Components of a View
A view can consist of client-side assets (i.e. the UI that is exposed in Ambari Web) and server-side resources (i.e. the classes that expose REST end points). When the view loads into Ambari Web, the view UI can use the view server-side resources as necessary to deliver the view functionality.
Client-side Assets
The view does not limit or restrict what client-side technologies a view uses. You can package client-side dependencies (such as JavaScript and CSS frameworks) with your view.
Server-side Resources
A view can expose resources as REST end points to be used in conjunction with the client-side to deliver the functionality of your view application. Thees resources are written in Java and can be anything from a servlet to a regular REST service to an Ambari ResourceProvider (i.e. a special type of REST service that handles some REST capabilities such as partial response and pagination – if you adhere to the Ambari ResourceProvider interface).
