What steps can be taken to troubleshoot this AngularJS code?

When errors occur within Angular, debugging becomes quite challenging for me. Here is the code snippet I am working with:

<script>
    var my_app = angular.module("campaign_listing", ['$http']);
    var controllers = {};
    controllers.campaign_list_controller = function($http){
        var filters = {};
        var campaigns = {};
        this.update_fields = function(){
            console.log("update!");
        }
    }
    my_app.controller(controllers);
</script>

This code snippet triggers the following error message:

angular.js:38Uncaught Error: [$injector:modulerr] http://errors.angularjs.org/1.4.6/$injector/modulerr?p0=campaign_listing&p1…ogleapis.com%2Fajax%2Flibs%2Fangularjs%2F1.4.6%2Fangular.min.js%3A19%3A463)

And here is the non-minified version of the error:

Uncaught Error: [$injector:modulerr] Failed to instantiate module campaign_listing due to:
Error: [$injector:modulerr] Failed to instantiate module $http due to:
Error: [$injector:nomod] Module '$http' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.
http://errors.angularjs.org/1.4.6/$injector/nomod?p0=%24http

Since I am not utilizing routing, the provided link confuses me even further. Could someone please help identify the issue and provide guidance on how to approach debugging similar problems in the future?

Answer №1

If you're struggling to debug your Angular code, one suggestion is to create a breakpoint within the my_app.controller() line and step into the code (although this may be challenging for beginners).

Based on the code snippet provided, it seems like there might be more issues down the road as it doesn't quite follow typical Angular conventions. It's recommended to go through some tutorials first to familiarize yourself with Angular best practices.

Answer №2

While the previous response is accurate, another scenario where this issue may arise is when a Controller file is missing. In the example below, I had commented out the controller file at line 60, but I was still referencing it at line 13 with AppCtrl. By uncommenting line 60, the error disappeared.
