Package Exports

cross-web-components

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (cross-web-components) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

EventHandler

import { EventHandler } from 'cross-web-components';

const customEvent = EventHandler.channel('[CUSTOM_CHANNEL]');

Example - Dispatch (React)

export const Example = () => {
  const customEvent = EventHandler.channel('[MODAL]');

  const [id, setId] = useState<string>('');

  const onClick = () => customEvent.dispatch<ModalState>('[MODAL_UPDATE_STATE]', { state: true, id });

  return (
    <>
      <input placeholder='id' value={id} onChange={({ target: { value } }) => setId(value)} />
      <button onClick={onClick}>Show</button>
    </>
  );
};

Example - Listener (React)

export const Modal = () => {
  const customEvent = EventHandler.channel('[MODAL]');

  const [state, setState] = useState<ModalState>({ state: false, id: '' });

  useEffect(() => {
    const listener = customEvent.listener<ModalState>('[MODAL_UPDATE_STATE]', payload => setState(payload));
    return () => {
      listener.unsubscribe();
    };
  }, []);

  const onClick = () => setState({ id: '', state: false });

  return (
    <>
      {state.state && (
        <div>
          <h1>{state.id}</h1>
          <button onClick={onClick}>Hide</button>
        </div>
