onEnd?: (rootNode?: IPackageNode) => void;

Called when all nodes are visited and tried resolving.

  onEnd(rootNode) {
    if (rootNode) console.info('rootNode', rootNode);
  }
});

onError?: (error: NodeJS.ErrnoException) => void;

Called every time an error occurs while traversing.

walkPackageGraph('/path/to/start', {
  onError(error) {
    console.error('onError', error.code, error.path, error.message);
  }
});

onResolve?: (resolvedNode: IPackageNode) => void;

Called every time a package node resolves all of it's dependencies.

walkPackageGraph('/path/to/start', {
  onResolve(node) {
    console.info('onResolve', node.id, node.path, node.dependencies);

});

onUnresolve?: (unresolvedNode: IPackageNode, unresolvedDependencyNames: string[]) => void;

Called every time a package node has failed resolving it's dependency.

walkPackageGraph('/path/to/start', {
  onUnresolve(node, unresolvedNames) {
    console.info('onUnresolve', node.path, unresolvedNames);
  }
});

onVisit?: (visitedNode: IPackageNode) => void;

Called every time a package node has been visited.
