    Hi there,

    I'm trying to run Kendo Editor on React using the sample that appears on NPM.

    I'm using webpack.

    This is my component:

    var KendoEditor = require('kendo-ui-react-jquery-editor').default;
    //Don't forget CSS, webpack used to include CSS
    var Example = React.createClass({
        render: function() {
            return (
              <KendoEditor options={{height: 550,sortable: true}}>
    module.exports = Example;

    This is my view

    @Html.React("Client.Example", new { }, clientOnly: true)


    And I'm already bundling kendo.editor.js and kendo.all.js.

    The error that appears is:

    Uncaught TypeError: Cannot read property 'Editor' of undefined

    On this line:

    //note I am not using jQuery plugin to instantiate, don't want to wait for namespace on $.fn
        this.widgetInstance=new _kendoEditor2['default'].ui.Editor(elementNode,this.props.options);//if props are avaliable for events, triggers, unbind events, or methods make it happen now


    Can you please help? Thanks in advance.

    Hello guzman,

    Please note that this project is a community effort and is not officially supported. The following reply is a general debugging advice, and any problems in the package should be addressed to the project maintainer.

    Since the error occurs on the line this.widgetInstance=new _kendoEditor2['default'].ui.Editor, it means that the .ui part is undefined. The line of code is found in the editor npm package. The imported part (_kendoEditor2['default']) is in this import, so it is likely that the npm plug-in cannot find the proper Kendo UI files.

    The files should not be required at the top level, like in the posted snippet:


    Rather, the npm package should load it itself.
