Overview of this book

Angular 2 introduces an entirely new way to build applications. It wholly embraces all the newest concepts that are built into the next generation of browsers, and it cuts away all the fat and bloat from Angular 1. This book plunges directly into the heart of all the most important Angular 2 concepts for you to conquer. In addition to covering all the Angular 2 fundamentals, such as components, forms, and services, it demonstrates how the framework embraces a range of new web technologies such as ES6 and TypeScript syntax, Promises, Observables, and Web Workers, among many others. This book covers all the most complicated Angular concepts and at the same time introduces the best practices with which to wield these powerful tools. It also covers in detail all the concepts you'll need to get you building applications faster. Oft-neglected topics such as testing and performance optimization are widely covered as well. A developer that reads through all the content in this book will have a broad and deep understanding of all the major topics in the Angular 2 universe.

Configuring ViewEncapsulation for maximum efficiency


Although it may sound clichéd, Angular 2 was built for the browsers of tomorrow. You can point to why this is the case in a large number of ways, but there is one way where this is extremely true: component encapsulation.

The ideal component model for Angular 2 is the one in which components are entirely sandboxed, save for the few pieces that are externally visible and modifiable. In this respect, it does a bang-up job, but even the most modern browsers limit its ability to strive for such efficacy. This is especially true in the realm of CSS styling.

Several features of Angular's component styling are especially important:

  • You are able to write styles that are guaranteed to be only applicable to a component

  • You can explicitly specify styles that should be inherited downward through the component tree

  • You can specify an encapsulation strategy on a piecewise basis

There are a number of interesting ways to accomplish an efficient component styling...
