Dropzone is a JavaScript library that turns any HTML element into a dropzone. This means that a user can drag and drop a file onto it, and Dropzone will display file previews and upload progress, and handle the upload for you via XHR.

It's fully configurable, can be styled according to your needs and is trusted by thousands.

Quickstart

Install:

$ npm install dropzone
# or with pnpm:
$ pnpm add dropzone

Use as ES6 module (recommended):

import { Dropzone } from "dropzone";
const dropzone = new Dropzone("div#myId", { url: "/file/post" });

or use as CommonJS module:

const { Dropzone } = require("dropzone");
const dropzone = new Dropzone("div#myId", { url: "/file/post" });

Not using a package manager or bundler?

Use the standalone files like this:

<script src="https://unpkg.com/dropzone@6/dist/dropzone-min.js"></script>
<link rel="stylesheet" href="https://unpkg.com/dropzone@6/dist/dropzone.css" type="text/css" />

<div class="my-dropzone"></div>

<script>
  // Dropzone has been added as a global variable.
  const dropzone = new Dropzone("div.my-dropzone", { url: "/file/post" });
</script>

Repository layout

This is a monorepo. It holds the library, the documentation and the website:

packages/dropzone	the library published to npm as dropzone
apps/docs	the documentation, built with Docusaurus
apps/website	www.dropzone.dev, built with SvelteKit

pnpm install

pnpm build          # the library and the docs
pnpm test           # the library's unit tests
pnpm test:e2e       # the library's browser tests
pnpm dev:docs       # the documentation, locally
pnpm dev:website    # the website, locally

Building the deployable site

The website and the documentation are published together as one GitHub Pages site: the website at the root, the documentation under /docs. One command produces exactly what gets deployed, in _site/:

pnpm build:site

CI runs the same script, so what you get locally is what ships. It builds each half with its own toolchain and combines them, which means there is no manual copying step to remember or get wrong.
