Node

Static methods

Retrieval methods

Node.ancestor(root: Node, path: Path) => Ancestor

Get the node at a specific path, asserting that it is an ancestor node. If the specified node is not an ancestor node, throw an error.

Node.ancestors(root: Node, path: Path, options?) => Generator<NodeEntry<Ancestor>>

Return a generator of all the ancestor nodes above a specific path. By default, the order is bottom-up, from lowest to highest ancestor in the tree, but you can pass the reverse: true option to go top-down.
Options: {reverse?: boolean}

Node.child(root: Node, index: number) => Descendant

Get the child of a node at the specified index.

Node.children(root: Node, path: Path, options?) => Generator<NodeEntry<Descendant>>

Iterate over the children of a node at a specific path.
Options: {reverse?: boolean}

Node.common(root: Node, path: Path, another: Path) => NodeEntry

Get an entry for the common ancestor node of two paths.

Node.descendant(root: Node, path: Path) => Descendant

Get the node at a specific path, asserting that it's a descendant node.

Node.descendants(root: Node, options?) => Generator<NodeEntry<Descendant>>

Return a generator of all the descendant node entries inside a root node. Each iteration will return a NodeEntry tuple consisting of [Node, Path].
Options: {from?: Path, to?: Path, reverse?: boolean, pass?: (node: NodeEntry => boolean)}

Node.elements(root: Node, options?) => Generator<ElementEntry>

Return a generator of all the element nodes inside a root node. Each iteration will return an ElementEntry tuple consisting of [Element, Path]. If the root node is an element, it will be included in the iteration as well.
Options: {from?: Path, to?: Path, reverse?: boolean, pass?: (node: NodeEntry => boolean)}

Node.first(root: Node, path: Path) => NodeEntry

Get the first node entry in a root node from a path.

Node.fragment(root: Node, range: Range) => Descendant[]

Get the sliced fragment represented by the range.

Node.get(root: Node, path: Path) => Node

Get the descendant node referred to by a specific path. If the path is an empty array, get the root node itself.

Node.last(root: Node, path: Path) => NodeEntry

Get the last node entry in a root node at a specific path.

Node.leaf(root: Node, path: Path) => Text

Get the node at a specific path, ensuring it's a leaf text node. If the node is not a leaf text node, throw an error.

Node.levels(root: Node, path: Path, options?) => Generator<NodeEntry>

Return a generator of the nodes in a branch of the tree, from a specific path. By default, the order is top-down, from the lowest to the highest node in the tree, but you can pass the reverse: true option to go bottom-up.
Options: {reverse?: boolean}

Node.nodes(root: Node, options?) => Generator<NodeEntry>

Return a generator of all the node entries of a root node. Each entry is returned as a [Node, Path] tuple, with the path referring to the node's position inside the root node.
Options: {from?: Path, to?: Path, reverse?: boolean, pass?: (node: NodeEntry => boolean)}

Node.parent(root: Node, path: Path) => Ancestor

Get the parent of a node at a specific path.

Text methods

Methods related to Text.

Node.string(root: Node) => string

Get the concatenated text string of a node's content. Note that this will not include spaces or line breaks between block nodes. This is not intended as a user-facing string, but as a string for performing offset-related computations for a node.

Node.texts(root: Node, options?) => Generator<NodeEntry<Text>>

Return a generator of all leaf text nodes in a root node.
Options: {from?: Path, to?: Path, reverse?: boolean, pass?: (node: NodeEntry => boolean)}

Check methods

Methods used to check some attribute of a Node.

Node.has(root: Node, path: Path) => boolean

Check if a descendant node exists at a specific path.

Node.isNode(value: any) => value is Node

Check if a value implements the Node interface.

Node.isNodeList(value: any) => value is Node[]

Check if a value is a list of Node objects.

Node.matches(root: Node, props: Partial<Node>) => boolean

Check if a node matches a set of props.
