## What it is
A curated collection of Shiny tips, tricks, and design patterns by Dean Attali, with each tip accompanied by a complete functional Shiny app demonstrating a non-trivial task. It covers common problems like loading animations, hiding tabs, URL-based input pre-population, and splitting app code across files.

## Use cases
- show a loading spinner while a shiny plot recalculates
- pre-populate shiny inputs from url parameters
- split a large shiny app across multiple files
- hide or disable shiny inputs programmatically
- show custom error messages when shiny outputs fail
- automatically stop a shiny app when the browser tab closes
- learn advanced shiny design patterns

## When to choose
- you build R Shiny apps and hit common UI or UX problems
- you want working example apps demonstrating non-trivial Shiny techniques
- you are learning to push Shiny beyond basic usage

## When to avoid
- you need a production library or package rather than example code
- you are not using R or Shiny
- you need officially supported documentation instead of community tips
