Mar 1, 2025

March 2025 performance summary for the DEFRA forms suite across three repositories (DEFRA/forms-runner, DEFRA/forms-runner-v2, DEFRA/forms-engine-plugin). Delivered targeted features that improve user experience, reliability, and developer productivity, along with critical bug fixes and architectural refinements that enhance maintainability and deployment readiness. Key outcomes: - UX and accessibility: improved form readability by giving labels and legends equal visual weight on complex forms. - Observability and reliability: ensured safe merging of tracing headers in HTTP requests, preserving existing headers and custom ones while enabling consistent tracing across GET, POST, and PUT. - Templating and plugin capabilities: exposed nunjucks liquid helpers, filters, globals, and a preparation method to streamline integration for consumers. - Architecture and performance: overhauled the cache service (dxtCacheService) with configurable cacheName, default to server cache, and exposure via server.plugins state, reducing coupling and improving deployment flexibility. - Project structure and maintainability: consolidated templates under a clearer plugins/engine/views layout to simplify navigation and maintenance. Overall impact: Increased user satisfaction through improved form readability, reduced risk and effort in API integration with safer header handling, and enhanced developer experience via templating improvements and a more configurable caching strategy. These changes support faster delivery cycles, more robust deployments, and easier onboarding for plugin consumers. Technologies and skills demonstrated: UI/UX refinement for form components; HTTP header management and test coverage; Nunjucks templating exposure and preparation workflow; plugin architecture and server plugin state exposure; cache service refactor and configurability; documentation and tests alignment.
