$stateChangeStart not being fired when state Changes in UI-Router ES6?

Question

I am using Bable for ES6 and webpack. I am on angular 1.x.x and building an application. Till now I did not hit any problem. I want to have a functionality where I can track all the Route Changes. I am using UI-Router. The problem is that $stateChangeStart is not getting triggered anyways. The code is mentioned below.

/*All includes are taken care of. Please look at the run method*/

angular.module('chpApp', [
        uirouter,
        angular_animate,
        uibootstrap,
        formly,
        formlyBootstrap,
        ngMessages,
        angularLoadingBar,
        'ngNotificationsBar',
        'jkuri.datepicker',
        'LocalStorageModule',
        'ncy-angular-breadcrumb',
        'mgo-angular-wizard',
        'luegg.directives',
        'ngToast',
        'ui.mask',
        /*Application Modules*/
        angularnvd3,
        chpConstants,
        menu,
        header,
        breadcrumb,
        auth,
        dashboard,
        programs,
        device
    ])
    .run(['$rootScope', function($rootScope) {
        $rootScope.$on('$stateChangeStart', () => {
            console.log('lol')
        })
    }])
    .config(routing);

Please let me know what I ma doing wrong because the state is getting changed but the $stateChangeStart event never gets triggered. The run method is the place where I am hooking up with the $stateChangeStart listener.

I guess its something to do with ES6 and I am not able to find any reference. Thanks.

Answer 1

I had a similar problem and eventually realised that the stateChange* events have been deprecated and disabled by default in ui-router 1.0. I'm using 1.0.0-alpha0. The functionality provided by these events can now be achieved using transition hooks. This is covered in the release notes for the 1.0 alpha and can be read here: https://github.com/angular-ui/ui-router/releases/tag/1.0.0alpha0

Expanding on Eoins answer, you can use the hooks on $transitions in a component controller as below

        $transitions.onStart({}, ()=>{
            $log.log('In start')
        });
        $transitions.onFinish({}, ()=>{
            $log.log('In finish')
        });
