Storybook is a frontend development environment that has become the industry standard for component-driven development. It provides a dedicated workspace where developers can build and test UI components in isolation, away from the complexity of full application state and business logic. The platform supports the entire component development lifecycle: from initial creation through testing and documentation. Teams can write stories that capture different component states and edge cases, then use those stories for visual testing, interaction testing, and accessibility audits. The result is a browsable component library that serves as both development environment and living documentation.
