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",[187],"6b6a26b8-a2e8-11f0-8bfa-0224a6c84d84",".vtignore","6b6a2780-a2e8-11f0-8bfa-0224a6c84d84",3,["D",1759777956649],".git\n.vscode\n.cursorrules\n.DS_Store\nnode_modules\nvendor",[194],"6f13aeec-a2e8-11f0-bd1e-0224a6c84d84",["D",1759777962769],[27],"pulls","branches","forks","envVars",{"_210":59,"_212":59},"connections",{"_210":59,"_211":59},"count","unfilledCount","emptyCount",{"_40":200,"_31":27,"_29":30,"_152":-5,"_38":39,"_37":14,"_154":55,"_35":243,"_13":59,"_32":33,"_34":-5,"_23":24,"_158":-5,"_222":244,"_26":245},{"_40":193,"_31":194,"_29":195,"_152":-5,"_38":39,"_37":196,"_154":55,"_35":240,"_13":59,"_32":20,"_34":198,"_23":24,"_158":-5,"_222":241,"_26":242},{"_40":186,"_31":187,"_29":188,"_152":-5,"_38":39,"_37":189,"_154":55,"_35":237,"_13":59,"_32":20,"_34":191,"_23":24,"_158":-5,"_222":238,"_26":239},{"_40":180,"_31":181,"_29":182,"_152":-5,"_38":39,"_37":153,"_154":24,"_35":234,"_13":59,"_32":20,"_34":184,"_23":24,"_158":-5,"_222":235,"_26":236},{"_40":174,"_31":175,"_29":176,"_152":-5,"_38":39,"_37":153,"_154":55,"_35":231,"_13":59,"_32":164,"_34":178,"_23":24,"_158":-5,"_222":232,"_26":233},{"_40":167,"_31":168,"_29":169,"_152":-5,"_38":39,"_37":170,"_154":55,"_35":228,"_13":59,"_32":20,"_34":172,"_23":24,"_158":-5,"_222":229,"_26":230},{"_40":160,"_31":161,"_29":162,"_152":-5,"_38":39,"_37":153,"_154":55,"_35":225,"_13":59,"_32":164,"_34":165,"_23":24,"_158":-5,"_222":226,"_26":227},{"_40":150,"_31":151,"_29":53,"_152":-5,"_38":39,"_37":153,"_154":24,"_35":221,"_13":59,"_32":156,"_34":157,"_23":24,"_158":-5,"_222":223,"_26":224},["D",1759777861761],"children",[],[151],["D",1759777861761],[],[161],["D",1759777956636],[],[168],["D",1759777861761],[],[175],["D",1759777861761],[],[181],["D",1759777956637],[],[187],["D",1759777956649],[],[194],["D",1759777962769],[],[27],["D",1759777861761],{"_97":96,"_105":101},{"_97":96,"_98":99,"_100":101,"_18":51,"_102":103,"_104":24},{"_13":82,"_31":83,"_40":39,"_84":41,"_85":86,"_87":88,"_89":47,"_90":91,"_92":93,"_94":42,"_95":96},"ctx",{"_75":-5,"_127":283,"_284":285,"_286":287,"_288":24,"_289":24,"_290":24,"_291":55,"_292":-5,"_293":-7,"_294":-7,"_295":59,"_296":24,"_297":24,"_298":-5,"_299":24,"_300":24,"_301":24,"_302":-5},"ENV",{"_254":255,"_256":257,"_258":83,"_259":260,"_261":262,"_263":264,"_265":266,"_267":268,"_269":270,"_271":272,"_273":274,"_275":276,"_277":278,"_279":280,"_281":282},"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"]
