Overview of this book

TypeScript is both a language and a set of tools to generate JavaScript. It was designed by Anders Hejlsberg at Microsoft to help developers write enterprise-scale JavaScript. Starting with an introduction to the TypeScript language, before moving on to basic concepts, each section builds on previous knowledge in an incremental and easy-to-understand way. Advanced and powerful language features are all covered, including asynchronous programming techniques, decorators, and generics. This book explores many modern JavaScript and TypeScript frameworks side by side in order for the reader to learn their respective strengths and weaknesses. It will also thoroughly explore unit and integration testing for each framework. Best-of-breed applications utilize well-known design patterns in order to be scalable, maintainable, and testable. This book explores some of these object-oriented techniques and patterns, and shows real-world implementations. By the end of the book, you will have built a comprehensive, end-to-end web application to show how TypeScript language features, design patterns, and industry best practices can be brought together in a real-world scenario.

In this chapter, we took an in-depth look at building an Angular application from the ground up. We experimented with a left-to-right page transition design and learned how to manipulate CSS styles and CSS transitions to create a visually appealing application. Unfortunately, our initial attempts in creating this application ended up with a lot of confusing and hard-to-fix local variables, as we attempted to keep all of the page elements under control.

We then took a step back, and discussed how the State and Mediator design patterns could help us to manage page transitions. We then re-built our application into meaningful components, and took a detailed look into how to apply the State and Mediator patterns to manage our application state, and complex page transitions.

In the next chapter, we will take a look at the concept of dependency injection, and how we can use...
