Chapter 2. Understanding Class Decorator | Typescript Masterclass | Code With Soumyajeet

Welcome to the TypeScript Masterclass! In this video, we're diving deep into one of the most powerful features of TypeScript—**class decorators**. A class decorator is a special kind of decorator that can be applied to a class to modify or enhance its behavior without altering the class itself. It's a design pattern that allows you to apply reusable logic, such as logging, validation, or dependency injection, in a clean and structured way. In this video, we will: - Explain what class decorators are and how they work. - Show you practical, real-world examples of class decorators in action. - Walk through several use cases to help you understand how to leverage class decorators in your own TypeScript projects. By the end of this video, you'll have a solid grasp of how to use class decorators to write cleaner, more maintainable code. So, if you're ready to master class decorators and explore how to use them effectively, hit play and let's get started! **Source Code:** Base Setup: https://github.com/SoumyajeetNayak/typescript-masterclass/tree/basesetup Completed Code: https://github.com/SoumyajeetNayak/typescript-masterclass/tree/decorators **Video Timestamps** 00:00 Coming Up... 00:44 Topic Introduction 02:17 Project Setup 03:10 Introduction to Class Decorator 03:38 Understanding Decorator Function Syntax and Writing our First Decorator 24:00 Second Decorator Example 29:36 Decorator Factory Function 32:40 Practice Question for you to Solve on your Own 34:12 Conclusion and Outro My Blog Page: https://jeetsoftwares.com/ Subscribe to my newsletter: https://jeetsoftwares.com/newsletter/ Linked In: https://www.linkedin.com/in/soumyajeet-nayak-82593a79/ Instagram: https://www.instagram.com/code_with_soumyajeet/ Subscribe to YouTube Channel : https://www.youtube.com/channel/UCkoVDxXrQVuRjMIM3SnqXEQ Please like the video and Subscribe to my Channel
