Workshop topics

[rpodcast]

@mthomas-ketchbrook Here's a list of proposed topics / ideas to cover during the workshop we discussed. Feel free to add anything I missed!

• Setting up an application with {golem}
• Modules
• Optimization for speed and handling large user load
• Importance of testing business logic and quick intro to {shinytest2}
• Deployment on Posit Connect and alternative deployment strategies such as platform services utilizing container versions of app
• Profiling code with {profvis}
• Placement of objects within a Shiny app codebase, how that determines what is shared across sessions of an app (see example snippet below)
• Handling multiple upstream/downstream processes interacting with the application
• Having the app do as little as possible (i.e. offloading time-consuming and resource-intensive processes to other services such as a {plumber} API

# First place
my_object_here <- something()

server <- function() {
  # second place
  my_object_here <- something()

  output$plot <- renderPlot({
     # third place
     my_object_here <- something()

Concepts we can talk about:

• Effective use of data (not always bringing in all data upfront can cause performance issues)

Parquet for data files on S3 storage
