ngSweetAlert | AngularJS wrapper for SweetAlert | Wrapper library

You need to inject it first, like:

in your HTML type should be type='text/javascript' not type='text/javscript'

Javascript on mobile doesn't work good with social medias. It happens mostly because of security restrictions, certificates and so on. Keep in mind with Javascript you can fraud business logic by loading new javascript code after application has been published in AppsStore or Google Play. I believe Facebook blocks javascript implementation on mobile devices.

Some Cordova applications, for example US Bank .., even do not use $http or ajaxbecause of lack of SSL Pinning, they use native implementation for most of modules.

I trying to use ngFacebook on a mobile app but is does not work. I tested on desktop and it works perfect

What do you want to achieve? if you need login only , try official plugin for Facebook in Apache Cordova/PhoneGap - it uses native Facebook plugin. Or cordova-plugin-facebook4

Your dependencies are in the wrong order here. You must match the order of the dependencies in the array exactly with the parameters in the function. Also, you are expecting $watch in your function, but not including it in the dependency list.

Edit: If you are intending to use $scope.$watch rather than a $watch service that you created or installed, that isn't an injectable service. Therefore, it should not be passed as a function parameter.

Instead of:

The problem is explicitly written in your error.

SweetAlert is not defined

Meaning that in your controller you forgot to add SweetAlert to your dependencies.

just add SweetAlert to the end of your conrtoller line:

The module injector name is wrong, it should be 'oitozero.ngSweetAlert' rather than 'angular-sweetalert', also don't use require in the module injector. From angular.module says

A module is a collection of services, directives, controllers, filters, and configuration information. angular.module is used to configure the $injector.
