ConnectionState

Source on GitHub

The ConnectionState type bundles all information about an ongoing connection. It is returned by the useConnection hook.


type NoConnection = {
  inProgress: false;
  isValid: null;
  from: null;
  fromHandle: null;
  fromPosition: null;
  fromNode: null;
  to: null;
  toHandle: null;
  toPosition: null;
  toNode: null;
};
type ConnectionInProgress = {
  inProgress: true;
  isValid: boolean | null;
  from: XYPosition;
  fromHandle: Handle;
  fromPosition: Position;
  fromNode: NodeBase;
  to: XYPosition;
  toHandle: Handle | null;
  toPosition: Position;
  toNode: NodeBase | null;
};
 
type ConnectionState = ConnectionInProgress | NoConnection;

#`isValid`	`boolean \| null` If a an ongoing connection is above a handle or inside the connection radius, this will be true or false - otherwise null
#`from`	`XYPosition \| null` Returns the xy start position or null if no connection is inprogress.
#`fromHandle`	`Handle \| null` Returns the start handle or null if no connection is inprogress.
#`fromPosition`	`Position \| null` Returns the side (called position) of the start handle or null if no connection is inprogress.
#`fromNode`	`Node \| null` Returns the start node or null if no connection is inprogress.
#`to`	`XYPosition \| null` Returns the xy end position or null if no connection is inprogress.
#`toHandle`	`Handle \| null` Returns the end handle or null if no connection is inprogress.
#`toPosition`	`Position \| null` Returns the side (called position) of the end handle or null if no connection is inprogress.
#`toNode`	`Node \| null` Returns the end node or null if no connection is inprogress.
