Click **Remix** and you have a working\nauth-protected app — no setup required.\n\nIt uses [Val Town SQLite](https://docs.val.town/std/sqlite/) for the\nuser/session database and [Val Town Email](https://docs.val.town/std/email/) to\nsend the magic links. **Sending magic links to anyone other than yourself\nrequires [Val Town Pro](https://www.val.town/pricing).**\n\n## Architecture\n\n```mermaid\ngraph LR\n Browser -->|\"GET /\"| Hono[\"index.ts
(Hono server)\"]\n Browser -->|\"/api/auth/*\"| BA[\"Better Auth
handler\"]\n Hono -->|serves| HTML[\"index.html\"]\n HTML -->|loads| Entry[\"index.tsx\"]\n Entry -->|renders| App[\"App.tsx\"]\n App -->|useSession| Client[\"auth-client.ts\"]\n Client -->|fetch| BA\n BA -->|reads/writes| SQLite[(\"std/sqlite\")]\n BA -->|sends magic link| Email[\"std/email\"]\n```\n\n## File structure\n\n```\nindex.ts ← Hono entrypoint; mounts Better Auth at /api/auth/*\nbackend/\n auth.ts ← Better Auth instance (server)\n schema.ts ← Creates the user/session/account/verification tables\nfrontend/\n index.html ← HTML shell (loads Twind + React)\n index.tsx ← React entrypoint (mounts )\n lib/\n auth-client.ts ← Better Auth React client (useSession, signIn, signOut)\n components/\n App.tsx ← Root: shows or based on session\n SignIn.tsx ← Email form that calls signIn.magicLink\n Dashboard.tsx ← Signed-in view with sign-out button\n```\n\n## How auth works\n\n1. User enters their email and submits the form. The client calls\n `authClient.signIn.magicLink({ email })`, which `POST`s to\n `/api/auth/sign-in/magic-link`.\n2. Better Auth generates a token, stores it in the `verification` table, and\n calls our `sendMagicLink` callback in `backend/auth.ts`. The callback uses\n `std/email` to send the link.\n3. User clicks the link, which opens `/api/auth/magic-link/verify?token=…`.\n Better Auth validates the token, creates a row in `session`, sets a secure\n cookie, and redirects to `/`.\n4. Back in React, `useSession()` re-fetches `/api/auth/get-session`, the user\n object becomes available, and `` renders ``.\n\n## Adding more auth methods\n\nBetter Auth has a rich [plugin ecosystem](https://better-auth.com/docs/plugins).\nCommon next steps:\n\n- **Email + password** — flip `emailAndPassword.enabled` to `true` in\n `backend/auth.ts`. No plugin needed.\n- **Social login (Google, GitHub, …)** — add `socialProviders` to your auth\n config and store the client IDs/secrets as env vars. See the\n [social providers docs](https://better-auth.com/docs/concepts/social-providers).\n- **Passkeys, 2FA, organizations** — add the relevant plugin on the server and\n the matching client plugin in `frontend/lib/auth-client.ts`.\n\nAfter enabling new methods, you may need new database columns. See the\n[database concepts](https://better-auth.com/docs/concepts/database) page — for\nSQLite you'll add the columns directly to `backend/schema.ts`.\n\n## Production checklist\n\n- [ ] Set the **`BETTER_AUTH_SECRET`** env var to a random string from\n [`generate-random-signing-key.val.run`](https://generate-random-signing-key.val.run/).\n- [ ] Narrow `baseURL.allowedHosts` in `backend/auth.ts` to the exact hosts you\n serve from (e.g. `[\"myapp.com\", \"*.web.val.run\"]`).\n- [ ] Make sure your Val Town account is on [Pro](https://www.val.town/pricing)\n so emails can be sent to addresses other than your own.\n\n## Notes\n\n- The session cookie defaults to 7 days and refreshes itself.\n- Magic-link tokens expire after 5 minutes and are single-use by default.\n- Better Auth uses Kysely under the hood — Val Town's `std/sqlite` is already an\n `@libsql/client` Client, so we hand it straight to `LibsqlDialect`.
