\n\n```\n\n#### Benefits:\n- **SEO friendly**: Search engines can index the fallback content\n- **Accessibility**: Users with disabled JavaScript still get useful content\n- **Performance**: Fast initial load with progressive enhancement\n\n### 5. TypeScript Configuration for Val Town\n\n#### Deno Configuration (`deno.json`)\n```json\n{\n \"compilerOptions\": {\n \"noImplicitAny\": false,\n \"strict\": true,\n \"lib\": [\"dom\", \"dom.iterable\", \"deno.ns\", \"deno.unstable\"]\n },\n \"lint\": {\n \"rules\": {\n \"exclude\": [\"no-explicit-any\", \"no-import-prefix\"]\n }\n }\n}\n```\n\n#### Key Settings:\n- **Deno-specific libs**: Include `deno.ns` and `deno.unstable`\n- **Import prefix rules**: Exclude `no-import-prefix` to allow ESM.sh imports\n- **Strict mode**: Enable but allow `any` types where needed\n\n### 6. TailwindCSS Integration\n\n#### CDN-based Setup\n```html\n\n```\n\n#### Utility Classes in TSX\n```tsx\n

\n {/* Content */}\n

\n```\n\n### 7. File Organization Best Practices\n\n#### Recommended Structure\n```\n├── index.html # No-JS fallback + React container\n├── index.tsx # React app entry point\n├── App.tsx # Main component\n├── deno.json # Deno configuration\n├── CRUSH.md # Agent development guidelines\n└── .gitignore # Exclude .vt/, .crush/, etc.\n```\n\n#### File Naming Conventions\n- **Entry points**: `index.tsx` for React apps\n- **Components**: PascalCase (App.tsx, Header.tsx)\n- **HTML**: `index.html` as the primary file\n\n### 8. Error Handling & Debugging\n\n#### Platform Limitations\n- No `console.log` in production (use proper logging)\n- Limited debugging tools compared to traditional servers\n- Network requests must be HTTPS\n- No server-side file system access\n\n#### Best Practices\n- Use try/catch for async operations\n- Provide user-friendly error messages\n- Test with `vt status` before pushing\n- Use `vt tail` to monitor logs in production\n\n### 9. Performance Considerations\n\n#### Optimization Techniques\n- **Code splitting**: Keep components focused and small\n- **Lazy loading**: Import components only when needed\n- **Bundle size**: Monitor via browser dev tools\n- **Caching**: Leverage browser caching for assets\n\n#### Val Town Specific\n- **Cold starts**: First request may be slower\n- **Memory limits**: Be mindful of resource usage\n- **Concurrent requests**: Platform handles scaling automatically\n\n### 10. Development Workflow\n\n#### Local Development\n```bash\n# Check TypeScript compilation\ndeno check\n\n# Run linter\ndeno lint *.tsx\n\n# Test locally (serve static files)\npython -m http.server 8000\n```\n\n#### Deployment Cycle\n1. Make changes locally\n2. Test with `deno check` and `deno lint`\n3. Check `vt status` for pending changes\n4. `vt push` to deploy\n5. `vt browse` to verify deployment\n\n### 11. Security Considerations\n\n#### Best Practices\n- **No secrets in code**: Use environment variables\n- **Input validation**: Sanitize all user inputs\n- **HTTPS only**: All external requests must use HTTPS\n- **CORS handling**: Configure appropriate CORS headers\n\n#### Val Town Specific\n- **Environment variables**: Access via `Deno.env.get()`\n- **No file system access**: Cannot read/write server files\n- **Sandbox environment**: Isolated execution context\n\n### 12. Integration Patterns\n\n#### API Endpoints\n```typescript\n// HTTP endpoint val\nexport default async function(req: Request): Promise {\n // Handle request\n return new Response(\"Hello World\");\n}\n```\n\n#### Cron Jobs\n```typescript\n// Cron trigger val\nexport default async function(): Promise {\n // Scheduled task\n}\n```\n\n### 13. Tooling & CLI\n\n#### VT Commands Mastered\n- `vt status` - Check deployment status\n- `vt push` - Deploy changes\n- `vt pull` - Sync remote changes\n- `vt