title: Adding TypeScript to existing create-react-app app
body: <p>I'm having difficulties adding TypeScript to an <strong>already existing</strong> create-react-app application. Previously I've always added it before starting the project, simply by <code>create-react-app my-app --scripts-version=react-scripts-ts</code>, but that doesn't work now. </p>
  
  <p>The only "solution" I found <a href="https://github.com/wmonk/create-react-app-typescript/issues/108" rel="noreferrer">here</a> is: </p>
  
  <ol>
  <li>Create a temporary project with <code>react-scripts-ts</code></li>
  <li>Copy <code>tsconfig.json</code>, <code>tsconfig.test.json</code> 
  , <code>tslint.json</code> from the temporary project src folder to your project's <code>src</code> folder.</li>
  <li>In <code>package.json</code>, change all the references to <code>react-scripts</code> to <code>react-scripts-ts</code> in the scripts section.</li>
  </ol>
  
  <p>This just seems like a weird workaround, and not very efficient. Does anyone know if it's possible to add it in a better way than this? </p>
