Is `shiny-server` able to run apps built with Dash, Flask, etc ? #575

avhz commented 3 months ago

We have shiny-server set up to run R Shiny and Python Shiny apps, however I am interested to know if it can also serve Dash apps, for example.

The "drag-and-drop" into /srv/shiny-server provides a tonne of convenience and it would be great if there was a way to do the same with a Dash or Flask app too.

I have tried a minimal Dash app, but get "Internal Server Error" at the URL, because I assume SockJSAdapter.py is not able to pick the app up since it is not of the form app = App(ui, server).

Any advice would be greatly appreciated !

No, sorry. Shiny Server is only designed for Shiny. Our enterprise hosting server, Posit Connect, and cloud hosting server Posit Connect Cloud, work with additional frameworks including Dash and Flash.

I will note that Posit Connect uses a CLI command to deploy apps, and Posit Connect Cloud uses Git push-to-deploy. People generally find those options more convenient than /srv/shiny-server though, not less, since package dependency installation/isolation is handled automatically.
