This backbone plugin is inspired by this pull request: jashkenas/backbone#299.

Basically, it enables you to have after and before filter for your Backbone.Router.

For example:

class BlogRouter extends Backbone.Router
  before: ->
    # all before hooks here

  after: ->
    # all after hooks here

That's it.

To install this, just include it after backbone.js is loaded.

For example in Rails 3.1,

//= require jquery
//= require jquery_ujs
//= require underscore
//= require backbone
//= require backbone_router_filter
