title: Is there a way to automatically build a dependency in package.json?
body: <p>I use firebaseui, and I need <a href="https://github.com/firebase/firebaseui-web#building-firebaseui" rel="nofollow noreferrer">to build it</a> with french localization because the localized versions are not published to npm. My current <code>package.json</code> looks like this: </p>
  
  <pre><code>"dependencies": {
      "firebaseui": "^3.5.2"
  }
  </code></pre>
  
  <p>Is there a way to change it so that <code>firebaseui</code> is built with <a href="https://github.com/firebase/firebaseui-web#building-firebaseui" rel="nofollow noreferrer"><code>build-js-fr</code></a> parameter on <code>npm install</code>?</p>
