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",[202],"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",[209],"pulls","branches","forks","envVars",{"_222":62,"_224":62},"connections",{"_222":62,"_223":62},"count","unfilledCount","emptyCount",{"_43":208,"_32":209,"_30":210,"_152":-5,"_41":42,"_40":211,"_154":58,"_38":259,"_13":62,"_33":20,"_35":213,"_24":25,"_159":-5,"_235":260,"_27":261},{"_43":201,"_32":202,"_30":203,"_152":-5,"_41":42,"_40":204,"_154":58,"_38":256,"_13":164,"_33":20,"_35":206,"_24":25,"_159":-5,"_235":257,"_27":258},{"_43":194,"_32":195,"_30":196,"_152":-5,"_41":42,"_40":197,"_154":58,"_38":253,"_13":164,"_33":20,"_35":199,"_24":25,"_159":-5,"_235":254,"_27":255},{"_43":186,"_32":187,"_30":188,"_152":-5,"_41":42,"_40":189,"_154":25,"_38":250,"_13":191,"_33":20,"_35":192,"_24":25,"_159":-5,"_235":251,"_27":252},{"_43":179,"_32":180,"_30":181,"_152":-5,"_41":42,"_40":182,"_154":58,"_38":247,"_13":164,"_33":20,"_35":184,"_24":25,"_159":-5,"_235":248,"_27":249},{"_43":175,"_32":28,"_30":31,"_152":-5,"_41":42,"_40":14,"_154":58,"_38":244,"_13":177,"_33":34,"_35":37,"_24":25,"_159":-5,"_235":245,"_27":246},{"_43":169,"_32":170,"_30":171,"_152":-5,"_41":42,"_40":164,"_154":58,"_38":241,"_13":62,"_33":166,"_35":173,"_24":25,"_159":-5,"_235":242,"_27":243},{"_43":161,"_32":162,"_30":163,"_152":-5,"_41":42,"_40":164,"_154":58,"_38":238,"_13":62,"_33":166,"_35":167,"_24":25,"_159":-5,"_235":239,"_27":240},{"_43":151,"_32":45,"_30":56,"_152":-5,"_41":42,"_40":153,"_154":58,"_38":234,"_13":156,"_33":157,"_35":158,"_24":25,"_159":-5,"_235":236,"_27":237},["D",1760668120779],"children",[],[45],["D",1758426923872],[],[162],["D",1758426923872],[],[170],["D",1760668308041],[],[28],["D",1760668120781],[],[180],["D",1760668198328],[],[187],["D",1760668120791],[],[195],["D",1760668120788],[],[202],["D",1760667674835],[],[209],["D",1758426923872],{"_100":99,"_107":103},{"_100":99,"_101":-5,"_102":103,"_18":54,"_104":105,"_106":25},{"_13":85,"_32":86,"_43":42,"_87":44,"_88":89,"_90":91,"_92":50,"_93":94,"_95":96,"_97":45,"_98":99},"ctx",{"_78":-5,"_129":299,"_300":301,"_302":303,"_304":25,"_305":25,"_306":25,"_307":58,"_308":-5,"_309":-7,"_310":-7,"_311":62,"_312":25,"_313":25,"_314":-5,"_315":25,"_316":25,"_317":25,"_318":-5},"ENV",{"_270":271,"_272":273,"_274":86,"_275":276,"_277":278,"_279":280,"_281":282,"_283":284,"_285":286,"_287":288,"_289":290,"_291":292,"_293":294,"_295":296,"_297":298},"REACT_APP_SENTRY_DSN","https://586020d86f05489db63a554690acf1e9@o1398359.ingest.sentry.io/6724499","RENDER_GIT_COMMIT","5015b8df46402d8bba4f485ecc37aec202b0e06b","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"]
