I started using ocLazyload to lazy load few of my AngularJs controllers. I have used it along with the $routeProvider
like this
$routeProvider.when("/login", {
templateUrl: "login.html",
resolve: {
loadCtrl: ['$ocLazyLoad', function($ocLazyLoad) {
return $ocLazyLoad.load('LoginCtrl.js');
}]
}
}).
and this works fine.
I have another route definition which uses resolve
property to resolve few items before loading the controller.
when("/dashboard", {
templateUrl: "dashboard.html",
controller: "DashboardCtrl",
resolve: {
profileData: getProfile,
count : getCount
}
}).
Now I want to lazy load this controller too, and I tried it like this
when("/dashboard", {
templateUrl: "dashboard.html",
resolve: {
profileData: getProfile,
count : getCount,
loadCtrl: ['$ocLazyLoad', function($ocLazyLoad) {
return $ocLazyLoad.load(['DashboardCtrl.js']);
}]
}
}).
The page loads in this case, but the profileData
and count
doesn't get injected into the controller. The controller definition is as given below.
var app = angular.module('gt');
app.controller('DashboardCtrl', ['$scope', '$rootScope', 'profileData', 'count',
function($scope, $rootScope, profileData, count) {
...
}]);
On debugging, I realise that the getProfile
and getCount
method get's called, but it happens asynchronously and the controller also lazy loads without waiting for these methods. How do I inject and lazy load at the same time? Can I use promises to resolve this in any way?
I am using AngularJS 1.3.10 & ocLazyLoad 1.0.5 versions
getProfile
function for reference
var getProfile = function($q, $http, Profile, localStorageService) {
var deferred = $q.defer();
if (!localStorageService.get("loggedInUser")) {
$http.post('/loggedin').success(function(user) {
if (user) {
localStorageService.set("loggedInUser", user.email)
Profile.get(localStorageService.get("loggedInUser"), function(profileData) {
if (profileData) {
deferred.resolve(profileData);
} else {
deferred.resolve();
}
});
} else {
deferred.reject();
}
});
} else {
Profile.get(localStorageService.get("loggedInUser"), function(profileData) {
if (profileData) {
deferred.resolve(profileData);
} else {
deferred.resolve();
}
});
}
return deferred.promise;
}
getProfile.$inject = ["$q", "$http", "Profile", "localStorageService"];
I could get this working with the following configuration of $routeProvider
when("/dashboard", {
templateUrl: "dashboard.html",
controller :"DashboardCtrl"
resolve: {
profileData: getProfile,
count : getCount,
loadCtrl: ['$ocLazyLoad', function($ocLazyLoad) {
return $ocLazyLoad.load(['DashboardCtrl.js']);
}]
}
}).
where DashboardCtrl
is the controller defined in DashboardCtrl.js
