BootstrapBlazor is a comprehensive, enterprise-class Blazor UI component library built on Bootstrap 5. It provides over 100 reusable components including tables, dialogs, forms, charts, navigation, and media elements, all with extensive localization support (Chinese/English) and JavaScript interop for rich client-side behavior. The library follows a consistent architecture: each component inherits from BootstrapComponentBase, uses a CssBuilder for CSS class construction, and optionally loads a dedicated JS module via the JSModuleAutoLoader attribute. Services like DialogService, ToastService, and DrawerService follow a callback-based pattern (BootstrapServiceBase) for decoupled UI interactions. The repository also includes a full demo server (BootstrapBlazor.Server) that showcases every component with live examples, sample data services, and API controllers for authentication, file upload, and real-time communication (SignalR, TCP sockets). External dependencies include Bootstrap CSS, FontAwesome/Material Design icons, Floating UI for dropdown positioning, and several third-party JS libraries (Chart.js, Plyr, etc.). The codebase is well-tested with bUnit and xUnit, and is actively maintained with frequent releases and a large contributor community.
