"AngularJS: Up and Running 是一本2014年的技术指南,由曾在Google参与AngularJS开发的Shyam Seshadri和Brad Green撰写,旨在帮助初学者和有经验的开发者逐步掌握AngularJS框架,从基础到高级概念进行深入学习。这本书将教会读者如何使用AngularJS构建大型、可维护且高性能的数据驱动应用,同时采用声明式编程和模型-视图-控制器(MVC)模式。此外,书中还涵盖了单元测试的实施方法,以确保应用的每个部分都能得到充分验证。" AngularJS是Google开发的一个JavaScript框架,它提供了一种结构化的Web应用程序开发方式,显著提高了开发效率。本书首先介绍了AngularJS的基本原理,解释了为何选择这个框架,然后逐步引导读者通过实践学习其核心概念。作者的背景为读者提供了权威和深入的见解。 书中的关键知识点包括: 1. **AngularJS基础**:了解AngularJS的核心概念,如依赖注入、指令、服务、过滤器等,这些是构建动态Web应用的基础。 2. **声明式编程**:AngularJS的一大特点就是使用声明式的方式来描述UI与数据之间的关系,使得代码更简洁易懂,减少了手动操作DOM的复杂性。 3. **模型-视图-控制器(MVC)模式**:AngularJS实现了MVC架构,使得代码组织更加清晰,模型负责数据管理,视图负责展示,控制器则作为两者之间的桥梁。 4. **双向数据绑定**:AngularJS的双向数据绑定是其标志性特性,允许模型和视图之间的即时同步,简化了数据处理。 5. **模块化**:通过模块(ngModule)来组织应用,方便代码重用和管理,有助于构建大型应用。 6. **路由**:学习如何使用AngularJS的路由系统实现页面间的导航,创建单页应用(SPA)。 7. **指令系统**:自定义指令是AngularJS强大的扩展机制,用于封装HTML行为,创建可复用的UI组件。 8. **服务**:学习如何使用服务(Service)来封装业务逻辑,提供跨组件通信的途径。 9. **测试**:单元测试是保证代码质量的重要环节,书中会介绍如何对AngularJS应用的各个部分进行单元测试,如测试控制器、服务、指令等。 10. **最佳实践**:作者分享了在Google工作中积累的最佳实践,帮助读者避免常见陷阱,提升应用性能和可维护性。 通过阅读这本书,无论是前端开发者还是希望拓宽技能树的程序员,都可以系统地学习并掌握AngularJS框架,从而有效地构建和维护现代Web应用程序。同时,配套的代码仓库提供了实际操作的示例,进一步加深理解。

Chapter 1, Introducing Angular, is an introduction to Angular as well as the concepts behind it. It also covers what it takes to start writing an Angular application. Chapter 2, Hello Angular, walks through creating a very simple Angular application, and diving into how the pieces work together. It also introduces the Angular CLI. Chapter 3, Useful Built-In Angular Directives, digs into the basic built-in Angular directives (including ngFor, ngIf, etc.) and when and how to use them. Chapter 4, Understanding and Using Angular Components, covers Angular components in more detail, as well as the various options available when creating them. It also covers the basic lifecycle hooks available with components. Chapter 5, Testing Angular Components, introduces how to unit test angular components using Karma and Jasmine, along with the Angular testing framework. Chapter 6, Working with Template-Driven Forms, covers creating and working with forms in Angular, specifically template-driven forms. Chapter 7, Working with Reactive Forms, covers the other way of defining and working with forms, which is how to create and develop reactive forms. Chapter 8, Angular Services, covers Angular services, which includes how to use built-in Angular services, as well as how and when to define our own Angular services. Chapter 9, Making HTTP Calls in Angular, moves into the server communication aspect of Angular, and delves into making HTTP calls, as well as some advanced topics like interceptors and the like. Chapter 10, Unit Testing Services, takes a step back and covers unit testing again, but this time with a focus on unit testing services. This includes testing simple services and slightly harder cases like asynchronous flows as well as services and components that make HTTP calls. Chapter 11, Routing in Angular, goes in depth into how we can accomplish routing in an Angular application and covers the Angular routing module in detail as well as a majority of its features. Chapter 12, P
