title: Vue-cli with node
body: <p>I'm a little bit confused about using Vue and node simultaneously.  You can run a Vue-cli application locally by typing <code>npm run dev</code> and it runs on one port, and then I also created an express server file with some routes and that runs on another port.  Everything works fine...</p>
  
  <p>But why does Vue-cli have to "run" as if its a server, when it's just client-side code?  Does this mean in production I really have to be occupying two ports at the same time for one app?</p>
