June 2026 monthly summary for govuk-one-login repos (ipv-core-front, ipv-stubs, ipv-core-back). Focused on delivering secure, maintainable, and user-friendly identity verification flows and stubs. Key outcomes include strengthened security posture, improved navigability, and increased reliability through testing and code quality investments. What was delivered (business value): - Reduced risk and improved stability by upgrading dependencies, enhancing security tooling, and aligning runtime environments across front-end, stubs, and back-end components. - Improved user journey and maintainability by restructuring URL paths and cleaning obsolete pages, decreasing support overhead and future maintenance costs. - Increased confidence in UI rendering and visual consistency via snapshot tests and updated testing framework. - Strengthened code quality and consistency through linting and refactors, enabling easier future changes. Key Achievements (top 5): - Security and Infrastructure Upgrades across ipv-core-front: npm audit fixes, node version pinning, and Mocha upgrade (commits: 982803a16c870f7dd58112b6b46f78b8a23d6b3c; aba268ab7a85a97edef607d55ecab880f9004f38; d5302351e73a373627b50370114e97b49e602ac3; 34eb17c3e44e33f783f3bd8f062d3fa7478e7f7d). - URL Structure Cleanup: renamed KBV-related pages to no-photo-id-web-find-another-way and photo-id-web-find-another-way, and removed unused resources to improve navigation and reduce maintenance (commits: 27819e2d23e67625d4eaa1bd1d4b832f457dd4cd; 3cd0a432f40cdf888876bfc3c667b50d786bef0e). - Testing Enhancements: upgraded Mocha and added snapshot validation to ensure UI rendering consistency (commit: 061e0a26151a5dd896bb17f18450df6fd7399136). - Code Quality and Formatting Cleanups: refactored constants for readability and enforced linting to improve maintainability (commit: eeb07462a692431bddb8bbdb8cd3d2e75ce8be26). - Bug Fixes and Security Patches across stubs and back-end: restricted VC validation to request VCs in ipv-stubs; fixed security vulnerabilities via dependency updates; corrected expired license redirect flow in ipv-core-back (commits: 860a81f6442bc20ac70291f456ac855b6db177fb; a495dac8d3b5e0604155de021400c86a270cfddc; a513ac8c7962d413821b9f4c6cdc38700c1bb4da). Overall impact and accomplishments: - Significantly reduced security risk through automated audit fixes and dependency hygiene, enabling smoother downstream releases. - Increased user satisfaction and lower maintenance costs through clearer navigation and stable UI rendering checks. - Enabled faster, safer iteration with higher-confidence deployments thanks to linting, refactors, and pact library improvements. Technologies/skills demonstrated: - Node.js/npm, npm audit, dependency management, and environment hardening. - Front-end refactoring, URL design, and page lifecycle management. - Mocha testing, snapshot testing, and UI validation. - Linting, code style standardization, and constants extraction for readability. - Pact library upgrade and reliability improvements for contract testing.

February 2026: Delivered a major migration of the API gateway in govuk-one-login/ipv-stubs from Java-based Lambdas to TypeScript Lambdas, including restructuring event triggers, removing Java dependencies, standardizing lambda configuration, and consolidating resources. Introduced CIMIT_PARAM_BASE_PATH across all Lambdas to unify base path configuration and improve deployment consistency. Implemented JWT expiration improvements by using current time in seconds for the exp payload, reducing token drift. Fixed asynchronous loop handling to ensure all async operations are awaited and properly logged, eliminating race conditions. Standardized issuanceDate formatting to ISO date strings (YYYY-MM-DDTHH:MM:SSZ) across affected files for data consistency and downstream processing. These changes reduce runtime dependencies, improve reliability, token validity, and data integrity, and streamline CI/CD, with clearer ownership and easier maintenance.
