Storybook
Frontend workshop for building UI components and pages in isolation with testing and documentation
About Storybook
Storybook is a frontend development environment that enables developers to build, test, and document UI components in isolation. It provides a workshop-like interface where teams can develop components independently from business logic and APIs. The platform captures component states as stories, allowing developers to create reproducible test cases and comprehensive documentation that serves as a single source of truth for UI patterns across projects.
