Now it's time to add the Vue.js library to our project. Vue was downloaded as part of our NPM install, so now we can simply link to the browser-build of Vue.js with a script tag.
index.html:
<body> <div id="toolbar">...</div> <div id="app">...</div> <script src="node_modules/vue/dist/vue.js"></script> <script src="app.js"></script> </body>
It's important that we include the Vue library before our own custom app.js script, as scripts run sequentially.
Vue will now be registered as a global object. We can test this by going to our browser and typing the following in the JavaScript console:
console.log(Vue);
Here is the result:
