When paired with a server-side service to gain access to data -storage and server-side business logic, client-side applications can be -considered "fat clients", in comparison to the "thin client" approach of the -server-side Vaadin applications. The services can use the same back-end services -as server-side Vaadin applications. Fat clients are useful for a range of -purposes when you have a need for highly responsive UI logic, such as for games -or for serving a huge number of clients with possibly stateless server-side -code. - -[[figure.clientsideapp.overview.architecture]] -.Client-Side Application Architecture -image::img/clientsideapp-architecture-hi.png[] - -A client-side application is defined as a __module__, which has an -__entry-point__ class. Its [methodname]#onModuleLoad()# method is executed when -the JavaScript of the compiled module is loaded in the browser. - -Consider the following client-side application: - - ----- -public class HelloWorld implements EntryPoint { - @Override - public void onModuleLoad() { - RootPanel.get().add(new Label("Hello, world!")); - } -} ----- - -The user interface of a client-side application is built under a HTML __root -element__, which can be accessed by [methodname]#RootPanel.get()#. The purpose -and use of the entry-point is documented in more detail in -<<dummy/../../../framework/clientsideapp/clientsideapp-entrypoint#clientsideapp.entrypoint,"Client-Side -Module Entry-Point">>. The user interface is built from __widgets__ -hierarchically, just like with server-side Vaadin UIs. The built-in widgets and -their relationships are catalogued in -<<dummy/../../../framework/clientsidewidgets/clientsidewidgets-overview.asciidoc#clientsidewidgets.overview,"Client-Side -Widgets">>. You can also use many of the widgets in Vaadin add-ons that have -them, or make your own. - -A client-side module is defined in a __module descriptor__, as described in -<<dummy/../../../framework/clientside/clientside-module#clientside.module,"Client-Side -Module Descriptor">>. A module is compiled from Java to JavaScript using the -Vaadin Compiler, of which use was described in -<<dummy/../../../framework/clientside/clientside-compiling#clientside.compiling,"Compiling -a Client-Side Module">>. The -<<dummy/../../../framework/clientsideapp/clientsideapp-compiling#clientsideapp.compiling,"Compiling -and Running a Client-Side Application">> in this chapter gives further -information about compiling client-side applications.

An off-line mode can persist data -in a local store in the browser, thereby avoiding the need for server-side -storage, and transmit the data to the server when the connection is again -available.
