title: How stop after running react-scripts start?
body: <p>I started a React app with
  npm start
  with start defined in package.json:</p>
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>{
    "name": "testreactapp",
    "version": "0.1.0",
    "private": true,
    "dependencies": {
      "react": "^15.6.1",
      "react-dom": "^15.6.1",
      "react-scripts": "1.0.10"
    },
    "scripts": {
      "start": "react-scripts start",
      "build": "react-scripts build",
      "test": "react-scripts test --env=jsdom",
      "eject": "react-scripts eject"
    }
  }</code></pre>
  </div>
  </div>
  </p>
  <p>I want to stop it now, without closing the terminal. How do I do that?</p>
  <p>Tried:
  npm stop testrectapp
  but that throws error that it needs a script</p>
  <p>Then tried:
  npm run stop with script &quot;stop&quot;: &quot;pkill --signal SIGINT testreactapp&quot;
  that throws error 'pkill is not recognized as a command'</p>
