When production and preview servers have different databases, the default OAuth proxy flow doesn't work because the session/user data is created on the production server's database. This adds a new 'earlyRedirect' option that redirects the OAuth callback from the production server to the preview server BEFORE processing, allowing the preview server to run the full callback logic against its own database. Changes: - Add 'earlyRedirect' option to OAuthProxyOptions - Add 'earlyRedirect' and 'previewBaseURL' fields to OAuthProxyStatePackage - Add early redirect before hook to detect and redirect callbacks - Update after hook to skip proxy redirect when processing on preview - Add comprehensive tests for early redirect functionality - Update documentation with new option and 'Early Redirect Mode' section Co-authored-by: bekacru <bekacru@gmail.com>

About the Project
Better Auth is framework-agnostic authentication (and authorization) library for TypeScript. It provides a comprehensive set of features out of the box and includes a plugin ecosystem that simplifies adding advanced functionalities with minimal code in a short amount of time. Whether you need 2FA, multi-tenant support, or other complex features. It lets you focus on building your actual application instead of reinventing the wheel.
Why Better Auth
Authentication in the TypeScript ecosystem is a half-solved problem. Other open-source libraries often require a lot of additional code for anything beyond basic authentication. Rather than just pushing third-party services as the solution, I believe we can do better as a community—hence, Better Auth.
