User enters text in the textarea\n2. Form submits via JavaScript to `/api/echo` endpoint\n3. Backend receives the text and echoes it back with metadata\n4. Frontend displays the server response next to the form\n\n## API Endpoints\n\n- `GET /` - Serves the main HTML page\n- `POST /api/echo` - Accepts JSON with `text` field, returns echoed response\n\n## Usage\n\nThe application is accessible via the HTTP trigger on the backend. Simply visit the URL and use the form to submit text and see it echoed back.","deleted",false,"children",[],[57],"8c578c1e-8a54-11f0-9870-0224a6c84d84",3,["D",1757075618482],"directory",[76],[52],{"_33":34,"_13":39,"_37":38,"_44":45,"_35":36,"_48":49,"_60":61,"_46":77,"_17":43,"_42":24,"_40":41,"_65":66,"_50":-5,"_67":78,"_18":79},["D",1757251879575],[],[52,39],"8302fd42-8a54-11f0-a6b1-0224a6c84d84","backend","279b3d99-52b4-489b-a2c7-2a4e23573bfd",2,["D",1757075602827],[87],[81],{"_33":88,"_13":89,"_37":90,"_44":82,"_35":36,"_48":91,"_60":61,"_46":92,"_17":93,"_42":94,"_40":95,"_65":66,"_50":-5,"_67":96,"_18":97},"0eeedd5e-8bf3-11f0-8e5a-0224a6c84d84","index.ts","8302f63a-8a54-11f0-a6b1-0224a6c84d84",48,["D",1757253649220],38,"http","import { Hono } from \"https://esm.sh/hono@3.11.7\";\nimport { readFile } from \"https://esm.town/v/std/utils@85-main/index.ts\";\nimport epub from \"jsr:@izg/epub\";\nimport jEpub from \"npm:jepub\";\n// import { SanitizeState } from \"npm:marked-sanitizer-github\";\nimport { JSDOM } from \"npm:jsdom\";\nimport DOMPurify from \"npm:dompurify\";\n\nconst app = new Hono();\n\n// Unwrap Hono errors to see original error details\napp.onError((err) => Promise.reject(err));\n\n// Serve the main HTML page\napp.get(\"/\", async (c) => {\n const html = await readFile(\"/frontend/index.html\", import.meta.url);\n return c.html(html);\n});\n\n// API endpoint to echo back the submitted text\napp.post(\"/api/echo\", async (c) => {\n const body = await c.req.json();\n const { text } = body;\n\n const { marked } = await import(\"https://esm.sh/marked@9.1.6\");\n const { markedXhtml } = await import(\"https://esm.sh/marked-xhtml\");\n\n // Configure marked for EPUB-safe output\n marked.setOptions({\n breaks: true, // Convert line breaks to
