Readme

Install the package with npm install droplite
There are four basic requirements
const MyComponent = (props) => {
const [items, setItems] = useState(["A", "B", "C", "D"])
// Requirement 1: add unique key
const listItems = items.map(item =><li key={item}>{item}</li>)
// Requirement 2: Implement on new order Handler
const onNewOrder = (draggedItem, dropOntoItem) => {
const newItemOrder = [...items]
const draggedItemIndex = items.indexOf(draggedItem)
newItemOrder.splice(draggedItemIndex, 1)
newItemOrder.splice(items.indexOf(dropOntoItem), 0, items[draggedItemIndex])
setItems(newItemOrder)
}
// Requirement 3: Wrap the list with DragList HOC
// Requirement 4: pass onNewOrder handler as prop

<div>
<DragList onNewOrder={onNewOrder}>
{listItems}
</DragList>
</div>

Droplite depends on the HTML Drag and Drop API.
DragList
component manages internal state of the drag and drop operation.
The key function in DragList
is the dragOverHandler
that takes care of which element is being dragged over that can later be displaced. Once the onDragEndHandler
is triggered, the current dragged element and the one below it (the draggedOver) are passed onto the onNewOrder
handler.
Draggable
is just a wrapper for your custom defined components that injects props and css classes that are required to start managing the drag and drop event listeners.
Support for mobile devices is not considered.
