In this talk, I will share my experience and best practices for building reusable and customizable React components using TypeScript and Tailwind CSS. We will explore how TypeScript interfaces can be used to create polymorphic components, and how Tailwind CSS can be used to style them consistently. We'll also cover using Vite and Storybook for easier development and better documentation. Attendees will learn how to create a scalable and maintainable component library with these tools and techniques.
