How to dynamically display newly generated VTK files and handle multiple URLs in Trame?

[Hao1027]

Hello,

I am currently working on a project where new VTK files are generated continuously, and I need to display them on the frontend using Trame. I would like to know how to dynamically specify which VTK file to display as new files are created, rather than being limited to a fixed set of files.

Additionally, I would like to know if there is a way to handle routing in Trame, so that I can have multiple URLs to display different VTK files. For example, I want to be able to access different VTK files via different URLs within the same server instance.

Any guidance or examples on how to achieve these functionalities would be greatly appreciated.

Thank you!

Best regards

trame-router allow you to create different views for different urls. But it seems that you want the same view that can load different files. Also you talk about server but not session, so I'm guessing that you are ok with 1 server that has 1 viz process per loaded file / browser tab.

If that is the case, this would be a standard docker setup where you don't need trame router. You just need your trame app to expect a command line argument for the file to load and just configure the launcher to use the URL parameter for it.

Thank you very much, I appreciate the time and effort.

My vtk files keep generating continuously. Is there a way to dynamically add sessions without restarting the server, or can the client load vtk files on the front-end webpage by themselves?

I guess, I'm getting lost on what you are trying to do. Maybe we don't have the same definition of session or server. Either way, it is pretty straightforward to dynamically load and display vtk files either within the same session or in a new one.
