Apply time-tested design patterns and techniques to build robust and maintainable applications using modern practices Key Features: - Identify and avoid common gotchas and anti-patterns in TypeScript app development - Leverage functional and reactive paradigms for effective TypeScript development - Discover how to improve your application's code reusability and testability - Purchase of the print or Kindle book includes a free PDF eBook Book Description: Design patterns are the backbone of many world-renowned software applications, both commercial and open source. Written by a well-known author and accomplished software developer, this in-depth guide will empower you to build robust and scalable TypeScript apps with design patterns in TypeScript 5, making it your go-to resource for mastering TypeScript and leveraging design patterns effectively. This second edition has been updated with TypeScript 5 features, such as improved type inference, union enums, and decorators to write clean and maintainable code that can adapt to future changes. The chapters teach you the classic Gang of Four design patterns, providing traditional and modern real-world implementations. You'll also get a clear understanding of the power of functional and reactive programming patterns that have been specifically designed for idiomatic TypeScript development. By the end of this book, you'll be a design pattern pro, capable of confidently identifying and applying the right pattern for any scenario, as well as crafting well-structured, maintainable, and testable TypeScript code. What You Will Learn: - Comprehend the principles of design patterns and their role in TypeScript development - Explore essential design patterns, including creational, structural, and behavioral patterns with TypeScript - Differentiate between design patterns and design concepts and apply them effectively - Develop practical expertise in implementing design patterns in TypeScript projects through in-depth insights - Explore advanced patterns from functional and reactive programming paradigms - Architect scalable and robust TypeScript apps using design patterns and best practices Who this book is for: If you're a TypeScript developer looking to learn how to apply established design patterns to solve common programming problems instead of reinventing solutions, you'll find this book useful. Prior knowledge of design patterns is not necessary-all you need is basic TypeScript knowledge to get started with this boo
