A step-by-step guide to incorporating dependencies in an AngularJS controller

I'm currently working on a MEANJS application and I want to integrate Snoocore into an AngularJS controller.

Find more about Snoocore here

'use strict';

angular.module('core').controller('HomeController', ['$scope', 'Authentication', 'Snoocore', function($scope, Authentication, Snoocore) {
        // Setting up the authentication context
        $scope.authentication = Authentication;

        var reddit = new Snoocore({
            userAgent: 'test@documentation',
            oauth: {
                type: 'implicit',
                mobile: true,
                key: '',
                redirectUri: 'redirectUri set for your app',
                scope: [ 'read', 'flair', 'identity' ]
            }
        });
    }
]);

I have added Snoocore via Bower and it can be found at

public/lib/snoocore

The controller file is located at

public/modules/core/controllers/home.client.controller.js

However, I am facing issues with the implementation and not sure what's going wrong. Being new to Angular and MEANJS, I could use some guidance.

The console is showing this error message:

Error: [$injector:unpr] Unknown provider: snoocoreProvider <- snoocore

Answer №1

I inserted a new tag

<script src="/lib/snoocore/dist/Snoocore-browser.min.js"></script>

into the HTML header and updated my controller code as shown below.

'use strict';


angular.module('core').controller('HomeController', ['$scope', 'Authentication' ,function($scope, Authentication) {
        // This provides Authentication context.
        $scope.authentication = Authentication;

        var reddit = new Snoocore({
            userAgent: 'test@documentation',
            oauth: {
                type: 'implicit', // required when using implicit OAuth
                mobile: true, // defaults to false.
                key: '', // Only requires the key! No secret needed.
                redirectUri: 'redirectUri set for your app',
                scope: [ 'read', 'flair', 'identity' ] // make sure to set all the scopes you need.
            }
        });

    }
]);

If you are utilizing the official library, injecting the dependency as a normal AngularJS module is not possible because it lacks an AngularJS provider.

I recommend using the library as you would with a standard JS library:

 var Snoocore = window.Snoocore;

'use strict';

angular.module('core').controller('HomeController', ['$scope', 'Authentication', function($scope, Authentication) {
        // This provides Authentication context.
        $scope.authentication = Authentication;

        var reddit = new Snoocore({
            userAgent: 'test@documentation',
            oauth: {
                type: 'implicit', // required when using implicit OAuth
                mobile: true, // defaults to false.
                key: '', // Only requires the key! No secret needed.
                redirectUri: 'redirectUri set for your app',
                scope: [ 'read', 'flair', 'identity' ] // make sure to set all the scopes you need.
            }
        });
    }
]);

Give this approach a try and hopefully it will resolve your issue.

Snoocore is not designed as an angular module, meaning it cannot be used directly as an angular dependency. To incorporate Snoocore into your Angular project, you have two options: either create a custom angular service/factory to encapsulate Snoocore, or access the global variable window.Snoocore. Additionally, ensure that you have included the Snoocore source file in your HTML.
