We’re going to be using the Shiny application from the 2023 Shiny in production posit::conf() workshop.1 The application demonstrated in this workshop–brickapp–is an app-package with various versions in the Git branches (similar to the sap package). We’re going to be using a slightly modified version of the application stored in the profiledemo branch.2 brickapp was built using the golem framework (we’ll cover golem in Chapter 23), and a folder tree of it’s structure is below:

I’ve chosen this example to illustrate the gander package because

  1. The accompanying GitHub repo for the application.↩︎

  2. The prediction modules/functionality has been removed from the version we’re using. If you’d like to see the full app, check the Github Repo.↩︎