browse` - Open in browser\n- `vt create` - Create new vals\n- `vt clone` - Clone existing vals\n\n### 14. Common Pitfalls & Solutions\n\n#### File Upload Issues\n- **Binary files**: Cannot upload binary files > certain size\n- **Database files**: SQLite files cannot be deployed\n- **Empty files**: Files must have content\n\n#### Import Issues\n- **Version pinning**: Always pin dependency versions\n- **ESM.sh URLs**: Use full URLs for imports\n- **Lint conflicts**: Configure linter to allow Val Town patterns\n\n#### React Specific\n- **JSX transform**: Must use `@jsxImportSource`\n- **Component mounting**: Use `createRoot` for React 18\n- **Styling conflicts**: TailwindCSS works but may need custom config\n\n## Key Takeaways\n\n1. **Val Town is perfect for**: Small web apps, APIs, scheduled tasks, and rapid prototyping\n2. **React works great**: With proper JSX configuration and pinned versions\n3. **Progressive enhancement**: Essential for accessibility and SEO\n4. **Deployment is simple**: Just `vt push` after local testing\n5. **Platform limitations**: Must design around serverless constraints\n6. **TypeScript first**: Strong typing is encouraged and well-supported\n7. **ESM.sh ecosystem**: Rich ecosystem of packages available via ESM.sh\n\n## Future Learning Areas\n\n- **Advanced patterns**: Custom hooks, context providers, routing\n- **Database integration**: Val Town's built-in SQLite support\n- **Real-time features**: WebSockets and server-sent events\n- **Multi-val architectures**: Coordinating between multiple vals\n- **Performance optimization**: Bundle analysis and code splitting\n- **Testing strategies**: Unit and integration testing approaches\n\n## Resources\n\n- [Val Town Docs](https://docs.val.town)\n- [ESM.sh](https://esm.sh) - Package registry\n- [TailwindCSS](https://tailwindcss.com) - Utility-first CSS\n- [React 18 Docs](https://react.dev) - Latest React features\n\n---\n\n*Documented on: 2025-01-19*\n*Platform: Val Town*\n*Project: mcp2cli React TSX conversion*\nskills/val-town-development.md",[],[151,170],[151],{"_102":180,"_95":181,"_152":182,"_154":-5,"_155":137,"_156":183,"_158":159,"_104":184,"_99":32,"_161":174,"_163":185,"_164":22,"_165":-5,"_166":186,"_98":187},"f94dbbcc-ad3b-11f0-86e1-0224a6c84d84",".gitignore","f94dbc80-ad3b-11f0-86e1-0224a6c84d84",8,["D",1760913354569],".vt/\n.crush/\n*.log\n.DS_Store\nnode_modules/",[],[181],{"_102":189,"_95":190,"_152":191,"_154":-5,"_155":137,"_156":192,"_158":159,"_104":193,"_99":32,"_161":174,"_163":194,"_164":22,"_165":-5,"_166":195,"_98":196},"f940e5e6-ad3b-11f0-86e1-0224a6c84d84",".vtignore","f940e686-ad3b-11f0-86e1-0224a6c84d84",6,["D",1760913354485],".git\n.vscode\n.cursorrules\n.DS_Store\nnode_modules\nvendor",[],[190],{"_102":198,"_95":199,"_152":200,"_154":-5,"_155":137,"_156":201,"_158":159,"_104":202,"_99":32,"_161":174,"_163":203,"_164":22,"_165":-5,"_166":204,"_98":205},"f947ab1a-ad3b-11f0-aba1-0224a6c84d84","AGENTS.md","f947abe2-ad3b-11f0-aba1-0224a6c84d84",7,["D",1760913354490],"You are an advanced assistant specialized in generating Val Town code.\n\n## Core Guidelines\n\n- Ask clarifying questions when requirements are ambiguous\n- Provide complete, functional solutions rather than skeleton implementations\n- Test your logic against edge cases before presenting the final solution\n- Ensure all code follows Val Town's specific platform requirements\n- If a section of code that you're working on is getting too complex, consider refactoring it into subcomponents\n\n## Code Standards\n\n- Generate code in TypeScript or TSX\n- Add appropriate TypeScript types and interfaces for all data structures\n- Prefer official SDKs or libraries than writing API calls directly\n- Ask the user to supply API or library documentation if you are at all