1. Gemfile

gem 'browserify-rails', '1.5.0' # until fix: https://github.com/browserify-rails/browserify-rails/issues/101
gem 'react-rails'

Browserify-rails allows to use browserify within assets pipeline. React-rails is here only to allow to use #react_component (and thus, prerendering).

Note that jquery-rails can be removed from Gemfile, the npm version of jquery and jquery-ujs will be used instead.

Browserstack

My setup for configuring a Rails app with RSpec Feature tests that uses Capabara to test on a browserstack remote browser.

The browserstack docs only show either an RSpec or a Capabara setup.

What I wanted:

1. In development run my tests quickly with poltergiest.
2. Run nightly builds on CI to test against different web browsers using browserstack.
3. Have the option to visually run my tests with selenium with Chrome, Firefox etc.

Load lib files in production (Rails 5)

If you have your code defined in classes in lib/ folder you may have problems to load that code in production.

Autoloading is disabled in the production environment by default because of thread safety.

Change config/application.rb:

    config.autoload_paths << Rails.root.join("lib")
 config.eager_load_paths &lt;&lt; Rails.root.join("lib")
