The @brillout/fetch package uses:

• The browser built-in window.fetch if run in the browser.
• The NPM package node-fetch if run in Node.js.

@brillout/fetch is designed to work well with bundlers such as Webpack and Parcel.

No polyfill is used in the browser, saving KBs and delay for your users. This is means that IE11 is not supported. (IE11 is the only browser not supporting fetch: https://caniuse.com/#feat=fetch.) With IE11's decline, not supporting IE11 is more and more an option. If you want IE11 support then use another fetch library, see the list of fetch libraries below.

const fetch = require('@brillout/fetch'); // npm install @brillout/fetch
// import fetch from '@brillout/fetch';

(async () => {
  const response = await fetch('https://brillout-misc.github.io/game-of-thrones/characters/list.json');
  const characters = await response.json();
  console.log(characters);
})();
