This repository is a monorepo React UI component library consisting of two main packages: `smarthr-ui` (core UI components) and `@smarthr/smarthr-ui-charts` (charting components). It provides a comprehensive set of accessible, internationalizable UI components built with TypeScript, Tailwind CSS, and modern React patterns. The library emphasizes accessibility, theming, and developer experience, with extensive testing (unit, visual regression, E2E) and Storybook documentation. Key architectural features include a design token system, custom hooks for common patterns (useLatest, usePortal), and a focus on composability.
