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">

Usage

1. Import the module
2. Register it as a component as you would any other Vue component
3. Use it within your template

Example

<template>
  <div id="app">
    <p>Welcome to your Vue.js app!</p>

    <dropzone id="myVueDropzone" url="https://httpbin.org/post" v-on:vdropzone-success="showSuccess">
        <!-- Optional parameters if any! -->
        <input type="hidden" name="token" value="xxx">
    </dropzone>

  </div>
</template>

Then from your parent Vue instance, you can call the methods by using the following:

vm.$refs.myUniqueID.processQueue()
//vm refers to your current instance
