# purs-loader

> [PureScript](http://www.purescript.org) loader for [webpack](http://webpack.github.io)

- Supports hot-reloading and rebuilding of single source files
- Dead code elimination using the `bundle` option
- Colorized build output using `purescript-psa` and the `psc: "psa"` option

## Install

      exclude: /node_modules/,
      query: {
