Codeship Status for enyo/dropzone

Dropzone.js is a light weight JavaScript library that turns an HTML element into a dropzone. This means that a user can drag and drop a file onto it, and the file gets uploaded to the server via AJAX.

If you want support, please use stackoverflow with the dropzone.js tag and not the GitHub issues tracker. Only post an issue here if you think you discovered a bug or have a feature request.

Please read the contributing guidelines before you start working on Dropzone!

>> Download <<

Starting with version 2.0.0 this library does no longer depend on jQuery (but it still works as a jQuery module).

Dropzone is compatible with component, there's a standalone version and an AMD module that's compatible with RequireJS in the downloads folder.


Main features

  • Image thumbnail previews. Simply register the callback thumbnail(file, data) and display the image wherever you like
  • Retina enabled
  • Multiple files and synchronous uploads
  • Progress updates
  • Support for large files
  • Complete theming. The look and feel of Dropzone is just the default theme. You can define everything yourself by overwriting the default event listeners.
  • Well tested


For the full documentation and installation please visit www.dropzonejs.com

Please also refer to the FAQ.


For examples, please see the GitHub wiki.


Implicit creation:

<form id="my-awesome-dropzone" action="/target" class="dropzone"></form>

That's it. Really!

Dropzone will automatically attach to it, and handle file drops.

Want more control? You can configure dropzones like this:

// "myAwesomeDropzone" is the camelized version of the ID of your HTML element
Dropzone.options.myAwesomeDropzone = { maxFilesize: 1 };

...or instantiate dropzone manually like this:

new Dropzone("div#my-dropzone", { /* options */ });

Note that dropzones don't have to be forms. But if you choose another element you have to pass the url parameter in the options.

For configuration options please look at the documentation on the website or at the source.

Register for events

If you want to register to some event you can do so on the dropzone object itself:

  init: function() {
    this.on("error", function(file, message) { alert(message); });
// or if you need to access a Dropzone somewhere else:
var myDropzone = Dropzone.forElement("div#my-dropzone");
myDropzone.on("error", function(file, message) { alert(message); });

For a list of all events, please look at the chapter »Events« in the documentation or at the source.

Browser support

  • Chrome 7+
  • Firefox 4+
  • IE 10+
  • Opera 12+ (Version 12 for MacOS is disabled because their API is buggy)
  • Safari 6+

For all the other browsers, dropzone provides an oldschool file input fallback.

Why another library?

I realize that there are already other libraries out there but the reason I decided to write my own are the following:

  • I didn't want it to be too big, and to cumbersome to dive into.
  • I want to design my own elements. I only want to register callbacks so I can update my elements accordingly.
  • Big files should get uploaded without a problem.
  • I wanted a callback for image previews, that don't kill the browser if too many too big images are viewed.
  • I want to use the latest API of browsers. I don't care if it falls back to the normal upload form if the browser is too old.
  • I don't think that it's necessary anymore to depend on libraries such as jQuery (especially when providing functionality that isn't available in old browsers anyway).
