WebR and shinylive examples
This website, built with quarto and hosted on github pages, showcases both the WebR and shinylive quarto extensions.
The WebR page shows an example of an interactive tutorial in which you can run R code and see the results directly in the browser without being connected to an R session on a remote server.
The shinylive page shows how a live shiny app can run and be edited in the browser via WebR.
