title: Should I install express, node, etc. every time I make a new project?
body: <p>I have a few conceptual questions, as a newbie to AngularJS. I have been working on a project which connects Mongodb with Express and Node.js.</p>
  
  <ol>
  <li><p>If I will be continuing to make projects which combine Mongodb with Express and Node.js, as well as other projects which use AngularJS to build a website, where should I store my installs of express, node.js, etc?</p></li>
  <li><p>Is it the case there will be different dependencies for projects like this, because each project will require a number of different javascript libraries? (If so, I would think it's worth it to install javascript libraries each time I make a new project.)</p></li>
  </ol>
