Swagger Scala Module

Build Status Maven Central

The goal of Swaggerâ„¢ is to define a standard, language-agnostic interface to REST APIs which allows both humans and computers to discover and understand the capabilities of the service without access to source code, documentation, or through network traffic inspection. When properly defined via Swagger, a consumer can understand and interact with the remote service with a minimal amount of implementation logic. Similar to what interfaces have done for lower-level programming, Swagger removes the guesswork in calling the service.

Swagger-scala-module is a pure scala module for use with the swagger framework.

Check out Swagger-Spec for additional information about the Swagger project, including additional libraries with support for SpringMVC, other languages and more.

See the Wiki!

The github wiki contains documentation, samples, etc. Start there.


This project is compatible with swagger-core 1.5.x or greater.


To enable the swagger-scala-module, include the appropriate version in your project:

  "io.swagger" %% "swagger-scala-module" % "1.0.7-SNAPSHOT"

Which will include the proper cross-publish version of swagger-scala-module.

How does it work?

Including the library in your project allows the swagger extension module to discover this module, bringing in the appropriate jackson library in the process. You can then use scala classes and objects in your swagger project.

Treatment of Option and required

All properties, besides those wrapped in Option or explicitly set via annotations @ApiModelProperty(required = false), default to required = true in the generated swagger model. See #7

How to hide model properties

@ApiModelProperty(hidden = true) does not work because Scala generates a field and a getter for public properties. The annotation will hide the getter, but the field of the same name will still be visible.

To hide the property, instruct the Scala compiler to annotate both the field and the getter:

import io.swagger.annotations.{ApiModel, ApiModelProperty}
import scala.annotation.meta.{field,getter}

case class Foo(
  @ApiModelProperty(value = "This will not be hidden!", hidden = true)
  stillVisible: Int,

  @(ApiModelProperty @field @getter)(value = "A hidden property", hidden = true)
  actuallyHidden: String


The following methods are available to obtain support for Swagger:

  • The Swagger Google Group - This would normally be your first stop to get support for Swagger. Here you can find previously asked question, and ask new ones. When asking a question, please provide as much information as you can regarding the environment you use (development language, library, versions.
  • The Issues tab - Please open feature requests and bugs here. If you're not sure you encountered a bug, or if it's a general usage question, please use the Google Group mentioned above.
  • IRC! you can find us on freenode in the channel #Swagger. You can talk with us directly there.
