SvelteKit Better Auth (Travel Journal)
This repo is a focused, technical demo of integrating Better Auth with SvelteKit. The UI is a simple travel journal, but the real goal is showcasing auth flows, email delivery, and database wiring end-to-end.
What this covers
- Better Auth + SvelteKit server integration
- Drizzle adapter with SQLite for persistence
- Email/password, magic link, and email verification flows
- Password reset emails
- Google OAuth (optional)
- Local email capture via Mailpit (optional)
Local development
- Install dependencies:
pnpm install
- Configure environment variables:
cp .env.example .env
Update .env with the required values:
DATABASE_URL=local.db
BETTER_AUTH_SECRET=your-random-secret
BETTER_AUTH_URL=http://localhost:5173
MAILER_HOST=127.0.0.1
MAILER_PORT=1036
MAILER_FROM="Travel Journal <[email protected]>"
GOOGLE_CLIENT_ID=your-google-client-id # optional
GOOGLE_AUTH_SECRET=your-google-client-secret # optional
- (Optional) Start the local email inbox:
pnpm dev:services
Mailpit runs at http://localhost:8036 and listens for SMTP on port 1036.
- Initialize the database:
pnpm db:push
- Start the dev server:
pnpm dev
Open http://localhost:5173 in your browser.
