Publishing a React component to npm is the gold standard for sharing reusable UI logic across projects or with the developer community. With over 25 years of experience in software development and as the creator of CoreUI, I’ve built and published hundreds of packages that power thousands of applications worldwide. The most efficient and modern approach involves bundling your component using a tool like Rollup to support both ESM and CommonJS formats while managing dependencies correctly. This ensures your library is lightweight, tree-shakeable, and compatible with various build environments like Vite, Next.js, or Webpack.
