Recommendation Summary

| Library | Best For | Bundle Impact | Icon Count | Unique Advantage | |---------|----------|---------------|------------|------------------| | Lucide React | General use, performance-critical apps | Minimal (1-2KB per icon) | 1,000+ | Best tree-shaking, modern | | React Icons | Projects needing multiple icon families | Medium (with tree-shaking) | 15,000+ | All-in-one solution | | Heroicons | Tailwind CSS projects | Minimal | 300+ | Native Tailwind integration | | Phosphor Icons | Design systems needing weight variants | Small-Medium | 1,200+ | 6 weight variants |

Implementation Pattern

Regardless of which library you choose, follow this pattern for consistency:

1// Create an icon wrapper for centralized styling
2import { Home } from 'lucide-react'; // or your chosen library
3
4interface IconProps {
5  size?: number;
6  className?: string;
7}
8
9export const Icon = ({ Icon: IconComponent, size = 24, className }: IconProps & { Icon: any }) => {
10  return <IconComponent size={size} className={cn('transition-colors', className)} />;
11};
12
13// Usage
14<Icon Icon={Home} size={24} className="text-gray-700 hover:text-blue-500" />

This approach allows you to:

Centralize icon styling and behavior
Easily swap icon libraries if needed
Apply consistent transitions and effects
Maintain type safety with TypeScript
