December 2024 Insights for hmcts/pcs-frontend: Delivered core features, stabilized backend integrations, improved testing and observability, and hardened the development and deployment pipeline. The work enhances service health visibility, metadata exposure for integrations, and S2S reliability, while reducing noise and optimizing performance.

November 2024 performance summary for hmcts repos (pcs-frontend; cnp-flux-config). Key features delivered: - Redis connectivity testing and resilience: added tests for Redis connectivity, test scaffolding, error handling, startup/connectivity health checks, and health logging; multiple commits improving test coverage and error handling (e.g., added test redis, test for redis connection, try/catch for redis connection). - Redis health monitoring and health checks enhancements: ongoing improvements to startup Redis connection, health checks, and logging; refined health checks and connection management based on health state. - Flux CD integration for PCS frontend: enabled deployment and management of the PCS frontend via Flux CD with ImagePolicy, ImageRepository, and HelmRelease for pcs-frontend, integrating into the automated deployment pipeline. - PerfTest readiness for PCS stack: created perfTest namespace, enabled secure Flux-based deployment for PCS frontend and API, and configured Azure Workload Identity service account for Key Vault access. - Security hardening, code quality, and docs: removed hard-coded connection strings from secrets; added Application Insights connection string; lint/typing improvements; UI/test alignment fixes; readme updates; yarn directory setup and cleanup; session module tests added/flagged for now. Major bugs fixed: - UI heading alignment adjusted and tests updated accordingly. - Functional test failures resolved and stability improvements implemented via multiple commits. - Stabilization efforts including removal of failing tests and audit/security fixes; environment/version adjustments for compatibility. Overall impact and accomplishments: - Significantly improved reliability and security of Redis integration (startup connectivity, health monitoring, and logging), reducing outage risk in caching and session flows. - Added telemetry readiness (Application Insights) and improved security posture by removing sensitive secrets from config. - Streamlined and automated frontend deployment through Flux CD, enabling safer, faster releases. - Prepared PCS for performance testing with a dedicated perftest environment and secure access to Key Vault. - Improved code quality and stability through linting, typing improvements, and consistent test discipline, including documentation updates. Technologies/skills demonstrated: - Node.js/TypeScript, Redis health checks, startup connectivity tests, logging, and health toggling - Flux CD, Helm, Kubernetes concepts (ImagePolicy, ImageRepository, HelmRelease) - Azure Workload Identity, Key Vault access controls - Application Insights telemetry integration - Linting, typing annotations, test stability and readme documentation

October 2024 — hmcts/pcs-frontend highlights: Delivered code quality and security tooling improvements, and prepared preview environments; stabilized accessibility tests to maintain CI health. Key outcomes: - Code quality and security tooling improvements: standardized linting/config, aligned Jenkinsfile/AppInsights naming, and introduced a yarn audit known-issues tracker. - Accessibility testing stabilization: CI health improved via selective test adjustments, placeholder/dummy tests to keep CI green, and re-enabled validations where feasible. - Preview environment readiness: Redis dependency added for preview deployments and Helm chart versions updated to support preview environments. Business impact: Strengthened code quality gates and security posture, more reliable CI/CD, and faster, safer preview deployments enabling earlier feedback and safer releases. Technologies/skills demonstrated: lint/config standardization, Sonar/AppInsights integration, yarn audit tracking, accessibility testing strategy, Kubernetes/Helm, Redis, and CI stability practices.
