|
------------------------
|
||||||
|
|
||||||
|
Dear Node.js Users:
|
||||||
|
|
||||||
|
You SHOULD NOT use this module. You already have [`Buffer`](https://nodejs.org/api/buffer.html) and [`thirty-two`](https://github.com/chrisumbel/thirty-two):
|
||||||
|
|
||||||
|
```javascript
|
||||||
|
var buf = new Buffer('I ½ ♥ 💩', 'utf8');
|
||||||
|
buf.toString('hex');
|
||||||
|
buf.toString('base64');
|
||||||
|
buf.toString('ascii');
|
||||||
|
buf.toString('utf8');
|
||||||
|
buf.toString('binary'); // deprecated, do not use
|
||||||
|
```
|
||||||
|
|
||||||
|
Install
|
||||||
|
-------
|
||||||
|
|
||||||
|
You just include the `index.js` in a lovely script tag.
|
||||||
|
|
||||||
|
```bash
|
||||||
|
bower install --save unibabel
|
||||||
|
```
|
||||||
|
|
||||||
|
```html
|
||||||
|
<script src="/bower_components/unibabel/index.js"></script>
|
||||||
|
```
|
||||||
|
|
||||||
|
Dear WebPack / Broccoli, Gulp / Grunt Users:
|
||||||
|
|
||||||
|
I don't know how your build systems work these days,
|
||||||
|
but Unibabel is exported as `Unibabel`
|
||||||
|
and you can access it as `window.Unibabel`.
