These utilities handle file management, project information, and testing.\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@71-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## Val Town Standard Libraries\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## 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- Consider 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",["D",1742929531429],"id","1f5a4a76-09ac-11f0-bbb4-569c3dd06744","OpenTownie_1742929531340",["D",1742929531350],"deletedAt","legacyEnvVars","privacy","public","httpPrivacy","description","imageUrl","9319c175-2593-4f88-ba21-04f2ef7b1c28","pinnedFileId","1fa74e20-09ac-11f0-bbb4-569c3dd06744","pinPreview",true,"pinMigrated","screenshotVersion","likeCount",0,"orgId","d663a026-6449-42f6-9156-1d4a2d64d38c","tursoName","tursoHostname","tursoMeasuredAt","pinned","userPerm","r","valPerm","blobPerm","rw","emailPerm","sqlitePerm","projectPerm","telemetryPerm","user",{"_100":99,"_108":104},"org",{"_100":99,"_101":102,"_103":104,"_18":58,"_105":106,"_107":25},"branch",{"_13":89,"_32":90,"_47":40,"_91":48,"_92":-5,"_93":-5,"_94":-5,"_95":-5,"_96":-5,"_97":49,"_98":99},"isOwned",15,"main","projectId","forkedBranchId","forkedBranchVersion","forkedProjectPrivacy","forkedProjectId","forkedProjectOrgId","projectName","userHandle","dcm31","handle","displayName","Charlie","avatar","https://imagedelivery.net/iHX6Ovru0O7AjmyT5yZRoA/3e904faa-3764-4629-c475-f561a49b0000/square512?exp=1789727199&sig=40263457df6086a40e818da1c1641590b845460b6aa08c1cc60165b3f9c88fca","tier","pro","canRestrictVals","profileImageUrl","branchName","","adoptOrgId",{"_47":48,"_32":49,"_36":158,"_51":-5,"_52":25,"_53":54,"_55":54,"_56":-5,"_57":-5,"_18":58,"_59":60,"_61":62,"_63":-5,"_64":-5,"_65":66,"_67":68,"_69":-5,"_70":-5,"_71":-5,"_72":-5,"_73":74,"_75":74,"_76":77,"_78":77,"_79":77,"_80":74,"_81":74,"_82":159,"_84":160,"_86":161,"_88":25},"tree",[148],"files",[148,149],"counts",{"_138":66,"_139":14,"_140":66,"_141":142,"_143":144},"contents",[131],"upstreamProject","upstreamBranch","emptyEnvVars","flags",[],"hasHttpFiles","grants","orgs","customDomains",{},{"_47":132,"_32":28,"_30":31,"_133":-5,"_39":40,"_38":14,"_134":62,"_36":135,"_13":66,"_33":34,"_35":-5,"_24":25,"_136":-5,"_27":137},"1f67377c-09ac-11f0-bd74-569c3dd06744","parentId","latest",["D",1742929531429],"label",[28],"pulls","branches","forks","envVars",{"_145":66,"_147":66},"connections",{"_145":66,"_146":66},"count","unfilledCount","emptyCount",{"_47":132,"_32":28,"_30":31,"_133":-5,"_39":40,"_38":14,"_134":62,"_36":155,"_13":66,"_33":34,"_35":-5,"_24":25,"_136":-5,"_152":156,"_27":157},{"_47":150,"_32":44,"_30":43,"_133":31,"_39":40,"_38":14,"_134":62,"_36":151,"_13":66,"_33":21,"_35":45,"_24":25,"_136":-5,"_152":153,"_27":154},"1f670964-09ac-11f0-bd74-569c3dd06744",["D",1742929531429],"children",[],[28,44],["D",1742929531429],[149],[28],["D",1742929531350],{"_100":99,"_108":104},{"_100":99,"_101":102,"_103":104,"_18":58,"_105":106,"_107":25},{"_13":89,"_32":90,"_47":40,"_91":48,"_92":-5,"_93":-5,"_94":-5,"_95":-5,"_96":-5,"_97":49,"_98":99},"ctx",{"_82":-5,"_128":195,"_196":197,"_198":199,"_200":25,"_201":25,"_202":25,"_203":62,"_204":-5,"_205":-7,"_206":-7,"_207":66,"_208":25,"_209":25,"_210":-5,"_211":25,"_212":25,"_213":25,"_214":-5},"ENV",{"_166":167,"_168":169,"_170":90,"_171":172,"_173":174,"_175":176,"_177":178,"_179":180,"_181":182,"_183":184,"_185":186,"_187":188,"_189":190,"_191":192,"_193":194},"REACT_APP_SENTRY_DSN","https://586020d86f05489db63a554690acf1e9@o1398359.ingest.sentry.io/6724499","RENDER_GIT_COMMIT","71c1b20804b3232a7e513be260cfffc1932a9e97","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",[],"preferencesKeybindings","default","preferencesTheme","light","preferencesFixers","preferencesCopilot","preferencesSelectionAi","preferencesCloseBrackets","preferencesChatPanelState","preferencesDprint","preferencesDenofmt","notificationCount","flagDenols","isBusinessOrgMember","businessOrgHandle","isBusinessOrgAdmin","isHigherTownieTier","navCollapsed","currentOrgId"]
