What is Storybook?

The essential idea

Storybook is an open-source tool that lets you develop and test UI components in isolation from your main application. It provides a sandbox where you can showcase different states and interactions of a component without running the entire app.

Why use Storybook?

Storybook solves the problem of testing components in isolation. Instead of navigating your app to test each state, you write stories that showcase the component's behavior. This accelerates development, improves documentation, and catches UI bugs early.

Install Storybook

Use the Storybook CLI to scaffold a new Storybook instance in an existing React project.

# For an existing React project
npx storybook@latest init

# This installs Storybook and creates an examples directory with sample stories

Output:

Storybook 7.x installed successfully
