dnd-core [Legacy Repo]
** NOTE: React-Dnd has been restructured as a monorepo. This code has been merged into the the react-dnd main repository.
Drag and drop sans the GUI.
This is a clean implementation of drag and drop primitives that does not depend on the browser. It powers React DnD internally.
To give you a better idea:
- There is no DOM here
- We let you define drop target and drag source logic
- We let you supply custom underlying implementations (console, DOM via jQuery, React, React Native, whatever)
- We manage drag source and drop target interaction
This was written to support some rather complicated scenarios that were too hard to implement in React DnD due to its current architecture:
- Mocking drag and drop interaction in tests
- Full support for arbitrary nesting and handling drag sources and drop targets
- Dragging multiple items at once
- Even when source is removed, letting another drag source “represent it” (e.g. card disappeared from one Kanban list, reappeared in another one)
As it turns out, these problems are much easier to solve when DOM is thrown out of the window.
What's the API like?
Tests should give you some idea. You register drag sources and drop targets, hook up a backend (you can use barebone
TestBackend or implement a fancy real one yourself), and your drag sources and drop targets magically begin to interact.