unsure about it\n- **Never bake in secrets into the code** - always use environment variables\n- Include comments explaining complex logic (avoid commenting obvious operations)\n- Follow modern ES6+ conventions and functional programming practices if possible\n\n## Types of triggers\n\n### 1. HTTP Trigger\n\n- Create web APIs and endpoints\n- Handle HTTP requests and responses\n- Example structure:\n\n```ts\nexport default async function (req: Request) {\n return new Response(\"Hello World\");\n}\n```\n\nFiles that are HTTP triggers have http in their name like `foobar.http.tsx`\n\n### 2. Cron Triggers\n\n- Run on a schedule\n- Use cron expressions for timing\n- Example structure:\n\n```ts\nexport default async function () {\n // Scheduled task code\n}\n```\n\nFiles that are Cron triggers have cron in their name like `foobar.cron.tsx`\n\n### 3. Email Triggers\n\n- Process incoming emails\n- Handle email-based workflows\n- Example structure:\n\n```ts\nexport default async function (email: Email) {\n // Process email\n}\n```\n\nFiles that are Email triggers have email in their name like `foobar.email.tsx`\n\n\n## Val Town Standard Libraries\n\nVal Town provides several hosted services and utility functions.\n\n### Blob Storage\n\n```ts\nimport { blob } from \"https://esm.town/v/std/blob\";\nawait blob.setJSON(\"myKey\", { hello: \"world\" });\nlet blobDemo = await blob.getJSON(\"myKey\");\nlet appKeys = await blob.list(\"app_\");\nawait blob.delete(\"myKey\");\n```\n\n### SQLite\n\n```ts\nimport { sqlite } from \"https://esm.town/v/stevekrouse/sqlite\";\nconst TABLE_NAME = 'todo_app_users_2';\n// Create table - do this before usage and change table name when modifying schema\nawait sqlite.execute(`CREATE TABLE IF NOT EXISTS ${TABLE_NAME} (\n id INTEGER PRIMARY KEY AUTOINCREMENT,\n name TEXT NOT NULL\n)`);\n// Query data\nconst result = await sqlite.execute(`SELECT * FROM ${TABLE_NAME} WHERE id = ?`, [1]);\n```\n\nNote: When changing a SQLite table's schema, change the table's name (e.g., add _2 or _3) to create a fresh table.\n\n### OpenAI\n\n```ts\nimport { OpenAI } from \"https://esm.town/v/std/openai\";\nconst openai = new OpenAI();\nconst completion = await openai.chat.completions.create({\n messages: [\n { role: \"user\", content: \"Say hello in a creative way\" },\n ],\n model: \"gpt-4o-mini\",\n max_tokens: 30,\n});\n```\n\n### Email\n\n```ts\nimport { email } from \"https://esm.town/v/std/email\";\n// By default emails the owner of the val\nawait email({ \n subject: \"Hi\", \n text: \"Hi\", \n html: \"

Hi

\"\n});\n```\n\n## Val Town Utility Functions\n\nVal Town provides several utility functions to help with common project tasks.\n\n### Importing Utilities\n\nAlways import utilities with version pins to avoid breaking changes:\n\n```ts\nimport { parseProject, readFile, serveFile } from \"https://esm.town/v/std/utils@85-main/index.ts\";\n```\n\n### Available Utilities\n\n\n#### **serveFile** - Serve project files with proper content types\n\nFor example, in Hono:\n\n```ts\n// serve all files in frontend/ and shared/\napp.get(\"/frontend/*\", c => serveFile(c.req.path, import.meta.url));\napp.get(\"/shared/*\", c => serveFile(c.req.path, import.meta.url));\n```\n\n#### **readFile** - Read files from within the project:\n\n```ts\n// Read a file from the project\nconst fileContent = await readFile(\"/frontend/index.html\", import.meta.url);\n```\n\n#### **listFiles** - List all files in the project\n\n```ts\nconst files = await listFiles(import.meta.url);\n```\n\n#### **parseProject** - Extract information about the current project from import.meta.url\n\nThis is useful for including info for linking back to a val, ie in \"view source\" urls:\n\n```ts\nconst projectVal = parseProject(import.meta.url);\nconsole.log(projectVal.username); // Owner of the project\nconsole.log(projectVal.name); // Project name\nconsole.log(projectVal.version); // Version number\nconsole.log(projectVal.branch); // Branch name\nconsole.log(projectVal.links.self.project); // URL to the project page\n```\n\nHowever, it's *extremely importing* to note that `parseProject` and other Standard Library utilities ONLY RUN ON THE SERVER.