What steps can be taken to eliminate the include module error in Angular?

I created a simple demo on my PC which is working perfectly fine. However, when I tried to replicate it on jsfiddle to ask a question, I encountered the following error message:
Uncaught Error: [$injector:nomod] Module 'myapp' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.

Can someone please explain why this error occurs? I am able to retrieve data on my PC. My main question is how can I refresh or call the same web service after a certain period of time, for example, every 1 minute. In jQuery, we have the setInterval function - how can I achieve this in Angular?

Here is the fiddle: http://jsfiddle.net/acboLcv2/1/

var app=angular.module("myapp");

app.factory('test', function($http) {

    //This entire object is returned when the Service runs. It is a singleton
    //and its properties can be accessed from any controller

    return {


        stationDashBoard: function(callback,error) {
            $http.get('http://184.106.159.143:8180/FGRailApps/jservices/rest/a/departure?crsCode=VIC').success(callback).error(error);
        }
    }
});

function departureContrl($scope,test){
    $scope.loading=true;
    test.stationDashBoard(function(data){
        console.log(data);
        $scope.data=data.data;
        $scope.loading=false;
        //alert(data);
    },function(error){
        alert('error')
    }) ;

}

Thanks

There are a few key areas on your website that require attention:

Solving the module error:

Although it seems to be resolved, I recommend the following as a precaution:

  1. Make sure to include an empty array when declaring an angular module, like this:

    angular.module("test", []);

  2. Ensure that you reference the angular app in the HTML, typically within the body tag for most applications:

Dealing with CORS error

If you're attempting to fetch data from a different domain using $http.get(...), it may not work unless you implement CORS techniques or retrieve the data from the same domain. For example, hosting the code on http://184.106.159.143:8180 could resolve this issue.

Handling polling requests

If you need to regularly fetch data from a server, one method is to use $timeout along with the Angular Digest Loop. Here's a suggestion using $timeout:

Incorporate the $timeout function into your Angular code to efficiently retrieve and render data at specified intervals. Don't forget to call $scope.$apply() outside the digest loop to ensure proper rendering in Angular.
