Methods​

$config()​

$config(): BaseStaticNodeConfig & object & StaticNodeTypeAccessor<"text"> & StaticNodeConfigAccessor<{ extends: typeof LexicalNode; generated: GeneratedJSONFactory; importDOM: { #text: () => object; b: () => object; code: () => object; em: () => object; i: () => object; mark: () => object; s: () => object; span: () => object; strong: () => object; sub: () => object; sup: () => object; u: () => object; }; json: NodeSerializationSchema<TextNode, { detail?: string | number; format?: string | number; mode?: "normal" | "token" | "segmented"; style?: string; text?: string; }>; }> & object & StaticNodeTypeAccessor<"code-highlight"> & StaticNodeConfigAccessor<{ extends: typeof TextNode; generated: GeneratedJSONFactory; json: NodeSerializationSchema<CodeHighlightNode, { highlightType?: string | null; }>; }>

Defined in: packages/lexical-code-core/src/CodeHighlightNode.ts:76

Override this to implement the new static node configuration protocol, this method is called directly on the prototype and must not depend on anything initialized in the constructor. Generally it should be a trivial implementation.

Returns​

BaseStaticNodeConfig & object & StaticNodeTypeAccessor<"text"> & StaticNodeConfigAccessor<{ extends: typeof LexicalNode; generated: GeneratedJSONFactory; importDOM: { #text: () => object; b: () => object; code: () => object; em: () => object; i: () => object; mark: () => object; s: () => object; span: () => object; strong: () => object; sub: () => object; sup: () => object; u: () => object; }; json: NodeSerializationSchema<TextNode, { detail?: string | number; format?: string | number; mode?: "normal" | "token" | "segmented"; style?: string; text?: string; }>; }> & object & StaticNodeTypeAccessor<"code-highlight"> & StaticNodeConfigAccessor<{ extends: typeof TextNode; generated: GeneratedJSONFactory; json: NodeSerializationSchema<CodeHighlightNode, { highlightType?: string | null; }>; }>

afterCloneFrom()​

afterCloneFrom(prevNode): void

Defined in: packages/lexical/src/LexicalNode.ts:1138

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;
}
}

canHaveFormat()​

canHaveFormat(): boolean

Defined in: packages/lexical-code-core/src/CodeHighlightNode.ts:95

Returns​

boolean

true if the text node supports font styling, false otherwise.

Inherited from​

TextNode.canHaveFormat

canInsertTextAfter()​

canInsertTextAfter(): boolean

Defined in: packages/lexical/src/nodes/LexicalTextNode.ts:1004

This method is meant to be overridden by TextNode subclasses to control the behavior of those nodes when a user event would cause text to be inserted after them in the editor. If true, Lexical will attempt to insert text into this node. If false, it will insert the text in a new sibling node.

Returns​

boolean

true if text can be inserted after the node, false otherwise.

Inherited from​

TextNode.canInsertTextAfter

canInsertTextBefore()​

canInsertTextBefore(): boolean

Defined in: packages/lexical/src/nodes/LexicalTextNode.ts:993

This method is meant to be overridden by TextNode subclasses to control the behavior of those nodes when a user event would cause text to be inserted before them in the editor. If true, Lexical will attempt to insert text into this node. If false, it will insert the text in a new sibling node.

Returns​

boolean

true if text can be inserted before the node, false otherwise.

Inherited from​

TextNode.canInsertTextBefore

config()​
Call Signature​

config<Config>(type, config): AbstractStaticNodeConfigRecord<Config>

Defined in: packages/lexical/src/LexicalNode.ts:1065

This is a convenience method for $config that aids in type inference. See LexicalNode.$config for example usage.

An abstract base class that has no concrete node type may pass a well-known symbol (by convention Symbol.for(<NodeClassName>)) instead of a string type to declare configuration shared with its subclasses.

Type Parameters​
Config​

Config extends StaticNodeConfigValue<CodeHighlightNode, string>

Parameters​
type​

symbol

config​

Config

Returns​

AbstractStaticNodeConfigRecord<Config>

Inherited from​

TextNode.config

Call Signature​

config<Type, Config>(type, config): StaticNodeConfigRecord<Type, Config>

Defined in: packages/lexical/src/LexicalNode.ts:1069

This is a convenience method for $config that aids in type inference. See LexicalNode.$config for example usage.

