NG-ALAIN is an enterprise-level Angular admin frontend scaffold built on NG-ZORRO Ant Design and the @delon ecosystem. It provides a complete, production-ready architecture with lazy-loaded routing, authentication (JWT), role-based access control (ACL), internationalization (i18n) for multiple languages, theme customization (dark/compact), and a comprehensive set of pre-built pages (dashboards, forms, lists, profiles, settings, etc.). The system uses HTTP interceptors for token refresh and error handling, and includes mock data patterns for development. It is designed as a starting point for enterprise applications, offering reusable layouts, shared modules, and utilities. The codebase is modern, using Angular 21+ standalone components with zoneless change detection, and follows strict coding conventions with ESLint and stylelint. While the primary value is the scaffold itself, several core patterns (HTTP interceptor, startup initializer, mock data architecture) are well-crafted and reusable in other Angular projects.
