Simple module extending javascript Promise with retry strategy

Synopsis

import RetryPromise from '@twake/retry-promise'

const promise = new RetryPromise((resolve, reject) => {
  fetch(URL)
    .then(val => resolve())
    .catch(reject)
})

const promiseWithOption = new RetryPromise((resolve, reject) => {
  fetch(URL)
    .then(val => resolve())
    .catch(reject)
  },{
    retries: 6
    minTimeout: 10 // The number of milliseconds before starting the first retry
    maxTimeout: 100 // The maximum number of milliseconds between two retries
  }
)

const allPromises = RetryPromise.all([
      new RetryPromise((resolve, reject) => {
        fetch(URL_1)
          .then(val => resolve())
          .catch(reject)
      }), 
      new RetryPromise((resolve, reject) => {
        fetch(URL_2)
          .then(val => resolve())
          .catch(reject)
      })
    ])

const allSettledtPromises = RetryPromise.allSettled([
      new RetryPromise((resolve, reject) => {
        fetch(URL_1)
          .then(val => resolve())
          .catch(reject)
      }), 
      new RetryPromise((resolve, reject) => {
        fetch(URL_2)
          .then(val => resolve())
          .catch(reject)
      })
    ])

How it works

RetryPromise allows to build promises that can be re-triggered 3 times or a custom number of times. We can also redefine minTimeout option and maxTimeout option values, by default it is 100 ms and 1000 ms. Finally, all and allSettled are very similar to the native Promise methods, but they do not accept Promises instances as parameters.