An abstract base class that has no concrete node type may pass a well-known symbol (by convention Symbol.for(<NodeClassName>)) instead of a string type to declare configuration shared with its subclasses.

Type Parameters​
Type​

Type extends string

Config extends StaticNodeConfigValue<CodeHighlightNode, Type>

Parameters​
type​

Type

createDOM()​

createDOM(config): HTMLElement

Defined in: packages/lexical-code-core/src/CodeHighlightNode.ts:99

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

Inherited from​

TextNode.createDOM

createParentElementNode()​

createParentElementNode(): ElementNode

Defined in: packages/lexical-code-core/src/CodeHighlightNode.ts:139

Returns​

ElementNode

Inherited from​

TextNode.createParentElementNode

exportDOM()​

exportDOM(editor): DOMExportOutput

Defined in: packages/lexical/src/nodes/LexicalTextNode.ts:714

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

Inherited from​

TextNode.exportDOM

exportJSON()​
Call Signature​

exportJSON(compact?): SerializedCodeHighlightNode

Defined in: packages/lexical-code-core/src/CodeHighlightNode.ts:54

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.

The base implementation writes every property the node's schema declares (its own and those it inherits), reading each through its getter — get<Prop> by default, or the name recorded with withAccessors. A getter that returns undefined omits its property. Override this only for output a schema can not describe, and call super.exportJSON(compact) when you do.

This may serialize the instance as-is, without resolving the latest version. A property declared with withField is read straight off the node, which is the optimization the serialization walk is built on — every node the walk reaches comes from the EditorState's node map and is already current, so it resolves nothing per node.

So on a reference that a getWritable() (any set<Prop>) has since superseded, this writes pre-mutation values. Which properties do is not something to rely on: a property whose accessor a subclass overrode still goes through that accessor and resolves the latest, so one node can write a current text beside a stale style. Call node.getLatest().exportJSON() whenever you hold such a reference rather than reasoning about which properties resolve.

This is a breaking change. Every property previously went through an accessor, and every accessor resolves getLatest(), so a stale reference exported current values.

Parameters​
compact?​

false

Write the compact form: omit a property the parser derives rather than reads, one whose value is the schema default parsing would restore, and the deprecated version. The two forms describe the same document. A node that overrides this and ignores the flag simply keeps writing the full form, which still parses.

Returns​

SerializedCodeHighlightNode

Inherited from​

TextNode.exportJSON

Call Signature​

exportJSON(compact): SerializedPartial<SerializedCodeHighlightNode>

Defined in: packages/lexical-code-core/src/CodeHighlightNode.ts:55

The compact form omits properties, so what it returns is the partial serialized type — every node-specific property optional — rather than the full one. Passing a boolean whose value is not statically known selects this overload too, which is right: neither form can be promised then.

Parameters​
compact​

boolean

Returns​

SerializedPartial<SerializedCodeHighlightNode>

getDetail()​

getDetail(): number

Defined in: packages/lexical/src/nodes/LexicalTextNode.ts:487

Returns a 32-bit integer that represents the TextDetailTypes currently applied to the TextNode. You probably don't want to use this method directly - consider using TextNode.isDirectionless or TextNode.isUnmergeable instead.

Returns​

number

a number representing the detail of the text node.

Inherited from​

TextNode.getDetail

getDOMSlot()​

getDOMSlot(element): DOMSlot<HTMLElement>

Defined in: packages/lexical/src/LexicalNode.ts:1783

Experimental

Returns a DOMSlot pointing at the content-bearing element of this node's DOM. The default returns a slot wrapping the keyed DOM as-is.

Override this when createDOM returns a wrapper around the content-bearing element (e.g. <span><br/></span> for a styled line break), so selection / reconciliation logic can target the inner element.

ElementNode overrides this to return an ElementDOMSlot with children-management semantics (used by the reconciler to place managed children).

Inherited from​

TextNode.isParentRequired

isSegmented()​

isSegmented(): boolean

Defined in: packages/lexical/src/nodes/LexicalTextNode.ts:538

Inherited from​

TextNode.isSegmented

isSelected()​

isSelected(selection?): boolean

Defined in: packages/lexical/src/LexicalNode.ts:1230

Returns​

boolean

Inherited from​

TextNode.isSelected

isSimpleText()​

isSimpleText(): boolean

Defined in: packages/lexical/src/nodes/LexicalTextNode.ts:581

true if the node is simple text, false otherwise.

