How to handle / ignore a bad route with durandal?

Question

I\'m trying to conditionally block a route from being accessed. I think this can be done with guardRoute: http://durandaljs.com/documentation/Router/

Answer 1

I am a newbie to durandaljs 2.0 having only used it for a couple of weeks so this was one of my first stumbling blocks. see my code below

router.guardRoute = function (routeInfo, params, instance) {
    var insecureRoutes = ['login', 'terms','signup','password'];
    if ($.inArray(params.fragment, insecureRoutes) || mymodule.isAuthenticated()) {
        return true;
    } else {
        return 'login/' + params.fragment;
    }
};

I also define a route for the login page like this

{ route: 'login/(:returnroute)', moduleId: 'viewmodels/login', nav: false },

This allows you to optionally specify a return rout so that after login you can redirect the user to where ever it is they were initially trying to go to. I hope it helps someone
