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
Name | Type | Description |
---|---|---|
_config | EditorConfig | allows access to things like the EditorTheme (to apply classes) during reconciliation. |
_editor | LexicalEditor | allows access to the editor for context during reconciliation. |
Returns
HTMLElement

lexical/src/LexicalNode.ts:746
createParentElementNode
▸ createParentElementNode(): ElementNode
The creation logic for any required parent. Should be implemented if isParentRequired returns true.
Returns
Defined in
lexical/src/LexicalNode.ts:1019
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
Defined in
lexical/src/LexicalNode.ts:776
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.
Returns

, _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
Name | Type |
---|---|
_prevNode | unknown |
_dom | HTMLElement |
_config | EditorConfig |
Returns
boolean
Defined in
lexical/src/LexicalNode.ts:760
clone
▸ Static
clone(_data
): LexicalNode
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
Name | Type |
---|---|
_data | unknown |
Returns
Defined in
lexical/src/LexicalNode.ts:197
getType
▸ Static
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
lexical/src/LexicalNode.ts:183
importJSON
▸ Static
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
Name | Type |
---|---|
_serializedNode | SerializedLexicalNode |
Returns
Defined in
lexical/src/LexicalNode.ts:799
transform
▸ Static
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 registerNodeTransform API.
Experimental - use at your own risk.
Returns
null
| (node
: LexicalNode
) => void
