Angularjs Uncaught Error: [$injector:modulerr] when migrating to V1.3

Question

I am learning Angular.js and I am not able to figure out whats wrong with this simple code. It seems to look fine but giving me following error.

Answer 1

After AngularJS version 1.3 global controller function declaration is disabled

You need to first create an AngularJS module & then attach all the components to that specific module.

CODE

function Ctrl($scope) {
    $scope.age = 24;
}

angular.module('app', [])
    .controller('Ctrl', ['$scope', Ctrl]);

Specifically for your case, there is some issue with AngularJS 1.3.14 (downgrade it to 1.3.13 works fine). Though I'd prefer you to use angular 1.2.27 AngularJS 1.6.X, Which is more stable version & latest release of AngularJS.

Working Plunkr

UPDATE:

You could do your current code to working state by allow global controller declaration inside angular.config. But this isn't the correct way to run angular application.

function Ctrl($scope) {
    $scope.age = 24;
}

angular.module('app', [])
    .config(['$controllerProvider',
        function ($controllerProvider) {
            $controllerProvider.allowGlobals();
        }
    ]);
