February 2025 performance highlights: Strengthened form reliability and UI consistency across LifeSG web-frontend-engine and LifeSG/react-design-system. The Hidden Field Component received typing standardization and null schema support, with expanded test coverage. A broad V3 RL migration wave modernized inputs and form controls (InputGroup variants, MaskedInput, Timepicker, DateInputs, sliders, ESignature, and related components) and updated design tokens for consistent styling. Theme resilience was improved by fixing missing theme handling in theme helpers. Test quality and tooling were fortified through unit test refactors (getBy over queryBy), type error fixes, and codemod/tsconfig improvements. These efforts reduced runtime errors, accelerated feature delivery, and improved developer productivity through stricter typing and better test coverage.
