Explicit error handling, timeoutable `fetch()`

// Inspired by davej's gist:  https://gist.github.com/davej/728b20518632d97eef1e5a13bf0d05c7

// Accepts same arguments as `fetch()`, then returns a promise
//   - Reject if response is not ok (4xx, 5xx)
//   - Reject if timeout (by default, a fetch won't timeout)
const enhancedFetch = (...args) => {
  const whinyFetch = fetch(...args)
    .then((response) => {
      if (response.ok) {
        return response
      }
      throw new Error('Response was not ok')
    })

  return Promise.race([
    whinyFetch,
    new Promise((_, reject) => {
      setTimeout(() => reject(new Error('Fetch Timeout')), 7000)
    })
