Storybook for design systems: document and test components

Storybook has become the workshop and showroom for component libraries. Engineers use it to build components in isolation, designers use it to review real behaviour, and product teams use it as living documentation. Set up carelessly, though, it becomes a cluttered gallery of outdated examples. This course shows how to use Storybook as the backbone of a design system.

What you will do

Starting from a small React and TypeScript component library, you will add Storybook, write stories in Component Story Format, generate documentation and set up a full testing workflow.

• Stories that cover variants, states and edge cases
• Controls and argTypes that make components explorable
• Autodocs and MDX pages with usage guidance
• Theme switching with decorators and globals
• Interaction tests with play functions
• Accessibility checks with axe and visual regression testing
• A published Storybook deployed automatically from CI

Who should take it

This course is for front end engineers working on shared components and for design technologists who maintain a design system. You should be comfortable with React and basic TypeScript. Designers who review components in Storybook will find the documentation and review sections useful too.

The course uses a current Storybook release with the React and Vite setup. Storybook evolves quickly, so where package names or configuration have changed between major versions I note the difference and link to the official migration guides.
