How to add color-picker to laravel 5 app?

In my laravel 5.7 / jquery 3.4.1 I want to add color-picker from https://github.com/narsenico/a-color-picker and in my edit.blade.php file I add link to color-picker files and js file which is related to this editor after color-picker files :

@section('scripts')

    <link rel="stylesheet" href="" type="text/css">
    <script src=""></script>

    <script src="?dt="></script>

    <script src=""></script>
    {!! JsValidator::formRequest('App\Http\Requests\ColorRequest', '#form_color_edit'); !!}


    <script>
        /*<![CDATA[*/

        var backendColor = new backendColor('edit',  // must be called before jQuery(document).ready(function ($) {
            <?php echo $appParamsForJSArray ?>
        );
        jQuery(document).ready(function ($) {
            backendColor.onBackendPageInit('edit')
        });

        /*]]>*/
    </script>

@endsection

and in color.js I try to init color-picker as :

var this_backend_home_url
var this_id
var this_csrf_token

function backendColor(page, paramsArray) {  // constructor of backend Color's editor - set all from referring page and from server
    // alert( "backendColor  paramsArray::"+var_dump(paramsArray) )
    this_backend_home_url = paramsArray.backend_home_url;
    this_backendLengthMenuArray = paramsArray.backendLengthMenuArray;
    this_csrf_token = paramsArray.csrf_token;

    if (page == "edit") {
        this_id = paramsArray.id;
    }
    if (page == "list") {
        this.ColorsLoad()
        $(".dataTables_filter").css("display", "none")
        $(".dataTables_info").css("display", "none")
    }
} // function backendColor(Params) {  constructor of backend Color's editor - set all from referring page and from server


backendColor.prototype.onBackendPageInit = function (page) {  // all vars/objects init
    backendInit()
    const AColorPicker = require('a-color-picker'); // I GOT JS errors (Below) !
    AColorPicker.from('color-picker');

} // backendColor.prototype.onBackendPageInit= function(page) {
...

But I got JS errors:
