How to use the client on Node environment (ReferenceError: fetch is not defined) ?

Cozy-Client relies on the fetch function included in browsers (or polyfilled). This function does not exist on Node environments so we have to provide a polyfill. An example using node-fetch:

import fetch from 'node-fetch'
import CozyClient from 'cozy-client'

global.fetch = fetch

Then you will be able to use all the client methods and fetch data correctly.

When using cozy-client on Node environment, you don’t have access to all React specific APIs. If, for any reason, you want to access these APIs, you can still import them from cozy-client/dist/react.
