react-use

react-use is a comprehensive collection of essential React Hooks that aims to simplify common UI patterns, state management, and side effects in React applications. It provides a wide array of hooks for various purposes, including state management, UI interactions, animations, sensor data, network status, lifecycle management, and more. By leveraging React's built-in Hook API, react-use helps developers write cleaner, more readable, and reusable code, reducing the need for boilerplate and complex custom hook implementations.

Key features and benefits of react-use:

1. Extensive Collection: It offers over 70 hooks, covering a vast range of functionalities from simple state toggling (`useToggle`) to advanced sensor data (`useGeolocation`, `useBattery`) and UI measurements (`useMeasure`, `useWindowSize`).
2. Reduces Boilerplate: Many common patterns that would otherwise require multiple `useState`, `useEffect`, or `useCallback` hooks can be encapsulated into a single, easy-to-use hook from `react-use`.
3. Improved Readability and Reusability: By abstracting complex logic into custom hooks, components become more focused on their rendering logic, making them easier to understand and maintain. These hooks can also be reused across different components.
4. Well-tested and Maintained: The library is actively maintained and well-tested, ensuring reliability and compatibility with the latest React versions.
5. Performance Optimization: Many hooks are designed with performance in mind, often memoizing values or debouncing/throttling events internally.

Installation:
`npm install react-use` or `yarn add react-use`

Example categories of hooks include:
* State Hooks: `useToggle`, `useLocalStorage`, `usePrevious`, `useSetState`
* UI Hooks: `useClickAway`, `useHover`, `useFullscreen`, `useMeasure`
* Animation Hooks: `useSpring`, `useTween`
* Lifecycle Hooks: `useMount`, `useUnmount`, `useUpdateEffect`
* Sensors Hooks: `useGeolocation`, `useBattery`, `useWindowScroll`, `useWindowSize`
* Miscellaneous Hooks: `useDebounce`, `useThrottle`, `useInterval`, `useTimeout`

react-use is an invaluable toolkit for any React developer looking to streamline development and enhance the functionality of their applications with battle-tested and efficient custom hooks.

import React, { useRef } from 'react';
import { useToggle, useMeasure, useWindowSize } from 'react-use';

function ReactUseExample() {
  // 1. useToggle: Manages a boolean state with a toggle function
  const [isOn, toggle] = useToggle(false);

  // 2. useMeasure: Measures the dimensions of a DOM element
  const ref = useRef(null);
  const { width, height } = useMeasure(ref);

  // 3. useWindowSize: Provides current window dimensions
  const { width: windowWidth, height: windowHeight } = useWindowSize();
