📄 Description

Summary

Add raw provider response to OAuth2Tokens interface to expose additional provider-specific fields.

Changes Made

  • Enhanced OAuth2Tokens interface: Added an optional raw field to store the complete response from OAuth provider's token endpoint
  • Updated token handling: Modified getOAuth2Tokens() and refreshAccessToken() functions to include raw response data
  • Improved documentation: Added JSDoc comments explaining the purpose and usage of the new raw field

Motivation

OAuth providers often return additional fields in their token responses that are specific to their platform (e.g., openid, open_id, unionid for various providers). Currently, better-auth only extracts standard OAuth2 fields, potentially losing valuable provider-specific information that developers might need.

Benefits

  • Enhanced flexibility: Developers can now access all provider-specific fields returned by OAuth providers
  • Better debugging: Raw response data helps with troubleshooting OAuth integration issues
  • Future-proof: Supports new fields that providers might add without requiring library updates
  • Backward compatible: The new field is optional and doesn't break existing implementations

Files Modified

  • types.ts - Added raw field to OAuth2Tokens interface
  • utils.ts - Updated getOAuth2Tokens() to include raw data
  • refresh-access-token.ts - Updated token refresh logic to include raw data

Testing

This change maintains full backward compatibility as the new field is optional. Existing code will continue to work unchanged while new implementations can optionally access the raw provider response.

Summary by cubic

Added a raw field to the OAuth2Tokens interface to include the full provider token response, making provider-specific fields available to developers.

  • New Features
    • getOAuth2Tokens and refreshAccessToken now return the full raw response from the OAuth provider in the raw field.
