ahooksahooks is a high-quality, reliable, and comprehensive React Hooks library developed by Ant Group. It aims to encapsulate common and complex logic into reusable hooks, significantly improving development efficiency and code quality in React applications.
Purpose and Benefits:
1. Encapsulation of Complex Logic: It abstracts away common patterns and complex logic, such as form validation, state management, asynchronous data fetching, UI interactions (e.g., debouncing, throttling, drag and drop), and performance optimizations (e.g., memoization, throttling effects).
2. Improved Developer Experience (DX): Developers can focus more on business logic rather than reimplementing common utility functions or intricate state management patterns. It provides a consistent API for various functionalities.
3. Reliability and Stability: Being developed and maintained by a large organization like Ant Group, ahooks undergoes rigorous testing and is used in production environments, ensuring its stability and reliability.
4. Performance Optimization: Many hooks come with built-in performance considerations, such as `useDebounce`, `useThrottle`, and `useMemoizedFn`, which help in building more performant applications.
5. Comprehensive Set of Hooks: ahooks offers a wide array of hooks categorized into various domains:
* State Hooks: `useToggle`, `useBoolean`, `useSetState`, `useMap`, `usePrevious`, etc.
* Effect Hooks: `useDebounceEffect`, `useThrottleEffect`, `useUpdateEffect`, `useMount`, `useUnmount`, etc.
* Async Hooks: `useRequest` (for data fetching), `useAsyncEffect`, `useAsyncFn`, etc.
* DOM Hooks: `useClickAway`, `useEventListener`, `useFullscreen`, `useInViewport`, `useLongPress`, `useMouse`, `useScroll`, etc.
* UI Hooks: `useVirtualList`, `useFormTable`, `usePopup`, `useCountDown`, etc.
* Advanced Hooks: `useFusionTable`, `useAntdTable` (integrations with Ant Design components), `usePagination`, etc.
Installation:
```bash
npm install ahooks
# or
yarn add ahooks
```
ahooks is an essential toolkit for any serious React developer looking to streamline development, reduce boilerplate, and build robust, high-performance applications with ease.
Example Code
import React from 'react';
import { useRequest } from 'ahooks';
// A mock service function that simulates an API call
const getUserProfile = async (userId) => {
console.log(`Fetching user profile for ID: ${userId}`);
return new Promise((resolve) => {
setTimeout(() => {
if (userId === 1) {
resolve({ id: 1, name: 'Alice', email: 'alice@example.com' });
} else if (userId === 2) {
resolve({ id: 2, name: 'Bob', email: 'bob@example.com' });
} else {
throw new Error('User not found');
}
}, 1500);
});
};
function UserProfileViewer() {
const userId = 1; // Example user ID
const { data, loading, error, run, refresh } = useRequest(
() => getUserProfile(userId), // The service function to execute
{
// Options for useRequest hook
manual: true, // Set to true to prevent immediate execution on mount
onSuccess: (result, params) => {
console.log('Successfully fetched user profile:', result);
// You can do something with the data here, e.g., show a toast
},
onError: (err, params) => {
console.error('Failed to fetch user profile:', err.message);
// Handle error, e.g., show an error message to the user
},
// refreshDeps: [userId] // If userId changed, the request would re-run automatically (if manual is false)
}
);
