Database integration

Fastest database-backed path

Use NuxtHub.

export default defineNuxtConfig({
  modules: ['@nuxthub/core', '@nuxtjs/better-auth'],
  hub: {
    db: 'sqlite',
  },
})

What the module does with NuxtHub

• reads server/auth.config.ts
• generates auth tables from enabled Better Auth features
• exposes generated schema through #auth/schema
• supports custom atomic secondary storage for session lookup caching

Secondary storage

export default defineNuxtConfig({
  hub: { db: 'sqlite' },
  auth: {
    hubSecondaryStorage: 'custom',
  },
})

Important:

• NuxtHub KV cannot implement Better Auth 1.7's atomic getAndDelete and increment operations, so hubSecondaryStorage: true logs a setup warning and continues without module-provided secondary storage. Sessions use the configured database when one exists. Track native support in nuxt-hub/core#927
• hubSecondaryStorage: 'custom' means you provide an atomic secondaryStorage, such as Redis or Upstash
• use DB-only reads if you prefer stricter read-after-write consistency

Non-NuxtHub setups

If you are not using NuxtHub, configure the Better Auth adapter yourself in server/auth.config.ts and manage schema generation separately.
