title: What is node-libs-browser and why is it being installed when I install babel-loader
body: <p>I have just installed <a href="https://github.com/babel/babel-loader" rel="noreferrer">babel loader</a>, to use babel with webpack.</p>
  
  <p>It brings in 3 additional node dependencies, however only 2 of these I expected </p>
  
  <p>from the babel loader <a href="https://github.com/babel/babel-loader/blob/master/package.json" rel="noreferrer">package.json</a></p>
  
  <pre><code>"peerDependencies": {
    "babel-core": "*",
    "webpack": "*"
  },
  </code></pre>
  
  <p>So why am I also getting <strong>node-libs-browser</strong> I don't know what it is, and don't want the extra module in my devDependencies</p>
