retry

Retry fetch with zero dependency.

Usage

const Retry = retry()
const response = await Retry(async () => fetch('https://localhost:8080/api/200'))

Install

pnpm add -D @patoi/retry
npm add -D @patoi/retry
yarn add -D @patoi/retry

Config

type Config = { retries?: number; sleepTime?: number; debug?: boolean }

const Retry = retry({ retries: 2, sleepTime: 500, debug: true })
const response = await Retry(async () => fetch('https://localhost:8080/api/200'))

Defaults:

• retries: 3
• sleepTime: 1000 ms
• debug: false

Description

Retry request if response is an Error (Timeout, Network, etc. - except AbortError) or Response.status is 500 or greater.

Handles AbortError: if request aborted, no more retries, throws AbortError immediately.

See tests for more: examples

Sleep time increases the delay between request: when a request is completed, the delayed start beginning, for example (sleepTime is 1s):

• First request starts at 0s (immediately), delay is 0s
• Second at 1s (delay is 1s)
• Third at 3s (delay is 2s)
• Fourth at 6s (delay is 3s)
• Fifth at 10s (delay is 4s) and so on..
