Learning Scala Web Development (Video 16)

The video tutorial discusses the use of Swagger for documenting RESTful web services and APIs, focusing on its integration with the Spray framework. It covers the setup of Swagger HTTP Service, the use of various Swagger annotations to enrich API documentation, and the process of exposing this documentation through resource and API listings. The tutorial emphasizes the importance of well-documented APIs and introduces the concept of resource listings as a way to expose API metadata. The video concludes with a preview of the next topic, which is the Swagger UI tool.

What was the primary reason for choosing Swagger to document the book application?

• It is the only tool available.

• It integrates well with Spray applications.

• It is a paid tool with premium features.

• It requires no annotations.

What is the role of the Swagger HTTP service in the integration with Spray?

• It is a standalone application.

• It is a trait that needs to be inherited.

• It is a database service.

• It is a graphical user interface.

Which annotation is used to describe a top-level Web API in Swagger?

• @APIParam

• @APIResponse

• @APIModel

• @API

What is the purpose of the @APIResponse annotation?

• To describe the input parameters.

• To describe the type of response an operation returns.

• To describe the base URL.

• To describe the API version.

How is API documentation typically exposed in Swagger?

• Through email notifications.

• Through a desktop application.

• Through a resource listing and API listing endpoints.

• Through a command-line interface.

What is a limitation of the current Spray Swagger integration?

• It is not compatible with JSON format.

• It supports only Swagger specification 1.2.

• It does not support any annotations.

• It cannot be used with any framework.

Why might a tool be needed to visualize the Swagger documentation?

• The JSON format is not very usable as is.

• The documentation is in XML format.

• The documentation is only available in print.

• The documentation is encrypted.
