# `@parzh/retryable` Convenience function to retry executing an action, until a desired result is achieved ## Installation ``` npm i @parzh/retryable ``` ``` yarn add @parzh/retryable ``` ## Usage ```js const content = await retryable((resolve, reject, retry) => { fs.readfile("/path/to/file", (err, data) => { if (!err) // no errors occured return resolve(data); // here: an error occured if (retry.count >= RETRY_LIMIT) if (SHOULD_IGNORE_RETRY_LIMIT) // retry limit reached, but ignored retry.setCount(0); else // retry limit reached return reject("Retry limit reached!"); // here: retry limit is ignored or not reached if (SHOULD_RETRY_IMMEDIATELY) // retrying immediately retry(); else // retrying after exponential backoff (see https://en.wikipedia.org/wiki/Exponential_backoff) retry.after("exponential"); // same as: retry.after(2 ** retry.count * 100); }); }); ```