Inherited from​

TextNode.isSimpleText

isTextEntity()​

isTextEntity(): boolean

Defined in: packages/lexical/src/nodes/LexicalTextNode.ts:1236

This method is meant to be overridden by TextNode subclasses to control the behavior of those nodes when used with the registerLexicalTextEntity function. If you're using registerLexicalTextEntity, the node class that you create and replace matched text with should return true from this method.

Returns​

boolean

true if the node is to be treated as a "text entity", false otherwise.

Inherited from​

TextNode.isTextEntity

isToken()​

isToken(): boolean

Defined in: packages/lexical/src/nodes/LexicalTextNode.ts:518

Returns whether or not the node is in "token" mode. TextNodes in token mode can be navigated through character-by-character with a RangeSelection, but are deleted as a single entity (not individually by character).

Returns​

boolean

true if the node is in token mode, false otherwise.

Inherited from​

TextNode.isToken

isUnmergeable()​

isUnmergeable(): boolean

Defined in: packages/lexical/src/nodes/LexicalTextNode.ts:557

Returns whether or not the node is unmergeable. In some scenarios, Lexical tries to merge adjacent TextNodes into a single TextNode. If a TextNode is unmergeable, this won't happen.

Returns​

boolean

true if the node is unmergeable, false otherwise.

Inherited from​

TextNode.isUnmergeable

markDirty()​

markDirty(): void

Defined in: packages/lexical/src/LexicalNode.ts:2387

Marks a node dirty, triggering transforms and forcing it to be reconciled during the update cycle.

Returns​

void

Inherited from​

TextNode.markDirty

mergeWithSibling()​

mergeWithSibling(target): TextNode

Defined in: packages/lexical/src/nodes/LexicalTextNode.ts:1181

Merges the target TextNode into this TextNode, removing the target node.

Parameters​
target​

TextNode

the TextNode to merge into this one.

Returns​

TextNode

this TextNode.

Inherited from​

TextNode.mergeWithSibling

remove()​

remove(preserveEmptyParent?): void

Defined in: packages/lexical/src/LexicalNode.ts:1948

Removes this LexicalNode from the EditorState. If the node isn't re-inserted somewhere, the Lexical garbage collector will eventually clean it up.

Parameters​
preserveEmptyParent?​

boolean

If falsy, the node's parent will be removed if it's empty after the removal operation. This is the default behavior, subject to other node heuristics such as ElementNode#canBeEmpty

Returns​

void

Inherited from​

TextNode.remove

replace()​

replace<N>(replaceWith, includeChildren?): N

Defined in: packages/lexical/src/LexicalNode.ts:1965

Replaces this LexicalNode with the provided node, optionally transferring the children of the replaced node to the replacing node.

Named slots are bound to their host node and are never transferred: this node keeps its slot map, so if it is reattached elsewhere (as $wrapNodeInElement does) its slots come with it, and if it stays detached the slot subtrees are garbage-collected along with it. To move a slot value onto another host, use $setSlot explicitly.

Type Parameters​
N​

N extends LexicalNode

Parameters​
replaceWith​

N

The node to replace this one with.

includeChildren?​

boolean

Whether or not to transfer the children of this node to the replacing node.

Returns​

N

setDetail()​

setDetail(detail): this

Defined in: packages/lexical/src/nodes/LexicalTextNode.ts:788

Sets the node detail to the provided TextDetailType or 32-bit integer. Note that the TextDetailType version of the argument can only specify one detail value and doing so will remove all other detail values that may be applied to the node. For toggling behavior, consider using TextNode.toggleDirectionless or TextNode.toggleUnmergeable

Parameters​
detail​

number | TextDetailType

TextDetailType or 32-bit integer representing the node detail.

Returns​

this

this TextNode. // TODO 0.12 This should just be a string.

setMode(type): this

Defined in: packages/lexical/src/nodes/LexicalTextNode.ts:857

Sets the mode of the node.

