React Cookbook: Recipes for Mastering the React Framework

React helps you create and work on an app in just a few minutes. But learning how to put all the pieces together is hard. How do you validate a form? Or implement a complex multistep user action without writing messy code? How do you test your code? Make it reusable? Wire it to a backend? Keep it easy to understand? The React Cookbook delivers answers fast.

Many books teach you how to get started, understand the framework, or use a component library with React, but very few provide examples to help you solve particular problems. This easy-to-use cookbook includes the example code developers need to unravel the most common problems when using React, categorized by topic area and problem.

You'll learn how to:

• Build a single-page application in React using a rich UI
• Create progressive web applications that users can install and work with offline
• Integrate with backend services such as REST and GraphQL
• Automatically test for accessibility problems in your application
• Secure applications with fingerprints and security tokens using WebAuthn
• Deal with bugs and avoid common functional and performance problems

React能夠幫助你在短短幾分鐘內創建和開發應用程式。但是，學習如何將所有組件組合在一起是困難的。如何驗證表單？或者在不寫亂七八糟的代碼的情況下實現複雜的多步驟用戶操作？如何測試代碼？使其可重用？如何將其與後端連接？如何保持易於理解？《React Cookbook》能夠快速提供答案。

許多書籍教你如何入門，理解框架，或者使用React的組件庫，但很少有提供示例來幫助你解決特定問題。這本易於使用的食譜書包含開發人員需要解決React時最常見問題的示例代碼，按主題和問題進行分類。

你將學習如何：
- 使用豐富的用戶界面在React中構建單頁應用程式
- 創建用戶可以離線安裝和使用的漸進式Web應用程式
- 與REST和GraphQL等後端服務集成
- 自動測試應用程式中的可訪問性問題
- 使用WebAuthn的指紋和安全令牌保護應用程式
- 處理錯誤並避免常見的功能和性能問題
