{"slug":"webpack-vs-rollup)","title":"Webpack vs Rollup","url":"https://www.aversusb.net/compare/webpack-vs-rollup)","faqCount":5,"faqs":[{"question":"Should I use Webpack or Rollup for my React project?","answer":"Use Webpack for React applications. It provides built-in HMR (critical for React development), automatic code splitting for production, and superior development experience. Rollup is better suited for publishing React component libraries to npm where bundle size optimization matters most."},{"question":"Why is Rollup's bundle size smaller than Webpack's?","answer":"Rollup produces smaller bundles because it uses more aggressive tree-shaking (removing ~85% unused code vs Webpack's ~60%) and doesn't include a runtime chunk. Webpack's runtime adds 20-30KB overhead but enables features like dynamic imports and code splitting. For applications, this trade-off is worthwhile; for libraries, Rollup's minimal output is preferred."},{"question":"Can I use Rollup for a single-page application?","answer":"Technically yes, but it's not recommended. Rollup lacks built-in HMR and automatic code splitting, requiring manual external tool setup (Vite, esbuild). You'd lose productivity gains. Webpack's automatic optimizations make it significantly better for SPA development. Use Rollup only if you absolutely need minimal bundle size over developer experience."},{"question":"How do I set up HMR with Rollup?","answer":"Rollup doesn't natively support HMR. You must use a wrapper like Vite (which uses Rollup for production builds and esbuild for dev), Snowpack, or wmr. For true HMR during development, Webpack remains the standard. If HMR is essential, Webpack is the better choice rather than adding complexity to Rollup."},{"question":"Which bundler do major frameworks recommend?","answer":"React officially recommends Create React App (Webpack-based). Vue recommends Vite (Rollup-based for production). Angular uses Webpack. For libraries, Rollup is standard: React itself, Vue 3, Babel, and TypeScript all use Rollup for npm distribution. Use each tool for its intended purpose: Webpack for apps, Rollup for libraries."}],"faqPageSchema":{"@context":"https://schema.org","@type":"FAQPage","@id":"https://www.aversusb.net/compare/webpack-vs-rollup)#faq","url":"https://www.aversusb.net/compare/webpack-vs-rollup)","inLanguage":"en-US","name":"Webpack vs Rollup — FAQ","description":"Frequently asked questions about Webpack vs Rollup","dateModified":"2026-07-08T10:49:26.472Z","author":{"@type":"Organization","@id":"https://www.aversusb.net/#organization","name":"A Versus B"},"publisher":{"@type":"Organization","@id":"https://www.aversusb.net/#organization","name":"A Versus B"},"isPartOf":{"@type":"Article","@id":"https://www.aversusb.net/compare/webpack-vs-rollup)#article"},"license":"https://creativecommons.org/licenses/by/4.0/","speakable":{"@type":"SpeakableSpecification","cssSelector":["#faq",".faq-item"]},"mainEntity":[{"@type":"Question","name":"Should I use Webpack or Rollup for my React project?","acceptedAnswer":{"@type":"Answer","text":"Use Webpack for React applications.
