Rails Auto Reload

This is a short Video on adding auto reload for rails applications

Link to the : YOUTUBE CHANNEL

Link to the video : https://youtu.be/3H-vcOdFKYc

  • In the video i explain how to add Auto Reload for Rails Applications. It can be done with some few steps.

  • Below you can read all the steps in text form. For the video you can visit this LINK

  • Check this list at the end of this Readme to see the different locations that we needed to add new codes

For this we need to add guard-livereload and rack-livereload gem to our Gemfile. We need to add the gem to Development Group , because we need it only in Development

group :development do
  gem 'guard-livereload', '~> 2.5', require: false
  gem 'rack-livereload'
end

Then in the terminal write :

$ bundle install

This command will download and configure all needed Configs

  • Now in the Terminal write : 
    $ bundle exec guard init livereload
    This command will add Guardfile to the project.
  • Now we need add a line to our Rails middleware stack For this open config/environments/development.rb Add the code below to the end of the file 
    # Add Rack::LiveReload to the bottom of the middleware stack with the default options:
config.middleware.insert_after ActionDispatch::Static, Rack::LiveReload

We are all set now all we need is running the rails Server again with :

$ rails s

and in a new tab of the terminal run :

$ bundle exec guard

Now enjoy Developing while your browser refreshes after any change

Note:

If you had any Issues that the changes in scss files are not watched. In Guardfile add this line :

 # file needing a full reload of the page anyway
  watch(%r{app/assets/stylesheets/.+\.scss})

Make Sure to restart livereload and rails servers , otherwise the changes will not take effect

Locations:

  1. Gems we added in Gemfile
  2. Line we added in Middelware
  3. Line we added in Guardfile
