data class Node(val type: String, val props: NodeProps? = null, val children: List<ChildNode>? = null, val extras: Map<String, <Error class: unknown class>> = emptyMap()) : Map<String, <Error class: unknown class>>

A node in the layout tree. The Map view exposes extras only — unknown keys sitting next to type/props/children — so node["custom-key"] reads a custom attribute while the reserved keys stay typed (type, props, children).

NodeProps

data class NodeProps(val id: String? = null, val className: List<String>? = null, val style: Style? = null, val onClick: Event? = null, val onFocus: Event? = null, val onBlur: Event? = null, val onChange: Event? = null, val extras: Map<String, <Error class: unknown class>> = emptyMap()) : Map<String, <Error class: unknown class>>

A node's props object. The Map view exposes extras only — unknown prop keys — so props["data-test"] reads a custom prop while the reserved keys stay typed (id, className, style, onClick, onFocus, onBlur, onChange).

ObjectFit

enum ObjectFit : Enum<ObjectFit>

ObjectPosition

data class ObjectPosition(val horizontal: ObjectPosition.Horizontal, val vertical: ObjectPosition.Vertical)

Overflow

enum Overflow : Enum<Overflow>

Position

enum Position : Enum<Position>

Spacing

data class Spacing(val top: Length, val right: Length, val bottom: Length, val left: Length)

Box-model spacing (padding/margin) as four explicit sides.

Spec

data class Spec(val version: Int, val style: Map<String, Style>, val breakpoints: List<Breakpoint>, val layout: Node, val handlers: Map<String, <Error class: unknown class>>? = null)

Top-level joy-dom document: the typed mirror of the spec JSON's root object.

Style

data class Style(val position: Position? = null, val display: Display? = null, val boxSizing: BoxSizing? = null, val zIndex: Int? = null, val overflow: Overflow? = null, val top: Length? = null, val left: Length? = null, val bottom: Length? = null, val right: Length? = null, val flexDirection: FlexDirection? = null, val flexGrow: Double? = null, val flexShrink: Double? = null, val flexBasis: FlexBasis? = null, val justifyContent: JustifyContent? = null, val alignItems: AlignItems? = null, val alignSelf: AlignSelf? = null, val flexWrap: FlexWrap? = null, val gap: Length? = null, val rowGap: Length? = null, val columnGap: Length? = null, val order: Int? = null, val width: Length? = null, val maxWidth: Length? = null, val minWidth: Length? = null, val height: Length? = null, val maxHeight: Length? = null, val minHeight: Length? = null, val backgroundColor: Color? = null, val opacity: Double? = null, val padding: Spacing? = null, val margin: Spacing? = null, val borderWidth: Length? = null, val borderColor: Color? = null, val borderStyle: BorderStyle? = null, val borderRadius: BorderRadius? = null, val fontFamily: String? = null, val fontSize: Length? = null, val fontWeight: FontWeight? = null, val fontStyle: FontStyle? = null, val color: Color? = null, val textDecoration: TextDecoration? = null, val textAlign: TextAlign? = null, val textTransform: TextTransform? = null, val lineHeight: Double? = null, val letterSpacing: Length? = null, val objectFit: ObjectFit? = null, val objectPosition: ObjectPosition? = null, val textOverflow: TextOverflow? = null, val whiteSpace: WhiteSpace? = null)
