That's the backend HTTP server, which also serves the all the frontend assets.\n\n- The **client-side entrypoint** is [`/frontend/index.html`](/frontend/index.html)\n - which in turn imports [`/frontend/index.tsx`](/frontend/index.tsx)\n - which in turn imports the React app from [`/frontend/components/App.tsx`](/frontend/components/App.tsx).\n\nSo if you wanted to get a sense of how this app comes together, we suggest reading the files in this order: \n\n[`/backend/index.ts`](/backend/index.ts) -> [`/frontend/index.html`](/frontend/index.html) -> [`/frontend/index.tsx`](/frontend/index.tsx) -> [`/frontend/components/App.tsx`](/frontend/components/App.tsx)\n\n## Further resources\n\n- [React Hono Example](https://www.val.town/x/stevekrouse/reactHonoExample) is a bigger example project, with a SQLite database table, queries, client-side CSS, a favicon, and shared code that runs on both client and server.","children",[],[198],"9c96f494-78ab-11f0-a3c3-0224a6c84d84","style.css","0198a621-d1ce-71dd-8708-6b7b2191f68c",["D",1755133890927],"body {\n font-family: -apple-system, Arial, sans-serif;\n color: #333;\n padding: 20px;\n}\n\nbutton {\n background-color: #4a90e2;\n color: white;\n border: none;\n padding: 8px 16px;\n border-radius: 4px;\n cursor: pointer;\n}\n\nbutton:hover {\n background-color: #357ae8;\n}",[],[171,206],"3f99936c-78ad-11f0-81a7-0224a6c84d84","index.tsx","0198a621-d1ce-71dd-8708-673b533a1615",["D",1755134594003],2,"/** @jsxImportSource https://esm.sh/react@18.2.0 */\nimport { createRoot } from \"https://esm.sh/react-dom@18.2.0/client\";\nimport React, { useEffect, useState } from \"https://esm.sh/react@18.2.0\";\nimport {\n AlertCircle,\n CheckCircle,\n Key,\n LogOut,\n Shield,\n User,\n} from \"npm:lucide-react\";\n\nconst PasskeyDemo = () => {\n const [isSignedIn, setIsSignedIn] = useState(false);\n const [user, setUser] = useState(null);\n const [isLoading, setIsLoading] = useState(false);\n const [message, setMessage] = useState(\"\");\n const [messageType, setMessageType] = useState(\"info\");\n const [isSupported, setIsSupported] = useState(false);\n const [lastError, setLastError] = useState(null);\n\n useEffect(() => {\n // Check if WebAuthn is supported\n setIsSupported(window?.PublicKeyCredential !== undefined);\n\n // Check if user is already signed in (simulated)\n const storedUser = JSON.parse(\n localStorage.getItem(\"passkey-user\") || \"null\",\n );\n if (storedUser) {\n setUser(storedUser);\n setIsSignedIn(true);\n }\n }, []);\n\n const showMessage = (text, type = \"info\") => {\n setMessage(text);\n setMessageType(type);\n setTimeout(() => setMessage(\"\"), 5000);\n };\n\n const generateRandomBytes = (length) => {\n const array = new Uint8Array(length);\n crypto.getRandomValues(array);\n return array;\n };\n\n const bufferToBase64 = (buffer) => {\n return btoa(String.fromCharCode(...new Uint8Array(buffer)));\n };\n\n const base64ToBuffer = (base64) => {\n const binaryString = atob(base64);\n const bytes = new Uint8Array(binaryString.length);\n for (let i = 0;

\n How it works:\n

• Uses your device's built-in authentication
• Biometric or PIN verification
• No passwords to remember or store
• Phishing-resistant security

\n\n

\n Troubleshooting:\n

• Make sure you're on HTTPS or localhost
• Enable biometrics/PIN on your device
• Try a different browser if issues persist
• Some corporate networks may block WebAuthn
