I do a lot of prototyping of ideas for web apps. I got tired of configuring new rails apps all of the time.
This is a great starting point which allows me to go straight into hacking features which make the idea unique. Like a boss.
For the views: haml, sass, compass with the html5 boilerplate 'framework' from paul irish ( http://html5boilerplate.com )
For authentication: devise, cancan
For testing: Rspec2 with Spork to speed that shit up Cucumber with capybara / webdriver FactoryGirl Autotest with Growl Notifications
If you're not running a Mac: ( Run bundle install --without development_mac )
For deployment: Vlad the Deployer. Come on now.
The Good Shit
Comes wired up with socket.io and Juggernaut ( http://github.com/maccman/juggernaut ) for websockets style communication regardless of browser.
use Juggernaut.publish "channel_name", data from within the App and it will push data to that channel.
If you wish, a page automatically subscribes to channels based on the controller and action, and if it is an action which has a single resource... for example the show action on a given resource then it subscribes to a channel for that resource. This way you can target that specific resource's page for juggernaut updating.
To enable this, in your controller you would use:
enable_sockets_for :index, :show def index # sockets will be enabled here end
And then in your view, you will automatically subscribe to users_show, users_show_1 where 1 is the ID of the user you are viewing.
See application.js for how you can add functions to handle any data that comes over the socket.
