Minor Changes

• #518 6310227 Thanks @clauderic! - Major internal refactor of measuring and collision detection.

  Summary of changes

  Previously, all collision detection algorithms were relative to the top and left points of the document. While this approach worked in most situations, it broke down in a number of different use-cases, such as fixed position droppable containers and trying to drag between containers that had different scroll positions.

  This new approach changes the frame of comparison to be relative to the viewport. This is a major breaking change, and will need to be released under a new major version bump.

  Breaking changes:

  • By default, @dnd-kit now ignores only the transforms applied to the draggable / droppable node itself, but considers all the transforms applied to its ancestors. This should provide the right balance of flexibility for most consumers.
    • Transforms applied to the droppable and draggable nodes are ignored by default, because the recommended approach for moving items on the screen is to use the transform property, which can interfere with the calculation of collisions.
    • Consumers can choose an alternate approach that does consider transforms for specific use-cases if needed by configuring the measuring prop of . Refer to the example.
  • Reduced the number of concepts related to measuring from ViewRect, LayoutRect to just a single concept of ClientRect.
    • The ClientRect interface no longer holds the offsetTop and offsetLeft properties. For most use-cases, you can replace offsetTop with top and offsetLeft with left.
    • Replaced the following exports from the @dnd-kit/core package with getClientRect:
      • getBoundingClientRect
      • getViewRect
      • getLayoutRect
      • getViewportLayoutRect
  • Removed translatedRect from the SensorContext interface. Replace usage with collisionRect.
  • Removed activeNodeClientRect on the DndContext interface. Replace with activeNodeRect.

• 528c67e Thanks @clauderic! - Introduced the useLatestValue hook, which returns a ref that holds the latest value of a given argument. Optionally, the second argument can be used to customize the dependencies passed to the effect.

Patch Changes

• #561 02edd26 Thanks @clauderic! - - The useNodeRef hook's onChange argument now receives both the current node and the previous node that were attached to the ref.
  • The onChange argument is only called if the previous node differs from the current node
