Demo](https://jxnblk--122089bc0b3011f09093569c3dd06744.web.val.run/)\n\nRemix this project to start building your own React app\n\n## How it works\n\nThe `http.tsx` file is the main entry point and serves the app.\nIt renders the `App` component on the server and wraps it in an HTML response.\nThis HTML response includes a `` 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')` 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],"c1b007ac-a2ea-11f0-bf13-0224a6c84d84",".vtignore","c1b00860-a2ea-11f0-bf13-0224a6c84d84",11,["D",1759778960386],".git\n.vscode\n.cursorrules\n.DS_Store\nnode_modules\nvendor",[194],"pulls","branches","forks","envVars",{"_207":61,"_209":61},"connections",{"_207":61,"_208":61},"count","unfilledCount","emptyCount",{"_43":193,"_32":194,"_30":195,"_151":-5,"_41":42,"_40":196,"_152":57,"_38":236,"_13":61,"_33":20,"_35":198,"_24":25,"_155":-5,"_218":237,"_27":238},{"_43":186,"_32":187,"_30":188,"_151":-5,"_41":42,"_40":189,"_152":57,"_38":233,"_13":61,"_33":20,"_35":191,"_24":25,"_155":-5,"_218":234,"_27":235},{"_43":179,"_32":180,"_30":181,"_151":-5,"_41":42,"_40":182,"_152":25,"_38":230,"_13":61,"_33":169,"_35":184,"_24":25,"_155":-5,"_218":231,"_27":232},{"_43":172,"_32":173,"_30":174,"_151":-5,"_41":42,"_40":175,"_152":25,"_38":227,"_13":61,"_33":20,"_35":177,"_24":25,"_155":-5,"_218":228,"_27":229},{"_43":164,"_32":165,"_30":166,"_151":-5,"_41":42,"_40":167,"_152":25,"_38":224,"_13":61,"_33":169,"_35":170,"_24":25,"_155":-5,"_218":225,"_27":226},{"_43":157,"_32":158,"_30":159,"_151":-5,"_41":42,"_40":160,"_152":57,"_38":221,"_13":61,"_33":20,"_35":162,"_24":25,"_155":-5,"_218":222,"_27":223},{"_43":150,"_32":28,"_30":31,"_151":-5,"_41":42,"_40":14,"_152":25,"_38":217,"_13":154,"_33":34,"_35":37,"_24":25,"_155":-5,"_218":219,"_27":220},["D",1759779155925],"children",[],[28],["D",1759778960227],[],[158],["D",1759778960334],[],[165],["D",1759778960299],[],[173],["D",1759778960229],[],[180],["D",1759778960291],[],[187],["D",1759778960386],[],[194],["D",1759778939154],{"_99":98,"_107":103},{"_99":98,"_100":101,"_102":103,"_18":54,"_104":105,"_106":25},{"_13":84,"_32":85,"_43":42,"_86":44,"_87":88,"_89":90,"_91":50,"_92":93,"_94":95,"_96":45,"_97":98},"ctx",{"_77":-5,"_129":276,"_277":278,"_279":280,"_281":25,"_282":25,"_283":25,"_284":57,"_285":-5,"_286":-7,"_287":-7,"_288":61,"_289":25,"_290":25,"_291":-5,"_292":25,"_293":25,"_294":25,"_295":-5},"ENV",{"_247":248,"_249":250,"_251":85,"_252":253,"_254":255,"_256":257,"_258":259,"_260":261,"_262":263,"_264":265,"_266":267,"_268":269,"_270":271,"_272":273,"_274":275},"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"]
