app.js

var tus = require("tus-js-client");

$('#uploadBtn').change(function () {
    var file = this.files[0];
    if (typeof file === "undefined") {
        return;
    }

    // some validations goes here using `file.size` & `file.type`

    var upload = new tus.Upload(file, {
        // https://github.com/tus/tus-js-client#tusdefaultoptions
        endpoint: "/tus",

<?php

class TusController {

    public function indexAction() {
        // Disable views/layout the way suites your framework
        $server = new TusPhp\Tus\Server(); // Using File Cache (over Redis) for simpler setup
        $server->setApiPath('/tus/index') // tus server endpoint.
                ->setUploadDir('/tmp'); // uploads dir.
        $response = $server->serve();
