• Next.js API route mounted at /api/auth/*

Setup

1. Install dependencies:

npm install

2. Create a .env.local file:

DATABASE_URL=postgres://USER:PASSWORD@HOST:5432/DB_NAME
BETTER_AUTH_SECRET=replace-with-a-long-random-secret

3. Start the dev server:

npm run dev

Notes

• This project uses a PostgreSQL connection via pg.
• Make sure your database is reachable from the app.
• If you need migrations/seeding, run them per your better-auth setup.
