Summary:
In this video, we use the Positron IDE (Public Beta) to create and render Shiny applications in both R and Python.
In short, you need to install the Shiny VS extension by going to the extensions tab, searching for `shiny` (the non-deprecated one), and then pressing install on the Shiny extension. Alternatively, you can directly go to the extension page on OpenVSX and install it there:
open-vsx.org/extension/posit/...
Once the extension is installed, the R and Python document file types will gain a new option to "Run Shiny App" under the play button. Please make sure to name your Shiny app files appropriate, e.g. app.R and app.py. Avoid placing the shiny application in your home directory, e.g. ~/, on macOS to avoid a permissions issue.
The Shiny for R app was built using the different UI/Server components here:
shiny.posit.co/r/getstarted/s...
The Shiny for Python App was built using the first example here:
shiny.posit.co/py/docs/overvi...

Not working properly, error no xxxx file found

[@thecoatlessprofessor7674]

Can you provide a bit more details on the error? Is the error associated with the Shiny for Python or Shiny for R demo? Did you accidentally save the `app.R`/`app.py` into the home directory, e.g. `~/`, instead of into a subfolder like `~/Documents` or `~/Desktop`?

@@thecoatlessprofessor7674 It was downloaded from positron itself, but in some other videos it explains with GitHub installation, It worked then. Thank you for your prompt reply.
