Browser, meet Ruby on Rails
= What is it?
Silverline is a Ruby on Rails plugin which gives the ability to run Ruby in
the browser to manipulate HTML or vector graphics. Having Ruby code run in
the browser elevates client programming in Rails to be first-class, and
integrated with the rest of the framework.
= Gimme!
> cd /path/to/rails/app/vendor/plugins/
> git clone git://
This repository holds the Rails plugin only. To get a demo application using
Silverline, visit
You'll also need: Silverlight 2 for Windows or Mac
Note: You can find the developer version of the Silverlight runtime in
More information on Lighthouse:
= What can it do?
Silverline can run Ruby on the client because of Silverlight, the 4 megabyte
download of the .NET Framework, and IronRuby, the implementation of Ruby on
.NET and the Dynamic Language Runtime. Silverline lets you do anything you
can do in Silverlight with IronRuby you can do from Rails, but a whole lot
Silverlight applications can use HTML and vector graphics with WPF (either
through code or XAML markup for rendering their UI; silverline integrates
this capability into Rails by enabling Ruby and XAML partials.
== Easier from Rails
Ruby partials can even use RJS, so simply renaming foo.rjs to foo.rb will
avoid the server-side JavaScript generation and actually runfoo.rb on the client.
XAML partials give you the ability to render XAML without having to bootstrap
Silverlight yourself. XAML partials can also be passed through ERb for
server-side or client-side processing.
== Experimental
Note: the following is still a work-in-progress; your feedback is appreciated:
Silverline also lets you run pieces of your Rails application on the client,
removing the need to write a separate JavaScript or Flash application simply
to move functionality to the client. This is accomplished by flagging certain
actions as "client", and running the necessary pieces of your Rails appliation
and Rails itself on IronRuby in the browser.
You can also decorate ActiveRecord models with "acts_as_client" so any calls
to ActiveRecord on the client get translated into ActiveResource calls to a
restful API on the ActiveRecord model that was decorated.