\nIf you need access to this data on the client, run it in the server and pass it to the client by splicing it into the HTML page\nor by making an API request for it.\n\n## Val Town Platform Specifics\n\n- **Redirects:** Use `return new Response(null, { status: 302, headers: { Location: \"/place/to/redirect\" }})` instead of `Response.redirect` which is broken\n- **Images:** Avoid external images or base64 images. Use emojis, unicode symbols, or icon fonts/libraries instead\n- **AI Image:** To inline generate an AI image use: `

`\n- **Storage:** DO NOT use the Deno KV module for storage\n- **Browser APIs:** DO NOT use the `alert()`, `prompt()`, or `confirm()` methods\n- **Weather Data:** Use open-meteo for weather data (doesn't require API keys) unless otherwise specified\n- **View Source:** Add a view source link by importing & using `import.meta.url.replace(\"ems.sh\", \"val.town)\"` (or passing this data to the client) and include `target=\"_top\"` attribute\n- **Error Debugging:** Add `` 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",[],[199],{"_102":207,"_95":208,"_152":209,"_154":-5,"_155":137,"_156":210,"_158":159,"_104":211,"_99":212,"_161":213,"_163":214,"_164":22,"_165":-5,"_166":215,"_98":216},"0339a59e-ad3f-11f0-a343-0224a6c84d84","App.tsx","f983f3ea-ad3b-11f0-aeaa-0224a6c84d84",25,["D",1760914659694],2,"script","/** @jsxImportSource https://esm.sh/react@18.2.0 **/\nimport React, { useState } from \"https://esm.sh/react@18.2.0\";\n\ninterface ServerConfig {\n name: string;\n transport: string;\n command?: string;\n args?: string[];\n url?: string;\n}\n\nexport default function App() {\n const [serverName, setServerName] = useState(\"\");\n const [transport, setTransport] = useState(\"stdio\");\n const [command, setCommand] = useState(\"\");\n const [args, setArgs] = useState(\"\");\n const [url, setUrl] = useState(\"\");\n const [result, setResult] = useState(null);\n const [isLoading, setIsLoading] = useState(false);\n\n const handleSubmit = async (e: React.FormEvent) => {\n e.preventDefault();\n\n if (!serverName.trim()) {\n alert(\"Server name is required.\");\n return;\n }\n\n const config: ServerConfig = {\n name: serverName,\n transport: transport,\n };\n\n if (transport === \"stdio\") {\n if (!command.trim()) {\n alert(\"Command is required for stdio transport.\");\n return;\n }\n config.command = command;\n const argsArray = args.split(\",\").map(arg => arg.trim()).filter(arg => arg);\n if (argsArray.length > 0) {\n config.args = argsArray;\n }\n } else {\n if (!url.trim()) {\n alert(\"URL is required for http/sse transport.\");\n return;\n }\n config.url = url;\n }\n\n setIsLoading(true);\n try {\n const response = await fetch(\"/api\", {\n method: \"POST\",\n headers: {\n \"Content-Type\": \"application/json\",\n },\n body: JSON.stringify(config),\n });\n\n if (!response.ok) {\n throw new Error(`HTTP error! status: ${response.status}`);\n }\n\n const responseData = await response.json();\n setResult(JSON.stringify(responseData, null, 2));\n } catch (error) {\n setResult(error instanceof Error ? error.message : \"An unknown error occurred.\");\n } finally {\n setIsLoading(false);\n }\n };\n\n return (\n

