"O'Reilly Learning React 2nd Edition 2020.6" 本书《Learning React》第二版由Alex Banks和Eve Porcello撰写,主要探讨了开发React应用的现代模式。React是Facebook推出的一个用于构建用户界面的JavaScript库,尤其在构建单页应用程序(SPA)方面表现突出。随着TypeScript的日益普及,这本书也涉及了使用TypeScript与React结合的实践,提供了一种更强大、类型安全的方式来开发React应用。 在React的世界里,开发者可以通过组件化的方式构建可复用的UI代码,从而提高开发效率和代码质量。本书详细介绍了React的基础概念,包括JSX语法、组件生命周期、状态管理、事件处理、以及如何利用React Hooks进行无状态组件和状态管理。React Hooks是React 16.8引入的新特性,它允许在不编写类组件的情况下使用状态和其他React功能。 此外,书中还涵盖了React Router,这是React社区广泛使用的路由解决方案,它帮助开发者在单页应用中实现页面间的导航和状态管理。React Native,一个可以让开发者使用React来构建原生移动应用的框架,也在书中有所提及,展示了React技术栈的跨平台能力。 在实际项目中,性能优化是必不可少的一环。本书会讲解如何使用React的PureComponent、shouldComponentUpdate和React.memo等工具来减少不必要的渲染,以及如何使用Profiler工具来分析和优化应用性能。此外,还会介绍如何通过代码分割和懒加载来提升应用的加载速度。 测试和调试是软件开发过程中的关键部分。《Learning React》第二版将介绍Jest和Enzyme等工具,它们是React生态系统中常用的测试框架,用于编写单元测试和集成测试。同时,书中还会讲解如何使用Chrome开发者工具来调试React应用,找出并修复问题。 最后,作者可能会讨论React生态中的其他重要库和工具,如Redux(用于全局状态管理)、Apollo GraphQL(用于GraphQL API的客户端)以及 styled-components(一种CSS-in-JS解决方案),这些工具可以帮助开发者构建更复杂、更健壮的应用。 《Learning React》第二版是一本全面而深入的React指南,适合React初学者和有经验的开发者阅读,无论你是想学习React的基本原理还是寻求更高级的开发技巧,都能在本书中找到答案。通过学习,读者将能够掌握React的核心概念,并利用TypeScript的强类型特性,提升React应用的质量和可维护性。

Learning React A hands-on guide to building web applications using React and Redux As far as new web frameworks and libraries go, React is quite the runaway success. It not only deals with the most common problems developers face when building complex apps, it throws in a few additional tricks that make building the visuals for such apps much, much easier. What React isn’t, though, is beginner-friendly and approachable. Until now. In Learning React , author Kirupa Chinnathambi brings his fresh, clear, and very personable writing style to help web developers new to React understand its fundamentals and how to use it to build really performant (and awesome) apps. The only book on the market that helps you get your first React app up and running in just minutes, Learning React is chock-full of colorful illustrations to help you visualize difficult concepts and practical step-by-step examples to show you how to apply what you learn. Build your first React app Create components to define parts of your UI Combine components into other components to build more complex UIs Use JSX to specify visuals without writing full-fledged JavaScript Deal with maintaining state Work with React’s way of styling content Make sense of the mysterious component lifecycle Build multi-page apps using routing and views Optimize your React workflow using tools such as Node, Babel, webpack, and others Use Redux to make managing your app data and state easy Contents at a Glance 1 Introducing React 2 Building Your First React App 3 Components in React 4 Styling in React 5 Creating Complex Components 6 Transferring Properties 7 Meet JSX...
