## closure-compiler-brunch

Adds [Closure Compiler JS](https://github.com/google/closure-compiler-js) support to [brunch](http://brunch.io).

The Closure Compiler tool can produce highly optimized JavaScript code by static analysis, dead code removal and minification.

This plugin leverages the JavaScript implementation of Closure Compiler, hence _Java is not required_.

## Usage
Install the plugin via npm with:
```
npm install --save closure-compiler-brunch
```

**Important**: ES6 required. `node <= 4.X.X` not supported without `harmony` flag. See [node green](http://node.green/). 

The optimizations are applied in production builds by default. You can supply `-p` flag with your build command. 

Closure Compiler flags can be passed to the `compiler` via `config.plugins.closurecompiler` object, for example, the default flags are given below:

```coffeescript
config =
  plugins:
    closurecompiler:
      compilationLevel: 'SIMPLE'
      createSourceMap: yes
```

`compilationLevel` can either be `WHITESPACE_ONLY`, `SIMPLE`, or `ADVANCED`.
