If you are interested to explore Shiny application further then you can play with examples from Posit and some from a Stat instructor.
Distributing and Running Shiny Apps¶
You can use nbgitpuller to distribute a shiny application. Specify a URL of /shiny. You can also specify the full path to the shiny app. For example if the application exists in course-repo/app1, the nbgitpuller custom URL would be shiny/course-repo/app1.
Users can also run Shiny from the JupyterLab launcher. This will display a shiny file browser.
