Until now, we have dealt with data-binding in AngularJS. We have seen how to take data from our controllers and get it into the UI, and ensure that whenever the user interacts with or types in any data, we get it back into our controllers. We used and worked with some common directives, and dealt with forms and error handling. In this blog, we dive into AngularJS services.
By the end of the next few blogs, we will have a thorough understanding of AngularJS services and get some hands-on experience in using core built-in AngularJS services. After that, we will learn why and when we should create AngularJS services, and actually create a simple service ourselves.
AngularJS Services
AngularJS services are functions or objects that can hold behavior or state across our application. Each AngularJS service is instantiated only once, so each part of our application gets access to the same instance of the AngularJS service. Repeated behavior, shared state, caches, factories, etc. are all functionality that can be implemented using AngularJS services.
Let’s first take a look at why we need them.

Reading Time: 5 minutesIn the previous blog, we saw the ng-bind directive, or its equivalent double-curly {{ }} notation, which allowed us to take the data from our controllers and display it in the UI. That gives us our one-way data-binding, which is powerful in its own regard. But most applications we develop also have user interaction, and […]
