fix: update styling for mostly-used components with new greyscale tokens (combobox, dialog, input, layerCard, select & tabs) as well as homegrid and component preview backgrounds.

Remove es2022 build target that caused Jest/babel-jest test failures in stratus

Add radio card appearance via appearance="card" prop on Radio.Group and Radio.Item. Cards display a bordered, selectable container with title and description. Also adds description prop to Radio.Item for helper text. Supports vertical and horizontal orientations, error state, and disabled state.

Expose Chart optionUpdateBehavior to control how ECharts applies option updates; notMerge now defaults to false.

Add neutral variant to Switch component and improve accessibility

• New variant="neutral" option: monochrome switch with squircle shape, matching the design from stratus
• Improved off-state visibility for default variant with darker background/ring colors
• Removed error variant (not useful for toggle switches)
• Added defensive fallback so invalid variant values don't cause runtime crashes

removed outline-none to bring back focus states on all buttons

Fix flaky vitest "Closing rpc while fetch was pending" error in deep-imports test

Fix InputArea label click not focusing textarea. Use FieldBase.Control with render callback to properly associate the label with the textarea element.

Fix TypeScript return types for ShikiProvider and CodeHighlighted components.

Changed return type from ReactNode to React.JSX.Element to resolve JSX compatibility errors. This fixes issues when consuming these components in projects with stricter TypeScript configurations (e.g., skipLibCheck: false), where ReactNode was incorrectly inferred as a valid JSX element return type.

Fix table header font size to ensure consistent rendering across dashboards with different default font sizes

Add dedicated lark-placeholder text color token and use it for Input, InputArea, SensitiveInput, and CommandPalette placeholder text. The new token provides better visual distinction between placeholder and active text in both light and dark modes.

Replace the package-level ESLint pass with Oxlint JS plugin coverage for the remaining jsx-a11y rules, and pin the library build to es2022 with a post-build browser-compat test that blocks newer runtime APIs from shipping in dist.

fix(Select): prevent chevron overflow with long multi-select values

Added min-w-0 truncate to the value element and shrink-0 to the chevron icon so that long option names truncate gracefully instead of pushing the chevron outside the select bounds.

Fix combobox caret icon to use text-lark-subtle with fill-current instead of invalid fill-lark-subtle token

fix TimeseriesChart brush cursor not activating when loading prop transitions from true to false

add xAxisTickFormat, yAxisTickFormat, and tooltipValueFormat props to TimeseriesChart; deprecate yAxisTickLabelFormat

Deprecation: yAxisTickLabelFormat is deprecated

If you were using yAxisTickLabelFormat to customize tooltip output, switch to tooltipValueFormat.

Before:

<TimeseriesChart yAxisTickLabelFormat={(v) => `${v} req/s`} />

After:

<TimeseriesChart tooltipValueFormat={(v) => `${v} req/s`} />

Fix combobox caret icon visibility by using fill-lark-subtle instead of fill-lark-ring

reorganize greyscale tokens and update color preferences

updated button styles for outline and secondary

Fix Jest module resolution failures and reduce Shiki bundle size

Jest Fix:

• Add chunkFileNames config to prevent double-dash filenames (e.g., combobox--ec3iibR.js) that Jest cannot resolve
• Move chunks to dist/chunks/ subdirectory for cleaner structure

Bundle Size Reduction:

• Switch from full Shiki bundle to fine-grained imports via shiki/core
• Reduce from ~300 language/theme chunks to ~16 bundled languages
• Total JS files reduced from 358 to ~163 (54% reduction)

Supported Languages: javascript, typescript, jsx, tsx, json, jsonc, html, css, python, yaml, markdown, graphql, sql, bash, shell, diff

Breaking Change:

• BundledLanguage type is now deprecated, use SupportedLanguage instead
• Only the languages listed above are bundled; other Shiki languages are no longer available out of the box

Fix npm publish failure by removing cross-package dependency from prepublish hook

Select: Improved label API to match Input component pattern

• hideLabel is now deprecated. When label is provided, the label is visible by default (previously hidden by default).
  • For visible labels: <Select label="Country" /> (no changes needed if you were using hideLabel={false})
  • For hidden labels: Use <Select aria-label="Select a country" /> instead of <Select label="Country" hideLabel={true} />
• Bug fix: Placeholder text now displays correctly when using object map items format (e.g., items={{ a: "Option A" }}). Previously, placeholders only worked with array format items.

