Design Patterns in TypeScript


Write cleaner code and enhance your development skills with TypeScript design patterns

What you’ll learn

  • Identify and avoid violations of the SOLID Principles
  • Create single instances of classes throughout your apps with the Singleton pattern
  • Use factories to get instances and object pools
  • Understand Dependency Injection and work with its benefits
  • Use InversifyJS and learn about dependency scope
  • Extend objects with the Decorator pattern


  • No prior knowledge of design patterns is required for this course.


In programming, there are several problems that occur frequently. To solve these problems, there are various repeatable solutions; these are known as design patterns. Design patterns are a great way to improve the efficiency of your programs and improve your productivity; you’ll learn them all in this course. This course is a collection of the most important patterns you need to improve application performance and productivity.

This course starts by exploring SOLID principles to write clean code. Then you will create new objects and instance of classes with creational design Patterns. Next, you will utilize dependency injection with InversifyJS to create testable, maintainable, and extensible code.

Moving on, you will explore structural design patterns to better express the relationships between different application entities. Lastly, you will investigate behavioral patterns to add flow to your applications and add levels of communication between your entities.
