LiveReload and Guard (on Cloud9)
We will setup LiveReload and Guard to automatically refresh your browser whenever you make a change to a file. This saves you the hassle of clicking refresh or pressing F5 each time you want to see the effect of a change you made.
Add the following gems to the
:development group in your
group :development do # ... gem 'guard-livereload', '~> 2.5' gem 'rack-livereload', '~> 0.3.16' end
Run this in your bash console:
bundle install guard init livereload
Add one line to
Rails.application.configure do config.middleware.insert_after ActionDispatch::Static, Rack::LiveReload, host: 'YOUR CLOUD9 URL HERE', port: 8081 # ... end
If you're not on Cloud9, omit the
port: parameters. If you are on Cloud9, enter the URL you view your application at (without the https:// part).
If you're on Cloud9, replace this line in your
guard 'livereload' do
with this line:
guard 'livereload', port: 8081 do
guard in your bash terminal. You should see a line that says:
INFO - LiveReload is waiting for a browser to connect..
Now run your rails server. If you're on Cloud9 visit the page, but change
https in the address bar to
If everything worked correctly, you should see
INFO - Browser connected. in your guard console, and your page should refresh automatically when your files change!
