Wraps a promise so that it can be retried

Usage

const asRetryablePromise = require("as-retryable-promise");
const fs = require("fs");

  fs.readFile("./my-file.txt", (err, data) => {
    if (err) return reject(err);
    return resolve(data);
  });
});

// Will retry if the file is locked
const options = {
  maxRetries: 5,
  timeout: 1000,
  retryCondition: error => error.code === "EACCES",
};
const retryable = asRetryablePromise(fn, options);

retryable
  .then(data => console.log(data))
  .catch(err => console.error(err)); // Will return the error from the last attempt
