packages/lexical/src/LexicalNode.ts:207

Methods

createDOM

createDOM(_config, _editor): 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.
_editorLexicalEditorallows access to the editor for context during reconciliation.

Returns

HTMLElement

Defined in

packages/lexical/src/LexicalNode.ts:763


createParentElementNode

createParentElementNode(): ElementNode

The creation logic for any required parent. Should be implemented if isParentRequired returns true.

Returns

ElementNode

Defined in

packages/lexical/src/LexicalNode.ts:1042


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 @lexical/html!$generateHtmlFromNodes. You could also use this method to build your own HTML renderer.

Parameters

NameType
editorLexicalEditor

Returns

DOMExportOutput

Defined in

packages/lexical/src/LexicalNode.ts:793


exportJSON

exportJSON(): SerializedLexicalNode

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.

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.

NameType
_prevNodeunknown
_domHTMLElement
_configEditorConfig

Returns

boolean

Defined in

Parameters

NameType
_dataunknown

Returns

LexicalNode

Defined in

packages/lexical/src/LexicalNode.ts:198


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

Defined in

packages/lexical/src/LexicalNode.ts:184


importJSON

importJSON(_serializedNode): LexicalNode

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
_serializedNodeSerializedLexicalNode

Returns

LexicalNode

Defined in

packages/lexical/src/LexicalNode.ts:816


transform

transform(): null | (node: LexicalNode) => void

Registers the returned function as a transform on the node during Editor initialization. Most such use cases should be addressed via the LexicalEditor.registerNodeTransform API.

Experimental - use at your own risk.

Returns

null | (node: LexicalNode) => void

Defined in

packages/lexical/src/LexicalNode.ts:832