Backward compatibility: hideLabel={true} still works but shows a deprecation warning in development. Existing code using hideLabel={false} requires no changes.

Migration guide:

// Before (label hidden by default)
<Select label="Country" />                    // label was sr-only
<Select label="Country" hideLabel={false} />  // label was visible

// After (label visible by default, matching Input)
<Select label="Country" />                    // label is now visible
<Select aria-label="Country" />               // use aria-label for hidden labels

Add optional id prop to Flow.Node for stable node identification and connector test IDs

Avoid adding multiple toasts with the same ID. Use a subtle bump animation when a toast with an existing ID is added.

Fix theme token flicker by generating stable light/dark fallback variables with safer scope and layer precedence.

fix: add defensive styles to prevent global CSS pollution

Problem

When Lark components are used in applications with aggressive global styles (e.g., Stratus's cfBaseStyles layer), certain elements get polluted:

• label { margin-bottom: 1rem } adds unwanted margins to all labels
• button { background: gray } affects unstyled button wrappers (e.g., tooltip triggers)
• a { color: var(--text-color-primary) } can override link colors if the consuming app defines --text-color-primary differently

Solution

Add defensive Tailwind utility classes directly to components. These:

1. Reset commonly-polluted properties to safe defaults
2. Use cn() (tailwind-merge) so consumer styles via className still override them
3. Are no-ops in clean CSS environments (no visual change in Lark docs)

Changes

Label margins (m-0)

• Label: labelVariants() now includes m-0
• Field: FieldBase.Label gets m-0
• Checkbox: label wrapper gets m-0
• Radio: label wrapper gets m-0
• Switch: label wrapper gets m-0

Button trigger resets

• Tooltip trigger (when !asChild): bg-transparent border-none shadow-none p-0 m-0 h-auto min-h-0 leading-[0] inline-flex items-center
• Collapsible trigger: bg-transparent border-none shadow-none p-0 m-0

Link color namespace fix

• Link: Changed from text-primary to text-lark-link to avoid collision with consuming apps that define --text-color-primary differently

Label tooltip composition

• Label: Tooltip trigger now uses <Button variant="ghost" size="xs" shape="square"> with asChild, leveraging composition instead of relying on defensive resets

Docs

Added "Custom Trigger" section to Tooltip docs demonstrating that className can fully override defensive styles when not using asChild.

fix(dropdown): use Base UI CheckboxItemIndicator for proper accessibility

Replace custom Checkbox component with Base UI's CheckboxItemIndicator in DropdownMenuCheckboxItem. The previous implementation nested an interactive Checkbox inside the menuitemcheckbox role, causing duplicate accessibility labels. CheckboxItemIndicator is automatically aria-hidden and only renders when checked, following the standard Base UI pattern.

Fix Field error message line height by adding leading-snug for consistent text spacing

Improve info banner dark mode contrast for WCAG AA compliance. Changes lark-info from blue-700 (L=48.8%) to blue-400 (L=70.7%), achieving 7.97:1 contrast ratio against the banner background.

Fix Combobox.TriggerValue icon misalignment caused by inherited line-height

The caret icon span was inheriting line-height from the parent button's text-base class, causing the span's height to exceed the icon's height (e.g., 21.5px vs 16px). The icon sits at the top of the span by default, so when the span is centered via top-1/2 -translate-y-1/2, the icon appears offset.

