Accessing factory defined in another module in angularjs

Question

Can we call the factory functions defined in one module from another module? If so, how?

Let's say my first module is defined in moduleOne.js file as:

var myModule = angular.module('MyServiceModuleOne', []);
myModule.factory('notify', function () {
    return {
        sampleFun: function () {
            // some code to call sampleFunTwo()
        },
    };
});

And my second module in moduleTwo.js as:

var myModuleTwo = angular.module('MyServiceModuleTwo', []);
myModuleTwo.factory('notifytwo', function () {
    return {
        sampleFunTwo: function () {
            // code
        },
    };
});

How to call sampleFunTwo() from sampleFun()?

Thanks.

Solution

You need to inject MyServiceModuleTwo into MyServiceModule:

var myModuleTwo= angular.module('MyServiceModuleTwo',[]);
var myModule= angular.module('MyServiceModuleOne', ['MyServiceModuleTwo']);

Then inject notifytwo into notify:

myModule.factory('notify', function(notifytwo) {
    return {
        sampleFun: function() {
            notifytwo.sampleFunTwo();
        }      
    };
});


myModuleTwo.factory('notifytwo', function() {
    return {
        sampleFunTwo: function() {
            alert('From notify two');
        }    
    };
});
