How Do AngularJS
Services Work?
Introduction
AngularJS, a popular JavaScript framework for building dynamic web applications, relies heavily on
services to share code and manage dependencies across the app. In this blog post, we will explore
how AngularJS services work, why they are essential, and how you can leverage them in your
applications. If you’re looking to enhance your skills, consider our Angular JS Online Training at
NareshIT.
What Are AngularJS Services?
Services in AngularJS are singleton objects or functions that carry out specific tasks. These services
are used to organize and share code across the application, making it more modular and easier to
maintain. AngularJS comes with several built-in services like $http, $route, and $timeout, but you
can also create custom services to suit your application’s needs.

Factory:
A factory is a function that returns an
object. This is the most common way to
create a service.
Service:
A service is a constructor function. It is
instantiated with the new keyword.
Provider:
A provider is a more flexible way to
create services, allowing configuration
during the config phase of the
application.
Using Services:
Once a service is created, it can be
injected into controllers, directives, or
other services.
Why Use
AngularJS
Serices?
Code Reusability: Services promote code reuse by
encapsulating logic that can be shared across multiple
components.
Separation of Concerns: By using services, you can keep
your controllers lean and focused on presentation logic,
while business logic resides in services.
Testing: Services are easier to test independently
compared to controllers or directives.
