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")));
}
}
