Feature Request: A viewer in the REPL

[gitdemont]

Hello,

Would it be possible to have a viewer in the REPL (e.g. an iframe) listening to current in-browser session ?
So as for instance to run shiny apps alike https://github.com/georgestagg/shiny-standalone-webr-demo, display DT::datatable, ... html.

At the very least, we should support View() for showing data frames in a cell-based format. Also related to #295.

Hi @georgestagg ,

I just tried your #449 PR. And it's 🚀 !

I tested a basic shiny::runGadget but without success (I was too much in a hurry)
console says it's listening to url:port but access to url:port is denied
in addition, REPL is blocked and webr.r-wasm.org/latest needs to be refreshed

However, I was able to display several widgets (from visNetwork and DT) directly in the REPL 👍 .

Thanks a lot !

Closing, with #449 webR should now cover most requirements for viewing HTMLwidgets and UI elements. Shiny and shiny::runGadget is a harder problem, due to the requirement of communication with the shiny server.

I think I would consider displaying Shiny apps and gadgets out of scope for the webR application. For that use case, one should use https://shinylive.io/r/, which already has the infrastructure in place to handle the Shiny server under Wasm.

Thanks for the addition !
