How can I bring up an "in progress" loading bar in between ui-router state transitions?

All we need is an easy explanation of the problem, so here it is.

I have an AngularJS application that uses ui-router. There are times when the application waits while moving from one state to another and while the resolves are still in progress.

Does anyone have (or have they seen) any examples of how I can present an “in-progress” loading bar on the screen just during the time of the resolve from the one state to another?

How to solve :

I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.

Method 1

You can use the events emitted by ui-router (as well as the native routeProvider).


Something like this:

function(event, toState, toParams, fromState, fromParams){ 
    $rootScope.stateIsLoading = true;

function(event, toState, toParams, fromState, fromParams){
    $rootScope.stateIsLoading = false;

Then in HTML:

<section ui-view ng-hide="stateIsLoading"></section>
<div class="loader" ng-show="stateIsLoading"></div>


You can use resolve to provide your controller with content or data
that is custom to the state. resolve is an optional map of
dependencies which should be injected into the controller.

If any of these dependencies are promises, they will be resolved and
converted to a value before the controller is instantiated and the
$stateChangeSuccess event is fired

Note: Use and implement method 1 because this method fully tested our system.
