In this blog, we will see how Swagger UI can be generated with Akka HTTP.
Swagger allows developers to effectively interact and try out each and every route that your application exposes and it automatically generates UI from the Swagger specification. The visual documentation makes it easy for developers and clients to interact with the application.

"com.github.swagger-akka-http" % "swagger-akka-http_2.11" % "0.14.0"
The Swagger.scala contains a
routesproperty which can be concatenated along with existing akka-http routes.
<baseUrl>/<specPath>/<resourcePath>with the specified
swaggerVersionand resource listing.
Akka-Http routing provides a way to concatenate various HTTP routes which are composed of one or more level of directives that narrows down to handle each specific request.
