BlazorBlueprint UI

Build modern Blazor web applications using the current BlazorBlueprint component library.

Repository: https://github.com/blazorblueprintui/ui Documentation: https://blazorblueprintui.com Original Source: https://blazorblueprintui.com/llms.txt Full Bundle: https://blazorblueprintui.com/llms/llms-full.txt

Examples in the refreshed references use the official upstream Bb* naming.

Key Architecture Patterns

Controlled vs uncontrolled state

Uncontrolled:

<BbTabs DefaultValue="overview">...</BbTabs>

Controlled:

<BbTabs @bind-Value="currentTab">...</BbTabs>

Composition pattern

<BbCard>
    <BbCardHeader><BbCardTitle>Title</BbCardTitle></BbCardHeader>
    <BbCardContent>Content</BbCardContent>
    <BbCardFooter>Actions</BbCardFooter>
</BbCard>

AsChild pattern

<BbDialog>
    <BbDialogTrigger AsChild>
        <BbButton Variant="ButtonVariant.Destructive">Delete</BbButton>
    </BbDialogTrigger>
    <BbDialogContent>...</BbDialogContent>
</BbDialog>

Portal and provider pattern

Overlay components render through BbPortalHost. App-wide toasts and service-driven dialogs also need BbToastProvider and BbDialogProvider in the root layout.

Known Pitfalls

These are hard-won constraints — check them before generating any BB component code:

1. No unmatched attribute capture — BB components do not accept arbitrary HTML attributes (@onclick, style, class, etc.) and will throw at runtime. Wrap with a native element instead. See patterns.md § No unmatched attribute capture.

2. Tailwind subset only — BB ships only the utilities its own components use; writing other Tailwind classes silently has no effect. Add missing utilities as custom CSS. See setup.md § Tailwind subset limitation.

3. Lucide icon names change — Several names have been renamed upstream (e.g. check-circle → circle-check, home → house). A broken icon renders ⚠️. Verify names at https://blazorblueprintui.com/llms/icons/lucide.txt. See icons.md § Renamed icons.

4. Auth pages are SSR-only — Login/signup blueprints use [ExcludeFromInteractiveRouting]. Use HTML form POST + [SupplyParameterFromForm]; do not add @rendermode InteractiveServer. See blueprints.md § Auth pages and SSR.

5. BbProvider must be the outermost wrapper — Bootstrap order in App.razor matters: <BbProvider> wraps everything. See setup.md § App.razor bootstrap order.

Workflow

1. Read setup.md for installation and providers.
2. Choose components vs primitives before building custom shells or behavior-heavy surfaces.
3. Pick a category: forms, layout/navigation, overlays, display/data, or charts.
4. Load patterns.md when composing multiple surfaces together.
5. Load blueprints.md when you need a production-shaped screen quickly.
6. Style through theme variables and validate dark mode.

When to Load References

• setup.md: first-time setup, providers, theming, dark mode, icons import questions
• services.md: DI registration differences, ToastService, DialogService, provider requirements
• localization.md: label overrides, IBbLocalizer customization, culture-sensitive component text
• blueprints.md: rapid auth, sidebar, dashboard, data, marketing, or ecommerce screen scaffolding
• primitives.md: headless composition, custom design systems, or behavior-only reuse
• components-forms.md: editing flows, validation, selection, wizards, schema-driven forms
• components-layout.md: shells, responsive navigation, cards, tabs, resizable work areas
• components-overlays.md: dialogs, menus, tooltips, command palettes, toasts
• components-display-data.md: alerts, status display, tables, grids, data views, empty/loading states
• components-charts.md: dashboards, KPI visuals, mixed/composite chart composition
• patterns.md: cross-component conventions and blueprint-first workflows

Blueprints and Primitives

• Blueprints provide ready-to-copy compositions for auth, sidebar shells, dashboards, forms, data screens, marketing, and ecommerce. Read references/blueprints.md for category routing and upstream blueprint entry points.
• Primitives are the headless layer for advanced users who want BlazorBlueprint behavior without the styled component surface. Read references/primitives.md when markup ownership matters more than the default component styling.
