Transforms

17min

Transforms are helper functions operating on the document. They can be used in defining your own commands.

Node options
All transforms support a parameter options. This includes options specific to the transform, and general NodeOptions to specify the place in the document that the transform is applied to.
TypeScript
interface NodeOptions {
  at?: Location
  match?: (node: Node) => boolean
  mode?: 'highest' | 'lowest'
  voids?: boolean
}
interface NodeOptions {
  at?: Location
  match?: (node: Node) => boolean
  mode?: 'highest' | 'lowest'
  voids?: boolean
}
﻿
The at option is versatile and can be used to implement more complex transforms. Learn more about the  at  option﻿﻿
When combined with at, match can be powerful. Learn more about the  match  option﻿﻿
Static methods
Node transforms
Transforms that operate on nodes.
Transforms.insertFragment(editor: Editor, fragment: Node[], options?)
Insert of fragment of nodes at the specified location in the document. If no location is specified, insert at the current selection.
Options: {at?: Location, hanging?: boolean, voids?: boolean}
Transforms.insertNodes(editor: Editor, nodes: Node | Node[], options?)
Insert nodes at the specified location in the document. If no location is specified, insert at the current selection. If there is no selection, insert at the end of the document.
Options supported: NodeOptions & {hanging?: boolean, select?: boolean}.
Transforms.removeNodes(editor: Editor, options?)
Remove nodes at the specified location in the document. If no location is specified, remove the nodes in the selection.
Options supported: NodeOptions & {hanging?: boolean}
Transforms.mergeNodes(editor: Editor, options?)
Merge a node at the specified location with the previous node at the same depth. If no location is specified, use the selection. Resulting empty container nodes are removed.
Options supported: NodeOptions & {hanging?: boolean}
Transforms.splitNodes(editor: Editor, options?)
Split nodes at the specified location. If no location is specified, split the selection.
Options supported: NodeOptions & {height?: number, always?: boolean}
Transforms.wrapNodes(editor: Editor, element: Element, options?)
Wrap nodes at the specified location in the element container. If no location is specified, wrap the selection.
Options supported: NodeOptions & {split?: boolean}.
options.mode: 'all' is also supported.
options.split indicates that it's okay to split a node in order to wrap the location. For example, if ipsum was selected in a Text node with lorem ipsum dolar, split: true would wrap the word ipsum only, resulting in splitting the Text node. If split: false, the entire Text node lorem ipsum dolar would be wrapped.
Transforms.unwrapNodes(editor: Editor, options?)
Unwrap nodes at the specified location. If necessary, the parent node is split. If no location is specified, use the selection.
Options supported: NodeOptions & {split?: boolean}. For options.mode, 'all' is also supported.
Transforms.setNodes(editor: Editor, props: Partial<Node>, options?)
Set properties of nodes at the specified location. If no location is specified, use the selection.
Options supported: NodeOptions & {hanging?: boolean, split?: boolean}. For options.mode, 'all' is also supported.
Transforms.unsetNodes(editor: Editor, props: string | string[], options?)
Unset properties of nodes at the specified location. If no location is specified, use the selection.
Options supported: NodeOptions & {split?: boolean}. For options.mode, 'all' is also supported.
Transforms.liftNodes(editor: Editor, options?)
Lift nodes at the specified location upwards in the document tree. If necessary, the parent node is split. If no location is specified, use the selection.
Options supported: NodeOptions. For options.mode, 'all' is also supported.
Transforms.moveNodes(editor: Editor, options)
Move the nodes from an origin to a destination. A destination must be specified in the options. If no origin is specified, move the selection.
Options supported: NodeOptions & {to: Path}. For options.mode, 'all' is also supported.
Selection transforms
Transforms that operate on the document's selection.
Transforms.collapse(editor: Editor, options?)
Collapse the selection to a single point.
Options: {edge?: 'anchor' | 'focus' | 'start' | 'end'}
Transforms.select(editor: Editor, target: Location)
Set the selection to a new value specified by target. When a selection already exists, this method is just a proxy for setSelection and will update the existing value.
Transforms.deselect(editor: Editor)
Unset the selection.
Transforms.move(editor: Editor, options?)
Move the selection's point forward or backward.
Options: {distance?: number, unit?: 'offset' | 'character' | 'word' | 'line', reverse?: boolean, edge?: 'anchor' | 'focus' | 'start' | 'end'}
Transforms.setPoint(editor: Editor, props: Partial<Point>, options?)
Set new properties on one of the selection's points.
Options: {edge?: 'anchor' | 'focus' | 'start' | 'end'}
Transforms.setSelection(editor: Editor, props: Partial<Range>)
Set new properties on an active selection. Since the value is a Partial<Range>, this method can only handle updates to an existing selection. If there is no active selection the operation will be void. Use select if you'd like to create a selection when there is none.
Text transforms
Transforms that operate on text.
Transforms.delete(editor: Editor, options?)
Delete text in the document.
Options: {at?: Location, distance?: number, unit?: 'character' | 'word' | 'line' | 'block', reverse?: boolean, hanging?: boolean, voids?: boolean}
Transforms.insertText(editor: Editor, text: string, options?)
Insert a string of text at the specified location in the document. If no location is specified, insert at the current selection.
Options: {at?: Location, voids?: boolean}
Editor transforms
Transforms.transform(editor: Editor, transform: Transform)
Transform the editor by an operation.
