What Is Storybook?
Storybook UI Development
Storybook is a tool for building and testing UI components in isolation. You create 'stories' that render components with different props and states, creating a living component library that serves as documentation, a testing ground, and a design review tool.
How Storybook Works
Storybook renders your React/Vue/Angular components outside your app. You define stories showing each component's variations (default, loading, error, empty). Designers review components visually. Tests run against stories. New developers browse the component library.
Key Concepts
- Stories — Individual states of a component — default, loading, error, disabled, etc.
- Component Library — A browsable catalog of all your UI components and their variations
Frequently Asked Questions
Do I need Storybook?
For teams building shared component libraries or design systems, yes. For small projects with few reusable components, it's optional overhead.
