Database Dialects

Schema generation supports:

• sqlite
• postgresql
• mysql

Set the dialect via NuxtHub config:

export default defineNuxtConfig({
  hub: {
    db: { dialect: 'postgresql' },
  },
})

The generated schema is written to .nuxt/better-auth/schema.<dialect>.ts and merged into NuxtHub.

If you use non‑sqlite dialects, verify your Better Auth adapter configuration in your app, as only sqlite is currently tested by default.
