attemptify

TypeScript retry library.

Objective

The aim of this module is to simplify the setup and execution of retries. When setting up a retry, there are a number of considerations, such as how long to wait, how many attempts to make, and whether to fail. This module provides a unified procedure for setting up and executing these complicated retries.

Usage

About retry policies

This module provides some retry policies - the policy is the strategy for retry.

Getting started

Try to start from SimpleRetryPolicy to call ofDefaults and boot Attempt with that policy.

const simpleRetry = SimpleRetryPolicy.ofDefaults();

new Attempt(simpleRetry).execute(() => (new Application().run()));

This retry policy has settings that wait for 1 seconds in interval and max attempt count is 5 times. Attempt can execute synchronous or asynchronous, and when asynchronously want to attempt, it is possible to call executeAsync like below:

new Attempt(simpleRetry).executeAsync(() => (new Application().run()));
