Retry Times

Retry a task at most given times.

Deprecation

This package is deprecated to prefer the new retry-func package.

Installation

npm i retry-times --save

Usage

Retry a task directly

const {buildRetry} = require('retry-times')

// a task is any function without argument
const task = async () => {
  ...
}

const retry = buildRetry(3) // or buildRetry({times: 3})
const data = await retry(task)

Wrap a task with retry

const {buildWithRetry} = require('retry-times')

// a task is any function without argument
const task = async () => {
  ...
}

const withRetry = buildWithRetry(3) // or buildWithRetry({times: 3})
const taskWithRetry = withRetry(task)
const data = taskWithRetry()

API

buildRetry

buildRetry(options) => retry(task) => Promise

buildWithRetry

buildWithRetry(options) => withRetry(task) => wrappedTask() => Promise

options

• times - the task will run at most times
