课程名称：通过示例掌握 React Hooks 课程概述： “通过示例掌握 React Hooks”是一个旨在帮助开发者深入了解 React 17、18 和 19 中所有 Hooks 的课程。如果您已经熟悉 React 的基础知识，想进一步探索其核心功能，这门课程将非常适合您！我们将通过实际的、真实世界的示例来揭示 React 所有内置 Hooks 的神秘面纱，这些 Hooks 是现代 React 开发的基础，使得您能够构建动态、高效且易于维护的应用程序。 您将学习到： - `useState`：在功能组件中有效管理状态。 - `useEffect`：处理副作用，如数据获取、更新 DOM 等。 - `useRef`：处理可变引用并直接与 DOM 元素交互。 - `useContext`：在应用程序中共享数据而不需要层层传递 props。 - `useReducer`：通过 reducer 函数和初始状态管理复杂状态逻辑。 - `useMemo`：缓存昂贵的计算结果，只有在依赖项改变时才返回新结果。 - `useCallback`：缓存函数，只有在依赖项改变时才返回相同实例，以优化子组件性能。 - `useImperativeHandle`：自定义父组件访问子组件 ref 时暴露的实例值。 - `useLayoutEffect`：在 DOM 修改后但在浏览器绘制之前同步运行，确保布局更新立即应用。 对于 React 18 的 Hooks： - `useId`：为组件生成唯一 ID，用于确保无障碍和表单元素的一致标识符。 - `useTransition`：标记状态更新为非阻塞过渡，提高 UI 响应性。 - `useDeferredValue`：在不太紧急的更新完成之前延迟更新值。 - `useSyncExternalStore`：确保外部存储的一致状态快照。 - `useInsertionEffect`：用于在 React 对 DOM 进行更改之前注入样式或执行 DOM 修改。 对于新推出的 React 19 的 Hooks： - `useActionState`：在 React 服务器组件中管理服务器端动作的状态。 - `useFormStatus`：提供表单的当前状态，包括提交状态和错误处理。 **自定义 Hooks** 学习如何在 React 中构建自定义 Hooks，包括： - API Axios：如何使用自定义 Hook 通过流行的 Axios 库与 API 进行通信。 - 乐观更新：如何使网站看起来表现更快。 - 防抖：如何防抖网站输入。 学习方式： 本课程强调通过实践学习。通过实际示例，您将探索在真实开发项目中可能遇到的典型场景，如： - 管理表单输入与状态。 - 从 API 获取和显示数据。 - 跨渲染保持引用持久性。 - 创建并消费全局状态管理的上下文。 课程目标： 通过课程结束，您不仅能从概念上理解这些 Hooks，还能自信地在 React 应用程序中解决实际问题。该课程非常适合那些具备基础 React 知识并希望学习如何在功能组件中使用 Hooks 的初学者。 无论您是希望巩固 React 知识还是为更高级的主题做准备，“通过示例掌握 React Hooks”将使您拥有构建强大、现代化 React 应用程序的技能。现在就注册，开始掌握 React 17、18 和 19 的 Hooks 吧！
Master React Hooks by Example: Learn all the Hooks in React 17, 18 and 19!Are you ready to take your React skills to the next level? If you're familiar with React's basics and want to dive deeper into its core functionality, "Master React Hooks by Example" is the perfect course for you!In this developer-friendly course, we'll demystify all of React's built in hooks by exploring them through practical, real-world examples. These hooks are the foundation of modern React development, empowering you to build dynamic, efficient, and maintainable applications.What You'll LearnuseState: Manage state effectively within functional components.useEffect: Handle side effects like fetching data, updating the DOM, and more.useRef: Work with mutable references and interact directly with DOM elements.useContext: Share data across your app without prop drilling.useReducer: Manages complex state logic by taking a reducer function and an initial state, returning the current state and a dispatch function to update ituseMemo: memoizes expensive calculations, returning a cached result only when its dependencies changeuseCallback: memoizes a function, returning the same instance unless its dependencies change, to optimize performance in child componentsuseImperativeHandle: customizes the instance value exposed when a parent component accesses a child component's ref.useLayoutEffect: runs synchronously after DOM mutations but before the browser paints, ensuring layout updates are applied immediatelyREACT 18 HooksuseId: generates a unique ID for components, for consistent identifiers for accessibility and form elementsuseTransition: marks state updates as non-blocking transitions, improving UI responsiveness during expensive state changesuseDeferredValue: defers updating a value until less urgent updates are finished, improving performance by preventing UI lag during expensive rendersuseSyncExternalStore: ensures a consistent state snapshot from external stores, supporting concurrent rendering and server-side renderinguseInsertionEffect: is used for injecting styles or performing DOM mutations before React makes changes to the DOM, ensuring minimal flickering or inconsistencies.REACT 19 Hooks (New!)useActionState: manages the state of server-side actions, such as form submissions or data-fetching, within React Server Components.useFormStatus: provides the current status of a form, including submission state and error handling, typically used in React Server Components**CUSTOM HOOKS** Learn how to build custom hooks in React including:API Axios: how to use a custom hook to communicate with API using the popular Axios library Optimistic Updates: how to make a website appear to be perform FASTER with Optimistic UpdatingDebouncing: How to debounce website inputsAnd Much More!How You'll LearnThis course emphasizes learning by doing. Through hands-on examples, you'll explore typical scenarios you're likely to encounter in real development projects, such as:Managing form inputs with state.Fetching and displaying data from APIs.Persisting references across renders.Creating and consuming a context for global state management.By the end of the course, you'll not only understand these hooks conceptually but also feel confident using them to solve real-world challenges in your React applications.Who Is This Course For?This course is ideal for beginners who:Have a basic understanding of React.Want to learn how to work with hooks in functional components.Prefer practical, example-driven learning.Whether you're looking to solidify your React knowledge or prepare for more advanced topics, "Master React Hooks by Example" will equip you with the skills to build powerful, modern React applications.Enroll now and start mastering React 17, 18 and 19 hooks today!
