EditorState

EditorState is the top-level state object for the editor.

It is an Immutable Record that represents the entire state of a Draft editor, including:

  • The current text content state
  • The current selection state
  • The fully decorated representation of the contents
  • Undo/redo stacks
  • The most recent type of change made to the contents

Note

You should not use the Immutable API when using EditorState objects. Instead, use the instance getters and static methods below.

Overview

Common instance methods

The list below includes the most commonly used instance methods for EditorState objects.

Static Methods

Properties

Note

Use the static EditorState methods to set properties, rather than using the Immutable API directly. This means using EditorState.set to pass new options to an EditorState instance.

Example

const editorState = EditorState.createEmpty();
const editorStateWithoutUndo = EditorState.set(editorState, {
allowUndo: false,
});

Common Instance Methods

getCurrentContent

getCurrentContent(): ContentState

Returns the current contents of the editor.

getSelection

getSelection(): SelectionState

Returns the current cursor/selection state of the editor.

getCurrentInlineStyle

getCurrentInlineStyle(): DraftInlineStyle

Returns an OrderedSet<string> that represents the "current" inline style for the editor.

This is the inline style value that would be used if a character were inserted for the current ContentState and SelectionState, and takes into account any inline style overrides that should be applied.

getBlockTree

getBlockTree(blockKey: string): List;

Returns an Immutable List of decorated and styled ranges. This is used for rendering purposes, and is generated based on the currentContent and decorator.

At render time, this object is used to break the contents into the appropriate block, decorator, and styled range components.

Static Methods

createEmpty

static createEmpty(decorator?: DraftDecoratorType): EditorState

Returns a new EditorState object with an empty ContentState and default configuration.

createWithContent

static createWithContent(
contentState: ContentState,
decorator?: DraftDecoratorType
): EditorState

Returns a new EditorState object based on the ContentState and decorator provided.

create

static create(config: EditorStateCreationConfig): EditorState

Returns a new EditorState object based on a configuration object. Use this if you need custom configuration not available via the methods above.

push

static push(
editorState: EditorState,
contentState: ContentState,
changeType: EditorChangeType
): EditorState

Returns a new EditorState object with the specified ContentState applied as the new currentContent. Based on the changeType, this ContentState may be regarded as a boundary state for undo/redo behavior.

All content changes must be applied to the EditorState with this method.

To be renamed.

undo

static undo(editorState: EditorState): EditorState

Returns a new EditorState object with the top of the undo stack applied as the new currentContent.

The existing currentContent is pushed onto the redo stack.

redo

static redo(editorState: EditorState): EditorState

Returns a new EditorState object with the top of the redo stack applied as the new currentContent.

The existing currentContent is pushed onto the undo stack.

acceptSelection

static acceptSelection(
editorState: EditorState,
selectionState: SelectionState
): EditorState

Returns a new EditorState object with the specified SelectionState applied, but without requiring the selection to be rendered.

For example, this is useful when the DOM selection has changed outside of our control, and no re-renders are necessary.

forceSelection

static forceSelection(
editorState: EditorState,
selectionState: SelectionState
): EditorState

Returns a new EditorState object with the specified SelectionState applied, forcing the selection to be rendered.

This is useful when the selection should be manually rendered in the correct location to maintain control of the rendered output.

moveSelectionToEnd

static moveSelectionToEnd(editorState: EditorState): EditorState

Returns a new EditorState object with the selection at the end.

Moves selection to the end of the editor without forcing focus.

moveFocusToEnd

static moveFocusToEnd(editorState: EditorState): EditorState

Returns a new EditorState object with selection at the end and forces focus.

This is useful in scenarios where we want to programmatically focus the input and it makes sense to allow the user to continue working seamlessly.

setInlineStyleOverride

static setInlineStyleOverride(editorState: EditorState, inlineStyleOverride: DraftInlineStyle): EditorState

Returns a new EditorState object with the specified DraftInlineStyle applied as the set of inline styles to be applied to the next inserted characters.

set

static set(editorState: EditorState, options: EditorStateRecordType): EditorState

Returns a new EditorState object with new options passed in. The method is inherited from the Immutable record API.

