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 (import Dropzone from 'vue2-dropzone')
  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>

<script>
  import Dropzone from 'vue2-dropzone'

  export default {
    name: 'MainApp',
    components: {
      Dropzone
    },
    methods: {
      'showSuccess': function (file) {
        console.log('A file was successfully uploaded')
      }
    }
  }
</script>

Props

Many of these props are inherited from dropzone configuration so see their doco for further details.

Important : - If you are using following options as props (attributes) to component then use dash-seperated names of props. E.g. paramName becomes :param-name="", showRemoveLink becomes :show-remove-link="". - If you are passing props using dropzoneOptions object then, use prop names same as given in below table. E.g. :dropzone-options="customOptionsObject". customOptionsObject is defined in data() with following props names.
