This book is your detailed map of every feature and its use cases. The author has done all the hard work of fitting everything Angular 2 means for developers together for you, making this book the quickest way to learn Angular 2 from scratch. Who This Book Is For This book is targeted at web developers who want to build the next generation of state-of-the-art mobile and desktop web applications with Angular 2. This book does not require you to have prior exposure to either Angular 1.x or 2, although comprehensive knowledge of JavaScript is assumed. It's great for newcomers to Angular who learn best through clear explanations and definitions of concepts. What You Will Learn Set up your working environment in order to have all the tools you need to start building Angular 2 components with minimum effort Get up to speed with TypeScript, a powerful typed superset of JavaScript that compiles to plain JavaScript Take full control of how your data is rendered and updated upon data changes Build powerful web applications based on structured component hierarchies that emit and listen to events and data changes throughout the elements tree Explore how to consume external APIs and data services and allow data editing by harnessing the power of web forms made with Angular 2 Deliver seamless web navigation experiences with application routing and state handling common features with ease Discover how to bulletproof your applications by introducing smart unit testing techniques and debugging tools In Detail Angular 2 was conceived as a complete rewrite in order to fulfill the expectations of modern developers who demand blazing fast performance and responsiveness from their web applications. This book will help you learn the basics of how to design and build Angular 2 components right from the beginning, providing full coverage of the TypeScript syntax required to follow the examples included. From that point on, we will build upon our first components, interconnect them, and give shape to larger web applications. We will then move to implementing routing in Angular 2, analyzing how to handle application states, and navigating from one component to another in depth. After this, the book features full coverage of web forms and user input validation, later leveraging all of this information to go through the basics of implementing user authentication in Angular 2 and providing a bird's eye view of the different strategies at hand to secure pages and areas of your website. Animating components and DOM elements with Angular 2 is also covered in this book. The final part of this book provides broad insights into how to unit test components and other modules such as services, directives, routes or pipes. Style and approach This book covers everything there is to know about getting well-acquainted with Angular without bogging you down. Everything is neatly laid out under clear headings for quick consultation, offering you the information required to understand a concept immediately, with short relevant examples of each feature.

Over the past years, Angular 1.x has became one of the most ubiquitous JavaScript frameworks for building cutting edge web applications, either big or small. At some point, its shortcomings with regard to performance and scalability became too prominent as soon as applications grew in size and complexity. Angular 2 was then conceived as a full rewrite from scratch to fulfill the expectations of modern developers, who demand blazing fast performance and responsiveness in their web applications. Angular 2 has been designed with modern web standards in mind and allows full flexibility when picking up your language of choice, providing full support for ES6 and TypeScript, but working equally well with today's ES5, Dart, or CoffeeScript. Its built-in dependency injection functionalities let the user build highly scalable and modular applications with an expressive and self-explanatory code, turning maintainability tasks into a breeze, while simplifying test- driven development to the max. However, where Angular 2 stands out is when it shows off its unparalleled level of speed and performance, thanks to its new change detection system that is up to five times faster than its previous incarnation. Cleaner views and an unsurpassed standards-compliant templating syntax compound an endless list of powerful features for building the next generation of web mobile and desktop apps. Angular 2 is here to stay and will become a game changer in the way modern web applications are envisioned and developed in the years to come. However, and due to its disruptive design and architecture, learning Angular 2 might seem a daunting effort to newcomers. This is where this book comes in—its goal is to avoid bloating the reader with API references and framework descriptions, but to embrace a hands-on approach, helping the reader learn how to leverage the framework to build stuff that matters right from day one. This is learning by doing right from the start. This book aims to give developers a complete walkthrough of this new platform and its TypeScript-flavored syntax by building a web project from back to forth, starting from the basic concepts and sample components and iterating on them to build up more complex functionalities in every chapter until we launch a complete, tested, production-ready sample web application by the end of the book.

Chapter 1, Creating our First Component in Angular, covers Semantic versioning. This is an important concept to grasp, so you know whether to adopt new releases based on your needs. This chapter also introduces the reader to the Angular CLI and the reader will be taking their first steps into writing an Angular application. Chapter 2, IDEs and Plugins, introduces you to the most popular IDEs. The most common Angular plugins and snippets are also described to further boost developer productivity. Chapter 3, Introducing TypeScript, introduces TypeScript, which is the chosen language for coding Angular apps. There is more to TypeScript than just adding types. Your code can be made elegant and more secure, and using the right features will save you from typing quite a lot. Chapter 4, Implementing Properties and Events in our Components, covers how to send data to components and how to bind methods to them so that the components have the ability to communicate upstream. Chapter 5, Enhancing our Component with Pipes and Directives, shows how you can make your component more consistent and reusable with the help of pipes and directives. Chapter 6, Building an Application with Angular Components, dives right into our goal of building a real application. We address how to think and how to use the most common structural directives in order to control how the data should be displayed and act when being manipulated by UI elements. Chapter 7, Asynchronous Data Services with Angular, introduces the RxJS library, which not only helps us with AJAX but also facilitates reactive application patterns. All things async become one concept under RxJS, the possibilities that this introduces are endless. Chapter 8, Firebase, explains Firebase, which is a product by Google that allows you to have backend as a service. Firebase lets you focus on building Angular apps while it takes care of almost everything else. The best part is Firebase's reactive nature, which makes chat-like applications as well as collaboration apps a breeze to create. Chapter 9, Routing, explains the concept of routing, so you can scale your application seamlessly. Chapter 10, Forms in Angular, covers the two main ways of dealing with forms and user input: template-driven and the reactive approach. Chapter 11, Angular Material, takes you through Angular Material, which not only offers a beautiful interface but also comes with a bunch of components that will make it a piece of cake to quickly assemble an impressive application. Chapter 12, Animating Components with Angular, covers how well Angular supports the developer in leveraging and controlling quite advanced animations. Chapter 13, Unit Testing in Angular, explains unit testing in Angular. The Angular team has really added first-class support for testing, so you, with a very few lines of code, are able to test all the possible constructs your mind can dream up. Everything from component, service, and directives to E2E testing. Appendix A, SystemJS, covers SystemJS, which is a module loader and used to be the only way to set up an Angular application. It's still a valid way to set up your project. This Appendix will cover the core parts of SystemJS and zoom in on the Angular set up bit in particular. Appendix B, Webpack with Angular, aims at showing the developer how to set up your Angular project with Webpack. There definitely exists a user base that wants complete control of every aspect of a web project. If that is you, then this appendix is for you.
