After integration of Reuire.js into theme, i found some interested problem. When system include JQuery UI scripts with Require.js support, i catch the error for not existed modules.

Looks in the /wp-includes/js/jquery/ui/ directory i found some files with AMD loading support, but with wrong module names in depending modules.

For example file wp-includes/js/jquery/ui/accordion.min.js contain this substring


but Require.js can't find core or wodget modules. It happen, because by default this modules in wordpress area have names likes "jquery-ui-core" and "jquery-ui-widget"

Please, change all lines in JS files to correct module names, like

Hey there, welcome to trac and thanks for creating a ticket!

These minified JavaScript files are generated during build from the source files, which already include these lines (define(["jquery","./core","./widget"]…)). The source files are the ones you could download on the jQuery UI website. We usually try to avoid editing third-party files.

jquery-ui-widget is only the name of the handle needed for wp_enqueue_script(). How would this affect RequireJS? Would you mind sharing some example code to highlight the problem?

I catched this problem, when i tryed integrate Visual Composer plugin into my own theme with RequireJS. It means, whn i try open Frontend Editor from VC plugin, it trying load UI plugins from existing theme. My code catch all wp_enque_script calls and generate RequireJS config for loading javascript files.


 * That class provide functional for difficult theme settings
class ThemeSettings {

     * Instance of current class
     * @var \ThemeSettings
    protected static $_instance;

     * Containd describe for RequireJS configuration
     * @var array[]
    protected $_scripts = array();

     * Disallow native creation of object
    protected function __construct() {}

     * Generate and return instance of current class
     * @return \ThemeSettings
    public static function getInstance() {
        if (empty(self::$_instance)) {
            self::$_instance = new ThemeSettings();

        return self::$_instance;

     * Add describe of javascript to RequireJS config
     * @param string $handle
     * @param string[] $script
    public function addScript($handle, $script) {
        $this->_scripts[$handle] = $script;

     * Generate config for RequireJS loader
     * @return stdClass
    public function getRequirejsConfig() {
        $config = (object) array('waitSeconds' => 30,'paths' => (object) array(), 'shim' => (object) array());
        foreach ($this->_scripts as $handle => $script) {
            $config->paths->{$handle} = $script->src;

            if (!empty($script->deps)) {
                $config->shim->{$handle} = $script->deps;
            switch($handle) {
                case 'admin-bar': 
                    $config->shim->{$handle} = array('jquery');

        return $config;
     * Get all JS scripts description
     * @return type
    function getScripts() {
        return $this->_scripts;

/* Delayed loading of all JS files */
add_filter('script_loader_tag', function($tag, $handle, $src) {
    if (isAdmin()) return $tag;

    global $wp_scripts;
    ThemeSettings::getInstance()->addScript($handle, (object)array(
        'deps' => $wp_scripts->query($handle, 'registered')->deps,
        'src' => $src,
        'tag' => $tag

    return '';
}, 10, 3);

But when i catch standart the JQuery UI scripts, it try load modules with RequireJS supports and can't find these modules.

I propose to you recompile JQuery UI files with naming modules like it named in WordPress.

Core doesn't officially support RequireJS. I suggest to have a simple array in your class which maps a jQuery handle to its corresponding file.

I doesn't ask you enable support of RequireJS. I just hate Wordpress for his ugly architecture and "we can't do something because our product piece of shit". Thanks for responding.
