Java framework for modern web, cloud, high-load, and microservices solutions

A full-featured, modern Java platform built from the ground up as an alternative to Spring/Micronauts/Netty/Jetty. It is designed to be self-sufficient (no third-party dependencies), simple, lightweight and provides competitive performance. It consists of a number of libraries, from dependency injection and high-performance asynchronous I/O (inspired by Node.js), to application servers and big data solutions

class Main extends HttpServerLauncher {  @Provides  AsyncServlet servlet() {    return request -> HttpResponse.ok200()      .withPlainText("Hello world");  }    public static void main(String[] args) throws Exception {    Launcher launcher = new HttpHelloWorldExample();    launcher.launch(args);  }}
