title: How to write angular2 app without node_modules?
body: <p>My server-side web project doesn't use npm at all. Now I need to add a new page that needs more SPA feature. I wish to use the newer Angular2, not the old one.</p>
  
  <p>I miss the way that Angular1 can include only a few js files to start working. I know system.js can do this, but all the samples use <code>npm install</code> to get node_modules. I also want to avoid this big and fat folder.</p>
  
  <p>Can I write angular2 app without node_modules?</p>
