Storybook is an open-source tool for developing UI components in isolation for React, Vue, and Angular applications. Readers can learn about component-driven development, UI testing, and design systems. With documentation, tutorials, and community contributions, Storybook offers  guidance and tools for building modular and reusable UI components.

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.

Storybook is going ESM-only

Long overdue but a good step. I hope they modularize their product in the upcoming versions to reduce the package size of their bloated all-in-one suite even more. 70-80% should be easily achievable.

So happy to hear, such a good choice! I love Storybook.

This is good. I just started a project using Storybook.
