Story Structure and Conventions in Storybook.js

Introduction

Understanding story structure and conventions is crucial for effectively using Storybook.js. This lesson will cover the essential components of story structure and define the conventions you should follow while building storybooks.

Key Concepts

Before diving into the structure, let’s define some key concepts:

• **Story**: A single visual representation of a component. It showcases the component's various states.
• **Component**: A reusable piece of UI that can be combined with other components to create a full interface.
• **Meta**: Metadata that describes the component and its stories.

Story Structure

The structure of a story in Storybook.js typically includes:

1. Import Statements: Import React and the component to be documented.
2. Meta Definition: Define metadata about the component.
3. Story Definitions: Create stories showcasing different states of the component.

Example Story Structure

import React from 'react';
import { Button } from './Button';

export default {
    title: 'Example/Button',
    component: Button,
};

const Template = (args) => ;

export const Primary = Template.bind({});
Primary.args = {
    primary: true,
    label: 'Primary Button',
};

export const Secondary = Template.bind({});
Secondary.args = {
    label: 'Secondary Button',
};
                    

In this example, we define a Button component with two stories: Primary and Secondary.

Best Practices

To create effective stories, consider the following best practices:

• Keep stories focused on a single aspect of the component.
• Use descriptive names for stories that reflect their purpose.
• Document the component's props clearly in the metadata.
• Ensure stories are visually distinct to highlight differences in state.
