title: Node: difference between project and package
body: <p>I understand the <a href="https://stackoverflow.com/q/20008442/5353461">difference between a module and a package</a>, but what is difference between a project and a package in Node.js?</p>
  
  <p>It seems every project needs a <code>package.json</code> file, implying every project is a package... is every package a project as well?</p>
