Shows a working Shiny app architecture that uses modules to replace duplicated UI widgets and messy reactive wiring, with one example deployed as the Ames housing data Explorer on the Shiny gallery. Explains using modules to handle persistent session state, dynamic UI and HPC integration, documents clear inputs/return lists, and demonstrates nesting modules. Warns against the reactiveValues kitchen sink hidden‑state anti‑pattern, covers when to pass static vs reactive args and the common parentheses gotcha.
