What is stateProvider in AngularJS?

$stateProvider is used to define different states of one route. You can give the state a name, different controller, different view without having to use a direct href to a route. There are different methods that use the concept of $stateprovider in AngularJS.

What is ngRoute AngularJS?

AngularJS ngRoute module provides routing, deep linking services and directives for angular applications. We have to download angular-route. js script that contains the ngRoute module from AngularJS official website to use the routing feature. You can also use the CDN in your application to include this file.

Both do the same work as they are used for routing purposes in SPA(Single Page Application).

1. Angular Routing - per $routeProvider docs

URLs to controllers and views (HTML partials). It watches $location.url() and tries to map the path to an existing route definition.

HTML

<div ng-view></div>

Above tag will render the template from the $routeProvider.when() condition which you had mentioned in .config (configuration phase) of angular

Limitations:-

  • The page can only contain single ng-view on page
  • If your SPA has multiple small components on the page that you wanted to render based on some conditions, $routeProvider fails. (to achieve that, we need to use directives like ng-include, ng-switch, ng-if, ng-show, which looks bad to have them in SPA)
  • You can not relate between two routes like parent and child relationship.
  • You cannot show and hide a part of the view based on url pattern.

2. ui-router - per $stateProvider docs

AngularUI Router is a routing framework for AngularJS, which allows you to organize the parts of your interface into a state machine. UI-Router is organized around states, which may optionally have routes, as well as other behavior, attached.

Multiple & Named Views

Another great feature is the ability to have multiple ui-views in a template.

While multiple parallel views are a powerful feature, you'll often be able to manage your interfaces more effectively by nesting your views, and pairing those views with nested states.

HTML

<div ui-view>
    <div ui-view='header'></div>
    <div ui-view='content'></div>
    <div ui-view='footer'></div>
</div>

The majority of ui-router's power is it can manage nested state & views.

Pros

  • You can have multiple ui-view on single page
  • Various views can be nested in each other and maintained by defining state in routing phase.
  • We can have child & parent relationship here, simply like inheritance in state, also you could define sibling states.
  • You could change the ui-view="some" of state just by using absolute routing using @ with state name.
  • Another way you could do relative routing is by using only @ to change ui-view="some". This will replace the ui-view rather than checking if it is nested or not.
  • Here you could use ui-sref to create a href URL dynamically on the basis of URL mentioned in a state, also you could give a state params in the json format.

For more Information Angular ui-router

For better flexibility with various nested view with states, I'd prefer you to go for ui-router

Angular's own ng-Router takes URLs into consideration while routing, UI-Router takes states in addition to URLs.

States are bound to named, nested and parallel views, allowing you to powerfully manage your application's interface.

While in ng-router, you have to be very careful about URLs when providing links via <a href=""> tag, in UI-Router you have to only keep state in mind. You provide links like <a ui-sref="">. Note that even if you use <a href=""> in UI-Router, just like you would do in ng-router, it will still work.

So, even if you decide to change your URL some day, your state will remain same and you need to change URL only at .config.

While ngRouter can be used to make simple apps, UI-Router makes development much easier for complex apps. Here its wiki.
