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",[185],"4f5069fc-a2f1-11f0-be41-0224a6c84d84",["D",1759781774911],[27],"pulls","branches","forks","envVars",{"_201":59,"_203":59},"connections",{"_201":59,"_202":59},"count","unfilledCount","emptyCount",{"_40":191,"_31":27,"_29":30,"_150":-5,"_38":39,"_37":14,"_152":55,"_35":230,"_13":59,"_32":20,"_33":34,"_23":24,"_156":-5,"_212":231,"_26":232},{"_40":184,"_31":185,"_29":186,"_150":-5,"_38":39,"_37":187,"_152":55,"_35":227,"_13":59,"_32":20,"_33":189,"_23":24,"_156":-5,"_212":228,"_26":229},{"_40":178,"_31":179,"_29":180,"_150":-5,"_38":39,"_37":151,"_152":55,"_35":224,"_13":59,"_32":169,"_33":182,"_23":24,"_156":-5,"_212":225,"_26":226},{"_40":172,"_31":173,"_29":174,"_150":-5,"_38":39,"_37":151,"_152":55,"_35":221,"_13":59,"_32":20,"_33":176,"_23":24,"_156":-5,"_212":222,"_26":223},{"_40":165,"_31":166,"_29":167,"_150":-5,"_38":39,"_37":151,"_152":55,"_35":218,"_13":59,"_32":169,"_33":170,"_23":24,"_156":-5,"_212":219,"_26":220},{"_40":158,"_31":159,"_29":160,"_150":-5,"_38":39,"_37":161,"_152":55,"_35":215,"_13":59,"_32":20,"_33":163,"_23":24,"_156":-5,"_212":216,"_26":217},{"_40":148,"_31":149,"_29":53,"_150":-5,"_38":39,"_37":151,"_152":24,"_35":211,"_13":59,"_32":154,"_33":155,"_23":24,"_156":-5,"_212":213,"_26":214},["D",1759781656784],"children",[],[149],["D",1759781774909],[],[159],["D",1759781656784],[],[166],["D",1759781656784],[],[173],["D",1759781656784],[],[179],["D",1759781774910],[],[185],["D",1759781774911],[],[27],["D",1759781656784],{"_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":270,"_271":272,"_273":274,"_275":24,"_276":24,"_277":24,"_278":55,"_279":-5,"_280":-7,"_281":-7,"_282":59,"_283":24,"_284":24,"_285":-5,"_286":24,"_287":24,"_288":24,"_289":-5},"ENV",{"_241":242,"_243":244,"_245":83,"_246":247,"_248":249,"_250":251,"_252":253,"_254":255,"_256":257,"_258":259,"_260":261,"_262":263,"_264":265,"_266":267,"_268":269},"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"]
