# EditorConfig: http://EditorConfig.org

# This files specifies some basic editor conventions for the files in this

# for your favorite!
#
# For a full list of possible values consult the reference.

#

# Stop searching for other .editorconfig files above this folder.

# Pick some sane defaults for all files.
[*]

# UNIX line-endings are preferred since:
# * git prefers them
# * servers run on Linux
# * most developers use Mac OS X

# No reason in these modern times to use anything other than UTF-8.

# Ensure that there's no bogus whitespace in the file.

indent_style = space

# Personal preference here. Smaller indent size means you can fit more on a line
# which can be nice when there are lines with several indentations.
indent_size = 2

# Prefer a more conservative default line length – this allows editors with
# sidebars, minimaps, etc. to show at least two documents side-by-side.
# Hard wrapping by default for code is useful since many editors don't support
# an elegant soft wrap; however, soft wrap is fine for things where text just
# flows normally, like Markdown documents or git commit messages. Hard wrap
# is also easier for line-based diffing tools to consume.

# Stats plugin for webpack [![Version](https://img.shields.io/npm/v/stats-webpack-plugin.svg)](https://www.npmjs.com/package/stats-webpack-plugin) [![Build Status](https://img.shields.io/travis/unindented/stats-webpack-plugin.svg)](http://travis-ci.org/unindented/stats-webpack-plugin) [![Dependency Status](https://img.shields.io/gemnasium/unindented/stats-webpack-plugin.svg)](https://gemnasium.com/unindented/stats-webpack-plugin)

Writes the stats of a build to a file.


## Installation

```sh
$ npm install --save-dev stats-webpack-plugin
```


## Usage

```js
var StatsPlugin = require('stats-webpack-plugin');

module.exports = {
  plugins: [
    new StatsPlugin('stats.json', {
      chunkModules: true,
      exclude: [/node_modules[\\\/]react/]
    })
  ]
};
```

Give webpack the `--profile` flag or set `profile: true` in `webpack.config` to get detailed timing measurements.
See [Webpack Profiling](https://webpack.github.io/docs/cli.html#profiling) for more detail.

## API

```js
new StatsPlugin(path: string, [options])
```

* `path`: The path of the result file, relative to your output folder.
* `options`: Options passed to [stats.toJson](https://webpack.js.org/api/node/#stats-object)


## Meta

* Code: `git clone git://github.com/unindented/stats-webpack-plugin.git`
