var ApplicationController = Backbone.Router.extend({
  before: {
    '*any': '_logRoute'
  },

  _logRoute: function() {
    ...
  }
});


var PostsController = ApplicationController.extend({
  before: {
    '*any-post': '_checkAuth'
  },

  _checkAuth: function() {
    ...
  }
});

PostsController before filter should also have '*any': '_logRoute' inherited

Add note about how to run test.

I think karma config needs to be updated now.

JASMINE and JASMINE_ADAPTER are not supported anymore.

In backbone routes, the router stops matching in case it found a match. In case of the filter, it matched all the filters possible. For eg. If i have to match 'login' and then '*any', it will execute both the filter functions. Is there a way to stop the execution at the first match and not proceed.

https://github.com/chirag04/backbone-async-route-filter

Made a new module as adding async changed the philosophy of backbone-route-filter.

Async route filter uses express style next callback.

I have a RequireJS project and I encountered a situation where Backbone is loaded asynchronously via RequireJS after backbone-route-filter expects it to be available. If there is a way to load an AMD dependency before its non-AMD dependant, I haven't found it.

On that note, I've thrown together a quick way to make backbone-route-filter AMD compatible here. If you like, I can test this and open a pull request in a few days.

Thanks for the library!

Backbone 1.1 has a nice hook to bind additional logic to the router

Taking from the example below, lets say the checkAuthorization is making a ajax request to check the authorization.

Since ajax is asynchronous, I cannot return from checkAuthorization until the ajax is done.

How do i handle such cases?

var Router = Backbone.Router.extend({
  routes: {
    'users': 'usersList',
    'users/:id': 'userShow',
    'account/sign-in': 'signIn'
  },

  before: {
    // Using instance methods
    'users(:/id)': 'checkAuthorization',

    // Using inline filter definition
    '*any': function(fragment, args) {
      console.log('Atempting to load ' + fragment + ' with arguments: ', args);
    }
  },

  after: {
    // Google analytics tracking
    // After filter will be triggered only if all before filters passed and action was triggered,
    // so you'll only track pages that was displayed to user
    '*any': function(fragment) {
      goog._trackPageview(fragment);
    }
  },

  checkAuthorization: function(fragment, args) {
    if (!this._isSignedIn) {

      // Going to sign-in page
      this.signIn();

      // Preventing current route from being handled
      return false;
    }
  }
});
