## What it is
React Idle Timer is a React hook and component for detecting user activity and idle states in web applications. It provides configurable idle timeouts, debounced or throttled activity callbacks, a built-in 'are you still there' confirm prompt, cross-tab synchronization via BroadcastChannel, and WebWorker-offloaded timers to avoid background tab throttling.

## Use cases
- log out inactive users in a react app
- detect when a user goes idle and becomes active again
- show an 'are you still there' prompt with a countdown before session timeout
- sync idle state across multiple browser tabs
- track and react to user activity events like mouse and keyboard input
- keep timers accurate when the tab is in the background

## When to choose
- you are building a React app and need reliable idle/active presence detection
- you need cross-tab or multi-window synchronization with leader election
- you want a built-in confirm prompt flow before firing the idle event
- you need a battle-tested solution with high download volume, full test coverage, and TypeScript support

## When to avoid
- your project is not React-based (e.g., Vue, Angular, vanilla JS) since the API is React-specific
- you only need a simple one-tab timeout that a plain setTimeout with event listeners can cover
- you need idle detection on a server or in non-browser environments