For manual testing:\n- Open index.html in browser\n- Test form submission functionality\n- Verify transport field toggling\n- Test React state management\n\n## Code Style Guidelines\n\n### Language & Framework\n- **Language**: TypeScript with TSX (React components)\n- **Runtime**: Deno (Val Town environment)\n- **Framework**: React 18.2.0 with pinned versions\n- **Styling**: TailwindCSS via CDN\n- **Imports**: Use `https://esm.sh` for external dependencies\n\n### React Configuration\n- **JSX Transform**: `/** @jsxImportSource https://esm.sh/react@18.2.0 */`\n- **React Version**: All dependencies pinned to 18.2.0\n- **State Management**: React useState hooks\n- **Styling**: TailwindCSS classes (no CSS modules)\n\n### TypeScript Configuration\n- `strict: true` - All strict checks enabled\n- `noImplicitAny: false` - Explicit any types allowed but discouraged\n- Include Val Town types: `\"https://www.val.town/types/valtown.d.ts\"`\n- DOM and Deno libraries available\n\n### Naming Conventions\n- **Files**: camelCase for TSX files (App.tsx, index.tsx)\n- **Components**: PascalCase (App, ServerConfig)\n- **Variables**: camelCase\n- **Functions**: camelCase, descriptive names\n- **Types/Interfaces**: PascalCase\n- **Constants**: UPPER_SNAKE_CASE\n- **Props**: camelCase\n\n### Code Structure\n- **Components**: Functional components with hooks\n- **State**: useState for local component state\n- **Events**: React event handlers (e.g., onChange, onSubmit)\n- **Props**: TypeScript interfaces for component props\n- **Styling**: TailwindCSS utility classes\n\n### Best Practices\n- Use `const` by default, `let` only when reassignment needed\n- Prefer arrow functions for callbacks\n- Add TypeScript types for all data structures and props\n- Handle errors gracefully with user-friendly messages\n- Avoid `any` types - use proper interfaces\n- Keep components small and focused\n- Use modern ES6+ features and React patterns\n\n### Security\n- Never bake secrets into code\n- Use environment variables: `Deno.env.get('VAR_NAME')`\n- Validate and sanitize user inputs\n- Use HTTPS for external requests\n\n### Val Town Specifics\n- No Node.js APIs available\n- Use Val Town standard libraries when needed\n- Follow Val Town platform limitations and gotchas\n- HTML file serves as no-JS fallback\n\n## Project Structure\n```\n├── index.html # No-JS fallback with React app container\n├── index.tsx # React app entry point\n├── App.tsx # Main React component\n├── deno.json # Deno configuration\n├── AGENTS.md # Val Town development guidelines\n├── CRUSH.md # This file\n├── skills/ # Development skills documentation\n│ └── val-town-development.md\n└── .gitignore # Git ignore rules\n```\nCRUSH.md",[],[219],{"_102":228,"_95":229,"_152":230,"_154":-5,"_155":137,"_156":231,"_158":159,"_104":232,"_99":32,"_161":174,"_163":233,"_164":22,"_165":-5,"_166":234,"_98":235},"f93085e8-ad3b-11f0-a446-0224a6c84d84","deno.json","f93086b0-ad3b-11f0-a446-0224a6c84d84",5,["D",1760913354375],"{\n \"$schema\": \"https://raw.githubusercontent.com/denoland/deno/98f62cee78e85bfc47c62ed703777c6bc8794f1c/cli/schemas/config-file.v1.json\",\n \"lock\": false,\n \"compilerOptions\": {\n \"noImplicitAny\": false,\n \"strict\": true,\n \"lib\": [\n \"dom\",\n \"dom.iterable\",\n \"dom.asynciterable\",\n \"deno.ns\",\n \"deno.unstable\"\n ]\n },\n \"lint\": {\n \"rules\": {\n \"exclude\": [\"no-explicit-any\", \"no-import-prefix\"]\n }\n },\n \"node_modules_dir\": false,\n \"experimental\": {\n \"unstable-node-globals\": true,\n \"unstable-temporal\": true,\n \"unstable-worker-options\": true,\n \"unstable-sloppy-imports\": true\n }\n}",[],[229],{"_102":237,"_95":238,"_152":239,"_154":-5,"_155":137,"_156":240,"_158":159,"_104":241,"_99":223,"_161":174,"_163":242,"_164":22,"_165":-5,"_166":243,"_98":244},"f97ec44c-ad3b-11f0-a44f-0224a6c84d84","index.html","18ae0820-ad35-11f0-90da-0224a6c84d84",12,["D",1760913354831],"\n\n\n \n \n mcp2cli - MCP Configuration Generator\n \n\n\n
