ES6 `fetch is undefined`

Question

I\'m building a site with ES6 and Babel.

In a script file, I need to make an ajax call to a service on server. For that I\'m doing like this:

fetch(\         


        

Answer 1

I prefer to use isomorphic-unfetch instead of isomorphic-fetch, because it is able to work like a ponyfill and not a polyfill.

The difference is that it doesn't affect the rest of code and it is more transparent of the dependencies you have.

Install:

yarn add isomorphic-unfetch

Usage:

// using ES6 modules
import fetch from 'isomorphic-unfetch';

// using CommonJS modules
var fetch = require('isomorphic-unfetch');
