The package can be used with CJS require or with ES6 import statement:
import X3D from "x_ite";
import traverse from "x3d-traverse";
const Traverse = traverse (X3D);
const canvas = X3D .createBrowser ();
const browser = canvas .browser;
const scene = await browser .createX3DFromURL (new X3D .MFString ("https://create3000.github.io/media/examples/Geometry3D/Box/Box.x3d"));
// Traverse all root nodes and its successors.
for (const node of scene .rootNodes .traverse ())
console .log (node .getNodeTypeName ());

Returns every node on its way through the scene graph tree.
The flags parameter is a number ored, for instance like this: Traverse .ROOT_NODES | Traverse .PROTO_DECLARATIONS.
The return value is an iterator with all traversed object, which can be of type:
