How and when is it better to load .js and .css files in an angular SPA application?

Question

JavaScript

I have my own css and js file for each view, respectively, how and when to load it?
Here is the routing, but along with the template, you also need to load css and js files.

(function(){
    angular.module("app", ["ngRoute"])
        .config(function($routeProvider){
            $routeProvider.when("/registration", {
                templateUrl: "/templates/registration/form.html",
                controller: "registrationCtrl"
            });
            $routeProvider.otherwise({redirectTo: '/registration'});
        });
})();

Put everything in one file. There are very few cases where such a division is appropriate. I'm 99% sure yours isn't one of them.
