"本书《使用Redux、RxJS和NgRx构建Angular应用》旨在教你如何用Angular 6构建高性能的Redux风格应用,作者是Christoffer Noring。" 在Angular框架中,Redux、RxJS和NgRx是构建复杂状态管理应用的关键技术。Redux是一个流行的状态管理模式,它适用于构建可预测、可测试且易于理解的应用状态。Angular 6是Google维护的前端开发框架,用于构建大型企业级单页应用。 1. **Redux**:Redux的核心理念是单一数据源和纯函数。它将应用的所有状态集中在一个store中,通过actions和reducers来改变状态。Redux强调状态不可变性,使得应用状态的变更可跟踪,有利于调试和测试。在Angular中,开发者可以使用NgRx库,它是Angular对Redux模式的实现。 2. **RxJS**:RxJS(Reactive Extensions for JavaScript)是处理异步数据流的库,它使用 Observables 来处理事件、数据流和其他异步操作。RxJS与Redux结合使用,可以在状态变化时触发副作用,如API调用或UI更新。它提供了一套强大的操作符,使得数据流的组合、过滤和转换变得简单。 3. **NgRx**:NgRx是Angular生态中的状态管理工具集,它结合了Redux的设计理念和RxJS的功能。NgRx包括Store(状态存储)、Effects(副作用处理)、Actions(状态变更触发器)和Selectors(选择器,用于获取store中的部分状态)。通过NgRx,开发者可以创建可测试、模块化的状态管理解决方案,这在大型Angular应用中尤为重要。 在本书中,读者将学习如何设计和实现: - 如何设置NgRx Store,定义Actions和Reducers,以及如何在Angular组件中使用它们来读取和修改应用状态。 - 使用NgRx Effects来处理副作用,如HTTP请求,确保这些操作不会阻塞应用的主流程。 - 如何编写Selectors以高效地获取和订阅store中的特定状态部分。 - 整合RxJS和NgRx,利用Observables进行复杂的逻辑和数据流处理。 - 如何测试和调试Redux风格的Angular应用,确保其正确性和性能。 通过深入学习这些概念和技术,开发者能够构建出更稳定、可维护且高性能的Angular应用。书中的实践示例和指导将帮助读者将理论知识转化为实际开发技能。

A hands-on guide with a minimalist and flexible approach that enables quick learning and rapid delivery of cloud-ready enterprise applications with Angular 6 Key Features Explore tools and techniques to push your web app to the next level Master Angular app design and architectural considerations Learn continuous integration and deploy your app on a highly available cloud infrastructure in AWS Book Description Angular 6 for Enterprise-Ready Web Applications follows a hands-on and minimalist approach demonstrating how to design and architect high quality apps. The first part of the book is about mastering the Angular platform using foundational technologies. You will use the Kanban method to focus on value delivery, communicate design ideas with mock-up tools and build great looking apps with Angular Material. You will become comfortable using CLI tools, understand reactive programming with RxJS, and deploy to the cloud using Docker. The second part of the book will introduce you to the router-first architecture, a seven-step approach to designing and developing mid-to-large line-of-business applications, along with popular recipes. You will learn how to design a solid authentication and authorization experience; explore unit testing, early integration with backend APIs using Swagger and continuous integration using CircleCI. In the concluding chapters, you will provision a highly available cloud infrastructure on AWS and then use Google Analytics to capture user behavior. By the end of this book, you will be familiar with the scope of web development using Angular, Swagger, and Docker, learning patterns and practices to be successful as an individual developer on the web or as a team in the Enterprise. What you will learn Create full-stack web applications using Angular and RESTful APIs Master Angular fundamentals, RxJS, CLI tools, unit testing, GitHub, and Docker Design and architect responsive, secure and scalable apps to deploy on AWS Adopt a minimalist,
