The antd-admin repository is a monorepo providing two production-ready admin application templates (basic and with-lingui) and a CLI tool for scaffolding new projects from these templates. Built with React 19, Ant Design 6, TanStack Router & Query, Zustand, Zod, Vite+, MSW, and Playwright, it includes features like JWT authentication, role-based access control, CRUD operations with optimistic updates, URL-synchronized table state, dark theming, and optional i18n via Lingui. The architecture emphasizes modularity, with reusable hooks, components, and mocking utilities that encapsulate complex patterns such as data fetching mutations, schema-aware API mocking, and persistent state management.
