Introduction

ActiveJ is a fully-featured alternative Java platform built from the ground up as a replacement of Spring, Spark, Quarkus, Micronauts, and other solutions. It is minimalistic, boilerplate-free, and incomparably faster, which is proven by benchmarks. ActiveJ has very few third-party dependencies, yet features a full stack of technologies with an efficient async programming model and a powerful DI library ActiveInject

Quick start

Insert this snippet to your terminal...

mvn archetype:generate -DarchetypeGroupId=io.activej -DarchetypeArtifactId=archetype-http -DarchetypeVersion=3.0.1

... and open the project in your favourite IDE. Then, build the application and run it. Open your browser on localhost:8080 to see the "Hello World" message.

Fully-featured embedded web application server with Dependency Injection:

public final class HttpHelloWorldExample 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); 
    }
}

Some technical details regarding the above example:

• Features a JAR file size of only 1.4 MB. In comparison, a minimal Spring web app size is approximately 17 MB.
• The cold start time is 0.65 sec.
• The ActiveInject DI library which is used, is 5.5 times faster than Guice and hundreds of times faster than Spring.
