D2Bridge Framework

D2Bridge Framework is Delphi and Lazarus for Web Your Delphi or Lazarus code compiling for the Web using the Delphi and Lazarus way, synchronous on the Web. D2Bridge is Open Source. D2Bridge is the framework that allows you to code normally in Delphi while maintaining your code synchronously, allowing you to focus on your Delphi project as you always have and compile for the Web Generates responsive HTML code compatible with Bootstrap 5 and the latest Web technologies It already comes with Templates and its web interface can be different from your VCL project without changing its code No additional components are necessary when exporting to the Web. D2Bridge recognizes and intercepts your visual components You can compile your application for Desktop and Web using the same code and the same interface that you already have in your project When compiling your application for the Web, you can choose between 3 very lightweight and powerful Web Servers (Console, Compact and Full) From a simple 'MessageDlg' response to a ShowModal or Timer, everything works on the Web in the same way as on the Desktop With D2Bridge Framework, your application has native support for multiple languages, allowing you to easily write your application for the world to see. You can use D2Bridge Framework normally for any purpose, including projects for commercial purposes
