Issue: [$injector:unpr] encountered while configuring routing

Looking to implement a basic authentication system for my angularjs application. The problem arises when I try to debug the app.js on line 20, and an error is displayed:

Error: [$injector:unpr] http://errors.angularjs.org/1.2.16/$injector/unpr?p0=configProvider%20%3C-%20config

Does anyone have any insights on what might be causing this issue?

Here's the link to the plunkr example: http://plnkr.co/edit/k0dfl8ZFSCpYEBhuZMBf

Answer №1

If you're facing issues like this, one helpful starting point is to utilize the un-minified version of Angular (angular.js instead of angular.min.js). This way, you'll receive a more comprehensible error message:

Error: [$injector:unpr] Unknown provider: configProvider <- config

This error led us to your navbarController.js file where you are trying to inject the service config which has not been properly defined, resulting in the "Unknown provider" error:

var NavbarController = function ($scope, $location, config, authService) {

...

NavbarController.$inject = ['$scope', '$location', 'config', 'authService'];
