vue-dropzone

A Vue component for file uploads, powered by Dropzone.js. Check out the demo.

Install

// For Vue.js 2.0+
npm install vue2-dropzone@^2.0.0

You'll also need to load either the Material Icon or FontAwesome icon kits depending on which style of icon you'd like.

    <link href="https://fonts.googleapis.com/icon?family=Material+Icons"
      rel="stylesheet">
    <link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet">
