The RESTful Web Services module provides Views plugins that allow you to expose data over Views for your RESTful API. This allows you to create a view that has a path and outputs data using a serializer plugin. You can use this to output entities, such as JSON, HAL JSON, or XML, and it can be sent with appropriate headers.
In this recipe, we will create a view that outputs the users of the Drupal site, providing their username, e-mail, and picture if provided.
