Fields

Usage

This type accepts a generic type argument of custom nodes types. See this section in our TypeScript guide for more information.

onNodesChange is now called with a NodeChangeset instead of a plain NodeChange[] array. Apply it with the changeset’s own applyTo() method:

const onNodesChange: OnNodesChange = (changes) => {
  nodes = changes.applyTo(nodes);
};
