Ktor
Kotlin framework for building asynchronous servers and HTTP clients, extended with plugins and engines.
Ktor is a Kotlin framework for asynchronous servers and HTTP clients. A server can run as a self-contained application that starts an engine such as Netty, Jetty, Tomcat or CIO and listens on a port, or as a servlet inside a container such as Tomcat or Jetty.
Views can be written with a Kotlin HTML DSL or with JVM template engines, among them FreeMarker, Velocity, Mustache, Thymeleaf, Pebble and JTE. Authentication covers LDAP and OpenID Connect.
New projects come from the web-based project generator, and the core dependency is io.ktor:ktor-server-core, resolved from Maven Central through Gradle or Maven. JetBrains supports and develops the framework.
