LICENSING & COMMERCIAL USE DEEP-DIVE

PERFORMANCE & BUNDLE SIZE

Modern front-end frameworks like React and Next.js heavily penalize large JavaScript bundles. This makes tree-shaking—the ability of a bundler to remove unused code—a crucial factor when choosing between Octicons and Simple Icons.

  • Octicons Performance: Because Octicons supports tree-shaking, importing a single icon will only add a tiny fraction of a kilobyte to your final bundle. You can safely install the entire package without performance concerns.
  • Simple Icons Performance: Similarly, Simple Icons is fully tree-shakable. Your Webpack or Turbopack build step will strip out any unused icons, ensuring your First Contentful Paint (FCP) metrics remain exceptional.

REACT IMPORT SYNTAX & INTEGRATION

Here is how you actually write the code to import and use each library in a React or Next.js component. Both libraries offer distinct APIs and integration patterns.

Octicons Integration
import { RepoIcon } from '@primer/octicons-react'

export default function App() {
  return <RepoIcon size={16} />
}
Simple Icons Integration
import {
  SiGithub,
  SiVercel,
  SiStripe,
  SiReact,
  SiNextdotjs,
  SiTailwindcss,
} from '@icons-pack/react-simple-icons'
// All components use 'Si' prefix + PascalCase brand name

export function TechStack() {
  return (
    <div className="flex items-center gap-4">
      {/* Use currentColor — inherits from parent */}
      <SiGithub size={24} />
      <SiVercel size={24} />

      {/* Use official brand color */}
      <SiStripe size={24} color="#635BFF" />
      <SiReact size={24} color="#61DAFB" />

      {/* Social links row */}
      <a href="https://github.com" aria-label="GitHub">
        <SiGithub size={20} className="text-gray-600 hover:text-gray-900" />
      </a>
    </div>
  )
}
