title: Adding components to default vue-cli webpack app
body: <p>For the sake of reproducibility: First, I created a default project using vue-cli like so:</p>
  
  <pre><code>npm install -g vue-cli
  vue init webpack spa
  cd spa
  npm install
  npm run dev
  </code></pre>
  
  <p>From there I decided to start by replacing the Vue logo with an app-header component. I wrote the code like so:</p>
  
  <p><a href="https://i.stack.imgur.com/3aQYz.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/3aQYz.png" alt="enter image description here"></a></p>
  
  <p>I first created AppHeader.vue in the components folder and gave it a template, export script, and empty style for good measure. It has an element (I've tried with and without it). I imported the AppHeader component in App.vue and used it in the template.</p>
  
  <p>It doesn't show up. The only thing I see is the HelloWorld component in the router-view.</p>
  
  <p>I think I covered all my bases, but does anyone see something I missed?</p>