Added flex items-center to the icon wrapper to ensure proper vertical centering regardless of inherited styles. This matches the pattern used in TriggerInput.

fix(Pagination): use aria-label instead of label for PageSize select

The Select component now shows visible labels by default. Since Pagination.PageSize already displays "Per page:" text next to the select, the internal Select should use aria-label for accessibility without showing a duplicate visible label.

chore(toast): replace inline XIcon with Phosphor icon

Prevent password managers autofilling Pagination input field

fix(tabs): improve focus ring and hover styling

• Fixed focus ring to use proper ring-lark-ring token instead of browser default blue
• Segmented variant: inset focus ring to avoid overlap with adjacent tabs, hidden on active tab
• Underline variant: added padding for better focus ring spacing around text
• Added subtle hover states for both variants

fix(Tabs): pass TabItem render prop through to Base UI for custom tab rendering (e.g., link-based tabs)

Add Shiki-powered CodeHighlighted component for syntax highlighting

• New entry point: @lark-ui/core/code - keeps Shiki out of main bundle
• ShikiProvider: Lazy-loads Shiki on first render, shares instance across all children
• CodeHighlighted: Syntax highlighting with line numbers, line highlighting, copy button
• Server utilities: @lark-ui/core/code/server for SSR/static highlighting
• Themes: Ships with github-light and vesper defaults, supports any Shiki theme
• i18n: Customizable labels via provider or per-component
• CSS customization: --lark-code-highlight-bg variable for highlight color
• Deprecates: Legacy Code and CodeBlock components (will be removed in v2)

feat(combobox): add size prop with xs, sm, base, lg variants matching Input component

feat(flow): make nested lists work inside parallel nodes

Add role prop to Dialog component supporting both "dialog" (default) and "alertdialog" ARIA roles

New Feature:

• Dialog.Root now accepts a role prop to specify the dialog's ARIA semantics
• When role="alertdialog" is used, the dialog uses Base UI's AlertDialog primitives for proper accessibility
• This provides correct screen reader announcements for confirmation and destructive action dialogs

When to use role="alertdialog":

• Destructive actions (delete, discard, remove)
• Confirmation flows requiring explicit user acknowledgment
• Actions that cannot be undone
• Critical warnings or errors

Example:

// Standard dialog (default)
<Dialog.Root>
  <Dialog.Trigger render={(p) => <Button {...p}>Edit</Button>} />
  <Dialog>...</Dialog>
</Dialog.Root>

// Alert dialog for destructive actions
<Dialog.Root role="alertdialog">
  <Dialog.Trigger render={(p) => <Button variant="destructive" {...p}>Delete</Button>} />
  <Dialog>...</Dialog>
</Dialog.Root>

Add TimeseriesChart component with ECharts integration, supporting legends, gradient fills, custom axis formatting, loading skeleton state, and configurable color palettes.

feat(select): auto-render options from items prop when children omitted

The Select component now automatically renders Select.Option elements from the items prop when children are not explicitly provided.

Add missing success background and tint semantic color tokens (bg-lark-success, bg-lark-success-tint) for parity with info, warning, and danger. Fix text-lark-success dark mode contrast by using green-400 instead of green-500. Add new success Badge variant for positive state indicators.

fix(breadcrumbs): improve mobile breadcrumb readability

breadcrumbs now render a compact mobile trail for deeper hierarchies by collapsing early levels to ... and keeping the trailing path visible. labels in breadcrumb links and the current page now truncate correctly to prevent stacking or overlap on narrow viewports.

fix(badge): prevent crash when unknown variant is passed

Add defensive fallback to primary variant when an unrecognized variant string is provided to Badge component. This prevents "Cannot read properties of undefined (reading 'classes')" errors when consumers use a variant that doesn't exist in their installed version.

fix(code): Fix CodeHighlighted dark mode, layout, and SSR issues

• Fix dark mode: Make <pre> background transparent so container's bg-lark-base handles theming and border-radius is respected
• Fix layout: Wrap Shiki output in overflow container to prevent line highlight negative margins from being clipped
• Fix width: Add w-full to container for proper full-width display
• Fix SSR: Remove "use client" directive from @lark-ui/core/code/server entry point so server utilities work in RSC/SSR contexts

fix(CommandPalette): add explicit text-base class to Item component for consistent 14px font size

Fix Select to render description and error when hideLabel is true

Previously, the description and error props were silently ignored when hideLabel was true (the default). Now, helper text and error messages display correctly even when the label is visually hidden.

Fix TypeScript errors when consumers type-check their projects with lark installed.

