Switching from using ngRouter to ui-router is a common

After purchasing an angularjs template for my application, I noticed that ngRouter was used instead of ui-router, which I am more comfortable with. So, I decided to switch to ui-router and update all the routes. However, I encountered some extra code in my routes that I don't fully understand where to place. Here is the old route for my dashboard:

$routeProvider.when("/dashboard", {
    templateUrl: "views/dashboard.html",
    resolve: {
        deps: ["$ocLazyLoad", function(a) {
            return a.load([jqload.c3, jqload.sparkline])
            .then(function() {
                return a.load({
                    name: "app.directives",
                    files: ["scripts/lazyload/directives/sparkline.directive.js"]
                })
            })
            .then(function() {
                return a.load("angular-c3");
            })
            .then(function() {
                return a.load("easypiechart");
            })

        }]
    }
});

Here is the updated version using ui-router:

.state('admin.dashboard', {
    url: '/dashboard',
    views: {
        'content@': {
            templateUrl: '/_admin/views/dashboard.html',
            controller: 'DashboardCtrl'
        }
    }

However, there seems to be missing code affecting certain functionality of my dashboard. My question is, when using ui-router, where should I include the code in resolve:

resolve: {
        deps: ["$ocLazyLoad", function(a) {
            return a.load([jqload.c3, jqload.sparkline])
            .then(function() {
                return a.load({
                    name: "app.directives",
                    files: ["scripts/lazyload/directives/sparkline.directive.js"]
                })
            })
            .then(function() {
                return a.load("angular-c3");
            })
            .then(function() {
                return a.load("easypiechart");
            })

        }]
    }

This section on resolve is new to me as I'm still learning angularjs. Any advice on how to deal with this after transitioning to ui-router would be appreciated.

Answer №1

The resolve functionality in AngularJS ensures that all callbacks inside it are executed before the state is displayed. Both NgRouter and ui-router have this feature. If you want to learn more about it, check out this article.

Here's a sample code snippet that demonstrates how resolve can be used:

.state('admin.dashboard', {
    url: '/dashboard',
    views: {
        'content@': {
            templateUrl: '/_admin/views/dashboard.html',
            controller: 'DashboardCtrl'
        }
    },
    resolve: {
        deps: ["$ocLazyLoad", function($ocLazyLoad) {
            return $ocLazyLoad.load([jqload.c3, jqload.sparkline])
            .then(function() {
                return $ocLazyLoad.load({
                    name: "app.directives",
                    files: ["scripts/lazyload/directives/sparkline.directive.js"]
                })
            })
            .then(function() {
                return $ocLazyLoad.load("angular-c3");
            })
            .then(function() {
                return $ocLazyLoad.load("easypiechart");
            })

        }]
    }
})
