Switches between unfetch & node-fetch for client & server.

# Isomorphic Unfetch

Switches between [unfetch](https://github.com/developit/unfetch) & [node-fetch](https://github.com/bitinn/node-fetch) for client & server.

## Install

This project uses [node](http://nodejs.org) and [npm](https://npmjs.com). Go check them out if you don't have them locally installed.

> **Note:** This module uses node-fetch 3.x, which is ES Module and requires Node >= 12.20.0.

```sh
$ npm i isomorphic-unfetch
```

Then with a module bundler like [rollup](http://rollupjs.org/) or [webpack](https://webpack.js.org/), use as you would anything else:

```javascript
// using ES6 modules
import fetch from "isomorphic-unfetch";

// using CommonJS modules
const fetch = require("isomorphic-unfetch");
```

## Usage

As a [**ponyfill**](https://ponyfill.com):

```js
import fetch from "isomorphic-unfetch";

fetch("/foo.json")
  .then((r) => r.json())
  .then((data) => {
    console.log(data);
  });
```

Globally, as a [**polyfill**](https://ponyfill.com/#polyfill):

```js
import "isomorphic-unfetch";

// "fetch" is now installed globally if it wasn't already available

fetch("/foo.json")
  .then((r) => r.json())
  .then((data) => {
    console.log(data);
  });
```
