Install

npm install @leancloud/use-resource

Example

First, create a hook for fetch:

import { createResourceHook } from '@leancloud/use-resource';

async function fetchJSON<T>(...args: Parameters<typeof fetch>) {
  return (await (await fetch(...args)).json()) as T;
}

const useFetch = createResourceHook(fetchJSON);

use useFetch in the Clock component:

const Clock = () => {
  const [data, { error, loading, reload }] = useFetch<{ datetime: string }>([
    "https://worldtimeapi.org/api/timezone/etc/utc"
  ]);
  return (
    <div>
      <p>Current Time:</p>
      <p>
        {loading && "Loading..."}
        {error && error.message}
        {data && data.datetime}
      </p>
      <button onClick={reload}>Reload</button>
    </div>
  );
};
