node-fetch-retry-callback

node-fetch-retry-callback is a wrapper library that add retry over node-fetch.

How to install?

npm i --save node-fetch-retry-callback

How to use?

The following code shows an example that does not have retry:

const fetch = require('node-fetch');
let res = await fetch('https://google.com', { method: 'GET' })

The code down bellow shows how node-fetch-retry-callback works:

const fetch = require('node-fetch-retry-callback');
let res = await fetch('https://google.com', { method: 'GET', retry: 3 })

A pause (in milliseconds) can be added between retry attempts using the pause option. Pause values < 0 are treated as 0.

The following example waits 1 seconds (1000 ms) between retry attempts.

const fetch = require('node-fetch-retry');
let res = await fetch('https://google.com', { method: 'GET', retry: 3, pause: 1000 })

If you want to add callback that will be called between the retries. The callback is invoked BEFORE any (optional) pauses.

let opts = {
    method: 'GET', 
    retry: 3,
    callback: retry => { console.log(`Trying: ${retry}`) }
}

const fetch = require('node-fetch-retry');
let res = await fetch('https://google.com', opts)

If you would like to silence pause messages in your console include a silent boolean in your options.

let opts = {
    method: 'GET',
    retry: 3,
    pause: 1000,
    silent: true
}
