List of Artifacts

Ktor is divided into modules to allow fine-grained inclusion of dependencies based on the functionality required. The typical Ktor application would require ktor-server-core and a corresponding engine depending on whether it’s self-hosted or using an Application Server.

All artifacts in Ktor belong to io.ktor group and hosted on JCenter and Maven Central. Pre-release versions are published at Bintray

Ktor is split into several groups of modules:

• ktor-server contains modules that support running the Ktor Application with different engines: Netty, Jetty, Tomcat, and a generic servlet. It also contains a TestEngine for setting up application tests without starting the real server
  • ktor-server-core is a core package where most of the application API and implementation is located
  • ktor-server-jetty supports a deployed or embedded Jetty instance
  • ktor-server-netty supports Netty in embedded mode
  • ktor-server-tomcat supports Tomcat servers
  • ktor-server-servlet is used by Jetty and Tomcat and allows running in a generic servlet container
  • ktor-server-test-host allows running application tests faster without starting the full host
• ktor-features groups modules for features that are optional and may not be required by every application
