Usage

Simple Usage

TypeScript

for sync

import Action from 'async-retry.ts'

const action = () => {}
const handlers = [
  {
    error: 'error1',
    handler: yourHandler1,
  },
  {
    error: 'error2',
    handler: yourHandler2,
  },
]

Action.retry(action, 3, handlers)

for async

import Action from 'async-retry.ts'

const action = async()=>{}
const handlers = [{
  error: 'error1',
  handler: async yourHandler1()=>{}
}, {
  error: 'error2',
  handler: async yourHandler2()=>{}
}]

await Action.retryAsync(action, 3, handlers)

JavaScript

for sync

const Action = require('async-retry.ts').default

const action = () => {}
const handlers = [
  {
    error: 'error1',
    handler: yourHandler1,
  },
  {
    error: 'error2',
    handler: yourHandler2,
  },
]

Action.retry(action, 3, handlers)

for async

const Action =require('async-retry.ts').default

const action = async()=>{}
const handlers = [{
  error: 'error1',
  handler: async yourHandler1()=>{}
}, {
  error: 'error2',
  handler: async yourHandler2()=>{}
}]

await Action.retryAsync(action, 3, handlers)

An example of retrying with delay

Add delay logic in your error handlers, like so

import Action from 'async-retry.ts'

const action = async()=>{}
const handlers = [{
  error: 'error1',
  handler: async yourHandler1()=>{
    await new Promise(resolve => setTimeout(resolve, 1000))
    // handling
  }
}, {
  error: 'error2',
  handler: async yourHandler2()=>{
    await new Promise(resolve => setTimeout(resolve, 1000))
    // handling...
  }
}]

await Action.retryAsync(action, 3, handlers)
