Live Reloading in Rails


When developing the frontend of any application, the most tedious thing is refreshing the client/server. Luckily, when it came to HTML, I had live server; and when it came to Node, I had Nodemon. When it came to ruby, the server refreshed but not the client.

Rails Live Reload

Is a Rails live reloader for views, partials, css, and js. This means that every single time you save a .erb, .css or .js file, the page will reload to show the changes.


  1. In Gemfile add:
group :development do
  gem "rails_live_reload"
Enter fullscreen mode Exit fullscreen mode

In order to only download this gem in development. Then run bundle.

  1. Create Initializer
#Create config/initializers/rails_live_reload.rb and add
RailsLiveReload.configure do |config|
  # config.url = "/rails/live/reload"

  # Default watched folders & files
  # %r{app/views/.+\.(erb|haml|slim)$}
  # %r{(app|vendor)/(assets|javascript)/\w+/(.+\.(css|js|html|png|jpg|ts|jsx)).*}, reload: :always

  # More examples:
  # %r{app/helpers/.+\.rb}, reload: :always
  # %r{config/locales/.+\.yml}, reload: :always

  # config.enabled = Rails.env.development?
end if defined?(RailsLiveReload)
Enter fullscreen mode Exit fullscreen mode
  1. Enjoy! With just two steps you saved yourself hours of refreshing the client in Rails!
