title: Adding the Intro.JS library to a Vue-Cli / Webpack project
body: <p>I'm building my first project using <strong>vue-cli</strong> and <strong>webpack</strong> and I'm not sure how to properly use an external JavaScript library to my project.  </p>
  
  <p>I want to add the <strong>Intro.js</strong> library which simply requires me to import the <strong>intro.js</strong>, add some tags to some HTML elements, and call the <strong>introJs().start()</strong> function.</p>
  
  <p>I've installed the library with <code>npm install introj.js --save</code></p>
  
  <p>I've imported the library by adding <code>import introJS from 'intro.js'</code> into my <code>&lt;script&gt;</code> section of my <code>App.vue</code> file.</p>
  
  <p>I've checked the compiled <code>app.js</code> file and I know introJS is being compiled so everything is good there.</p>
  
  <p>My question is, where do I put <code>introJs().start()</code>?  I tried putting it in the <code>mounted()</code> function of the <code>App.vue</code> file but that doesn't work.</p>
  
  <p>Additional Info:  When I try to run <code>introJS().start()</code> from the <code>mounted ()</code> method in <code>App.vue</code> I receive this error: <code>Error in mounted hook: "TypeError: __WEBPACK_IMPORTED_MODULE_7_intro_js___default(...) is not a function"</code></p>
