Let me start by saying: I love Tailwind. Tailwind CSS empowers frontend developers, like me, to quickly turn design concepts into functional designs. It shines in component-based frameworks like React, allowing developers to style interfaces directly within their markup, eliminating the need for traditional CSS or CSS-in-JS. This focus enhances both the functionality and reliability of applications. This article outlines some key strategies that I use for building reusable React components with Tailwind CSS, adhering to component design best practices.

What is Tailwind CSS and Why Use It?

Tailwind CSS is a utility-first framework that lets you apply CSS properties directly to your HTML, enabling a highly customizable style approach by combining utility classes.

Unlike UI-first frameworks that offer pre-designed components, Tailwind CSS provides more flexibility, allowing developers to tailor components to project-specific requirements.

Here’s an example of a CTA link button using Tailwind CSS in HTML:

1<a href="#" class="text-white bg-sky-500 border-0 py-3 px-8 focus:outline-none hover:bg-sky-600 rounded-full text-lg mt-10 sm:mt-0">

Writing Better React Components

The best practice is to avoid premature abstraction; start with simple markup and refine into components as your application's structure becomes clearer. Tailwind CSS supports this iterative approach by allowing rapid styling changes within a single file.

Choosing the Right Component API

A well-designed component API enhances code quality and maintainability. Here are some guidelines:

  • Explicit UI States: Define UI states clearly to avoid invalid state combinations.
  • Avoid CSS Classes as Props: This can obscure the component's state and lead to bugs.
  • Local vs. Global State: Manage state locally unless synchronization across components is needed.
  • Prefer Props Over State: Use props to increase component flexibility and reusability.
  • Simplify Component APIs: Use distinct components for different variations rather than overloading a single component with multiple responsibilities.
  • Functional vs. Class Components in React
  • Functional components are generally preferred for their simplicity and compatibility with React Hooks, though class components may be necessary for complex state management or lifecycle control.
  • Testing with a Badge Component

Here’s how you can create a Button component in React and Tailwind CSS, demonstrating the use of TypeScript for type safety:

1enum ButtonVariant {
5enum ButtonSize {
9const SIZE_MAPS: Record<ButtonSize, string> = {
10  [ButtonSize.SMALL]: 'px-4 py-2 text-sm',
11  [ButtonSize.MEDIUM]: 'px-6 py-3 text-base',
12  [ButtonSize.LARGE]: 'px-8 py-4 text-lg',
15const VARIANT_MAPS: Record<ButtonVariant, string> = {
16  [ButtonVariant.PRIMARY]: 'bg-blue-500 text-white hover:bg-blue-600',
17  [ButtonVariant.SECONDARY]: 'bg-gray-500 text-white hover:bg-gray-600',
18  [ButtonVariant.SUCCESS]: 'bg-green-500 text-white hover:bg-green-600',
19  [ButtonVariant.DANGER]: 'bg-red-500 text-white hover:bg-red-600',
22type ButtonProps = {
23  variant: ButtonVariant;
24  children?: React.ReactNode;
25  size: ButtonSize;
28export default function Button({ children, variant, size }: ButtonProps) {
29  const buttonClasses = `inline-flex items-center justify-center font-medium leading-none rounded-md focus:outline-none focus:ring-2 focus:ring-offset-2 ${VARIANT_MAPS[variant]} ${SIZE_MAPS[size]}`;
30  return <button className={buttonClasses}>{children}</button>;
33Button.defaultProps = {
34  variant: ButtonVariant.PRIMARY,
35  size: ButtonSize.MEDIUM,


For me, the combination of React and Tailwind CSS provide a powerful combination for building modern, component-based web applications with streamlined styling capabilities. This allows developers to create highly reusable components that integrate seamlessly into any project.
