Greptile Overview

Greptile Summary

This PR adds support for the optional locale parameter to the sendInvitation() and resendInvitation() methods in the WorkOS Node SDK, enabling users to specify the language for invitation emails.

Key Changes:

• Added Locale type with 88 supported language codes (e.g., en, es, fr-CA, zh-CN)
• Updated sendInvitation() to accept optional locale field in the options
• Updated resendInvitation() to accept optional second parameter for options (including locale)
• Maintained full backward compatibility - resendInvitation(id) still works without options
• Added comprehensive test coverage for both methods with locale parameter
• Created proper serializers to transform camelCase to snake_case for API requests

Implementation Quality:

• Clean TypeScript interfaces with proper type safety
• Follows existing codebase patterns and conventions
• Proper separation of concerns with dedicated serializers
• Thorough test coverage including error cases (422 invalid locale)

Confidence Score: 5/5

• This PR is safe to merge with no issues found
• The implementation is well-structured, follows existing patterns, maintains backward compatibility, includes comprehensive tests, and introduces no security concerns. The type-safe Locale union prevents invalid values at compile time.
• No files require special attention
