📄 Description

closes https://github.com/better-auth/better-auth/issues/6766, https://github.com/orgs/better-auth/projects/6/views/2?pane=issue&itemId=168869122&issue=better-auth%7Cbetter-auth%7C5931

Notes

This PR introduces a new package: drizzle-adapter as @better-auth/drizzle-adapter which will need to be published on npm.
This PR also introduces better-auth/adapters/test-adapter as an export to the better-auth adapter test utility and all of it's tests. The reason I didn't export those functions right under better-auth/adapter was to avoid issues related to those functions needing the vitest import which could be bundled into other code if exported purely under /adapter.

Summary by cubic

Adds first-class support for Drizzle Relations v2 via a new @better-auth/drizzle-adapter/relations-v2 adapter and updates the CLI to generate v2 schema and relations. Enables join queries using Drizzle’s v2 relations without changing your database.

  • New Features

    • New relations-v2 adapter for pg, mysql, and sqlite with optional transactions, camelCase, pluralization, and debug logs.
    • Adapter-powered schema generation (createSchema) that outputs both schema and defineRelations; the CLI now prefers the adapter’s generator when available and falls back to built-ins.

  • Migration

    • Install: npm install @better-auth/drizzle-adapter
    • Update: import { drizzleAdapter } from "@better-auth/drizzle-adapter/relations-v2" and set provider ("sqlite" | "pg" | "mysql").
    • Generate: npx @better-auth/cli generate
    • Drizzle init: pass both schema and relations from the generated file to drizzle()

Written for commit 627eccb7cf. Summary will update on new commits.
