JsRoutes

JsRoutes will enable you to use named Rails routes in JavaScript.

Installation

Add the gem requirement to your GEMFILE

gem 'js-routes', :git => 'git://github.com/sirlantis/js-routes.git'

I recommend that you also specify a :tag to prevent incompatibilties.

Configuration

Configuration is done in the application.rb of your Rails 3 app - accessible via config.jsroutes. The available options and their defaults:

# How the JavaScript object will be named
config.js_routes.global  = "Router"

# Should the JS file be minified?
config.js_routes.minify  = Rails.env.production?

# Where should the file be stored / be accessed at.
config.js_routes.path    = 'javascripts/router.js'

# Should JsRoutes be mounted as a **middleware** (development, Heroku) or write the file once at boot-time (production)?
# There is also a :write option which can cause issues if more instances are booted (cluster/mod_passenger).
config.js_routes.mode    = Rails.env.production? ? :write_once : :mount

Examples

Routes

get :signup, :as => :signup

resources :posts do
  resources :comments
end

Views

Router.signup_path()
> /signup

Router.signup_url()
> http://yourwebsite.com:3000/signup

Router.posts_path()
> /posts

Router.post_path(3)
> /posts/3

# nested resources
Router.post_comment_path(3, 4)
> /posts/3/comments/4

# named params, all same output
Router.post_path(3, "xml")
Router.post_path(3, {format: "xml"})
Router.post_path({id: 3, format: "xml"})
> /posts/3.xml

# additional params
Router.post_path({id: 3, format: "xml", foo: "bar"})
> /posts/3.xml?foo=bar

Compatibility

The way JsRoutes is built it should be able to handle all of Rails options for Routes (optional params etc.).
