Support for Quarto Shiny dashboards

[bisacciamd]

In recent months there's been significant development in Quarto Dashboards, and Shinylive integration in Quarto. However, at present, it is not possible to integrate Shinylive specifically within a Quarto Dashboard running a Shiny application.

As Quarto dashboards use a somewhat similar structure to standard Shiny apps, I think integration of this feature in Shinylive would be feasible & extend Shinylive applicability and use cases.

Note

Some background for the googler, this is related to a question @bisacciamd asked on StackOverflow and ended up in my inbox, which was redirected here. The relevant SO question:

A way for shinylive integration for serverless Quarto R Dashboard?

@bisacciamd This repository is related to a tutorial using Shinylive within Quarto. The issue ticket you typed up is more of a feature request for the Shinylive for R project. I would suggest placing the request at either:

• Quarto Shinylive Extension: https://github.com/quarto-ext/shinylive/issues/
• R shinylive package to export pre-existing apps: https://github.com/posit-dev/r-shinylive/issues/

In the interim, I probably would encourage you to set up a Shiny App that uses the {bslib} library to deliver a shiny dashboard:

https://rstudio.github.io/bslib/articles/dashboards/index.html

For instance, consider the following myapp/app.R:

library(shiny)
library(bslib)

ui <- page_sidebar(
  title = "My dashboard",
  sidebar = "Sidebar",
  "Main content area"
)

server <- function(input, output) {
  # code here
}

shinyApp(ui, server)

This would allow you to then directly convert the shiny app to shinylive via:

# Install shinylive from CRAN
install.packages("shinylive")

# Convert the shiny app in `myapp` to a shinylive app available in `site/`
shinylive::export("myapp", "site")

# Check locally the dashboard
httpuv::runStaticServer("site/")

Publish the site/ files on GitHub pages to fully get a working app. I'll probably throw together a quick deployment guide based on the above skeleton later tonight.

@bisacciamd sorry for the delay; it's been hectic.

So, I've ported over the example Earthquake dashboard that Quarto Dashboard used to a Shiny Dashboard powered by bslib. From there, I've converted it into an r shinylive dashboard app.

You can see the repository over here:

https://github.com/coatless-tutorials/r-shinylive-dashboard-app

The app should appear here (warning, large file size on mobile):

Wow - thank you very much @coatless, this is impressive — I'll look into it and try my luck.
