## Why?
Because a wise man once said your source code should be transpiled with same tool as your tests to avoid any hidden bugs.

The usecase would be transpiling es* source code with Bublé and have tests match as well. An alternative to using `babel-register`

The primary transformer here is [Bublé](https://buble.surge.sh/#) we only use [Babel](https://babeljs.io) for support with module import/exports.


## Install

```sh
npm install buba --save-dev
```

## Usage

### Source code

**CLI**
```sh
buba -i input.js -o output.js
# or with a directory
buba -i src/ -o lib/
# to enable sourceMaps
buba -i input.js -o output.js -s
```

**API Usage**
```js
import { transformFile } from 'buba'

const { code, map } = transformFile('input.js', {
  buble: {} // buble options
  babel: {} // babel options
})
```

### Tests
```sh
mocha --require buba/register tests/**/*.js
# or
tape --require buba/register tests/**/*.js
```

With `mocha` you can also provide buba within the `mocha.opts` config file:

```sh
 --require buba/register
 --reporter spec
 --ui bdd
```

Currently we only plan to use Babel for modules but you can add support for something like generators by adding a `.babelrc` file.

**API Usage**

Just make sure that `buba` is the 1st thing you require

```js
require('buba/register')
const prelude = require('./prelude') // prelude has import/export, arrow functions, etc
```