Properties and Getters

In most cases, the instance and static methods above should be sufficient to manage the state of your Draft editor.

Below is the full list of properties tracked by an EditorState, as well as their corresponding getter methods, to better provide detail on the scope of the state tracked in this object.

Note

You should not use the Immutable API when using EditorState objects. Instead, use the instance getters and static methods above.

allowUndo

allowUndo: boolean;
getAllowUndo();

Whether to allow undo/redo behavior in this editor. Default is true.

Since the undo/redo stack is the major source of memory retention, if you have an editor UI that does not require undo/redo behavior, you might consider setting this to false.

currentContent

currentContent: ContentState;
getCurrentContent();

The currently rendered ContentState. See getCurrentContent().

decorator

decorator: ?DraftDecoratorType;
getDecorator()

The current decorator object, if any.

Note that the ContentState is independent of your decorator. If a decorator is provided, it will be used to decorate ranges of text for rendering.

directionMap

directionMap: BlockMap;
getDirectionMap();

A map of each block and its text direction, as determined by UnicodeBidiService.

You should not manage this manually.

forceSelection

forceSelection: boolean;
mustForceSelection();

Whether to force the current SelectionState to be rendered.

You should not set this property manually -- see forceSelection().

inCompositionMode

inCompositionMode: boolean;
isInCompositionMode();

Whether the user is in IME composition mode. This is useful for rendering the appropriate UI for IME users, even when no content changes have been committed to the editor. You should not set this property manually.

inlineStyleOverride

inlineStyleOverride: DraftInlineStyle;
getInlineStyleOverride();

An inline style value to be applied to the next inserted characters. This is used when keyboard commands or style buttons are used to apply an inline style for a collapsed selection range.

DraftInlineStyle is a type alias for an immutable OrderedSet of strings, each of which corresponds to an inline style.

lastChangeType

lastChangeType: EditorChangeType;
getLastChangeType();

The type of content change that took place in order to bring us to our current ContentState. This is used when determining boundary states for undo/redo.

nativelyRenderedContent

nativelyRenderedContent: ?ContentState;
getNativelyRenderedContent()

During edit behavior, the editor may allow certain actions to render natively. For instance, during normal typing behavior in the contentEditable-based component, we can typically allow key events to fall through to print characters in the DOM. In doing so, we can avoid extra re-renders and preserve spellcheck highlighting.

When allowing native rendering behavior, it is appropriate to use the nativelyRenderedContent property to indicate that no re-render is necessary for this EditorState.

redoStack

redoStack: Stack<ContentState>;
getRedoStack()

An immutable stack of ContentState objects that can be resurrected for redo operations. When performing an undo operation, the current ContentState is pushed onto the redoStack.

You should not manage this property manually. If you would like to disable undo/redo behavior, use the allowUndo property.

See also undoStack.

selection

selection: SelectionState;
getSelection();

The currently rendered SelectionState. See acceptSelection() and forceSelection().

You should not manage this property manually.

treeMap

treeMap: OrderedMap<string, List>;

The fully decorated and styled tree of ranges to be rendered in the editor component. The treeMap object is generated based on a ContentState and an optional decorator (DraftDecoratorType).

At render time, components should iterate through the treeMap object to render decorated ranges and styled ranges, using the getBlockTree() method.

You should not manage this property manually.

undoStack

undoStack: Stack<ContentState>;
getUndoStack()

An immutable stack of ContentState objects that can be restored for undo operations.

When performing operations that modify contents, we determine whether the current ContentState should be regarded as a "boundary" state that the user can reach by performing an undo operation. If so, the ContentState is pushed onto the undoStack. If not, the outgoing ContentState is discarded.

You should not manage this property manually. If you would like to disable undo/redo behavior, use the allowUndo property.

See also redoStack.
