Angular Js Development

AngularJS is a web application framework that assists with creating single-page applications, one-page web applications that only require HTML, CSS, and JavaScript on the client side. Its goal is to augment web applications with model–view–controller (MVC) capability, in an effort to make both development and testing easier.

Angular services are substitutable objects that are wired together using dependency injection (DI). You can use services to organize and share code across your app.

Angular services are:

  • Lazily instantiated – Angular only instantiates a service when an application component depends on it.
  • Singletons – Each component dependent on a service gets a reference to the single instance generated by the service factory.
  • Angular offers several useful services (like $http), but for most applications you’ll also want to create your own.
