Package dev.relism.flash.extension

Interface FlashApplication

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface FlashApplication

One application's complete contribution to a FlashApp — its routes, extensions and services — expressed independently of which port or configuration it runs on.

Optional. The fluent form keeps working exactly as before; this interface exists so the same application can be created more than once, on more than one port:

 public final class BlogApp implements FlashApplication {
     @Override public void configure(FlashApp app) {
         app.install(new JacksonExtension());
         app.mount("/api", scope -> scope.scan("dev.blog.api"));
         app.ws("/live", new FeedSocket());
     }
 }

 // production
 FlashApp.create(8080).apply(new BlogApp()).startAndBlock();
 

It takes FlashApp rather than FlashRegistrar deliberately: ws and mount live on FlashApp, and an application that could not register a WebSocket route or a mounted namespace would be a half-application.

Being a @FunctionalInterface, a lambda and a named class are the same thing here — app -> app.get("/ping", ...) is as valid as new BlogApp().

void	configure(FlashApp app)	Registers this application onto app.

Method Details

configure

void configure(FlashApp app)

Registers this application onto app. Called immediately by FlashApp.apply(dev.relism.flash.extension.FlashApplication), so the service graph is still open for declarations (app.ctx().supply(...)) and the listener is already bound (app.port()).
