February 2025 performance summary across alphagov/forms-admin and alphagov/forms-runner. Delivered secure review environment features, improved review-app UX for PR notifications, and streamlined local development, while addressing a critical Rails runtime issue to improve reliability. Key outcomes: - Security and access: Implemented Basic Authentication for Review Environments in the forms-admin app by configuring Traefik with ECS task label-based credentials; credentials are managed externally in forms-deploy for secure review environments. - PR deployment and developer UX: Enhanced Review Apps PR notifications by using human-readable PR URLs in comments, ensuring the review app URL is included, and adding a direct link to the Review Apps wiki for guidance. - Local development parity: Updated API connectivity for Review Apps to point the Forms API base URL to localhost:9292, enabling consistent local development and testing across related tasks. - Reliability improvement: Fixed a critical AbstractController::DoubleRenderError in forms-runner by adding explicit return statements in PageController#show to prevent multiple renders after redirects, addressing a Sentry-reported issue. Impact: - Reduced time-to-ship for review apps by streamlining environment setup and feedback loops. - Lowered risk of runtime errors that could disrupt review cycles and PR validation. - Improved developer productivity through clearer PR communication and local development parity. Technologies/skills demonstrated: - Ruby on Rails controller flow and lifecycle, REST API integration, and error handling - Traefik proxy configuration and ECS-based credential management - Local development workflows and environment parity - Debugging and issue remediation informed by Sentry signals
