Home Routing

How would one implement the following angular route in the context of TypeScript ?

And where would be the best place to place this ?

Example of angular route:

angular.module('App', ['ngRoute']).config(['$routeProvider', function ($routeProvider) {

    $routeProvider.when("/Main", {
        controller: "MainCtl",
        templateUrl: "/Views/Main.ascx",
    }).when("/DoSomething", {
        controller: "doSomethingCtl",
        templateUrl: "/Views/DoSometing.ascx",
    }).otherwise({ redirectTo: "/Main" });

}]);
