vue-auto-dropzone

A Dropzone.js component for Vue.
Typescript support, native slots, and more.

Installation

yarn install vue-auto-dropzone

Basic usage

<template>
    <vue-auto-dropzone ref="dz" :options="options" />
</template>
<script lang="ts">
    import Vue from 'vue';
 
    import VueAutoDropzone from 'vue-auto-dropzone';
 
    export default Vue.extend({
        components: {
            VueAutoDropzone,
        },
        data() {
            return {
                options: {
                    url: 'https://httpbin.org/anything',
                },
            };
        },
        mounted() {
            // The Dropzone instance is available after mounting
            const dz = this.$refs.dz;
        }
    });
</script> 

Slots

All content is configurable by slots.
Slots receive the instance itself as their scope, meaning all relevant fields are directly accessible.
To omit default styling on the slot, also specify :include-styling="false".

<vue-auto-dropzone :options="options" :include-styling="false" v-slot="{ files, removeFile }">
    <p v-if="!files.length">Give me fuel, give me files</p>
 
    <figure v-for="file in files" :key="file.upload.uuid" @click="removeFile(file)">
        <img v-if="file.dataURL" :src="file.dataURL" :alt="file.name" />
        <figcaption>
            {{file.name}}
            <span v-if="file.upload.progress !== 100">{{ file.upload.progress.toFixed(0) }}%</span>
        </figcaption>
    </figure>
</vue-auto-dropzone>
