📄 Description

auth ts-17

Summary by cubic

Adds built-in support for Cloudflare D1Database so BetterAuth runs natively on Cloudflare Workers with a Kysely dialect and auto-detection. Removes the need for custom adapters and resolves Worker types build issues.

  • New Features

    • Added D1SqliteDialect for Kysely (queries, transactions, introspection).
    • Auto-detects D1 via batch/exec/prepare in getKyselyDatabaseType and createKyselyAdapter; BetterAuthOptions.database accepts D1Database.

  • Dependencies

    • Added @cloudflare/workers-types: optional peerDependency in core and devDependency in kysely-adapter.

Written for commit 313bbcae5ba5d6d79fe2a2f01a57c592685be2cb. Summary will update on new commits.
