package org.jgrapes.webconsole.examples.consoleapp
This package provides a sample web console configuration which can be used for testing and demonstration purposes.

It provides a web console with HTTP (port 8888) and HTTPS (port 8443) access.

Component tree

An instance of the ConsoleApp serves as root of the component tree.

Application hierarchy

The child components of the ConsoleApp instance are the components related to the network connection, a SocketServer for the plain text connection and an SslCodec with another SocketServer as its child for the encrypted connection. In addition there is an HttpServer that handles the I/O events and converts them to HTTP level events.

The HttpServer has as children all components that handle HTTP requests (and generate the responses). Most notably the VueJsConsoleWeblet that handles the resource requests related to the main page and generates the provider and conlet related events.

Attached to the WebConsole, we finally have the components BrowserLocalBackedKVStore and KVStoreBasedConsolePolicy and the ComponentCollectors for page resource providers and conlets. The collectors pick up the page providers and web conlets in the classpath and attach them to themselves.

Channel usage

In order to avoid unnecessary handler invocations, the components use different channels for different event domains, as shown in the next picture.

Channel usage

The only component interested in events from the SocketServer for the secure connection is the SslCodec (end the events that the latter generates are only intended for the former). Therefore these two use a channel of their own (the SocketServer instance for simplicity).

Input from the socket server for plain connections and input from the SSlCodec is handled solemnly by the HttpServer. So these three use their own channel. Again, this also applies to the reverse direction, i.e. output events generated by the HttpServer are handled by the SocketServer or the SslCodec that has created the subchannel on which the event (as a response) is fired.

HTTP application layer events that are generated by the HttpServer are fired on the httpApplication channel which is used by the components interested in theses events.

Finally, we use the WebConsole component as channel for all events related to the portal application.
