Methods
afterCloneFrom
▸ afterCloneFrom(prevNode): void
Perform any state updates on the clone of prevNode that are not already
handled by the constructor call in the static clone method. If you have
state to update in your clone that is not handled directly by the
constructor, it is advisable to override this method but it is required
to include a call to super.afterCloneFrom(prevNode) in your
implementation. This is only intended to be called by
$cloneWithProperties function or via a super call.
Parameters
| Name | Type |
|---|---|
prevNode | this |
Returns
void
Example
class ClassesTextNode extends TextNode {
// Not shown: static getType, static importJSON, exportJSON, createDOM, updateDOM
__classes = new Set<string>();
static clone(node: ClassesTextNode): ClassesTextNode {
// The inherited TextNode constructor is used here, so
// classes is not set by this method.
return new ClassesTextNode(node.__text, node.__key);
}
afterCloneFrom(node: this): void {
// This calls TextNode.afterCloneFrom and LexicalNode.afterCloneFrom
// for necessary state updates
super.afterCloneFrom(node);
this.__addClasses(node.__classes);
}
// This method is a private implementation detail, it is not
// suitable for the public API because it does not call getWritable
__addClasses(classNames: Iterable<string>): this {
for (const className of classNames) {
this.__classes.add(className);
}
return this;
}
addClass(...classNames: string[]): this {
return this.getWritable().__addClasses(classNames);
}
removeClass(...classNames: string[]): this {
const node = this.getWritable();
for (const className of classNames) {
this.__classes.delete(className);
}
return this;
}
getClasses(): Set<string> {
return this.getLatest().__classes;
}

createDOM
▸ createDOM(): HTMLElement
Called during the reconciliation process to determine which nodes to insert into the DOM for this Lexical Node.
This method must return exactly one HTMLElement. Nested elements are not supported.
Do not attempt to update the Lexical EditorState during this phase of the update lifecyle.
Returns
HTMLElement

exportDOM
▸ exportDOM(editor): DOMExportOutput
Controls how the this node is serialized to HTML. This is important for copy and paste between Lexical and non-Lexical editors, or Lexical editors with different namespaces, in which case the primary transfer format is HTML. It's also important if you're serializing to HTML for any other reason via $generateHtmlFromNodes. You could also use this method to build your own HTML renderer.
Parameters
| Name | Type |
|---|---|
editor | LexicalEditor |
Returns
Inherited from
Defined in
packages/lexical/src/LexicalNode.ts:902
exportJSON
▸ exportJSON(): SerializedDecoratorBlockNode
Controls how the this node is serialized to JSON. This is important for copy and paste between Lexical editors sharing the same namespace. It's also important if you're serializing to JSON for persistent storage somewhere. See Serialization & Deserialization.
Returns

getClasses
▸ getClasses(): ReadOnlyClasses
Returns an object of classes in the form of prefix-suffix for string values, or just prefix for true boolean values.
Returns
ReadOnlyClasses
The classes object.
Example
const exampleClassesObject = {
bg: 'red', // the node is rendered with class `bg-red`
text: 'green', // node is rendered with class `text-green`,
active: true, // node is rendered with class `active`,
}
// Resulting classes: 'bg-red', 'text-green', and 'active'

importJSON
▸ importJSON(_serializedNode): LexicalNode

null | (node: LexicalNode) => void
