RequireJS concatenating JS but not minifying

I'm using requirejs-rails 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:
paths:
'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'
shim:
'react-router-shim':
exports: 'React'
'react-router':
deps: ['react-router-shim']
exports: 'ReactRouter'
'material-kit':
deps: ['jquery', 'material', 'bootstrap']
'material':
deps: ['jquery', 'bootstrap']
'bootstrap':
deps: ['jquery']
exports: 'jquery'
'lodash':
exports: '_'
'object-assign':
exports: 'ObjectAssign'
And after running rake assets:precompile RAILS_ENV=production, I look into public/assets for the application-HASH file and see that it's just a big file with all of the JS concatenating. Here's my production.rb 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

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 = ::Logger::Formatter.new
end
EDIT
It looks like requirejs-rails is successfully minifying my JS files individually in my app's tmp/requirejs/dst directory, but these files aren't joined together to create the application-HASH.js file.

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).

Rails 4 - In production my javascript is loaded but does not work while it works well in development

I work with :
Rails version 4.2.3
Ruby version 2.2.1
I have managed to run my application in production doing these steps :
rake db:create RAILS_ENV=production
rake db:migrate RAILS_ENV=production
rake assets:precompile and rake assets:precompile RAILS_ENV=production
I had some troubles with my application.js and application.css files because all the require were not in the right orders. I had to put require_tree at the bottom and require jquery at the top directly followed by require jquery_ujs.
Now my files are the following :
application.js file :
//= require jquery
//= require jquery_ujs
//= require bootstrap
//= require dataTables/jquery.dataTables
//= require dataTables/extras/dataTables.tableTools
//= require_tree .

However all the javascript that I wrote is not working in production. I looked into my browser consol and my javascript is loaded I can see it in the DOM when I right click "inspect element".
So why my javascript works in development but is not working in production ?
I tried several options :
1st try : I add the line config.assets.precompile += %w( *.css *.js)
2nd try : config.assets.precompile += %w( *.css *scss *.js)
3rd try : I found that in config/initializers/assets.rb was a line of code very similar to what I tried in my 1st and 2nd try so I enabled this line of code in config/initializers/assets.rb : Rails.application.config.assets.precompile += %w( search.js ) but I still have nothing.
4th try : I read in another post on Stackoverflow that removing in my GemFile jquery-ui-rails could work but I still have no javascript
Here is my GemFile :

Would anyone have an idea about what's happening ? Why my javascript is not working in production but works well in development ?

In production mode, it should server by web servers(Apache, Nginx) and will work. until that fix you can load all files in production rather loading a compressed single application.js and application.css file. For that in production.rb file disable the config variable. like below
config.serve_static_assets = false

The problem lies within your application.js and more specifically I believe where your bootstrap is being called. What fixed it for me was moving bootstrap to the bottom.
Asset pipeline is disabled in dev which is why you did not experience the same issues there.

Rails Application Not Loading All javascript files production

I am working on a personal website Hosted in AWS. Using Ruby 1.9.3 Rails 4.1.0beta1. When I run the code locally, it works like a charm. However when I push to AWS, its missing either some JS files or some CSS files. I think it is missing JS files because if I remove the following from application.js
//= require_tree .
I can reproduce the issue locally.
Here is my Gem file:

Here is a snippet of the html.erb page.
<%= stylesheet_link_tag "application", media: "all",
"data-turbolinks-track" => false %>
<%= javascript_include_tag "application", "data-turbolinks-track" => false %>
I can't quite figure out which files are missing. Please let me know if you need more information. I have been looking around all over and haven't been able to resolve this issue.
I have tried this: Rails 4: assets not loading in production.

I was able to resolve this issue:
1) I had an extra ) in my css file. I removed that to address the compile error that AWS was giving.
2) In my Application.js file I manually required all JS files needed instead of just using the tree:
//= require jquery
//= require modernizr
//= require bootstrap
//= require jquery.fitvids
//= require jquery.easing.1.3
//= require twitter
//= require jquery.fancybox.pack
//= require jquery.fancybox-thumbs
//= require jquery.fancybox-media
//= require stellar
//= require nicescroll.min
//= require jquery.isotope.min
//= require custom
//= require custom-home
//= require portfolio
//= require jquery.flexslider
//= require retina
3) I added gem 'sprockets', '2.8' to my GemFile which i had previously omitted.

Try
RAILS_ENV=production bundle exec rake assets:precompile
Also check your prod server and make sure the asset files are there under public.

