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.

User interface design

As an example of the use of the SOLID design principles, let's build an application that uses a complex UI design, and see how these principles can help us break up our code into smaller, manageable modules, separated by interfaces.

In this section, we will build an Angular application that will provide a left-to-right panel style page layout. We will use Bootstrap to provide a little styling, and some CSS-based transitions to slide panels in from the left or right. This will provide the user with a slightly different browsing experience to the common up-down scrolling design that most websites utilize.

Conceptual design

Let's take a look at what this left-to-right design will look like conceptually...
