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",[],[195],"31e8bd7c-3949-11f0-817e-9e149126039e","index.tsx","6b75f346-7753-489d-9c23-ca816da6e87a",["D",1748164698080],"script","/** @jsxImportSource https://esm.sh/react@18.2.0 */\nimport { createRoot } from \"https://esm.sh/react-dom@18.2.0/client\";\nimport { App } from \"./components/App.tsx\";\n\nconst initialDataString = document.getElementById(\"initial-data\")!.textContent as string;\nlet initialData = JSON.parse(initialDataString);\n\nconst urlParams = new URLSearchParams(window.location.search);\nconst errorParam = urlParams.get(\"error\");\nif (errorParam === \"invalid_token\" && !initialData.user) {\n initialData.error = \"Invalid or expired magic link.
