Downloaded Content

\"\n});\n\nreturn createHTMLDownload(minifyHTML(html), \"my-export.html\");\n```\n\n## File Structure\n\n```\n├── main.tsx # HTTP val with export endpoints\n├── templates/\n│ └── base.html # Base HTML template\n├── utils/\n│ └── html.ts # Template utilities\n├── components/\n│ └── html.ts # Component-based HTML generation\n└── README.md # This file\n```\n\n## API Endpoints\n\n### GET `/`\nMain dashboard showing available export options.\n\n### GET `/export/simple`\nDownloads a simple HTML page with current timestamp.\n\n### GET `/export/react`\nDownloads a React counter application as a standalone HTML file.\n\n### GET `/export/custom`\nShows a form for creating custom HTML exports.\n\n### POST `/export/custom`\nProcesses form data and generates custom HTML download.\n\n**Form Parameters:**\n- `title` - Page title\n- `content` - HTML content\n- `includeStyles` - Whether to include custom CSS\n\n## Template Variables\n\nThe base template supports these variables:\n- `{{title}}` - Page title\n- `{{head}}` - Additional head content\n- `{{content}}` - Main page content \n- `{{scripts}}` - JavaScript content\n\n## Customization\n\n### Adding New Templates\n\n1. Create a new HTML file in `/templates/`\n2. Use `{{variable}}` syntax for dynamic content\n3. Load with `renderTemplate()`\n\n### Custom Components\n\nExtend the `HTML` object in `/components/html.ts`:\n\n```typescript\nexport const HTML = {\n // ... existing components\n \n customCard: (title: string, content: string): HTMLComponent => ({\n tag: \"div\",\n attributes: { class: \"bg-white p-6 rounded-lg shadow\" },\n children: [\n HTML.h3(title, { class: \"text-lg font-semibold mb-2\" }),\n HTML.p(content, { class: \"text-gray-600\" })\n ]\n })\n};\n```\n\n## Best Practices\n\n1. **Use templates** for consistent layouts\n2. **Minify HTML** for production exports\n3. **Pin React versions** when including React\n4. **Validate user input** in custom exports\n5. **Use semantic HTML** for accessibility\n6. **Include meta tags** for proper rendering\n\n## Troubleshooting\n\n- **Template not found**: Ensure template files exist in `/templates/`\n- **React not loading**: Check that versions are pinned to 18.2.0\n- **Styles not applying**: Verify TailwindCSS script is included\n- **Download not working**: Check Content-Disposition headers",[134],"087a1562-3bba-11f0-953e-9e149126039e","utils","4fb1fbdc-ab43-4753-b8fc-588d7e249ad4",3,["D",1748433064060],"directory",[140],"018e8d64-3bba-11f0-97d3-9e149126039e","templates","8b593ea4-ed59-4dae-8465-cd7c7a30313e",2,["D",1748433052449],[147],"245bccda-3bba-11f0-bdfd-9e149126039e","components","89bf895d-709c-4253-8d79-351754e4855a",6,["D",1748433110837],[153],"pulls",1,"forks","envVars",{"_165":53,"_167":53},"connections",{"_165":53,"_166":53},"count","unfilledCount","emptyCount",{"_20":152,"_13":153,"_119":154,"_120":-5,"_121":21,"_122":155,"_123":49,"_22":211,"_29":53,"_126":144,"_128":-5,"_130":38,"_131":-5,"_177":212,"_89":213},{"_20":205,"_13":184,"_119":206,"_120":154,"_121":21,"_122":155,"_123":49,"_22":207,"_29":53,"_126":187,"_128":208,"_130":38,"_131":-5,"_177":209,"_89":210},{"_20":146,"_13":147,"_119":148,"_120":-5,"_121":21,"_122":149,"_123":49,"_22":202,"_29":53,"_126":144,"_128":-5,"_130":38,"_131":-5,"_177":203,"_89":204},{"_20":194,"_13":195,"_119":196,"_120":148,"_121":21,"_122":197,"_123":49,"_22":198,"_29":159,"_126":101,"_128":199,"_130":38,"_131":-5,"_177":200,"_89":201},{"_20":139,"_13":140,"_119":141,"_120":-5,"_121":21,"_122":142,"_123":49,"_22":191,"_29":53,"_126":144,"_128":-5,"_130":38,"_131":-5,"_177":192,"_89":193},{"_20":183,"_13":184,"_119":185,"_120":141,"_121":21,"_122":142,"_123":49,"_22":186,"_29":53,"_126":187,"_128":188,"_130":38,"_131":-5,"_177":189,"_89":190},{"_20":133,"_13":134,"_119":135,"_120":-5,"_121":21,"_122":125,"_123":49,"_22":180,"_29":53,"_126":101,"_128":137,"_130":38,"_131":-5,"_177":181,"_89":182},{"_20":117,"_13":118,"_119":47,"_120":-5,"_121":21,"_122":30,"_123":49,"_22":176,"_29":125,"_126":127,"_128":129,"_130":38,"_131":-5,"_177":178,"_89":179},["D",1748433478904],"children",[],[118],["D",1748433135882],[],[134],"0879f118-3bba-11f0-953e-9e149126039e","html.ts","0879f1cc-3bba-11f0-953e-9e149126039e",["D",1748433064060],"script","import { readFile } from \"https://esm.town/v/std/utils@85-main/index.ts\";\n\ninterface TemplateData {\n title?: string;\n head?: string;\n content: string;\n scripts?: string;\n}\n\n/**\n * Render HTML using a template with variable substitution\n */\nexport async function renderTemplate(templatePath: string, data: TemplateData): Promise {\n let html = await readFile(templatePath, import.meta.url);\n \n // Default values\n const templateData = {\n title: \"My App\",\n head: \"\",\n scripts: \"\",\n ...data\n };\n \n // Replace template variables\n for (const [key, value] of Object.entries(templateData)) {\n const placeholder = `{{${key}}}`;\n html = html.replaceAll(placeholder, value || \"\");\n }\n \n return html;\n}\n\n/**\n * Generate a complete HTML page with common patterns\n */\nexport async function generatePage(options: {\n title: string;\n content: string;\n includeReact?: boolean;\n customCSS?: string;\n customJS?: string;\n}): Promise {\n const { title, content, includeReact = false, customCSS = \"\", customJS = \"\" } = options;\n \n let head = customCSS ? `` : \"\";\n let scripts = customJS ? `` : \"\";\n \n if (includeReact) {\n head += `\n `;\n }\n \n return renderTemplate(\"/templates/base.html\", {\n title,\n head,\n content,\n scripts\n });\n}\n\n/**\n * Create a downloadable HTML file response\n */\nexport function createHTMLDownload(html: string, filename: string = \"export.html\"): Response {\n return new Response(html, {\n headers: {\n \"Content-Type\": \"text/html\",\n \"Content-Disposition\": `attachment; filename=\"${filename}\"`\n }\n });\n}\n\n/**\n * Minify HTML by removing unnecessary whitespace\n */\nexport function minifyHTML(html: string): string {\n return html\n .replace(/\\s+/g, ' ')\n .replace(/>\\s+<')\n .trim();\n}",[],[140,184],["D",1748433064060],[173],[140],"c57fc2f6-3bba-11f0-8229-9e149126039e","base.html","018e55c4-3bba-11f0-97d3-9e149126039e",8,["D",1748433381184],"\n \n \n \n Pixelated 3D Scene with Leva\n \n \n \n \n
