Make your Rails routes available in JS!

Supports Ruby 1.9.3+ and Rails 4.0+

• Add gem routesjs-rails to your Gemfile and run bundle install
• Run rails g routes_js:install
• Add //= require routesjs-rails to your application.js file.

Requiring routesjs-rails in your JS manifest, will create a global object called Routes. This object will have two methods for every named route in config/routes.rb; the path method and the url method.

The path version of the method will return the absolute path to the resource, while the url version will return the full (including protocol, hostname, port, etc) URL to the resource.

// e.g.
Routes.userPath(1);
Routes.rootUrl();

Suppose we have the following in config/routes.rb:

Rails.application.routes.draw do
  root: "home#index"
  get "/google", to: redirect("https://www.google.com/"), as: :google

  namespace :api do
    root "api#index"
    resources :users, only: [:index, :show]
  end
end

We would end up with the following routes being defined:

Parameters can be passed to a route using arguments to the path/url method. There are two ways to do this, using argument values in the order they're supplied, or by passing an object that responds to each route parameter name.

// route in rails: /users/:id/roles/:role_id
Routes.userRolePath(1, 2); // returns /users/1/roles/2
Routes.userRolePath({ id: 1, role_id: 2 }); // also returns /users/1/roles/2

You can generate format (json, html, etc) routes by passing an object with a format property. For example:

Routes.userRolePath({ id: 1, role_id: 2, format: "json" }) // returns /users/1/roles/2.json

You can also call the json(), html(), xml() and none() methods on routes. Doing so will override the default and object supplied formats. For example:

// assuming .html is the default format in config/initializers/routesjs-rails.rb
apiUsersPath(1) // returns /api/users/1.html
apiUsersPath({ id: 1, format: "xml" }) // returns /api/users/1.xml
apiUsersPath({ id: 1, format: "xml" }).json() // returns /api/users/1.json
apiUsersPath(1).none() // returns /api/users/1

The default format can be set by suppliying a :default_format option in the initializer.

# config/initializers/routesjs-rails.rb
RoutesJS::Routes.init(default_format: :json)

Formats specified on the object will override the default format.

Routes can be selectively included/excluded by passing an array of routes to either :only or :except in the initializer.

For example:

# in config/initializers/routesjs-rails.rb

# include routes using only
RoutesJS::Routes.init(only: [:root, :new_user])

# or to exclude routes using except
# RoutesJS::Routes.init(except: :root)

If you'd like to use your routes in a CommonJS module, you'll need to generate the module file by running the following (-o parameter is optional):

rails g routes_js:module [-o <full_path>]

By default, this will generate a JS module at app/assets/javascripts/routejs.js. If you've specified the -o option, the file will be placed where you specified.

Now you can use your module by requiring it: var Routes = require("routesjs")
