Experimental Netty-based application/web framework.

An example application can be seen here.

Should I use this?

Probably not! It's still incredibly early-stage -- everything's versioned at 0.0.1 for a reason, after all~ -- and so there's all sorts of instabilities, weirdness, etc. that you probably don't want to deal with.

Components

• autumn-example: Example application.
• autumn-application: Application bootstrap.
• autumn-config: HJSON-based configuration.
• autumn-di: Dependency injection framework.
• autumn-data: Database access layer.
• autumn-json: JSON helper library.
• autumn-web: Web framework.

What does work

• JVM boot to usable API in ~500ms
• Runs with 32MB of heap RAM or less
• Runtime DI + modularisation via components
• Component dependencies
• JSON
• Web server
• HJSON-based autoconfig
• Object-mapping database manipulation via PostgreSQL JSONB.

What doesn't work

• Multipart
• Websockets
• HTTP/2 (dealing with SSL is a hairy problem)
• Globbing routes

Build an API in 30 seconds

public class Readme {
    public static void main(String[] args) {
        AutumnApplication.run();
    }

    @Route(method = HttpMethod.GET, path = "/hello/:name")
    public Response hello(Request req) {
        return Response.create().body("henlo " + req.params().get("name") + '!');
    }
}

Modularise with components

@Component
public class HelloComponent {
    public String sayHello(String name) {
        return "henlo " + name + "!";
    }
}

public class Readme {
    @Inject
    private HelloComponent hello;

    public static void main(String[] args) {
        AutumnApplication.run();
    }

    @Route(method = HttpMethod.GET, path = "/hello/:name")
    public Response hello(Request req) {
        return Response.create().body(hello.sayHello(req.params().get("name")));
    }
}

Singleton components for ex. databases

@Component
@Singleton
public class SingletonComponent {
    public String sayHello(String name) {
        return "henlo " + name + "!";
    }
}

public class Readme {
    @Inject
    private SingletonComponent singleton;

    public static void main(String[] args) {
        AutumnApplication.run();
    }

    @Route(method = HttpMethod.GET, path = "/hello/:name")
    public Response hello(Request req) {
        return Response.create().body(singleton.sayHello(req.params().get("name")));
    }
}
