$resource and REST API

REST is becoming the most popular choice of design pattern for the latest web services being developed. All new platforms, frameworks, and programming languages support REST standards out of the box. REST interfaces usually involve a collection of resources with identifiers, and supporting different actions using all HTTP verbs. For example, GET requests to a /users/ resource would fetch a list of users, and POST requests to /users/ can be used to create a new user. The identifier can be used in a GET request to the URL /users/john to fetch a specific user object with a unique identifier john.

$resource is an in-built factory that helps create a local resource object that integrates with the REST API implicitly. The resource object has in-built methods representing common methods such as save, get, delete, and so on. These methods internally interact with the API URL using the $http object. $resource is available only after injecting the ngResource module.
