with proper Content-Type header\napp.get(\"/public/style.css\", c => serveFile(\"/frontend/style.css\", import.meta.url));\n```\n\n4. **listFiles** - List all files in the project:\n```ts\nconst files = await listFiles(import.meta.url);\n```\n\n5. **fetchTranspiledJavaScript** - Fetch and transpile TypeScript to JavaScript:\n```ts\nconst jsCode = await fetchTranspiledJavaScript(\"https://esm.town/v/username/project/path/to/file.ts\");\n```\n\n6. **testServer** - Create a test server for running test suites:\n```ts\nexport default testServer([\n {\n name: \"Feature Tests\",\n tests: [\n {\n name: \"should add numbers correctly\",\n function: () => {\n expect(1 + 1).toBe(2);\n },\n }\n ],\n }\n]);\n```\n\n## Val Town Platform Specifics\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- For AI-generated images, use: `https://maxm-imggenurl.web.val.run/the-description-of-your-image`\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 with `import.meta.url.replace(\"esm.town\", \"val.town\")` 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')` and minimize their use - prefer APIs without 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- For persistence, use Val Town SQLite or Blob storage with `import.meta.url` for keys/table names\n- **React Configuration:** When using React libraries, pin versions with `?deps=react@18.2.0,react-dom@18.2.0` and include the `@jsxImportSource` pragma\n- When facing client-side render issues, check if all React 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│ ├── 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 # 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- Hono is the recommended API framework (similar to Express, Flask, or Sinatra)\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 // Use the serveFile utility to handle content types automatically\n app.get(\"/public/*\", c => serveFile(c.req.path.replace(\"/public\", \"/frontend\"), 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- Be careful with error handling as Hono tends to swallow errors\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### Frontend Best Practices\n- Structure as a standard client-side React app\n- Use SVG for favicons (Val Town only supports text files)\n- Separate components into individual files\n- Access bootstrapped data from `window.__INITIAL_DATA__`\n- Use React 18.2.0 consistently in all imports and the `@jsxImportSource` pragma\n- Follow the React component pattern from the example project\n- Handle API calls properly with proper error catching\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- Follow the queries and migrations pattern from the example\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 - Properly handle CORS if needed for external access","deleted",false,"label",[14],"506abe0e-194a-11f0-bb08-569c3dd06744",["D",1744646741584],"deletedAt","legacyEnvVars","privacy","public","httpPrivacy","description","imageUrl","userId","2de2fbd0-194a-11f0-a58b-59a3b0f07dc7","pinnedFileId","a2f8ead8-aabf-46b8-a1e4-a53864f7ec96","pinPreview","pinMigrated","screenshotVersion","likeCount","orgId","09120083-49ac-4039-afa0-61b5f3039cb1","tursoName","tursoHostname","tursoMeasuredAt","pinned","userPerm","r","valPerm","blobPerm","rw","emailPerm","sqlitePerm","projectPerm","telemetryPerm","user",{"_9":10,"_104":100},"org",{"_9":10,"_98":-5,"_99":100,"_54":55,"_101":102,"_103":42},"branch",{"_36":84,"_11":85,"_23":29,"_86":45,"_87":88,"_89":90,"_91":50,"_92":93,"_94":95,"_96":12,"_97":10},"isOwned",18,"main","projectId","forkedBranchId","f2b37196-17c5-11f0-8a41-569c3dd06744","forkedBranchVersion",3,"forkedProjectPrivacy","forkedProjectId","f2b0e6b0-17c5-11f0-8a41-569c3dd06744","forkedProjectOrgId","69d201b4-10ca-4770-a6d6-a8839b626fda","projectName","userHandle","displayName","avatar","https://img.clerk.com/eyJ0eXBlIjoiZGVmYXVsdCIsImlpZCI6Imluc18yTm10cGhQUklwU0tqZHNiOHNnNGd2ZjJURFUiLCJyaWQiOiJ1c2VyXzJ2ajdVZmpBREJNNFgyMzQ2WFYyaG8zb29MdSJ9","tier","free","canRestrictVals","profileImageUrl","ctx",{"_77":-5,"_138":139,"_140":141,"_142":143,"_144":42,"_145":42,"_146":42,"_147":33,"_148":-5,"_149":-7,"_150":-7,"_151":37,"_152":42,"_153":42,"_154":-5,"_155":42,"_156":42,"_157":42,"_158":-5},"ENV",{"_109":110,"_111":112,"_113":85,"_114":115,"_116":117,"_118":119,"_120":121,"_122":123,"_124":125,"_126":127,"_128":129,"_130":131,"_132":133,"_134":135,"_136":137},"REACT_APP_SENTRY_DSN","https://586020d86f05489db63a554690acf1e9@o1398359.ingest.sentry.io/6724499","RENDER_GIT_COMMIT","a3e067d4463eea85f6334f8e583e8516ae58c4f6","RENDER_GIT_BRANCH","POSTHOG_API_TOKEN","phc_nmoyuAkStEZuUp69rYlg1DZgrIt19Gx0Y4Hwf8tGgJP","POSTHOG_API_HOST","https://wart.val.town","WEB_API_TEMPLATE","https://{val}.web.val.run","APP_URL","https://www.val.town","MODULE_URL","https://esm.town","VANITY_WEB_API_TEMPLATE","https://{label}.val.run/","DENOLS_URL","https://lsp.val.town","NODE_ENV","production","CLOUDFLARE_TURNSTILE_SITE_KEY","0x4AAAAAACtaIZJH7s9rBMZ6","GOOGLE_CLIENT_ID","875989696899-jtsqkhlbdv5jrlsk8631p7ipjg3c6o62.apps.googleusercontent.com","STRIPE_PUBLISHABLE_KEY","pk_live_51N2zvWEpZTTLipIkVEwXrUG9AT0yeOOEYxszarZT1jpsZV58Ly6wlg3SltZpHN26CUalOBmUSY7adQRQiSkCZz2500qSXNkf8Y","API_URL","https://api.val.town","orgs",[],"preferencesKeybindings","default","preferencesTheme","light","preferencesFixers","preferencesCopilot","preferencesSelectionAi","preferencesCloseBrackets","preferencesChatPanelState","preferencesDprint","preferencesDenofmt","notificationCount","flagDenols","isBusinessOrgMember","businessOrgHandle","isBusinessOrgAdmin","isHigherTownieTier","navCollapsed","currentOrgId"]
