Load different component depending on result of promise

import useLazyComponent from 'use-lazy-component';

const SomeComponent = () => {
  const { component: Component, loading, error } = useLazyComponent<BigComponent>(
    async () => {
      const result = await someAsyncFunction();

        return import('./bigComponent');
      }
      return import('./defaultComponent');
