Add Retry middleware

[yordis]

Problem Statement

Reading this article, https://blog.bearer.sh/add-retry-to-api-calls-javascript-node/ Maybe would be a good idea to add a retry middleware

Solution Brainstorm

function fetchRetry(url, options = {}, retries = 3, backoff = 300) {
  /* 1 */
  const retryCodes = [408, 500, 502, 503, 504, 522, 524]
  return fetch(url, options)
    .then(res => {
      if (res.ok) return res.json()

      if (retries > 0 && retryCodes.includes(res.status)) {
        setTimeout(() => {
          /* 2 */
          return fetchRetry(url, options, retries - 1, backoff * 2) /* 3 */
        }, backoff) /* 2 */
      } else {
        throw new Error(res)
      }
    })
    .catch(console.error)
}
