title: How to make an angular application take arguments from command line?
body: <p>I have an AngularJS application in which my code looks something like this:</p>
  
  <pre><code>myApp = angular.module('myApp',
    [
      'ui.router',
      'ngMaterial',
      'ngMessages'
    ]
  );
  
  myApp.constant('CONSTANTS', (function() {
    // Define your variable
    return {
      backend: {
        baseURL: 'http://mybackend.com:3026'
      }
    };
  })());
  </code></pre>
  
  <p>I run this application using <a href="https://www.npmjs.com/package/http-server" rel="noreferrer">http-server</a> on port number 8000 like this:</p>
  
  <pre><code>% http-server -p 8000
  </code></pre>
  
  <p>I want to pass in a command-line argument for the <code>backend.baseURL</code> such that it over-rides the value specified in the code. How can I do it??</p>
