Breadcrumb
Router-neutral breadcrumb trail with decorative separators hidden from accessibility.
Identity
Section titled “Identity”- Category: Navigation & disclosure
- Status: stable public Registry/export-map component family
- Targets: iOS · Android · Web, subject to the compatibility contract
- Prerequisites:
@beemvp/beeui-uiinstalled (or this component’s source copied via the Registry CLI below) and, on Web, the BeeUI Tailwind/Uniwind theme CSS loaded — see Start for full platform setup. - Source:
packages/ui/src/components/breadcrumb.tsx
Import
Section titled “Import”import { Breadcrumb, BreadcrumbItem } from '@beemvp/beeui-ui';There is no documented deep/private source import. For source ownership from a BeeUI checkout:
pnpm beeui add breadcrumbRegistry (used throughout this page) is BeeUI’s source-ownership manifest — registry/registry.json — that the pnpm beeui/@beemvp/beeui-cli CLI reads to copy a component’s real source into your app and rewrite its internal imports; it is not an npm package index. This component’s own Registry entry: registry/registry.json.
Composition and public API
Section titled “Composition and public API”- Family exports:
BreadcrumbBreadcrumbItem- Also routed here, outside the Registry family:
breadcrumb
- Package export subpath:
@beemvp/beeui-ui/breadcrumb
- Also routed here, outside the Registry family:
Exported types: BreadcrumbItemProps, BreadcrumbProps
The generated API inventory is mechanically joined to packages/ui/src/index.ts, Registry metadata, and the component reference contract. Each type’s field table below is parsed directly from that source, not a second hand-maintained copy; for the fuller behavior narrative see the canonical component behavior catalog.
State and behavior contract
Section titled “State and behavior contract”Stateless router-neutral trail; separators between BreadcrumbItems are decorative and hidden from accessibility, BreadcrumbItem renders link semantics for navigable ancestors and non-interactive current-location semantics for the active item, and supplied child keys are preserved when separators are composed in.
BreadcrumbItemProps
Section titled “BreadcrumbItemProps”| Prop | Type | Default | Description |
|---|---|---|---|
children |
React.ReactNode |
— | Content rendered inside this element. The family’s composition section states which children it expects. |
className |
string |
— | Extra utility classes, merged after the component’s own via cn(...), so they win on conflict. An escape hatch for source-owned and application work, not a cross-engine portability guarantee. |
current |
boolean |
false |
Marks this item as the current page: it renders as non-interactive text (even with onPress set) and is exposed as accessibilityState.selected. Defaults to false. |
labelClassName |
string |
— | Extra utility classes for the label text specifically, merged after the component’s own. |
Also carries every prop of Omit<PressableProps, 'accessibilityRole' | 'children' | 'role'> — that upstream contract is not reproduced here.
BreadcrumbProps
Section titled “BreadcrumbProps”| Prop | Type | Default | Description |
|---|---|---|---|
children |
React.ReactNode |
— | Content rendered inside this element. The family’s composition section states which children it expects. |
className |
string |
— | Extra utility classes, merged after the component’s own via cn(...), so they win on conflict. An escape hatch for source-owned and application work, not a cross-engine portability guarantee. |
separator |
React.ReactNode |
— | Rendered between each item, hidden from accessibility. Defaults to › in LTR / ‹ in RTL; pass null to render no separator. |
Also carries every prop of Omit<ViewProps, 'children'> — that upstream contract is not reproduced here.
The executable fixtures below are the source-grounded usage examples; consumers should not infer state ownership from DOM structure or another UI library.
Provider and dependencies
Section titled “Provider and dependencies”- No additional provider is required by this family.
BeeUIProviderremains the recommended application root. - Peer/native dependencies visible to this Registry item:
react,react-native - Registry dependency closure:
core-cn,text,theme,use-direction - Safe-area ownership remains explicit: shell surfaces touching system edges opt into
SafeArea; components do not silently invent app-shell insets. - Web consumers load the BeeUI semantic theme CSS as documented in Web onboarding.
