RequireJS concatenating JS but not minifying

I'm using

version 0.9.8 on Rails 4.0.13. I'm running into an issue where requirejs is concatenating all of my JS files, but not minifying them.

Here's my requirejs.yml file:

'react' : 'react/react-with-addons'
'react-dom' : 'react/react-dom'
'react-router' : 'react-router/index'
'react-router-shim' : 'react-router-shim/react-router-shim'
'jquery' : 'jquery/dist/jquery'
'lodash' : 'lodash/lodash'
'flux' : 'flux/dist/Flux'
'es6-promise' : 'es6-promise/promise'
'event-emitter' : 'eventemitter2/lib/eventemitter2'
'object-assign' : 'object-assign/object-assign'
'async' : 'requirejs-plugins/src/async'
'moment' : 'moment/min/moment-with-locales.min'
'bootstrap' : 'bootstrap/bootstrap.min'
'material' : 'material-kit/material.min'
'material-kit' : 'material-kit/material-kit'
'jquery' : 'jquery/jquery.min'

exports: 'React'
deps: ['react-router-shim']
exports: 'ReactRouter'
deps: ['jquery', 'material', 'bootstrap']
deps: ['jquery', 'bootstrap']
deps: ['jquery']
exports: 'jquery'
exports: '_'
exports: 'ObjectAssign'

And after running
rake assets:precompile RAILS_ENV=production
, I look into
for the
file and see that it's just a big file with all of the JS concatenating. Here's my
file as well:

App::Application.configure do
# Settings specified here will take precedence over those in config/application.rb.

# Code is not reloaded between requests.
config.cache_classes = true

# Eager load code on boot. This eager loads most of Rails and
# your application in memory, allowing both thread web servers
# and those relying on copy on write to perform better.
# Rake tasks automatically ignore this option for performance.
config.eager_load = true

# Full error reports are disabled and caching is turned on.
config.consider_all_requests_local = false
config.action_controller.perform_caching = true

# Enable Rack::Cache to put a simple HTTP cache in front of your application
# Add `rack-cache` to your Gemfile before enabling this.
# For large-scale production use, consider using a caching reverse proxy like nginx, varnish or squid.

# Disable Rails's static asset server (Apache or nginx will already do this).

# Generate digests for assets URLs.
config.assets.digest = true

config.assets.version = '1.1'

# Specifies the header that your server uses for sending files.
# config.action_dispatch.x_sendfile_header = "X-Sendfile" # for apache
# config.action_dispatch.x_sendfile_header = 'X-Accel-Redirect' # for nginx

# Force all access to the app over SSL, use Strict-Transport-Security, and use secure cookies.
config.force_ssl = true

# Set to :debug to see everything in the log.
config.log_level = :info

# Prepend all log lines with the following tags.
# config.log_tags = [ :subdomain, :uuid ]

# Use a different logger for distributed setups.
# config.logger =

# Use a different cache store in production.
# config.cache_store = :mem_cache_store

# Enable serving of images, stylesheets, and JavaScripts from an asset server.
# config.action_controller.asset_host = ""

# Precompile additional assets.
# application.js, application.css, and all non-JS/CSS in app/assets folder are already added.
# config.assets.precompile += %w( search.js )

# Ignore bad email addresses and do not raise email delivery errors.
# Set this to true and configure the email server for immediate delivery to raise delivery errors.
# config.action_mailer.raise_delivery_errors = false

# Enable locale fallbacks for I18n (makes lookups for any locale fall back to
# the I18n.default_locale when a translation can not be found).
config.i18n.fallbacks = true

# Send deprecation notices to registered listeners.
config.active_support.deprecation = :notify

# Disable automatic flushing of the log to improve performance.
# config.autoflush_log = false

# Use default logging formatter so that PID and timestamp are not suppressed.
config.log_formatter =


It looks like
is successfully minifying my JS files individually in my app's
directory, but these files aren't joined together to create the


I found the issue.

There was a syntax error with my JavaScript source that was silently failing the build. It was only when I added logLevel: 0 to my requirejs.yml file that I was able to see the error Unexpected token operator «=», expected punc «,» (line: 11, col: 37, pos: 276).
