TypeScript 4 Design Patterns and Best Practices

By: Theofanis Despoudis

Overview of this book

Design patterns are critical armor for every developer to build maintainable apps. TypeScript 4 Design Patterns and Best Practices is a one-stop guide to help you learn design patterns and practices to develop scalable TypeScript applications. It will also serve as handy documentation for future maintainers. This book takes a hands-on approach to help you get up and running with the implementation of TypeScript design patterns and associated methodologies for writing testable code. You'll start by exploring the practical aspects of TypeScript 4 and its new features. The book will then take you through the traditional gang of four (GOF) design patterns in their classic and alternative form and show you how to use them in real-world development projects. Once you've got to grips with traditional design patterns, you'll advance to learning about their functional programming and reactive programming counterparts and how to couple them to deliver better and more idiomatic TypeScript code. By the end of this TypeScript book, you'll be able to efficiently recognize when and how to use the right design patterns in any practical use case and gain the confidence to work on scalable and maintainable TypeScript projects of any size.

Summary

The advanced language primitives discussed throughout this chapter are really helpful language features when it comes to defining the exact types in our abstractions.

If you work with TypeScript and adhere to OOP principles, you will find that some abstractions lead to low-coupled code, while others such as inheritance achieve the opposite as they can increase code coupling if modeled incorrectly.

TypeScript is a truly multi-paradigm language that can be used equally successfully in the browser and the server environment. However, it's significant to understand that each environment presents different challenges, so they call for alternative approaches.

By learning about design patterns, you can understand how those proven and reliable concepts designed by software experts can help manage complexity at scale whether we use OOP or any other programming style.

In the next chapter, you will gain a more in-depth understanding of design patterns as you start learning...
