title: Automatic run gulp tasks via npm
body: <p>I usually run gulp via npm, e.g. in my package.json</p>
  
  <pre><code>"scripts": {
      "test": "gulp test",
      "minify": "gulp minify"
  }
  </code></pre>
  
  <p>Then I can run command such as</p>
  
  <pre><code>npm run minify
  </code></pre>
  
  <p>Which is okay, but every time I've new tasks in my gulpfile, I need to add them to the package.json under the scripts section, is there any better way to do so?</p>
  
  <p><strong>Reason</strong>: I only install npm globally to my <code>path</code> so all other modules will not pollute my <code>path</code>, so I need to run them via <code>npm</code> scripts</p>
