@collapsed/react@4.0.1

Major Changes

• 5e427ec: This is a big refactor of react-collapsed, enough I wanted to denote it with a new major version.

  BREAKING CHANGES

  • expandStyles and collapseStyles options have been removed.

  • onExpandStart, onExpandEnd, onCollapseStart, onCollapseEnd options have been removed and replaced with onTransitionStateChange:

    const useCollapse({
      onTransitionStateChange(stage) {
        switch (stage) {
          case 'expandStart':
          case 'expandEnd':
          case 'expanding':
          case 'collapseStart':
          case 'collapseEnd':
          case 'collapsing':
            // do thing
          default:
            break;
        }
      }
    })

  Other changes

  • Unique IDs for accessibility are now generated with React.useId if it's available.
  • Styles assigned to the collapse element are now assigned to the DOM element directly via a ref, and no longer require ReactDOM.flushSync to update styles in transition.
  • Added role="region" to collapse.
  • Added logic to handle disabling the animation if the user has the prefers reduced motion setting enabled.
  • Replaced animation resolution handling to a programmatic timer, instead of the 'transitionend' event. Should fix #103.
  • Improved the types for getCollapseProps and getToggleProps, so their arguments and return type is more accurately typed. This should help catch cases when props returned by the getters are duplicated on the component (such as ref or style).
  • Changes the props returned by getToggleProps depending on the HTML tag of the component.