Note: during IME composition, a segmented TextNode may be temporarily switched to normal mode to preserve the DOM element that the browser's composition tracker is bound to. Subclass transforms or method overrides that assume the node is always in segmented mode should account for this transient state.

Inherited from​

TextNode.setMode

setStyle()​

setStyle(style): this

Defined in: packages/lexical/src/nodes/LexicalTextNode.ts:803

updateDOM()​

updateDOM(prevNode, dom, config): boolean

Defined in: packages/lexical-code-core/src/CodeHighlightNode.ts:109

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

Inherited from​

TextNode.updateDOM

updateFromJSON()​

updateFromJSON(serializedNode): this

Defined in: packages/lexical-code-core/src/CodeHighlightNode.ts:56

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​

LexicalParseJSON<SerializedCodeHighlightNode>

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);
}
}

The whole schema is applied, so a property the JSON omits is set to its schema default rather than left as it is — that is what lets the compact form omit a default-valued property and have parsing restore it. (A flat NodeState is the exception: it is applied only when present.) Pass the node's complete serialized form unless you mean to reset what you leave out.

Inherited from​

TextNode.updateFromJSON

clone()​

static clone(_data): LexicalNode

Defined in: packages/lexical/src/LexicalNode.ts:1029

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​
_data​

unknown

Returns​

LexicalNode

Inherited from​

TextNode.clone

getType()​

static getType(): string

Defined in: packages/lexical/src/LexicalNode.ts:1013

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

Inherited from​

TextNode.getType

importJSON()​

static importJSON(_serializedNode): LexicalNode

Defined in: packages/lexical/src/LexicalNode.ts:1870

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​
_serializedNode​

Omit<SerializedLexicalNode & Partial<SerializedLexicalNode>, "$slots" | "children" | "version"> & object & Record<string, unknown>

Returns​

LexicalNode

Inherited from​

TextNode.importJSON

transform()​

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

Defined in: packages/lexical/src/LexicalNode.ts:1934

Experimental

Defined in: packages/lexical-code-core/src/CodeNode.ts:120

Override this to implement the new static node configuration protocol, this method is called directly on the prototype and must not depend on anything initialized in the constructor. Generally it should be a trivial implementation.

Returns​

BaseStaticNodeConfig & StaticNodeConfigAccessor<{ $transform: { }; extends: typeof LexicalNode; generated: GeneratedJSONFactory; json: NodeSerializationSchema<ElementNode, { direction?: "ltr" | "rtl" | null; format?: "" | "left" | "start" | "center" | "right" | "end" | "justify"; indent?: string | number; textFormat?: string | number; textStyle?: string; }>; }> & object & StaticNodeTypeAccessor<"code"> & StaticNodeConfigAccessor<{ extends: typeof ElementNode; generated: GeneratedJSONFactory; importDOM: { code: (node) => { conversion: (domNode) => DOMConversionOutput; priority: 1; } | null; div: () => object; pre: () => object; table: (node) => { conversion: () => DOMConversionOutput; priority: 3; } | null; td: (node) => { conversion: () => DOMConversionOutput; priority: 3; } | null; tr: (node) => { conversion: () => DOMConversionOutput; priority: 3; } | null; }; json: NodeSerializationSchema<CodeNode, { language?: string | null; theme?: string; }>; }>

afterCloneFrom()​

afterCloneFrom(prevNode): void

Defined in: packages/lexical-code-core/src/CodeNode.ts:212

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);

ElementNode.excludeFromCopy

exportDOM()​

exportDOM(editor): DOMExportOutput

Defined in: packages/lexical-code-core/src/CodeNode.ts:290

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

Inherited from​

ElementNode.exportDOM

exportJSON()​
Call Signature​

exportJSON(compact?): SerializedCodeNode

Defined in: packages/lexical-code-core/src/CodeNode.ts:105

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.

The base implementation writes every property the node's schema declares (its own and those it inherits), reading each through its getter — get<Prop> by default, or the name recorded with withAccessors. A getter that returns undefined omits its property. Override this only for output a schema can not describe, and call super.exportJSON(compact) when you do.

This may serialize the instance as-is, without resolving the latest version. A property declared with withField is read straight off the node, which is the optimization the serialization walk is built on — every node the walk reaches comes from the EditorState's node map and is already current, so it resolves nothing per node.

