Vue Frontend

[royalwood]

I tried to customize Vue.js based frontend on this project.

But when I wrote some code in app.js, error raised.

var Vue = require('vue');
var FileUpload = require('vue-upload-component');

Then chrome browser shows error like as follows:

Uncaught ReferenceError: require is not defined
    at app.js:25

How can I solve this problem?
