implement back-end in real time

Hello people from the forum, I wanted to ask a question, is it possible to use the gnu version of gantt and connect it with a real-time back-end? I am using the version of node.js, which back-end system would you recommend to be able to connect the gantt with the back?
thank you so much

Hello Augusto,
The regular Gantt version is the Web version. You can run it in the browser even without showing it. But you cannot run it in the Node.js environment as Gantt needs the window object.
There is the Gantt version for Node.js, but it is not free:
https://docs.dhtmlx.com/gantt/desktop__using_gantt_on_server.html

If you want to use Gantt only on the client-side, it should work correctly there.

I cannot recommend the backends. But for it to work correctly with Gantt, it needs to work with the REST API.
You can read the following article about integrating Gantt with the server-side:
https://docs.dhtmlx.com/gantt/desktop__server_side.html

And just in case, here is the link to the guide for adding Gantt to the Node.js environment:
