We're preparing tutorials and you will see that it's possible to do it very easily :)
Of course, we have some premium components (under the MIT license) that are hidden. Also you can create Flow components directly in Flow, that's amazing!
You could check Budibase, I build a simple customer portal for one of our customers with it.
Now I build a "real" project with Supabase for the backend and Vue.js + Quasar for the frontend. And that comes damn near this vision. Only a dragn'n'drop GUI editor is missing, but with the near zero reload-times of modern vue.js with Vite editing the GUI in code comes near.
There are of course several "frameworks" for Delphi, that offer "building webapps with Delphi and then compiling it to JS & Javascript, but I decided not to go into this direction, because Delphi paradigmns are no good fit for the web and I doubt I'm gonna find anyone else if I'm going to need more manpower.
For Delphi:
* TMS Webcore https://www.tmssoftware.com/site/tmswebcore.asp
* uniGUI http://www.unigui.com/
Delphi Inspired Pascal IDE for the Web:
* Elevate Web Builder https://www.elevatesoft.com/home
* Quartex Pascal https://quartexdeveloper.com/
* Smart Mobile Studio https://smartmobilestudio.com/
I've been giving Storybook[1] a shot to solve this problem. Works pretty well from scratch on new projects, but importing existing Vue components, especially from large third party component libraries, has proven a little onerous so far for me. But maybe you'll have a little more luck with Vue/Quasar.
Would love to hear what you think!
Unfortunately, I still have not found that yet.
