Lesson 4 / 25
Component Composition
Learn how to compose components and test complex component hierarchies in Storybook.
Composing components in stories
You can compose multiple components together in a story to test how they interact. This is especially useful for testing parent-child relationships and data flow.
Composing a list component
Here's how to test a List component with Item children.
import { List, ListItem } from './List';
export default {
component: List,
title: 'Components/List',
};
export const WithItems = () => (
<List>
<ListItem>First item</ListItem>
<ListItem>Second item</ListItem>
<ListItem>Third item</ListItem>
</List>
);
export const Empty = () => <List />;
export const Loading = () => <List loading />;Testing data flow
Stories allow you to test how components handle different data, callbacks, and state changes without running the full application.
Avoid over-composition
Keep composed stories simple and focused. If a story becomes too complex, break it into smaller components.
