Brings Rails named routes to javascript

branch: master
Readme.md

JsRoutes

Generates javascript file that defines all Rails named routes as javascript helpers

Intallation

Your Rails Gemfile:

gem "js-routes"

Basic Setup (Asset Pipeline)

Require js routes file in application.js or other bundle

/*
= require js-routes
*/

Optional: If you need to customize routes file create initializer, like config/initializers/jsroutes.rb:

JsRoutes.setup do |config|
  config.option = value
})

Available options:

  • default_format - Format to append to urls. Default: blank
  • exclude - Array of regexps to exclude from js routes. Default: []
    • Note that regexp applied to named route not to URL
  • include - Array of regexps to include in js routes. Default: []
    • Note that regexp applied to named route not to URL
  • namespace - global object used to access routes. Default: Routes
    • Supports nested namespace like MyProject.routes
  • prefix - String representing a url path to prepend to all paths. Default: blank

Advanced Setup

You can generate routes files on the application side like this:

JsRoutes.generate!("#{path}/app_routes.js", :namespace => "AppRoutes", :exclude => /^admin_/, :default_format => "json")
JsRoutes.generate!("#{path}/adm_routes.js", :namespace => "AdmRoutes", :include => /^admin_/, :default_format => "json")

In order to generate javascript to string and manipulate them yourself use: Like:

routes_js = JsRoutes.generate(options)

Usage

Configuration above will create a nice javascript file with Routes object that has all the rails routes available:

Routes.users_path() // => "/users"
Routes.user_path(1) // => "/users/1"
Routes.user_path(1, {format: 'json'}) // => "/users/1.json"
Routes.new_user_project_path(1, {format: 'json'}) // => "/users/1/projects/new.json"
Routes.user_project_path(1,2, {q: 'hello', custom: true}) // => "/users/1/projects/2?q=hello&custom=true"
Routes.user_project_path(1,2, {hello: ['world', 'mars']}) // => "/users/1/projects/2?hello%5B%5D=world&hello%5B%5D=mars"

Using serialized object as route function arguments:

var google = {id: 1, name: "Google"};
Routes.company_path(google) // => "/companies/1"
var google = {id: 1, name: "Google", to_param: "google"};
Routes.company_path(google) // => "/companies/google"

In order to make routes helpers available globally:

jQuery.extend(window, Routes)

What about security?

js-routes itself do not have security holes. It makes URLs without access protection more reachable by potential attacker. In order to prevent this use :exclude option for sensitive urls like /admin_/

Spork

When using Spork and Spork.trap_method(Rails::Application::RoutesReloader, :reload!) you should also do:

Spork.trap_method(JsRoutes, :generate!)

Advantages over alternatives

There are some alternatives available. Most of them has only basic feature and don't reach the level of quality I accept. Advantages of this one are:

  • Rails3 support
  • Rich options set
  • Support Rails #to_param convention for seo optimized paths
  • Well tested