Previously, TypeScript would attempt to type-check raw .tsx and .ts source files shipped in the package (block sources in dist/src/blocks/, ai/schemas.ts, and scripts/theme-generator/*.ts), causing build failures in downstream projects.

This change:

• Moves block source files to a separate dist/blocks-source/ directory
• Compiles ai/schemas.ts and scripts/theme-generator/*.ts to JavaScript
• Updates package exports to point to compiled .js files with proper .d.ts types

fix(inputs): expand small control hit areas

Fix pagination component to properly wrap numbers in tabular-nums class for consistent number alignment. Both the page range and total count now use tabular numerals.

Simplify Select placeholder implementation by using Base UI's native placeholder prop on SelectBase.Value instead of manually injecting placeholder items into the items array. This provides a cleaner, more intuitive API that aligns with standard HTML select behavior while maintaining backward compatibility with the null-value placeholder pattern.

fix(breadcrumbs): enhance mobile breadcrumb display for better readability

Add variant="compact" prop to Table.Header for a more condensed header style

Fix Combobox group label styling to use semantic token and correct padding

Standardize z-index usage with isolation containment

• Add isolation: isolate to components with internal stacking (Tabs, MenuBar, InputGroup, Flow/Parallel)
• Simplify internal z-index values to z-0/z-1/z-2 instead of arbitrary values like z-10/z-20
• Remove superfluous z-10 from CommandPalette List
• Update Toast viewport to z-1 (matching Base UI's documented pattern)
• Update ClipboardText viewport to use isolate instead of z-50

This prevents z-index values from leaking outside component boundaries.

feat(dropdown): add LinkItem for navigation links and fix icon rendering

New Features:

• Add DropdownMenu.LinkItem for navigation links (semantic <a> element with proper menu item behavior)
• Upgrade @base-ui/react from 1.0.0 to 1.2.0
• Add new primitives: csp-provider and drawer from Base UI 1.2.0

Bug Fixes:

• Fix icon prop not rendering on DropdownMenu.Item when no href is provided

Deprecations:

• href prop on DropdownMenu.Item is deprecated. Use DropdownMenu.LinkItem instead.

Migration:

// Before (deprecated)
<DropdownMenu.Item href="https://example.com">Link</DropdownMenu.Item>

// After (recommended)
<DropdownMenu.LinkItem href="https://example.com" target="_blank">
  Link
</DropdownMenu.LinkItem>

DropdownMenu.LinkItem gives you full control over link attributes (target, rel, etc.) without the component making assumptions about your intent.

Add positionMethod prop to Popover.Content to control CSS positioning strategy. Use "fixed" when the popover needs to escape stacking contexts (e.g., inside sticky headers). Defaults to "absolute".

Improve Flow diagram components with disabled node support and better connector rendering:

• Add disabled prop to FlowNode for greying out connectors
• Add align prop to FlowParallelNode for start/end alignment
• Improve connector path rendering with smarter junction detection
• Fix panning behavior to not interfere with node interactions

Refactor Banner component with softer styling and i18n-friendly props

• Added title and description props for structured content with i18n support
• Softened visual appearance: reduced background opacity (20% -> 10%), muted border colors
• Text now uses text-lark-default for readability, with colored icons for variant indication
• Added iconClasses to variant config for per-variant icon coloring
• Component now uses forwardRef and sets displayName per conventions
• Deprecated children and text props in favor of title/description
• Legacy children prop still works for backwards compatibility

Fix Checkbox ring color to use ring-lark-contrast when checked or indeterminate

Fix Combobox dropdown scrolling regression and improve scroll behavior.

Bug fix: The overflow-hidden class was accidentally re-introduced during a semantic color token migration, which overrode overflow-y-auto and caused dropdown content to be clipped instead of scrollable.

Improvement: Restructured Combobox.Content to use flexbox layout so that when using Combobox.Input inside the dropdown (searchable popup pattern), the input stays fixed at the top while only the list scrolls. Previously, the entire popup content would scroll together.

Scrollbar fix: Moved horizontal padding from the popup container to individual child components, so the scrollbar renders flush with the popup edge instead of being inset (which was clipping the checkmark indicators).
