Drag and drop for React with full DOM control.

Currently works on top of HTML5 drag-and-drop API, but is moving towards a swappable implementation. Support for touch events is on the roadmap but not currently implemented.

If your company uses React DnD and would like to speed up its development, consider sponsoring the project. I'm currently doing it in the spare time but I would be happy to work on it part-time. Drop me an email at dan.abramov@me.com. Exciting new features take time.

Philosophy

  • Keep user in full control over rendering;
  • Don't make assumptions about consuming components and their structure;
  • Hide underlying implementation and its quirks;
  • Make 80% easy, 20% possible.

You can also read The Future of Drag and Drop APIs to get an idea of where we're heading.

Live Demo

See it in action! (Source)

Demo contains a variety of things you can implement with this library, including:

  • Reacting to hover and dropping;
  • Dropping files;
  • Dragging a box around with snapping;
  • Drawing a custom drag layer;
  • Making cards sortable.

You can do much more, but these examples will help you get started!

Features

  • Emits zero DOM or CSS of its own;
  • Like original HTML5 API, emphasizes dragging data and not just “draggable views”;
  • Support dropping files using the same API;
  • Lets components register as “drag sources” or “drop targets” for different kinds of data;
  • Lets a single component contain several drag sources and drop targets;
  • Lets you provide a custom drag handle, whether DOM subnode or an image;
  • Takes the best from HTML5 API but hides its many quirks:
    • doesn't require you to preventDefault anything to start working;
    • emits enter and leave as you'd expect instead of doing it for every child node;
    • lets you read drag state from render();
    • consistently fires events even if source DOM node was removed;
  • Includes a helper to preload images for drag thumbnails;
  • Lets you render a custom drag layer if you'd rather draw your own drag preview.

Documentation

SemVer

We plan to follow SemVer after 1.0. Before 1.0, minor version bumps may contain breaking changes. Breaking changes will be documented in the Upgrade Guide.

API Reference

Complete API reference is available here.

Walkthrough

If you don't feel comfortable diving into examples source code just yet, you can start with the walkthrough.

Examples

Have you played with live demo yet? Here's the source code for it.

To try it locally, clone the project and run:

npm install
npm start
open http://localhost:8080/

Examples use ES6 syntax via Babel transpiler. You can still use React DnD in an ES5 codebase, but if you copy code from examples, make sure you translate it to ES5 where needed.

Installation

The library can be used separately (dist/ReactDND.min.js) or with a bundler such as Webpack or Browserify.

npm install --save react-dnd

Future Roadmap

  • Touch support;
  • Support for mouse events instead of HTML5 drag-and-drop events;
  • Dragging multiple items at once.

Thanks

This library is a React port of an API, parts of which were originally written by Andrew Kuznetsov.

A lot of recent progress is due to Nathan Hutchison's contributions and effort.
