Tailwind CSS Best Practices for Production
Tailwind CSS has become the go-to CSS framework for modern web development. Here's how to use it effectively in production applications.
Configuration
Custom Design Tokens
Extend the default theme with your brand:
// tailwind.config.js
module.exports = {
theme: {
extend: {
colors: {
brand: {
50: '#eff6ff',
500: '#3b82f6',
900: '#1e3a8a',
},
},
fontFamily: {
sans: ['Inter', 'system-ui', 'sans-serif'],
},
},
},
};Component Patterns
Using clsx/className Merging
import { clsx } from 'clsx';
function Button({ variant, className, children }: ButtonProps) { return ( <button className={clsx( 'px-4 py-2 rounded-lg font-medium transition-colors', variant === 'primary' && 'bg-brand-500 text-white hover:bg-brand-600', variant === 'secondary' && 'bg-gray-100 text-gray-900 hover:bg-gray-200', className )} > {children} </button> ); }
Extracting Components
Don't repeat yourself—create reusable components for common patterns.
Performance
Production Build
Tailwind automatically purges unused styles in production:
// Ensure content paths are correct
module.exports = {
content: [
'./src/*/.{js,ts,jsx,tsx,mdx}',
],
};Critical CSS
Consider extracting critical CSS for above-the-fold content.
Organization
Group Related Classes
Keep your class strings organized:
<div
className={clsx(
// Layout
'flex flex-col md:flex-row gap-4',
// Sizing
'w-full max-w-4xl',
// Spacing
'p-6 md:p-8',
// Visual
'bg-white rounded-xl shadow-lg',
)}
/>Dark Mode
Implement dark mode with the class strategy:
<html className="dark">
<body className="bg-white dark:bg-gray-900 text-gray-900 dark:text-white">
{/ Content /}
</body>
</html>Conclusion
Tailwind CSS scales beautifully when you follow these patterns. Focus on component extraction, proper configuration, and consistent organization.
