Welcome to TMS WEB Core. TMS WEB Core is the foundation of an exciting new and modern way for creating web client applications from Delphi using RAD development methodology and using a component-based framework.

Scope and architecture

TMS WEB Core is based on compiling Delphi UI code to JavaScript and creating this way what is called Single-Page-Applications. The terminology "page" should not be confused with forms that Delphi developers are used to. A TMS WEB Core application can contain multiple forms. These multiple forms will be hosted in a JavaScript application a web browser user can navigate to via a single page URL. We will further refer to TMS WEB Core applications as web client applications. This means applications running as JavaScript code in the browser client (left). The web client application will typically communicate with a server or servers for working with data or other services (right). The TMS WEB Core web client application is open to work with different server technologies. This includes but is not limited to TMS XData, Embarcadero RAD Server, node.js, ASP.NET Core microservices. The typical technology used for this communication is via HTTP REST APIs.

More information about using TMS XData as a backend for TMS WEB Core web client applications can be found at:

TMS XData provides 3 components to make it easier to consume a TMS XData REST API:
