If you use jQuery:

    transport: 'xhr', // available transports: 'xhr' and 'iframe'
    uploadUrl: '/upload', // may be function
    withCredentials: true, // add cookies and auth for CORS requests
    progressUrl: '/progress',
    allowedFormats: [
        'application/vnd.ms-excel', // may be MIME type
        'xslx' // may be extension
    ],
    maxSize: null,
    name: "file", // default name of file, used if it not set in input element
    autoUpload: true,
    multiple: false,
    onsuccess: function(response) {
        $('#status').html(response);
    },
    onerror: function(response) {
        $('#status').html(response);
    },
    onprogress: function(loaded, total) {
        // Twitter bootstrap progress
        var persents = Math.ceil(loaded / total * 100);
        var $progress = $('#fileInput')
            .closest('form')
            .find('.progress')
            .show();

        $progress.find('.progress-bar')
            .css({width: persents + "%"})
            .text(persents + '%');

        if(100 === persents) {
            setTimeout(function() {
                $progress.hide();
                $progress.find('.progress-bar')
                    .css({width: "0%"})
                    .text('0%');
            }, 800);
        }
    },
    onchoose: function(event) {
        // event: file input change event
        // this: instance of Upload class 
    },
    oninvalidfile: function(error) {
        // Error may be:
        // * "Multiple upload not allowed": when options.multiple set to false but multiple files uploaded
        // * "Size of file not allowed": when uploaded file size greater than options.maxSize
        // * "Format not allowed": when type of file not patch options.allowedFormats
    },
    onbeforeupload: function() {},
    onafterupload: function() {}
});

If you like plain old JS:

const upload = new Upload(document.getElementById('fileInput'), {
    uploadUrl: '/upload', // may be function
});

Autoupload and manual upload

By default input configured to auto upload file. To disable autoupload, set autoUpload configuration parameter to false, and then call method uploadFile:

const upload = new Upload(
    document.getElementById('fileInput'), 
    {
        autoUpload: false,
    }
);

upload.uploadFile();
