Use LiveReload With Rails for Faster Development

Permalink

LiveReload applies CSS/JS changes to Safari or Chrome without reloading the page, and automatically reloads when the html changes. Let that soak in for a minute. In this post I'll go over how to get it installed and working on your Rails projects.

The installation process has two steps. First we install a browser extension that listens for livereload events. Then we use guard to listen for system events and send information to the browser.

First install the livereload addon for chrome or safari.

In your rails project gemfile add

gem 'rb-fsevent'
gem 'guard-livereload'

Run

bundle install

Then run

guard init livereload && guard

To setup guard for livereload and start monitoring for file system events. The last step is to activate the browser extension. You will need to click the LiveReload button:

Now when you change a file in your view, Safari / Chrome will load the new content automatically.

Notes on RubyCocoa

The notes on the livereload repo are a little confusing. Livereload can also work via RubyCocoa (instead of guard- livereload). If you're running ruby 1.9.2 you cannot install RubyCocoa on it. RubyCocoa is not 1.9.x compatible. So I opt to use the browser extension and guard.
