Storybook

Component workshop

FreeLibraries & build toolingstorybook.js.org

What it is

A sandbox that renders components in isolation with controls for their props, plus docs, accessibility checks and interaction tests. Storybook 10 is ESM-only, roughly 29% lighter, and adds module automocking and first-class Vitest integration.

Why it earns a slot

Lets you build and test a component without clicking through the app to reach it, including error and empty states that are hard to reproduce. Also gives an AI agent a place to verify a component actually renders.

Know before you commit

The heaviest tool here: many dev dependencies, its own build, and stories that rot if nobody maintains them. Major upgrades have been painful, and 10 being ESM-only breaks some older addons.
