# WebpackDriver

[![Build Status](https://travis-ci.org/nathanstitt/webpack_driver.svg?branch=master)](https://travis-ci.org/nathanstitt/webpack_driver)

Control webpack from Ruby

WebpackDriver controls execution of both webpack and webpack-dev-server to serve assets in developer mode and to compile assets for production.

It runs the dev server in the background using the `childprocess` gem and monitors it's output to detect the current status.

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'webpack_driver'
```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install webpack_driver

## Usage

Initialization will create a `package.json`, `yarn.lock`, a bare-bones `webpack.config.js` and then run yarn install (via the [Knitter](https://github.com/nathanstitt/knitter) gem).

```ruby

config = WebpackDriver::Configuration.new(
    WebpackDriver::Configuration.new('/path/to/my/webpack.config.js')
)
config.generate!
```

Production compilation (TODO):
```ruby
compiler = WebpackDriver::Compiler.new
compiler.generate
p compiler.files
```

Dev server:

```ruby
process = WebpackDriver::DevServer.new
process.start
fail("failed to start webpack #{process.output}") unless process.alive?
puts "Webpack dev server running on port #{process.detected_port} url=#{process.detected_url}"
p process.assets.map{|asset| asset.file }
sleep 30
process.stop
```


## Development

After checking out the repo, run `bin/setup` to install dependencies. You can also run `bin/console` for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
