This is a large Vue 3 monorepo (pnpm workspaces + Turborepo) that provides 14 fully functional applications: 7 admin panels (web-*) and 7 public-facing marketing sites (site-*), each built with a different UI framework (Ant Design Vue, Arco Design, Element Plus, iDux, Naive UI, PrimeVue, TDesign). The project demonstrates how to build identical feature sets across multiple UI ecosystems while sharing common business logic, API clients, state management, and build tooling. It includes a Nitro-based mock backend server (apps/backend-mock) for development and a client-side static mock (packages/effects/api/src/static-mock.ts) for GitHub Pages previews. The architecture is modular: shared packages under packages/ (api, request, stores, preferences, styles, types, utils, locales, constants) are consumed by all apps, while internal packages (vite-config, lint-configs, node-utils) provide centralized tooling. Key entry points include each app's main.ts, layout component, and router. Data flows through an Axios-based HTTP client (packages/effects/request) with token injection, Pinia stores for user and app state, and a preferences composable for theme/locale management. External dependencies include Vue 3, Vite 8, TypeScript 6, Tailwind CSS v4, Pinia, Axios, ECharts, and the seven UI libraries. The monorepo is designed as a showcase and boilerplate for enterprise front-end architecture, not a specific product.
