FileLoader

A low level class for loading resources with the Fetch API, used internally by most loaders. It can also be used directly to load any file type that does not have a loader.

This loader supports caching. If you want to use it, add THREE.Cache.enabled = true; once to your application.

const loader = new THREE.FileLoader();
const data = await loader.loadAsync( 'example.txt' );
