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 - Properly handle CORS if needed for external access",[],[156,191],[156],{"_103":200,"_95":201,"_157":202,"_159":-5,"_160":140,"_161":162,"_163":117,"_105":203,"_100":32,"_165":166,"_167":-5,"_168":22,"_169":-5,"_170":204,"_99":320},"ab982940-09b1-11f0-b6bf-569c3dd06744","frontend","697aa19b-8df8-43e9-8e83-533baf1225d0",["D",1742931914106],[205,296,311],{"_103":206,"_95":207,"_157":208,"_159":202,"_160":140,"_161":162,"_163":117,"_105":209,"_100":32,"_165":166,"_167":-5,"_168":22,"_169":-5,"_170":210,"_99":295},"ab982116-09b1-11f0-b6bf-569c3dd06744","components","74ace39a-a5cd-4a8f-957f-bebea661ceb4",["D",1742931914106],[211,221,229,239,247,255,263,271,279,287],{"_103":212,"_95":213,"_157":214,"_159":208,"_160":140,"_161":215,"_163":117,"_105":216,"_100":217,"_165":177,"_167":218,"_168":22,"_169":-5,"_170":219,"_99":220},"7a28dade-09b2-11f0-9237-569c3dd06744","App.tsx","1f79fa0d-9050-42c2-9616-c4757689ead0",8,["D",1742932260666],4,"/** @jsxImportSource https://esm.sh/react@18.2.0?dev */\nimport { useLocalStorage } from \"https://esm.sh/react-use?dev&deps=react@18.2.0&react-dom@18.2.0\";\nimport React, { useState } from \"https://esm.sh/react@18.2.0?dev\";\nimport { Chat } from \"./Chat.tsx\";\nimport { Login } from \"./Login.tsx\";\nimport { SvgEditor } from \"./SvgEditor.tsx\";\n\nexport function App() {\n const [bearerToken, setBearerToken] = useLocalStorage(\"bearer\", \"\");\n const [anthropicApiKey, setAnthropicApiKey] = useLocalStorage(\"anthropic_api_key\", \"\");\n const [currentSvg, setCurrentSvg] = useState(\"\");\n \n // Create a default project for SVG editing\n const defaultProject = {\n name: \"SVG Editor\",\n id: \"svg-editor\",\n username: \"user\"\n };\n\n function handleLogout() {\n setBearerToken(\"\");\n // Keep the anthropic API key in case the user wants to reuse it\n }\n\n // Handle SVG change callback\n const handleSvgChange = (svgString: string) => {\n setCurrentSvg(svgString);\n };\n\n return (\n
