Core Library Patterns
Lucide React - General Purpose (1000+ icons)
import { Heart, Search, Settings, ChevronRight } from 'lucide-react'
export function LucideExample() {
return (
<div className="space-y-4">
{/* Basic usage (24px default) */}
<div className="flex items-center gap-2">
<Search />
<span>Search</span>
</div>
{/* Custom styling */}
<Heart size={32} color="#ff0000" fill="#ff0000" />
{/* Tailwind integration */}
<Settings className="w-6 h-6 text-gray-500 hover:text-gray-900" />
{/* Icon button */}
<button className="p-2 rounded-lg hover:bg-gray-100">
<ChevronRight size={20} />
</button>
</div>
)
}
React Icons - Multi-Library (35K+ icons)
import { FaHome } from "react-icons/fa"
import { MdHome } from "react-icons/md"
import { BsHouse } from "react-icons/bs"
import { FiHome } from "react-icons/fi"
import { SiReact } from "react-icons/si"
export function MultiLibraryExample() {
return (

import { Heart, Star } from "@phosphor-icons/react"
export function PhosphorExample() {
const [rating, setRating] = React.useState(3)
return (
<div className="space-y-4">
{/* Weight variations */}
<div className="flex gap-2">
<Heart weight="thin" />
<Heart weight="light" />
<Heart weight="regular" />
<Heart weight="bold" />
<Heart weight="fill" />
</div>
{/* Interactive rating */}
<div className="flex gap-1">
{[1, 2, 3, 4, 5].map((star) => (
<button key={star}>
<Star
weight={star <= rating ? "fill" : "regular"}
size={24}
color={star <= rating ? "#fbbf24" : "#d1d5db"}
/>
</button>
))}
</div>
</div>
)
}
Iconify - Universal Framework (200K+ icons)
import { Icon } from "@iconify/react"
export function IconifyExample() {
return (
<div className="space-y-4">
{/* String-based (CDN loaded) */}
<Icon icon="fa:home" width="32" height="32" />
<Icon icon="mdi:account" width="32" height="32" />
<Icon icon="bi:house" width="32" height="32" />
{/* Custom styling */}
<Icon
icon="heroicons:heart"
width="48"
height="48"
style={{ color: "#ef4444" }}
/>
</div>
)
}
Type-Safe Icon Button
import { FC, SVGProps } from 'react'
type IconType = FC<SVGProps<SVGSVGElement>>
interface IconButtonProps {
icon: IconType
label: string
variant?: 'primary' | 'secondary' | 'ghost'
size?: 'sm' | 'md' | 'lg'
onClick?: () => void
}
const sizeMap = {
sm: 'w-4 h-4',
md: 'w-5 h-5',
lg: 'w-6 h-6',
}
const variantMap = {
primary: 'bg-blue-500 text-white hover:bg-blue-600',
secondary: 'bg-gray-200 text-gray-900 hover:bg-gray-300',
ghost: 'text-gray-600 hover:text-gray-900 hover:bg-gray-100',
}
export function IconButton({
icon: Icon,
label,
variant = 'ghost',
size = 'md',
onClick,
}: IconButtonProps) {
return (
<button
onClick={onClick}
aria-label={label}
title={label}
className={`
p-2 rounded-lg transition-all
${variantMap[variant]}
`}
>
<Icon className={sizeMap[size]} />
</button>
)
}
Level 3: Advanced Integration
Custom Icon Component
import { forwardRef, SVGProps } from 'react'
interface CustomIconProps extends SVGProps<SVGSVGElement> {
isActive?: boolean
tooltip?: string
}
export const CustomIcon = forwardRef<SVGSVGElement, CustomIconProps>(
({ isActive, tooltip, className = '', ...props }, ref) => (
<svg
ref={ref}
viewBox="0 0 24 24"
width="24"
height="24"
className={`
${isActive ? 'text-blue-500' : 'text-gray-400'}
${tooltip ? 'cursor-help' : ''}
${className}
transition-colors duration-200
`}
title={tooltip}
{...props}
>
<path d="M12 2C6.48 2 2 6.48 2 12s4.48 10 10 10 10-4.48 10-10S17.52 2 12 2z" />
</svg>
)
)
Icon Theme System
import { Heart, Settings } from 'lucide-react'
type IconTheme = 'light' | 'dark' | 'accent'
interface IconThemeConfig {
color: string
strokeWidth: number
opacity: number
}
const themeConfig: Record<IconTheme, IconThemeConfig> = {
light: { color: '#e5e7eb', strokeWidth: 2, opacity: 1 },
dark: { color: '#1f2937', strokeWidth: 2, opacity: 1 },
accent: { color: '#0ea5e9', strokeWidth: 2.5, opacity: 1 },
}
export function ThemedIcon({ theme, size = 24 }: { theme: IconTheme; size?: number }) {
const config = themeConfig[theme]
return (
<div className="flex gap-4">
<Heart size={size} color={config.color} strokeWidth={config.strokeWidth} />
<Settings size={size} color={config.color} strokeWidth={config.strokeWidth} />
</div>
)
}
Icon Animation
import { Heart } from 'lucide-react'
import { useState } from 'react'
export function AnimatedIcon() {
const [isActive, setIsActive] = useState(false)
return (
<button onClick={() => setIsActive(!isActive)} className="p-4">
<Heart
size={32}
className={`
text-red-500 transition-all duration-300
${isActive ? 'scale-125 animate-pulse' : 'scale-100'}
`}
fill={isActive ? '#ff0000' : 'none'}
/>
</button>
)
}
Performance & Best Practices
Performance Optimization
import { Heart, Star } from 'lucide-react'
import * as Icons from 'lucide-react'
const Icon = Icons[iconName]
const LazyIcon = React.lazy(() => import('lucide-react').then(module => ({
default: module[iconName]
})))
const MemoHeart = React.memo(Heart)
Bundle Optimization Strategies
- Choose right library size: Use Radix Icons for minimal bundles
- Import specific icons: Avoid
import * patterns
- Dynamic loading: Load icons on-demand for large sets
- Icon subsets: Create custom bundles per feature
- Tree-shaking: Use ES modules and bundler optimization
Accessibility Essentials
- ✅ Use
aria-label for icon-only buttons
- ✅ Ensure 4.5:1 color contrast ratio
- ✅ Support high contrast mode with
currentColor
- ✅ Don't rely on color alone for meaning
- ✅ Use semantic HTML structure
- ✅ Test with screen readers
