BrwyRails

Spawn watchify to compile js or compile js with browserify under backgroud by env.

gem 'brwy_rails'

What's this?

Under development, spawn watchify process and compile js with it. Under production, compile js once with browserify.

My motivation is browserify_rails is too slow.

How to use

# at your project root
npm init
npm install --save-dev watchify browserify

# or brwy_rails:npm_setup

bundle exec rake brwy_rails:npm_setup # create package.json and add watchify

Add config.brwy_rails.targets and access it by {name}.bundle.js

# config/application.rb
config.assets.precompile = ["application.bundle.js", "application.css"]
# brwy_rails
config.brwy_rails.targets = [
  "app/assets/javascripts/application.js"
]
Rails.application.config.middleware.use BrwyRails.Middleware
# config.brwy_rails.browserify_opts = "-t babelify" # your browserify compile command
# config.brwy_rails.verbose = true
# config.brwy_rails.target_suffix = ".bundle"
# config.brwy_rails.watch = Rails.env.development?
# config.brwy_rails.poll = false
# config.brwy_rails.polling_interval = 1000

Include javascript with .bundle suffix (configure it as config.brwy_rails.target_suffix)

<%= javascript_include_tag 'application.bundle'%>

On development

If you want to wait watchify compiling, use BrwyRails.Middleware.

# config/environments/development.rb
Rails.application.config.middleware.use BrwyRails.Middleware

CAUTION

On production build, we have to do rake brwy_rails:build manually before rake assets:precompile.

It will be called naturally with assets:precompile later.