Platform behavior
Section titled “Platform behavior”This family ships no platform-specific file, and its own source takes no Platform branch.
The same public family is exposed across the supported target matrix; meaningful platform differences remain governed by the compatibility contract.
Evidence classes are not equal and this page does not blur them: Web behavior is exercised in a real browser, while iOS and Android carry package/export and native-compile evidence, which is not device-runtime proof. The compatibility contract records which class each claim rests on.
Accessibility
Section titled “Accessibility”- Roles this family assigns:
link,text— set inbreadcrumb.tsxby the components themselves, not by the caller. - Accessibility states and properties it sets:
accessibilityElementsHidden,accessibilityLabel,accessible,disabled,selected— read frombreadcrumb.tsx.
Keyboard/focus behavior, announcements, Dynamic Type/Web zoom, RTL and reduced-motion expectations are not derived here — see Accessibility overview, Keyboard & focus, RTL/localization and Large text & zoom. BeeUI does not claim universal accessibility certification from automated tests.
Styling and theming
Section titled “Styling and theming”- Style axes: none of its own — its appearance comes from tokens and your own classes; it also carries
Omit<PressableProps, 'accessibilityRole' | 'children' | 'role'>,Omit<ViewProps, 'children'>. - Class-name surfaces:
className,labelClassName.
Colors, spacing and typography come from semantic tokens rather than from values written here — see Theming and Density. A className is an escape hatch for source-owned and application work, not a cross-engine portability guarantee.
Executable examples
Section titled “Executable examples”- Primary executable fixture:
apps/showcase/__tests__/logical-direction.test.tsx - Additional fixture:
apps/showcase/__tests__/navigation-data-patterns.test.tsx - Additional fixture:
apps/showcase/component-gallery/component-gallery.tsx - Additional fixture:
apps/showcase/runtime-smoke/l10n-stress-acceptance.tsx
Addressable examples
Section titled “Addressable examples”Each link below opens the Showcase at that exact example, not at the top of the gallery:
The Showcase links demonstrate Web behavior; use the native-preview guide for real simulator/emulator/device paths.
Live Web preview
Section titled “Live Web preview”This frame loads the real BeeUI Web Showcase on demand; it is not a second docs-only implementation. It proves browser behavior only. Use native preview for iOS/Android simulator, emulator or device paths.
Composition anatomy
Section titled “Composition anatomy”- Family root / primary export:
Breadcrumb- Public composition parts / helpers:
BreadcrumbItem
- Exported type surface:
BreadcrumbItemPropsBreadcrumbProps
- Public composition parts / helpers:
The tree above is ordinary document structure so it remains readable with keyboard and assistive technology; it is derived from the real public export family rather than a canvas-only diagram.
Verified example source
Section titled “Verified example source”These are the parts of the typechecked runtime Showcase fixture behind this live preview — apps/showcase/component-gallery/component-gallery.tsx, 1103 lines — where Breadcrumb is actually used: 4 lines in 1 place. Each block is copied verbatim from the line range named above it, so it is the same executable source, not a retelling of it. The rest of that file exercises other families and is not reproduced here.
Imports the examples below need (a filtered subset of the fixture’s own top-level imports):
import { Breadcrumb, BreadcrumbItem } from '@beemvp/beeui-ui'; <Breadcrumb accessibilityLabel="Project breadcrumb"> <BreadcrumbItem onPress={() => undefined}>Projects</BreadcrumbItem> <BreadcrumbItem current>BeeUI</BreadcrumbItem> </Breadcrumb>Open the fixture itself for the full surrounding component. For a smaller app-specific example, start from the imports and fixture-state blocks above and keep only the state your screen owns.
Limitations
Section titled “Limitations”A BreadcrumbItem is interactive only when onPress is a function and current is false — marking an item current silently drops its press handler. The trail itself is not exposed as a navigation landmark or a list: the container is marked as not an accessibility element of its own, which leaves its items exposed but gives the trail no semantics, and only the items carry any.
