📄 Description

Add earlyRedirect option to OAuth proxy to enable full callback processing on preview servers with separate databases.

The previous OAuth proxy flow processed the callback on the production server and then redirected to the preview server to set cookies. This caused issues when preview deployments used separate databases, as user and session data would be created in the production database, making the preview session invalid. The earlyRedirect option ensures the preview server handles the entire callback, creating data in its own database.

Summary by cubic

Add earlyRedirect to the OAuth proxy so preview servers process the full OAuth callback against their own database. This fixes invalid preview sessions when production and preview use different databases.

  • New Features

    • earlyRedirect option redirects the provider callback from production to the preview server before processing.
    • State package now includes earlyRedirect and previewBaseURL; preview runs the full callback and sets cookies.
    • After-hook skips proxy redirect when processing on preview (prevents double redirects).
    • Added tests and docs for “Early Redirect Mode”.

  • Migration

    • Enable earlyRedirect: true in the OAuth proxy config on both production and preview.
    • Use the same Better Auth secret on both servers.

Written for commit f07c87dfb5. Summary will update on new commits.
