ui-router is a 3rd-party module and is very powerful. It supports everything the normal ngRoute can do as well as many extra functions.
Here are some common reason ui-router is chosen over ngRoute:
ui-router allows for you to have strong-type linking between states based on state names. Change the url in one place will update every link to that state when you build your links with
ui-sref. Very useful for larger projects where URLs might change.
There is also the concept of the decorator which could be used to allow your routes to be dynamically created based on the URL that is trying to be accessed. This could mean that you will not need to specify all of your routes before hand.
You can easily determine if you are in a state or parent of a state to adjust UI element (highlighting the navigation of the current state) within your templates via
$stateprovided by ui-router which you can expose via setting it in
In essence, ui-router is ngRouter with more features, under the sheets it is quite different. These additional features are very useful for larger applications.
