GFast is a full-stack, modular admin panel built with GoFrame v2.10 and Vue3. It provides a RESTful API backend for managing users, roles, departments, menus, dictionaries, configuration, logs, and system monitoring. The architecture follows a layered pattern: API definitions (api/v1), controllers (internal/app/*/controller), business logic (internal/app/*/logic), data access objects (dao), and service interfaces. Authentication uses JWT (gfast-token) and authorization uses Casbin with RBAC. Caching is abstracted via gfast-cache supporting memory or Redis. The system includes a code generator, scheduled tasks, and an OpenAPI/Swagger endpoint. External dependencies include MySQL, Redis, Casbin, and ip2region for IP geolocation.
