title: Passing command line arguments to webpack.config.js
body: <p>I have a simple webpack.config.js </p>
  
  <pre><code>module.exports = {
    entry: "./app.js",
    output: {
      filename: "bundle.js"
    },
  }
  </code></pre>
  
  <p>And I want to pass the values for <code>entry</code>and <code>output</code> through command line arguments. Is that possible and how would I do that? </p>
