title: How to edit a node module installed via npm?
body: <p>I'm using the node_swiz module, which in turn uses the validator module.</p>
  
  <p>I want to make changes to the validator module, but I used npm install to install the modules/dependencies. </p>
  
  <p>Can I just make changes to the validator module inside of node_modules, or will that node_modules dependencies be re-created and the latest version gotten when I publish to heroku or next time I run npm install?</p>
  
  <p>The structure looks like this:</p>
  
  <pre><code>myNodeApplication
    - node_modules
       - swiz
           - node_modules
              - validator [this is the library I want to edit]
  </code></pre>
  
  <p>Thanks for the help!</p>
