WebpackDriver

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.

Add this line to your application's Gemfile:

gem 'webpack_driver'

And then execute:

$ bundle

Or install it yourself as:

$ gem install webpack_driver

Initialization will create a package.json, yarn.lock, a bare-bones webpack.config.js and then run yarn install (via the Knitter gem).

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

Production compilation:

config = WebpackDriver::Configuration.new('/path/to/my/webpack.config.js')
compiler = WebpackDriver::Compile.new(config)
compiler.start
sleep 1 while compiler.alive?
p compiler.assets

Dev server:

config = WebpackDriver::Configuration.new('/path/to/my/webpack.config.js', {
    port: 8333
})
server = WebpackDriver::DevServer.new(config)
server.start
fail("failed to start webpack #{server.output}") unless server.alive?

# wait for server to compile startup assets
sleep 1 until server.valid?

puts "Webpack dev server running on port #{server.port} url=#{server.url}"

p server.assets.map{|asset| asset.file }
sleep 30 # do other stuff
server.stop
fail("failed to stop webpack #{server.output}") if server.alive?

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.
