help React DnD FAQ
Does React DnD work with the latest React 18 strict mode?
Yes, React DnD has been updated over the years to ensure compatibility with modern functional components and React Hooks. Using the useDrag and useDrop hooks makes it much easier to implement drag-and-drop functionality within React 18's strict mode compared to older class-based implementations.
Does React DnD support touch devices out of the box?
By default, React DnD utilizes the HTML5 drag-and-drop API, which does not provide native support for touch screens. To make your interface work on mobile phones or tablets, you must install and apply a custom backend, such as the react-dnd-touch-backend library.
How does React DnD handle the state of dragged items?
React DnD acts as a state management layer using a context provider called DndProvider. When an item is dragged, it passes a monitor object to your hooks, allowing you to update your component's state based on whether the item is currently being dragged or dropped.
Do I need an external library like Redux to use React DnD?
No, React DnD is self-contained and does not require third-party utility libraries like Redux to function. However, complex implementations might use such libraries alongside React DnD to handle deep array manipulation when reordering list items on drop.
