Mar 1, 2025March 2025 performance summary for sparcs-kaist/clubs: Delivered API exposure and developer experience enhancements, strengthened reliability, and improved observability. Key outputs include an OpenAPI example for API exposure with client guidance, updated API documentation (CLB-001) and Swagger docs for member-registration, and domain metadata with sort order. Production safety improvements included hiding mock endpoints to prevent mock data leakage. Observability was enhanced via a dedicated userinfo logger and standardized JSON-formatted logs. Stability and resilience were boosted through dependency fixes, improved error handling (including 400 responses), login flow adjustments to Kaist IAM, and more robust error-page redirection. These changes reduce integration risk for external clients, improve deployment safety, and enable faster onboarding and maintenance.
