Problem

In Shiny for R, setting session$allowReconnect(TRUE) enables reconnection behavior to existing or new sessions whenever shiny server disconnects. I don't believe this exists at the moment for Shiny for Python.

On the Javascript console on a Shiny for Python app, running Shiny.shinyapp.$socket.close() then Shiny.shinyapp.reconnect() does seem to produce this behavior, but Shiny.shinyapp.allowReconnect = false and I'm unsure how to enable.

Solution

I would like the ability to set this from Python using the session object.

session.allow_reconnect(True)

and this would cause Shiny to behave similar to when it is enabled in R.
