using React component library without @types
<p>I'm developing React with TypeScript</p>

<p>What I want to do is to use React component library without @types definition.</p>

<p>I'd like to use this library<br>
<a href="https://github.com/react-component/calendar" rel="noreferrer">https://github.com/react-component/calendar</a></p>

<p>In my React code, I wrote as below</p>

<pre><code>import * as React from "react";
import * as ReactDOM from "react-dom";
import Calendar from 'rc-calendar';

ReactDOM.render(&lt;Calendar /&gt;, document.getElementById('content'));
</code></pre>

<p>but I get error: </p>

<pre><code>ERROR in ./index.tsx
(4,22): error TS2307: Cannot find module 'rc-calendar'.
</code></pre>

<p>I'm guessing this is because there is no type definition but the library above seems not have type definition file for typescript.<br>
How could I use such library with TypeScript?</p>
