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

NameType
prevNodethis

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;
}
}

collapseAtStart

collapseAtStart(): boolean

Returns

boolean

Overrides

ElementNode.collapseAtStart

Defined in

packages/lexical/src/nodes/LexicalParagraphNode.ts:191


createDOM

createDOM(config): 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.

Parameters

NameTypeDescription
configEditorConfigallows access to things like the EditorTheme (to apply classes) during reconciliation.

Returns

HTMLElement

Overrides

ElementNode.createDOM

Defined in

packages/lexical/src/nodes/LexicalParagraphNode.ts:101


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

NameType
editorLexicalEditor

Returns

DOMExportOutput

Overrides

ElementNode.exportDOM

Defined in

packages/lexical/src/nodes/LexicalParagraphNode.ts:127


exportJSON

exportJSON(): SerializedParagraphNode

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

SerializedParagraphNode

Overrides

ElementNode.exportJSON

Defined in

packages/lexical/src/nodes/LexicalParagraphNode.ts:164

Parameters

Returns

Parameters

setTextStyle

setTextStyle(style): this

Parameters

NameType

Returns

packages/lexical/src/nodes/LexicalParagraphNode.ts:83


updateDOM

updateDOM(prevNode, dom, config): boolean

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

NameType
prevNodeParagraphNode
domHTMLElement
configEditorConfig

Returns

boolean

Overrides

ElementNode.updateDOM

Defined in

packages/lexical/src/nodes/LexicalParagraphNode.ts:110


clone

clone(node): ParagraphNode

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

NameType
nodeParagraphNode

Returns

ParagraphNode

Overrides

ElementNode.clone

Defined in

packages/lexical/src/nodes/LexicalParagraphNode.ts:89


getType

getType(): string

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

Defined in

packages/lexical/src/nodes/LexicalParagraphNode.ts:58


importDOM

importDOM(): null | DOMConversionMap

Returns

null | DOMConversionMap

Overrides

ElementNode.importDOM

Defined in

packages/lexical/src/nodes/LexicalParagraphNode.ts:118


importJSON

importJSON(serializedNode): ParagraphNode

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.

Parameters

NameType
serializedNodeSerializedParagraphNode

Returns

ParagraphNode

Overrides

ElementNode.importJSON

Defined in

packages/lexical/src/nodes/LexicalParagraphNode.ts:155
