ABOUT THIS COURSE
TypeScript has become the de facto way to build modern web applications. With the rise of design systems and reusable components, building strongly typed polymorphic components is a desirable skill for the modern web engineer.
This course provides a bottom-up approach to building strongly typed polymorphic components. You will start with a naive implementation of a polymorphic component and explore its drawbacks. You will then use TypeScript to provide a production-ready component interface. Finally, you’ll support advanced use cases with component refs and build a reusable utility you can use on multiple components.
By the end of the course, you’ll be ready to build components fit for a design system and go beyond basic reusable needs.
