title: Sequential NPM script after "react-scripts start"
body: <p>Working on an Electron app with React. Right now, to get things started, I run the typical <code>npm start</code> command which runs the <code>react-scripts start</code> script.</p>
  <p>This starts the dev server. Once the dev server is started, I open a second terminal window and run a script to start electron <code>npm run start-electron</code> which opens my React app in the Electron window.</p>
  <p>This works as expected, but I was curious if there was a way to create a script that would:</p>
  <ul>
  <li>Start the dev server</li>
  <li>Wait for dev server to be started</li>
  <li>Then start electron</li>
  </ul>
  <p>I tried setting up a sequential script in package.json but it only starts up the dev server. For example <code>npm run start &amp;&amp; npm run start-electron</code>.</p>
  <p>This isn't make or break. The two terminal option works fine, just didn't know if this was possible.</p>
