Functions
$canShowPlaceholder
▸ $canShowPlaceholder(isComposing): boolean
Determines if the input should show the placeholder. If anything is in in the root the placeholder should not be shown.
Parameters
| Name | Type | Description |
|---|---|---|
isComposing | boolean | Is the editor in composition mode due to an active Input Method Editor? |
Returns
boolean
true if the input should show the placeholder, false otherwise.

$canShowPlaceholderCurry
▸ $canShowPlaceholderCurry(isEditorComposing): () => boolean
Returns a function that executes $canShowPlaceholder
Parameters
| Name | Type | Description |
|---|---|---|
isEditorComposing | boolean | Is the editor in composition mode due to an active Input Method Editor? |
Returns
fn
A function that executes $canShowPlaceholder with arguments.

$findTextIntersectionFromCharacters
▸ $findTextIntersectionFromCharacters(root, targetCharacters): null | { node: TextNode ; offset: number }
Finds a TextNode with a size larger than targetCharacters and returns the node along with the remaining length of the text.
Parameters
| Name | Type | Description |
|---|---|---|
root | RootNode | The RootNode. |
targetCharacters | number | The number of characters whose TextNode must be larger than. |
Returns
null | { node: TextNode ; offset: number }
The TextNode and the intersections offset, or null if no TextNode is found.

$isRootTextContentEmpty
▸ $isRootTextContentEmpty(isEditorComposing, trim?): boolean
Determines if the root has any text content and can trim any whitespace if it does.
Parameters
| Name | Type | Default value | Description |
|---|---|---|---|
isEditorComposing | boolean | undefined | Is the editor in composition mode due to an active Input Method Editor? |
trim | boolean | true | Should the root text have its whitespaced trimmed? Defaults to true. |
Returns
boolean
true if text content is empty, false if there is text or isEditorComposing is true.
Defined in
packages/lexical-text/src/isRootTextContentEmpty.ts:16
$isRootTextContentEmptyCurry
▸ $isRootTextContentEmptyCurry(isEditorComposing, trim?): () => boolean
Returns a function that executes $isRootTextContentEmpty
Parameters
| Name | Type | Description |
|---|---|---|
isEditorComposing | boolean | Is the editor in composition mode due to an active Input Method Editor? |
trim? | boolean | Should the root text have its whitespaced trimmed? Defaults to true. |
Returns
fn
A function that executes $isRootTextContentEmpty based on arguments.
▸ (): boolean
Returns
boolean

$rootTextContent
▸ $rootTextContent(): string
Returns the root's text content.
Returns
string
The root's text content.

packages/lexical-text/src/rootTextContent.ts:14
registerLexicalTextEntity
▸ registerLexicalTextEntity<T>(editor, getMatch, targetNode, createNode): () => void[]
Returns a tuple that can be rested (...) into mergeRegister to clean up node transforms listeners that transforms text into another node, eg. a HashtagNode.
Type parameters
| Name | Type |
|---|---|
T | extends TextNode |
Parameters
| Name | Type | Description |
|---|---|---|
editor | LexicalEditor | The lexical editor. |
getMatch | (text: string) => null | EntityMatch | Finds a matching string that satisfies a regex expression. |
targetNode | Klass<T> | The node type that contains text to match with. eg. HashtagNode |
createNode | (textNode: TextNode) => T | A function that creates a new node to contain the matched text. eg createHashtagNode |
Returns
() => void[]
An array containing the plain text and reverse node transform listeners.
Example
useEffect(() => {
return mergeRegister(
...registerLexicalTextEntity(editor, getMatch, targetNode, createNode),
);
}, [createNode, editor, getMatch, targetNode]);
Where targetNode is the type of node containing the text you want to transform (like a text input), then getMatch uses a regex to find a matching text and creates the proper node to include the matching text.
