It is a known fact that Web applications are replacing the old desktop applications. A Web application is accessible from any modern web browser without deploying anything to the client device, it is much easier to update, there are many advantages. But achieving the same user interface and responsiveness provided by a desktop application on the Web was almost impossible or unfeasible until a few years ago.
The first attempt to bring the desktop user experience to the Web, Rich Internet Application (RIA), required the installation of a local run-time framework or plug-in on the client computer. Microsoft Silverlight, Microsoft WPF XAML Browser Applications, Flash, are some examples of this generation. Most of these technologies are now deprecated.
uniGUI is a Web application framework capable of creating and deploying stateful Single-Page Applications.
What makes uniGUI unique is that it looks natural to any Delphi user, as simple as using any other component library in the Delphi marketplace. Behind the scenes, many things must happen to make the SPA work.
It is possible to create a uniGUI SPA with its own Web HTTP Server, or just an ISAPI module which will need an ISAPI Handler for answering the requests from the host Web server. But for any SPA, it is necessary to handle some typical tasks as part of the uniGUI Web Application framework:
6.Automatic handling of AJAX calls between each client and the server
A uniGUI application can be considered as a standard Delphi VCL application which uses a Web browser as its presentation layer. uniGUI enables developers to create, design, and debug their Delphi applications as they develop regular desktop applications, and allows them to choose any of the available options for Web deployment. This means that a Delphi developer with little knowledge about Web technologies can start developing a Web application using uniGUI out of the box.
