Worked on the cloudflare/workers-oauth-provider repository to enhance the re-authorization flow by introducing a configurable batch size for revoking existing grants, addressing the risk of excessive KV reads and potential throttling during mass revocations. Implemented a new option, revokeExistingGrantsBatchSize, within CompleteAuthorizationOptions, allowing per-page fetches to be bounded while maintaining full revocation behavior. The feature was developed using TypeScript and focused on backend development and API design, with comprehensive tests ensuring both default and custom batch sizes function as intended. All changes preserved backward compatibility, aligning with established batch-processing patterns and maintaining reliability for existing OAuth integrations.
