@express-document-sdk / VisualNode
Class: VisualNode
A "node" represents an object in the scenegraph, the document's visual content tree. This class represents any node that can be visually perceived in the content. Most visual content is a subclass of the richer Node class which extends VisualNode with more properties, but the overall ArtboardNode container only supports the VisualNode APIs (and higher-level more abstract containers like PageNode extend only the minimal BaseNode class).
Some VisualNodes might have a non-visual parent such as a PageNode.

Accessors
addOnData
• get addOnData(): AddOnData
IMPORTANT: This is currently experimental only and should not be used in any add-ons you will be distributing until it has been declared stable. To use it, you will first need to set the experimentalApis flag to true in the requirements section of the manifest.json.
Get AddOnData reference for managing the private metadata on this node for this add-on.
Returns
allChildren
• get allChildren(): Readonly<Iterable<BaseNode>>
Returns a read-only list of all children of the node. General-purpose content containers such as ArtboardNode or
GroupNode also provide a mutable ContainerNode.children list. Other nodes with a more specific structure can
hold children in various discrete "slots"; this allChildren list includes all such children and reflects their
overall display z-order.
Although BaseNode's allChildren may yield other BaseNodes, the subclasses Node and ArtboardNode override allChildren to guarantee all their children are full-fledged Node instances.
Returns
Readonly<Iterable<BaseNode>>
boundsLocal
• get boundsLocal(): Readonly<Rect>
The bounding box of the node, expressed in the node's local coordinate space (which may be shifted or rotated relative to its parent). Generally matches the selection outline seen in the UI, encompassing the vector path "spine" of the shape as well as its stroke, but excluding effects such as shadows.
The top-left corner of the bounding box corresponds to the visual top-left corner of the node, but this value is not necessarily (0,0) – this is especially true for Text and Path nodes.
Returns
Readonly<Rect>
centerPointLocal
• get centerPointLocal(): Readonly<Point>
Position of the node's centerpoint in its own local coordinate space, i.e. the center of the boundsLocal box.
Returns
Readonly<Point>
id
• get id(): string
A unique identifier for this node that stays the same when the file is closed & reopened, or if the node is moved to a different part of the document.
Returns
string
parent
• get parent(): undefined | BaseNode
The node's parent. The parent chain will eventually reach ExpressRootNode for all nodes that are part of the document content.
Nodes that have been deleted are "orphaned," with a parent chain that terminates in undefined without reaching the
root node. Such nodes cannot be selected, so it is unlikely to encounter one unless you retain a reference to a node
that was part of the document content earlier. Deleted nodes can be reattached to the scenegraph, e.g. via Undo.
Returns
undefined | BaseNode
topLeftLocal
• get topLeftLocal(): Readonly<Point>
Position of the node's top-left corner in its own local coordinate space, equal to (boundsLocal.x, boundsLocal.y). If the node is rotated, this is not the same as the top-left corner of boundsInParent.
Returns
Readonly<Point>
type
• get type(): SceneNodeType
The node's type.
Returns
visualRoot
• get visualRoot(): VisualNode
The highest ancestor that still has visual presence in the document. Typically an Artboard, but for orphaned content, it will be the root of the deleted content (which might be this node itself).
Nodes that are both in the same visualRoot subtree lie within the same "visual space" of the document's structure. Nodes that are in different visual roots have no spatial relation to one another; there is no meaningful comparison or conversion between the bounds or coordinate spaces of such nodes.
Returns
Methods
localPointInNode()
• localPointInNode(localPoint, targetNode): Readonly<Point>
Convert a point given in the node’s local coordinate space to a point in the coordinate space of the target node. Both nodes must share the same visualRoot, but can lie anywhere within that subtree relative to one another (the target node need not be an ancestor of this node, nor vice versa).
Parameters
• localPoint: Point
• targetNode: VisualNode
Returns
Readonly<Point>
removeFromParent()
• removeFromParent(): void
Removes the node from its parent - effectively deleting it, if the node is not re-added to another parent before the document is closed.
If parent is a basic ContainerNode, this is equivalent to node.parent.children.remove(node). For nodes with other
child "slots," removes the child from whichever slot it resides in, if possible. Throws if the slot does not permit
removal. No-op if node is already an orphan.
Returns
void
