title: Npm "scripts": "start" run express and open url
body: <p>I have this start params in <code>package.json</code></p>
  
  <pre><code>"scripts": {
      "start": "node bin/www"
    },
  </code></pre>
  
  <p>It is running my express app when I am typing <code>npm start</code>. </p>
  
  <p>But I want browser opened <code>http://localhost:8081</code> at the same time. How can I say to <code>start</code> to open my local url as well? </p>
  
  <p>like: <code>"start": "node bin/www, http://localhost:8081"</code> </p>
  
  <p>So when I am typing <code>npm satrt</code> it runs my express app and opens the url at the same time.</p>