So on a reference that a getWritable() (any set<Prop>) has since superseded, this writes pre-mutation values. Which properties do is not something to rely on: a property whose accessor a subclass overrode still goes through that accessor and resolves the latest, so one node can write a current text beside a stale style. Call node.getLatest().exportJSON() whenever you hold such a reference rather than reasoning about which properties resolve.

This is a breaking change. Every property previously went through an accessor, and every accessor resolves getLatest(), so a stale reference exported current values.

Parameters​
compact?​

false

Write the compact form: omit a property the parser derives rather than reads, one whose value is the schema default parsing would restore, and the deprecated version. The two forms describe the same document. A node that overrides this and ignores the flag simply keeps writing the full form, which still parses.

Returns​

SerializedCodeNode

Inherited from​

ElementNode.exportJSON

Call Signature​

exportJSON(compact): SerializedPartial<SerializedCodeNode>

Defined in: packages/lexical-code-core/src/CodeNode.ts:106

The compact form omits properties, so what it returns is the partial serialized type — every node-specific property optional — rather than the full one. Passing a boolean whose value is not statically known selects this overload too, which is right: neither form can be promised then.

Parameters​
compact​

boolean

remove()​

remove(preserveEmptyParent?): void

Defined in: packages/lexical/src/LexicalNode.ts:1948

replace()​

replace<N>(replaceWith, includeChildren?): N

Defined in: packages/lexical/src/LexicalNode.ts:1965

Replaces this LexicalNode with the provided node, optionally transferring the children of the replaced node to the replacing node.

Named slots are bound to their host node and are never transferred: this node keeps its slot map, so if it is reattached elsewhere (as $wrapNodeInElement does) its slots come with it, and if it stays detached the slot subtrees are garbage-collected along with it. To move a slot value onto another host, use $setSlot explicitly.

Type Parameters​
N​

Defined in: packages/lexical-code-core/src/CodeNode.ts:107

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​

LexicalParseJSON<SerializedCodeNode>

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);
}
}

The whole schema is applied, so a property the JSON omits is set to its schema default rather than left as it is — that is what lets the compact form omit a default-valued property and have parsing restore it. (A flat NodeState is the exception: it is applied only when present.) Pass the node's complete serialized form unless you mean to reset what you leave out.

Inherited from​

ElementNode.updateFromJSON

clone()​

static clone(_data): LexicalNode

Defined in: packages/lexical/src/LexicalNode.ts:1029

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​
_data​

unknown

Returns​

LexicalNode

Inherited from​

ElementNode.clone

getType()​

static getType(): string

Defined in: packages/lexical/src/LexicalNode.ts:1013

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

Inherited from​

ElementNode.getType

importJSON()​

static importJSON(_serializedNode): LexicalNode

Defined in: packages/lexical/src/LexicalNode.ts:1870

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​
_serializedNode​

Omit<SerializedLexicalNode & Partial<SerializedLexicalNode>, "$slots" | "children" | "version"> & object & Record<string, unknown>

Returns​

LexicalNode

Inherited from​

ElementNode.importJSON

transform()​

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

Defined in: packages/lexical/src/LexicalNode.ts:1934

Experimental

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​

((node) => void) | null

Inherited from​

ElementNode.transform

Interfaces​

CodeIndentConfig​

Defined in: packages/lexical-code-core/src/CodeIndentation.ts:681

Properties​

disabled​

disabled: boolean

Defined in: packages/lexical-code-core/src/CodeIndentation.ts:687

When true, the indent commands are not registered on the editor. This signal can be flipped at runtime to enable or disable indent handling without rebuilding the editor.

escapeWithArrows​

escapeWithArrows: boolean

Defined in: packages/lexical-code-core/src/CodeIndentation.ts:706

When true, this enables the ability to exit a code block that has no adjacent elements using the ArrowLeft/ArrowUp keys if the cursor is at the beginning, or the ArrowRight/ArrowDown keys if the cursor is at the end. When false (default), pressing the arrow keys will not move the cursor if there are no adjacent elements around the code block

tabSize​

tabSize: number | undefined

Defined in: packages/lexical-code-core/src/CodeIndentation.ts:697

When set, treats that many leading spaces on a code line as one indent level for the OUTDENT_CONTENT_COMMAND (Shift+Tab). See registerCodeIndentation. When undefined (the default), only TabNode removal is supported on outdent.

