Start up Angular with a Fire $http.get when the page loads

Question

Start up Angular with a Fire $http.get when the page loads

I am facing an issue where my $http.get() request is firing after the home page has already loaded. How can I ensure that the request fires before the page loads so I can utilize the returned data on the page?

Here is a snippet of the routing code:

var leisureApp = angular.module('leisureApp', ["ngRoute"]);

leisureApp.config(["$routeProvider", "$locationProvider",
    function ($routeProvider, $locationProvider) {
        // route configurations here
    }]);

HomeController:

angular.module('leisureApp')

    .controller('HomeController', ['$scope', 'ADAuth', function ($scope, ADAuth) {

        $scope.ADAuth = ADAuth;

    }])
    
    .factory('ADAuth', function ($http) {
        return $http.get('Home/GetUser');
    })

MVC Controller method:

public JsonResult GetUser()
{
    // controller logic here
}

Any suggestions or tips on how to resolve this issue would be greatly appreciated.

Answer №1

If you want to make a route dependent on a function value or promise in AngularJS, you need to use resolve. This feature allows you to inject the resolved data into your controller when it is instantiated.

$routeProvider
    .when("/news", {
        templateUrl: "newsView.html",
        controller: "newsController",
        resolve: {
            message: function(messageService){
                return messageService.getMessage();
            }
        }
    });

app.controller("newsController", function (message) {
    $scope.message = message;
});

It's important to note that the property name in the resolve object, in this case message, should match the injected value in your controller. If you are using array syntax for minification safety, the code would look something like this:

app.controller("newsController", ['message', function (message) {
    $scope.message = message;
}]);
