useAsync

React hook that resolves an async function or a function that returns a promise;

Usage

// Returns a Promise that resolves after one second.
const fn = () => new Promise((resolve) => {
  setTimeout(() => {
    resolve('RESOLVED');
  }, 1000);
});

const Demo = () => {
  const state = useAsync(fn);

  return (
    <div>
      {state.loading?
        <div>Loading...</div>
        : state.error?
        <div>Error...</div>
        : <div>Value: {state.value}</div>
      }

  );
