Constructor​

new HeadingNode(tag?, key?): HeadingNode

Defined in: packages/lexical-rich-text/src/index.ts:241

Parameters​
tag?​

HeadingTagType = 'h1'

key?​

string

Returns​

HeadingNode

Overrides​

ElementNode.constructor

Methods​

afterCloneFrom()​

afterCloneFrom(prevNode): void

Defined in: packages/lexical-rich-text/src/index.ts:236

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​
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;
  }
}
Overrides​

ElementNode.afterCloneFrom

collapseAtStart()​

collapseAtStart(): true

Defined in: packages/lexical-rich-text/src/index.ts:398

Returns​

true

Overrides​

ElementNode.collapseAtStart

createDOM()​

createDOM(config): HTMLElement

Defined in: packages/lexical-rich-text/src/index.ts:258

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 lifecycle.

Parameters​
config​

EditorConfig

Returns​

HTMLElement

Overrides​

ElementNode.createDOM

exportDOM()​

exportDOM(editor): DOMExportOutput

Defined in: packages/lexical-rich-text/src/index.ts:328

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​
editor​

LexicalEditor

Returns​

DOMExportOutput

Overrides​

ElementNode.exportDOM

exportJSON()​

exportJSON(): SerializedHeadingNode

Defined in: packages/lexical-rich-text/src/index.ts:364

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​

SerializedHeadingNode

Overrides​

ElementNode.exportJSON

extractWithChild()​

extractWithChild(): boolean

Defined in: packages/lexical-rich-text/src/index.ts:408

Returns​

boolean

Overrides​

ElementNode.extractWithChild

getTag()​

getTag(): HeadingTagType

Defined in: packages/lexical-rich-text/src/index.ts:246

Returns​

HeadingTagType

insertNewAfter()​

insertNewAfter(selection?, restoreSelection?): HeadingNode | ParagraphNode

Defined in: packages/lexical-rich-text/src/index.ts:372

Parameters​
selection?​

RangeSelection

restoreSelection?​

boolean = true

Returns​

HeadingNode | ParagraphNode

Overrides​

ElementNode.insertNewAfter

setTag()​

setTag(tag): this

Defined in: packages/lexical-rich-text/src/index.ts:250

Parameters​
tag​

HeadingTagType

Returns​

this

updateDOM()​

updateDOM(prevNode, dom, config): boolean

Defined in: packages/lexical-rich-text/src/index.ts:270

Called when a node changes and should update the DOM in whatever way is necessary to make it align with any changes that might have happened during the update.

Returning "true" here will cause lexical to unmount and recreate the DOM node (by calling createDOM). You would need to do this if the element tag changes, for instance.

Parameters​
prevNode​

this

dom​

HTMLElement

config​

EditorConfig

Returns​

boolean

Overrides​

ElementNode.updateDOM

updateFromJSON()​

updateFromJSON(serializedNode): this

Defined in: packages/lexical-rich-text/src/index.ts:358

Update this LexicalNode instance from serialized JSON. It's recommended to implement as much logic as possible in this method instead of the static importJSON method, so that the functionality can be inherited in subclasses.

The LexicalUpdateJSON utility type should be used to ignore any type, version, or children properties in the JSON so that the extended JSON from subclasses are acceptable parameters for the super call.

If overridden, this method must call super.

Parameters​
serializedNode​

LexicalUpdateJSON<SerializedHeadingNode>

Returns​

this

Example​
class MyTextNode extends TextNode {
  // ...
  static importJSON(serializedNode: SerializedMyTextNode): MyTextNode {
    return $createMyTextNode()
      .updateFromJSON(serializedNode);
  }
  updateFromJSON(
    serializedNode: LexicalUpdateJSON<SerializedMyTextNode>,
  ): this {
    return super.updateFromJSON(serializedNode)
      .setMyProperty(serializedNode.myProperty);
  }
}
Overrides​

ElementNode.updateFromJSON

clone()​

static clone(node): HeadingNode

Defined in: packages/lexical-rich-text/src/index.ts:232

Clones this node, creating a new node with a different key and adding it to the EditorState (but not attaching it anywhere!). All nodes must implement this method.

Parameters​
node​

HeadingNode

Returns​

HeadingNode

Overrides​

ElementNode.clone

getType()​

static getType(): string

Defined in: packages/lexical-rich-text/src/index.ts:228

Returns the string type of this node. Every node must implement this and it MUST BE UNIQUE amongst nodes registered on the editor.

Returns​

string

Overrides​

ElementNode.getType

importDOM()​

static importDOM(): DOMConversionMap | null

Defined in: packages/lexical-rich-text/src/index.ts:274

Returns​

Overrides​

ElementNode.importDOM

importJSON()​

static importJSON(serializedNode): HeadingNode

Defined in: packages/lexical-rich-text/src/index.ts:352

Controls how the this node is deserialized from JSON. This is usually boilerplate, but provides an abstraction between the node implementation and serialized interface that can be important if you ever make breaking changes to a node schema (by adding or removing properties). See Serialization & Deserialization.
