Positron doesn't include run app button in server.R

[jsinnett]

I'm migrating from RStudio to Positron and working to configure my workspace / Positron settings. Combing through the docs it looks like Positron will recognize the app.R file and populate the Run App button in the top right of the panel.

In my case, I'm not using an app.R file. Instead, I'm using a multi file structured approach with ui.R / server.R and have a global.R to load packages and set other key variables.

When opening a server.R file in Positron, the run app button does not populate. I know I can use shiny::runApp however, it'd be nice to see the same functionality.

Does this functionality exist and I'm just not seeing it or setting it up properly?

Do you have the Shiny extension installed? We do not currently include that one by default:

Yes, I do have it installed

Great! Can you ask about this feature request on the repo for the Shiny extension?

The behavior for when/how the Shiny "Run App" button gets contributed is controlled by that extension.
