Storybook 10 is transitioning to ESM-only builds, eliminating dual CommonJS/ESM support to reduce package size by 15%, simplify maintenance, and align with JavaScript ecosystem standards. The change requires Node.js 20.16+ and valid ESM configuration files, but maintains backward compatibility for most addons. This move follows years of ecosystem preparation and recent Node.js improvements that enable smoother ESM adoption.
