Javalin is a free and open-source software web application framework that started as a fork of the web framework Spark[1]. Like Spark, Javalin is inspired by Sinatra, and follows a purely programmatic approach to building web-applications: "You don't need to extend anything, there are no @Annotations, no reflection, no other magic; just code" [2]. As of version 2.6, the framework supports most modern features, such as HTTP2, WebSockets, asynchronous requests and server-sent events[3][4].
Hello World Example[edit]
import io.javalin.Javalin
fun main(args: Array<String>) {
val app = Javalin.create().start(7000)
app.get("/") { ctx -> ctx.result("Hello World") }
}
