async-rerun/lib/runner.min.js

Perfect light-weight & asynchronious package for asynchroniously retry/rerun of any logic...

/**
 * @param {Function} fn The function which will be used as parameter should return a PROMISE & SHOULD NOT HAVE ANY PARAMETER it's compulsory, as its a async retry mechanism.
 * @param {Number} maxRetries Max Retries in number.
 * @param {Number} delayInMS Delay time for retries in number as mili-seconds(ms).
 * @param {Boolean} alwaysRetry To retry always untill the positive response, If its true then maxRetries will not count.
 * @param {Boolean} showLogs To show logs for all retries.
