Interface FileLoader

const loader = new THREE.FileLoader();
// load a text file and output the result to the console
loader.load(
    'example.txt', // resource URL
    function ( data ) { // onLoad callback
        // output the text to the console
        console.log( data )
    },
    function ( xhr ) { // onProgress callback
        console.log( (xhr.loaded / xhr.total * 100) + '% loaded' );
    },
    function ( err ) { // onError callback
        console.error( 'An error happened' );
    }
);

Note: The cache must be enabled using THREE.Cache.enabled = true; This is a global property and only needs to be set once to be used by all loaders that use FileLoader internally. Cache is a cache module that holds the response from each request made through this loader, so each file is requested once.
