Types and constants

Type definitions

Since Codex is written in TypeScript, we often make use of special types for things like complex props. Below is documentation of all public types.

ButtonAction

See ButtonActions.

// Allowed values: 'default', 'progressive', 'destructive'
type ButtonAction = typeof ButtonActions[ number ];

ButtonGroupItem

interface ButtonGroupItem {
	/** Button value or unique identifier */
	value: string | number,
	/**
	 * Display label for the button, or null to show no label (for icon-only buttons).
	 * If the label property is missing, the value property is used as the label.
	 */
	label?: string|null,
	/** Icon to display before the label */
	icon?: Icon,
	/** ARIA label for the button. Used for accessibility for icon-only buttons. */
	ariaLabel?: string,
	/** Whether the button is disabled */
	disabled?: boolean
}

ButtonSize

See ButtonSizes.

// Allowed values: 'medium', 'large'
type ButtonSize = typeof ButtonSizes[ number ];

ButtonType

See ButtonTypes.

// Allowed values: 'button', 'submit', 'reset'
type ButtonType = typeof ButtonTypes[ number ];

ButtonWeight

See ButtonWeights.

// Allowed values: 'normal', 'primary', 'quiet'
type ButtonWeight = typeof ButtonWeights[ number ];

ChipInputItem

interface ChipInputItem {
	value: string,
	icon?: Icon
}

ChipValidator

type ChipValidator = ( value: string ) => boolean;

DialogAction

interface DialogAction {
	label: string,
	disabled?: boolean
}

FloatingMenuOptions

Options which can be passed to the useFloatingMenu composable. The Placement and OffsetOptions types come from the 3rd-party FloatingUI package.

interface FloatingMenuOptions {
	useAvailableWidth?: boolean,
	placement?: Placement,
	offset?: OffsetOptions
}

HTMLDirection

type HTMLDirection = 'ltr' | 'rtl';

I18nFunction

export type I18nFunction = ( messageKey: I18nMessageKey, ...params: any[] ) => string | null;

Icon

Icons are a special type defined in the @wikimedia/codex-icons package. The Icon type is a union of several different other types.

type Icon = SimpleIcon | IconFlipForRtl | IconVariedByDir | IconVariedByLang;

SimpleIcon

Either an object with a path property or a string.

interface PathIcon {
	/**
	 * An SVG path string, e.g. 'M3 3H1v16h18v-2H3z'
	 */
	path: string
}

/**
 * An SVG string, e.g. '<path d="M3 3H1v16h18v-2H3z"/>'. An SVG string may contain multiple tags,
 * e.g. '<circle x="..." y="..." r="..."/><path d="..."/>'. SVG strings should not contain an
 * <?xml ...?> tag or a wrapping <svg> tag.
 */
type SvgIcon = string;

type SimpleIcon = PathIcon | SvgIcon;

IconSize

See IconSizes.

// Allowed values: 'medium', 'small', 'x-small'
type IconSize = typeof IconSizes[ number ];

IconFlipForRtl

An icon with a single SVG that should flip horizontally in RTL mode.

interface IconFlipForRtl {
	/** LTR version of the icon. */
	ltr: SimpleIcon,
	/** Indicates that the icon should be flipped via CSS in RTL mode. */
	shouldFlip: true,
	/**
	 * Language codes that are exceptions to the above property (e.g. the help
	 * icon should flip in RTL mode, but not for Hebrew or Yiddish).
	 */
	shouldFlipExceptions?: string[]
}

IconVariedByDir

An icon that varies per text direction (but can't just be flipped).

interface IconVariedByDir {
	/** Icon for RTL */
	rtl: SimpleIcon,
	/** Icon for LTR */
	ltr: SimpleIcon
}

IconVariedByLang

An icon that varies per language.

interface IconVariedByLang {
	/** HTMLElement.lang code with corresponding icon. */
	langCodeMap: Record<string, SimpleIcon | IconFlipForRtl>,
	/** The default icon. */
	default: SimpleIcon | IconFlipForRtl
}

MenuConfig

interface MenuConfig {
	/** The maximum number of items visible in an expanded menu. */
	visibleItemLimit?: number | null
	/** Whether to show thumbnails (or placeholder). */

	/** Text to be appended to the result's label, e.g. text matching a search query. */
	match?: string,
	description?: string | null,
	/** Lang attributes of text properties. */
	language?: MenuItemLanguageData,
	icon?: Icon,
	thumbnail?: Thumbnail | null,
	/** If URL is included, menu item will be wrapped in an anchor element. */

}

	// Value with units.
	minWidth?: string,
	allowSort?: boolean
}

TableRow

type TableRow = Record<string, any>;

TableRowWithIdentifier

interface TableRowWithIdentifier extends TableRow {
	[TableRowIdentifier]: string
}

	'number'

DebounceInterval

Default length of delay for debouncing, in milliseconds.

Default length of delay for displaying pending state, in milliseconds.

NoInvertClass

A utility class to indicate that certain elements (like thumbnail images) should be excluded from any invert-based "dark mode" theming applied downstream (by the DarkMode extension, for example). No styles are applied to this class within Codex.

const NoInvertClass = 'cdx-no-invert';

Any user of Codex applying an invert-based color theme can use this class to exclude certain elements from color inversion so that they appear in their natural colors.
