AngularJS Question

Attaching global functions and data to $rootScope on initialization in AngularJS

I'd like to have a "Global function" called the first time I launch my AngularJS application, or every time I refresh the page.

This function will call my server with

to get global information necessary to use my application. I need to access
in this function. After that, and only after this request finished, I'm using
to load the good controller.

app.config(['$routeProvider', function($routeProvider) {

I don't want the application do something before this action is finished. So I guess I have to use a "resolve", but I don't really know how to use it.

Any idea?

It's not the best way to solve your given problem, but here is a proposed solution for your question.

Anything inside run(...) will be run on initialization.

angular.module('fooApp').run(['$http', '$rootScope' function($http, $rootScope) {
 $http.get(...).success(function(response) {
     $rootScope.somedata = response;

 $rootScope.globalFn = function() {
   alert('This function is available in all scopes, and views');


Now an alert can be triggered in all your views, using ng-click="globalFn()".

Be aware that directives using a new isolate scope will not have access to this data if not explicitly inherited: $scope.inheritedGlobalFn = $rootScope.globalFn
