A lightweight wrapper to use fetch more efficiently and easily and with better error handling, and this is promisified!

Basic usage:
import from CDN

<script type="text/javascript" src="https://unpkg.com/[email protected]"></script>

Or from NPM,

import fetch from 'fetch-req';

const someFunction = async ()=> {
  const respGET = await fetch.get('http://dummy.restapiexample.com/api/v1/employees');
  const respPOST = await fetch.post('http://dummy.restapiexample.com/api/v1/employees', { 'dummyData': 'Mukesh'});
}

Additional methods:
1. Poll - call an endpoint and handle response in interval.

const endpoint = () => fetch.get('http://dummy.restapiexample.com/api/v1/employees');

const poll = fetch.poll(endpoint, callback, 1000);
poll.pause();                // Pause polling
poll.resume();               // Resume polling
poll.updateInterval(1000);  // Update the interval, set it to 1000ms

Note: This doesn't use setInterval, and it prevents the race conditions because, it makes the next call exactly after given time(in ms) from the time last response received.

2. Retry - Retry no of times in case request fails.

const resp = await fetch.retry(3).get('http://dummy.restapiexample.com/api/v1/employees');
