Angular provides a very powerful means to transfer messages to scopes at different hierarchical level. We can dispatch an event upwards through the scope hierarchy by notifying all the registered "$rootScope.Scope" listeners in the hierarchy or downwards to all the child scopes. Angular provides these two functions to achieve the event...
Recently I discovered that every directive in AngularJS has a priority score assigned to it. While the page is loaded the priority plays a very important role in setting the order of the execution of various directives in single DOM Element. The priority is used to sort the directives before their "compile" function gets called. In simple...
Angular provide services for handling non-view logic, communication with server(back-end) and can holds data & state. These services are singleton objects that can be used to share and organize code. For doing so, angular provides us five cool ways to make a service on the bases of once need. Following are the five approaches that...
In AngularJS, we can easily write our own custom directives to achieve required functionality. There are certain attributes which we provide in directive definition like restrict , scope , template, link, transclude etc. There is one more attribute named : require , which gives us the liberty to include another directive and inject...

In almost every AngularJS Controller we use scope object which is auto injected by AngularJS in $scope named parameter. And that scope gets visible to marked HTML and its inner/child HTML, because of which HTML can access...
When we are working on MVC (or MVVM for AngularJS) Design-Patterns, our application is loosely coupled because of different independent components defined for e.g. Controller, View, Services, Modal/Data etc. All the components have their own work/role but today we will discuss only Services. Services are that part of application where...
Many a times, we see a requirement, where we have to write same functions in multiple controllers just to share a common functionality among them, which is a bad approach, because in future, if any changes are required to that function, we’ll have to make the changes manually in all the copies of that function where it is defined or if...
As we all of know that AngularJS is very popular and powerful front-end framework, which helps us to build rich UI/UX applications. AngularJS has many cool things/features, but today we will concentrate on routes only and will try to make a small single page application like Facebook/Gmail with the help of routes, where we will perform...
