  • For using $resource Service, you just need to add Angular-resource script file after AngularJS and dependency of ngResource into Angular module, as shown in the syntax given below.
  • Step 5 – – – – The Service performs the work and return the status of the function, which is either successfully completed or rejected through deffered object to the client.
  • Promises are the pending results of the asynchronous calls and deferred objects returns promises and the results of asychronous operation after its completion to the calling code.The client sends asynchronous call to the Service.The Service receives the call and create a deferred object by using $q Service.The deferred object returns…
  • This function takes two parameters, the name of the Service and an object literal, which represents the Service.
  • Some of the commonly used built-in Services are shown below.This Service is used to communicate with the Servers over the network; i.e., you can send raw requests like getting and posting the data etc., and to recieve the resposne from the remote Server through this Service.This type of Service is…

This article will demonstrate built-in as well creating your own custom AngularJS Services with examples on Plunker Editor.

This article will demonstrate built-in AngularJS Services as well as how you can create your own custom service in an AngularJS. This article begins with a brief introduction to AngularJS Services. Afterwards, it demonstrates built-in AngularJS Service with syntax and links to an example on Plunker Editor. Finally, the article discusses custom AngularJS is used for the same purpose as $http Service but the key difference between them is that $resource is based on a RESTful architecture and is used to access Restful Web Services. For using $resource Service, you just need to add Angular-resource script file after AngularJS and dependency of ngResource into Angular module, as shown in the syntax given below.

$q

$q service is used to handle the promises and the deferred objects. Promises are the pending results of the asynchronous calls and deferred objects returns promises and the results of asychronous operation after its completion to the calling code.

How $q works

Step 1

The client sends asynchronous call to the Service.

Step 2

The Service receives the call and create a deferred object