Javascript not loading in Rails Test Environment

I can't get Javascript to load in the browser in the rails test environment. This is problematic for cucumber selenium tests through capybara. Here's my test.rb (the default as far as I know)
MyApp::Application.configure do
# Settings specified here will take precedence over those in config/application.rb
# The test environment is used exclusively to run your application's
# test suite. You never need to work with it otherwise. Remember that
# your test database is "scratch space" for the test suite and is wiped
# and recreated between test runs. Don't rely on the data there!
config.cache_classes = true
# Configure static asset server for tests with Cache-Control for performance
config.serve_static_assets = true
config.static_cache_control = "public, max-age=3600"
# Log error messages when you accidentally call methods on nil
config.whiny_nils = true
# Show full error reports and disable caching
config.consider_all_requests_local = true
config.action_controller.perform_caching = false
# Raise exceptions instead of rendering exception templates
config.action_dispatch.show_exceptions = false
# Disable request forgery protection in test environment
config.action_controller.allow_forgery_protection = false
# Tell Action Mailer not to deliver emails to the real world.
# The :test delivery method accumulates sent emails in the
# ActionMailer::Base.deliveries array.
config.action_mailer.delivery_method = :test
# Raise exception on mass assignment protection for Active Record models
config.active_record.mass_assignment_sanitizer = :strict
# Print deprecation notices to the stderr
config.active_support.deprecation = :stderr
end
This results in a concatinated application.js with everything. I've tried adding config.assets.debug = true so that the assets aren't concatinated, and then only sometimes the javascript is loaded. If I copy over development.rb it seems to work, but that doesn't seem ideal.
Thanks!

Turns out it was the less-rails-bootstrap version 3.0.1 gem was loading twitter/bootstrap in the wrong order due to inter-dependencies. We never noticed this is in development because Rails does not compress assets in the development environment, by default. So those particular files weren't being loaded, but they didn't keep all of our javascript from loading like they were in test.
Upgrading to less-rails-bootstrap 3.0.3, or requiring individual components of twitter/bootstrap in the correct order in application.js solved the problem.

Rails Heroku Precompiled Assets Not Loading JS?

I'm setting up my Rails app on Heroku, and running into a problem where all my CSS assets are loaded but none of my JS assets are. I'm using memcached, and followed these instructions: https://devcenter.heroku.com/articles/rack-cache-memcached-rails31.
One thing I noticed is that when I change config.assets.compile to "true" in my production.rb file, all the JS is loaded successfully but obviously the initial load of the site is tremendously slow. How can I troubleshoot this problem? I'm new to Heroku, so am unsure and haven't found anything online that is helpful.
I assume that since all my JS files are in /assets/javascripts/, that the should be included automatically, but it seems as if they're not.
Here's my production.rb:
BrainDb::Application.configure do
# Settings specified here will take precedence over those in config/application.rb
client = Dalli::Client.new
config.action_dispatch.rack_cache = {
:metastore => client,
:entitystore => client,
:allow_reload => false
}
# Code is not reloaded between requests
config.cache_classes = true
# Full error reports are disabled and caching is turned on
config.consider_all_requests_local = false
config.action_controller.perform_caching = true
# Disable Rails's static asset server (Apache or nginx will already do this)
config.serve_static_assets = true
config.static_cache_control = "public, max-age=2592000"
# Compress JavaScripts and CSS
config.assets.compress = true
# Don't fallback to assets pipeline if a precompiled asset is missed
config.assets.compile = false
# Generate digests for assets URLs
config.assets.digest = true
config.i18n.fallbacks = true
# Send deprecation notices to registered listeners
config.active_support.deprecation = :notify
end
I also removed everything from public/assets so it would precompile. Here's application.rb:
require File.expand_path('../boot', __FILE__)
require 'rails/all'
if defined?(Bundler)
# If you precompile assets before deploying to production, use this line
Bundler.require(*Rails.groups(:assets => %w(development test)))
# If you want your assets lazily compiled in production, use this line
# Bundler.require(:default, :assets, Rails.env)
end
module BrainDb
class Application < Rails::Application
# Configure the default encoding used in templates for Ruby 1.9.
config.encoding = "utf-8"
# Configure sensitive parameters which will be filtered from the log file.
config.filter_parameters += [:password]
# Enable escaping HTML in JSON.
config.active_support.escape_html_entities_in_json = true
config.active_record.whitelist_attributes = true
config.assets.initialize_on_precompile = false
# Enable the asset pipeline
config.assets.enabled = true
config.cache_store = :dalli_store
# Version of your assets, change this if you want to expire all your assets
config.assets.version = '1.0'
end
end
UPDATE
Application.js:
//
//= require jquery
//= require jquery_ujs

Add
//= require_tree . at last and precompile
in your application.js.
