Overview of this book

Writing clean, object-oriented code in JavaScript gets trickier and complex as the size of the project grows. This is where Typescript comes into the picture; it lets you write pure object-oriented code with ease, giving it the upper hand over JavaScript. This book introduces you to basic TypeScript concepts by gradually modifying standard JavaScript code, which makes learning TypeScript easy for C# ASP.NET developers. As you progress through the chapters, you'll cover object programming concepts, such as classes, interfaces, and generics, and understand how they are related to, and similar in, both ES6 and C#. You will also learn how to use bundlers like WebPack to package your code and other resources. The book explains all concepts using practical examples of ASP.NET Core projects, and reusable TypeScript libraries. Finally, you'll explore the features that TypeScript inherits from either ES6 or C#, or both of them, such as Symbols, Iterables, Promises, and Decorators. By the end of the book, you'll be able to apply all TypeScript concepts to understand the Angular framework better, and you'll have become comfortable with the way in which modules, components, and services are defined and used in Angular. You'll also have gained a good understanding of all the features included in the Angular/ASP.NET Core Visual Studio project template.

Chapter 13

  1. Two hierarchies: the hierarchy of component instances and the hierarchy of lazy-loaded components.
  2. Angular bundler is able to perform better optimization, adding services only to the bundles where they are needed.
  3. Three ways: direct creation, direct specification of an instance, and a farm function. Normally, a token can be associated to just one service in a container, but if the provider multi property is set to true, several services can be added to the same token.
  4. get, head, post, put, delete, and patch.
  5. See the Communication progress events subsection.
  6. In an XSRF attack, a hacker forces the user to submit a request to a website where they are already authenticated with an authentication cookie. The safest way to handle authentication in SPAs is with authentication tokens placed in each request header.
  7. Yes, with the help of interceptors.
  8. loadChildren.
  9. preloadingStrategy...
