+# abab
+
+[![npm version](https://badge.fury.io/js/abab.svg)](https://www.npmjs.com/package/abab) [![Build Status](https://travis-ci.org/jsdom/abab.svg?branch=master)](https://travis-ci.org/jsdom/abab)
+
+A module that implements `window.atob` and `window.btoa` according to the [WHATWG spec](https://html.spec.whatwg.org/multipage/webappapis.html#atob). The code is originally from [w3c/web-platform-tests](https://github.com/w3c/web-platform-tests/blob/master/html/webappapis/atob/base64.html).
+
+Compatibility: Node.js version 3+ and all major browsers (using browserify or webpack)
+
+Install with `npm`:
+
+```sh
+npm install abab
+```
+
+## API
+
+### `btoa` (base64 encode)
+
+```js
+const btoa = require('abab').btoa;
+btoa('Hello, world!'); // 'SGVsbG8sIHdvcmxkIQ=='
+```
+
+### `atob` (base64 decode)
+
+```js 
+const atob = require('abab').atob;
+atob('SGVsbG8sIHdvcmxkIQ=='); // 'Hello, world!'
+```
+
+#### Valid characters
+
+[Per the spec](https://html.spec.whatwg.org/multipage/webappapis.html#atob:dom-windowbase64-btoa-3), `btoa` will accept strings "containing only characters in the range `U+0000` to `U+00FF`." If passed a string with characters above `U+00FF`, `btoa` will return `null`. If `atob` is passed a string that is not base64-valid, it will also return `null`. In both cases when `null` is returned, the spec calls for throwing a `DOMException` of type `InvalidCharacterError`.
+
+## Browsers
+
+If you want to include just one of the methods to save bytes in your client-side code, you can `require` the desired module directly.
+
+```js
+var atob = require('abab/lib/atob');
+var btoa = require('abab/lib/btoa');
+```

+If you're **submitting a PR** or **deploying to npm**, please use the [checklists in CONTRIBUTING.md](https://github.com/jsdom/abab/blob/master/CONTRIBUTING.md#checklists)
+
+### Remembering `atob` vs. `btoa`
+
+Here's a mnemonic that might be useful: if you have a plain string and want to base64 encode it, then decode it, `btoa` is what you run before (**b**efore - **b**toa), and `atob` is what you run after (**a**fter - **a**tob).
