rollup-plugin-node-polyfills automatically includes Node.js core module polyfills for Rollup, enabling front-end projects to use packages with Node.js dependencies without manual configuration. This plugin simplifies browser compatibility by transparently adding shims for modules like fs, path, and util, reducing bundle size when unused. It's ideal for projects migrating from environments with Node.js-specific code or those integrating existing Node.js modules into a browser-based application.
