[bit-bundler](https://github.com/MiguelCastillo/bit-bundler) plugin for minifying JavaScript

`bit-bundler-minifyjs` is actually a tiny wrapper for [UglifyJS](https://github.com/mishoo/UglifyJS2), so be sure to check it out for more details on all the available options.

# usage

## install

```

$ npm install --save-dev @bit/bundler-minifyjs

```

## bit-bundler setup

``` javascript

var Bitbundler = require("@bit/bundler");

var bitbundler = new Bitbundler({

  bundler: [

    "@bit/bundler-minifyjs"

  ]

});

bitbundler.bundle({

  src: "in.js",

  dest: "out.js"

});

```

## with code splitting

All options can actually be configured on a per bundle basis leveraging bundle names, which is really handy when spltting bundles.

``` javascript

var Bitbundler = require("@bit/bundler");

Bitbundler.bundle({

  src: "in.js",

  dest: "out.js"

}, {

  bundler: [

    ["@bit/bundler-splitter", {

      name: "vendor",

      dest: "dist/vendor.js",

      match: { path: /node_modules/ }

    }],

    ["@bit/bundler-minifyjs", {

      vendor: {

        sourceMap: false

      }

    }]

  ]

});

```

## bundle banner

A useful feature is adding a "banner" to the output minified file.

```

minifyjs({

  banner: "/*! (c) Miguel Castillo. Licensed under MIT */"

})

```

# options

All options are directly forwarded onto [UglifyJS](https://github.com/mishoo/UglifyJS2), so understanding what options are available is helpful if the default behavior isn't sufficient for you. For convenience, you can refer to the options below that are commonly used.

## `banner`

String value that is added to the top of the generated file. Useful for adding build and licensing information.  This option is a shorthand for `output.preamble` option in `UglifyJS`.

> This is a bit-bundler-minifyjs option, not an `UglifyJS` option. Internally, this is the `preamble` options in `UglifyJS`.

## `sourceMap`

Flag to disable sourcemap generation. Sourcemaps are generated inline, but they can be split out into a separate file with the plugin [bit-bundler-extractsm](https://github.com/MiguelCastillo/bit-bundler-extractsm). `sourceMap` is `true` by default.

> This is a bit-bundler-minifyjs option, not an `UglifyJS` option.
