Literally zero set up required.\n\nNote: Sending emails to users besides yourself requires [Val Town Pro](https://www.val.town/pricing).\n\n## Features\n\n- Magic link authentication\n- Server-side rendering with client-side hydration\n- User profile management (username editing)\n- Session management with secure cookies\n- Responsive UI with Tailwind CSS\n\n## Authentication Flow\n\n1. User enters their email address on the login page\n2. A magic link is sent to the user's email\n3. User clicks the magic link in their email\n4. The server validates the token, creates a session, and sets a secure cookie\n5. User is redirected to the authenticated home page\n\n## Technical Implementation\n\n- **Database**:[Val Town SQLite](https://docs.val.town/std/sqlite/) for storing users, sessions, and magic link tokens\n- **Frontend**: React with Tailwind CSS\n- **Backend**: Hono.js for API routes and middleware\n- **Authentication**: Built by following the [Lucia guide](https://lucia-next.pages.dev/)\n\n## API Endpoints\n\nProvided by the Auth Middleware in `backend/auth.ts`:\n\n- `POST /auth/magic-link` - Request a magic link\n- `GET /auth/magic-link/:token` - Validate a magic link token\n- `POST /auth/logout` - Log out the current user\n\nIn the app's API, in `backend/index.ts`:\n\n- `POST /api/user/username` - Update the user's username\n\n## Notes\n\n- Email sending requires Val Town Pro subscription for sending to addresses other than your own\n- Magic links expire after 15 minutes\n- Session tokens are automatically rotated when 50% of their lifetime remains (15 days)\n- Sessions expire after 30 days\n\n## Todos\n\n- When I tried to make the magic link token single-use, it caused issues. I think the best practice there is something a bit more complicated, ie a GET request to an HTML page that makes a POST request.\n- When I tried to make the SameSite=Strict, the cookie stopped working. It's currently Lax, which I think is OK, but it'd be nice to know Strict isn't working.","children",[],[226],["D",1748164698080],[],[18,92],["D",1748164698080],[],[18,75],"31e8b46c-3949-11f0-817e-9e149126039e","UserProfile.tsx","136566b7-03ef-400d-88dc-e776d9bbb1dc",["D",1748164698080],"/** @jsxImportSource https://esm.sh/react@18.2.0 */\nimport { useState } from \"https://esm.sh/react@18.2.0\";\n\ninterface User {\n id: number;\n email?: string;\n username?: string;\n}\n\ninterface UserProfileProps {\n user: User;\n onUpdate: (user: User) => void;\n}\n\nexport function UserProfile({ user, onUpdate }: UserProfileProps) {\n const [username, setUsername] = useState(user.username || \"\");\n const [isEditing, setIsEditing] = useState(false);\n const [isSubmitting, setIsSubmitting] = useState(false);\n const [error, setError] = useState(null);\n\n const handleSubmit = async (e: React.FormEvent) => {\n e.preventDefault();\n\n if (!username.trim()) {\n setError(\"Username cannot be empty\");\n return;\n }\n\n // Client-side validation to match server-side rules\n if (username.length < 3 || username.length > 50) {\n setError(\"Username must be between 3 and 50 characters\");\n return;\n }\n\n // Ensure username is only letters and numbers\n if (!/^[a-zA-Z0-9]+$/.test(username)) {\n setError(\"Username can only contain letters and numbers\");\n return;\n }\n\n setIsSubmitting(true);\n setError(null);\n\n try {\n const response = await fetch(\"/api/user/username\", {\n method: \"POST\",\n headers: {\n \"Content-Type\": \"application/json\",\n },\n body: JSON.stringify({ username }),\n });\n\n const data = await response.json();\n\n if (!response.ok) {\n throw new Error(data.error || \"Failed to update username\");\n }\n\n onUpdate({ ...user, username });\n setIsEditing(false);\n } catch (err) {\n console.error(\"Error updating username:\", err);\n setError(err instanceof Error ? err.message : \"Failed to update username\");\n } finally {\n setIsSubmitting(false);\n }\n };\n\n return (\n
