    I'm unable to successfully follow the Getting Started with Kendo UI Wrappers for React guide. When I follow Microsoft's TypeScript-React-Starter guide using the standard create-react-app but with react-scripts-ts instead I receive typescript compiler errors from the kendo dependencies.

    The first is the unused kendo module.

    error TS6133: 'kendo' is declared but its value is never read.


    If I add a workaround for that by adding an if (kendo) {} I get the following error

    error TS2306: File 'node_modules/@progress/kendo-ui/index.d.ts' is not a module error

    FYI with guidance on the kendo getting started tutorial I had this line:

    import * as kendo from '@progress/kendo-ui';

    which produced an error. But after reviewing the react webinar it led me to this working import instead.

    import '@progress/kendo-ui';

    Hello, Ryan,

    Indeed, the Kendo main library can be imported using different approaches.

    It can also be required:


    Or to be directly added as a standard script reference if an index.ejs or index.html is used.

    We will update these options in the documentation, so issues like this one are easy to locate and fix.

    I also, updated your Telerik points for bringing this to our attention.

    I am unable to use kendo react grid component in my typescript based react project.

    Simplest of implementation throws the same error persistantly.
    Says: ./src/components/about/AboutPage.tsx
    Cannot find file: 'main.js' does not match the corresponding name on disk: '.\node_modules\@Progress\kendo-react-grid\dist\es\@progress'.




    All I tried doing is this based on an example from here:


    import React from "react";<br>import { Grid, GridColumn as Column } from '@Progress/kendo-react-grid';<br>import products from '../../../tools/products.json';<br><br>const AboutPage = () => {<br>    const localGridState = {<br>        data: [<br>            { field1: 'a', field2: 'b' },<br>            { field1: 'c', field2: 'd' }<br>        ]<br>    }<br>    return (<br>        <div><br>            <h2>About</h2><br>            <p><br>                This app uses React, Redux, React Router, and many other helpful<br>                libraries.<br>        </p><br><br>            <Grid data={}></Grid><br>        </div><br>    );<br>}<br>export default AboutPage;

    But the same implementation works well on a react JS implementation. 
    Please do suggest any changes to resolve this error. 
    Should we even consider going away from kendo UI libraries for react.
