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",[202],"f4c53bfe-aaff-11f0-b516-0224a6c84d84",["D",1760667674835],[27],"pulls","branches","forks","envVars",{"_218":59,"_220":59},"connections",{"_218":59,"_219":59},"count","unfilledCount","emptyCount",{"_40":208,"_31":27,"_29":30,"_149":-5,"_38":39,"_37":14,"_151":55,"_35":255,"_13":59,"_32":20,"_33":34,"_23":24,"_156":-5,"_231":256,"_26":257},{"_40":201,"_31":202,"_29":203,"_149":-5,"_38":39,"_37":204,"_151":24,"_35":252,"_13":59,"_32":20,"_33":206,"_23":24,"_156":-5,"_231":253,"_26":254},{"_40":195,"_31":196,"_29":197,"_149":-5,"_38":39,"_37":161,"_151":24,"_35":249,"_13":59,"_32":20,"_33":199,"_23":24,"_156":-5,"_231":250,"_26":251},{"_40":187,"_31":188,"_29":189,"_149":-5,"_38":39,"_37":190,"_151":24,"_35":246,"_13":192,"_32":20,"_33":193,"_23":24,"_156":-5,"_231":247,"_26":248},{"_40":180,"_31":181,"_29":182,"_149":-5,"_38":39,"_37":183,"_151":24,"_35":243,"_13":59,"_32":20,"_33":185,"_23":24,"_156":-5,"_231":244,"_26":245},{"_40":172,"_31":173,"_29":174,"_149":-5,"_38":39,"_37":175,"_151":24,"_35":240,"_13":161,"_32":177,"_33":178,"_23":24,"_156":-5,"_231":241,"_26":242},{"_40":166,"_31":167,"_29":168,"_149":-5,"_38":39,"_37":161,"_151":55,"_35":237,"_13":59,"_32":163,"_33":170,"_23":24,"_156":-5,"_231":238,"_26":239},{"_40":158,"_31":159,"_29":160,"_149":-5,"_38":39,"_37":161,"_151":55,"_35":234,"_13":59,"_32":163,"_33":164,"_23":24,"_156":-5,"_231":235,"_26":236},{"_40":148,"_31":42,"_29":53,"_149":-5,"_38":39,"_37":150,"_151":24,"_35":230,"_13":153,"_32":154,"_33":155,"_23":24,"_156":-5,"_231":232,"_26":233},["D",1760667674335],"children",[],[42],["D",1758426923872],[],[159],["D",1758426923872],[],[167],["D",1760667674369],[],[173],["D",1760667674385],[],[181],["D",1760667228205],[],[188],["D",1758426923872],[],[196],["D",1760667674396],[],[202],["D",1760667674835],[],[27],["D",1758426923872],{"_97":96,"_104":100},{"_97":96,"_98":-5,"_99":100,"_18":51,"_101":102,"_103":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,"_126":295,"_296":297,"_298":299,"_300":24,"_301":24,"_302":24,"_303":55,"_304":-5,"_305":-7,"_306":-7,"_307":59,"_308":24,"_309":24,"_310":-5,"_311":24,"_312":24,"_313":24,"_314":-5},"ENV",{"_266":267,"_268":269,"_270":83,"_271":272,"_273":274,"_275":276,"_277":278,"_279":280,"_281":282,"_283":284,"_285":286,"_287":288,"_289":290,"_291":292,"_293":294},"REACT_APP_SENTRY_DSN","https://586020d86f05489db63a554690acf1e9@o1398359.ingest.sentry.io/6724499","RENDER_GIT_COMMIT","fdb67791413f4386b4dbf18f354029a617f6160f","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"]