Tab and INSERT_TAB_COMMAND continue to insert a TabNode regardless of this option.

Type Aliases​

SerializedCodeNode​

SerializedCodeNode = Spread<{ language: string | null | undefined; theme?: string; }, SerializedElementNode>

Defined in: packages/lexical-code-core/src/CodeNode.ts:58

Variables​

CodeExtension​

const CodeExtension: LexicalExtension<ExtensionConfigBase, "@lexical/code", unknown, unknown>

Defined in: packages/lexical-code-core/src/CodeExtension.ts:31

Add code blocks to the editor (syntax highlighting provided separately)


CodeIndentExtension​

const CodeIndentExtension: LexicalExtension<CodeIndentConfig, "@lexical/code-indent", NamedSignalsOutput<CodeIndentConfig>, unknown>

Defined in: packages/lexical-code-core/src/CodeIndentation.ts:720

Adds keyboard-driven indentation to code blocks (Tab / Shift+Tab, alt+arrow line shifts, Home/End within a line). Both "@lexical/code-shiki".CodeShikiExtension and "@lexical/code-prism".CodePrismExtension declare this as a dependency, so it is activated automatically alongside either highlighter.

Code blocks without syntax highlighting can use this extension on its own.


DEFAULT_CODE_LANGUAGE​

const DEFAULT_CODE_LANGUAGE: "javascript" = 'javascript'

Defined in: packages/lexical-code-core/src/CodeNode.ts:79

$getCodeLineDirection()​

$getCodeLineDirection(anchor): "ltr" | "rtl" | null

Defined in: packages/lexical-code-core/src/FlatStructureUtils.ts:76

Determines the visual writing direction of a code line.

Scans the line segments (CodeHighlightNode/TabNode) from start to end and returns the first strong direction found ("ltr" or "rtl"). If no strong character is found, falls back to the parent element's direction. Returns null if indeterminate.

Returns​

"ltr" | "rtl" | null


$getEndOfCodeInLine()​

$getEndOfCodeInLine(anchor): TabNode | CodeHighlightNode

Defined in: packages/lexical-code-core/src/FlatStructureUtils.ts:226

Parameters​

Returns​

TabNode | CodeHighlightNode


$getFirstCodeNodeOfLine()​

$getStartOfCodeInLine()​

$getStartOfCodeInLine(anchor, offset): { node: LineBreakNode | TabNode | CodeHighlightNode; offset: number; } | null

Defined in: packages/lexical-code-core/src/FlatStructureUtils.ts:109

Parameters​

anchor​

TabNode | CodeHighlightNode

offset​

number

Returns​

{ node: LineBreakNode | TabNode | CodeHighlightNode; offset: number; } | null


$isCodeHighlightNode()​

$isCodeHighlightNode(node): node is CodeHighlightNode

Defined in: packages/lexical-code-core/src/CodeHighlightNode.ts:163

Parameters​

node​

LexicalNode | CodeHighlightNode | null | undefined

Returns​

node is CodeHighlightNode


$isCodeNode()​

$isCodeNode(node): node is CodeNode

Defined in: packages/lexical-code-core/src/CodeNode.ts:439

Parameters​

node​

LexicalNode | null | undefined

Returns​

node is CodeNode


$outdentLeadingSpaces()​

$outdentLeadingSpaces(node, tabSize, selection): boolean

Defined in: packages/lexical-code-core/src/FlatStructureUtils.ts:269

Strip up to tabSize leading spaces from a CodeHighlightNode that starts a code line, to support outdenting space-indented code lines (e.g. code formatted with prettier). Returns true if any spaces were stripped.

Best-effort: a line with fewer than tabSize leading spaces has all of them stripped, matching VS Code / IntelliJ behavior.

Selection is preserved relative to line content. Anchor/focus offsets pointing into node shift left by the number of stripped characters (clamped to 0). The underlying TextNode mutation does not adjust selection offsets that already point into the old text, so we patch them up explicitly.

Parameters​

node​

CodeHighlightNode

tabSize​

number

selection​

RangeSelection

Returns​

boolean
