Let errors bubble up\n with full context\n- **Environment Variables:** Use `Deno.env.get('keyname')` when you need to, but\n generally prefer APIs that don't require keys\n- **Imports:** Use `https://esm.sh` for npm and Deno dependencies to ensure\n compatibility on server and browser\n- **Storage Strategy:** Only use backend storage if explicitly required; prefer\n simple static client-side sites\n- **React Configuration:** When using React libraries, pin versions with\n `?deps=react@18.2.0,react-dom@18.2.0` and start the file with\n `/** @jsxImportSource https://esm.sh/react@18.2.0 */`\n- Ensure all React dependencies and sub-dependencies are pinned to the same\n version\n- **Styling:** Default to using TailwindCSS via\n `` unless otherwise\n specified\n\n## Project Structure and Design Patterns\n\n### Recommended Directory Structure\n\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\n files:\n ```ts\n import {\n readFile,\n serveFile,\n } 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\n 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\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\n 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\n `export default app.fetch // This is the entry point for HTTP vals`\n",[192],"f4c53bfe-aaff-11f0-b516-0224a6c84d84",".vtignore","f4c53c8a-aaff-11f0-b516-0224a6c84d84",11,["D",1760667674835],".git\n.vscode\n.cursorrules\n.DS_Store\nnode_modules\nvendor",[199],"pulls","branches","forks","envVars",{"_212":41,"_214":41},"connections",{"_212":41,"_213":41},"count","unfilledCount","emptyCount",{"_18":198,"_20":199,"_132":200,"_133":-5,"_134":67,"_135":201,"_137":37,"_22":249,"_64":41,"_140":99,"_142":203,"_144":26,"_145":-5,"_225":250,"_88":251},{"_18":191,"_20":192,"_132":193,"_133":-5,"_134":67,"_135":194,"_137":37,"_22":246,"_64":150,"_140":99,"_142":196,"_144":26,"_145":-5,"_225":247,"_88":248},{"_18":184,"_20":185,"_132":186,"_133":-5,"_134":67,"_135":187,"_137":37,"_22":243,"_64":150,"_140":99,"_142":189,"_144":26,"_145":-5,"_225":244,"_88":245},{"_18":177,"_20":178,"_132":179,"_133":-5,"_134":67,"_135":65,"_137":37,"_22":240,"_64":181,"_140":99,"_142":182,"_144":26,"_145":-5,"_225":241,"_88":242},{"_18":170,"_20":171,"_132":172,"_133":-5,"_134":67,"_135":173,"_137":37,"_22":237,"_64":150,"_140":99,"_142":175,"_144":26,"_145":-5,"_225":238,"_88":239},{"_18":161,"_20":162,"_132":163,"_133":-5,"_134":67,"_135":164,"_137":37,"_22":234,"_64":166,"_140":167,"_142":168,"_144":26,"_145":-5,"_225":235,"_88":236},{"_18":155,"_20":156,"_132":157,"_133":-5,"_134":67,"_135":150,"_137":37,"_22":231,"_64":41,"_140":152,"_142":159,"_144":26,"_145":-5,"_225":232,"_88":233},{"_18":147,"_20":148,"_132":149,"_133":-5,"_134":67,"_135":150,"_137":37,"_22":228,"_64":41,"_140":152,"_142":153,"_144":26,"_145":-5,"_225":229,"_88":230},{"_18":131,"_20":21,"_132":35,"_133":-5,"_134":67,"_135":136,"_137":37,"_22":224,"_64":139,"_140":141,"_142":143,"_144":26,"_145":-5,"_225":226,"_88":227},["D",1760668120779],"children",[],[21],["D",1758426923872],[],[148],["D",1758426923872],[],[156],["D",1760668308041],[],[162],["D",1760668120781],[],[171],["D",1773558423728],[],[178],["D",1760668120791],[],[185],["D",1760668120788],[],[192],["D",1760667674835],[],[199],["D",1758426923872],{"_16":17,"_86":82},{"_16":17,"_80":-5,"_81":82,"_32":33,"_83":84,"_85":26},{"_64":65,"_20":66,"_18":67,"_68":19,"_69":70,"_71":72,"_73":28,"_74":75,"_76":77,"_78":21,"_79":17},"ctx",{"_57":-5,"_109":289,"_290":291,"_292":293,"_294":26,"_295":26,"_296":26,"_297":37,"_298":-5,"_299":-7,"_300":-7,"_301":41,"_302":26,"_303":26,"_304":-5,"_305":26,"_306":26,"_307":26,"_308":-5},"ENV",{"_260":261,"_262":263,"_264":66,"_265":266,"_267":268,"_269":270,"_271":272,"_273":274,"_275":276,"_277":278,"_279":280,"_281":282,"_283":284,"_285":286,"_287":288},"REACT_APP_SENTRY_DSN","https://586020d86f05489db63a554690acf1e9@o1398359.ingest.sentry.io/6724499","RENDER_GIT_COMMIT","e87eb04e707cf64e7e532c8e8ec395f209e17f15","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"]
