FocusManager

FocusManager is a module that exports a selection of helpful utility functions to be used in conjunction with the ref from a React Scope, such as TabbableScope.

Example

import {
  focusFirst,
  focusNext,
  focusPrevious,
  getNextScope,
  getPreviousScope,
} from 'react-interactions/accessibility/focus-manager';

function KeyboardFocusMover(props) {
  const scopeRef = useRef(null);

  useEffect(() => {
    const scope = scopeRef.current;

    if (scope) {
      // Focus the first tabbable DOM node in my children
      focusFirst(scope);
      // Then focus the next chilkd
      focusNext(scope);
    }
  });
  
  return (
    <TabbableScope ref={scopeRef}>
      {props.children}
    </TabbableScope>
  );
}
