Documenting Components in Storybook

1. Introduction

Storybook is a powerful tool for developing UI components in isolation. Documenting your components helps improve collaboration, maintainability, and usability of your design system.

2. Why Document Components?

• Improves communication among team members.
• Facilitates onboarding of new developers.
• Enhances component reusability.
• Acts as a live style guide for your application.

3. Setting Up Storybook

To start documenting components, ensure you have Storybook installed in your project:

npx sb init

This command will set up Storybook in your project directory. You can then run Storybook using:

npm run storybook

4. Writing Stories

Each UI component can be documented by writing stories. A story is a function that returns a rendered component. Below is an example of a button component:

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: 'Click Me',
};

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

Each story can have various states, allowing developers to visualize different scenarios in which the component can be used.

5. Best Practices

• Document every component with clear descriptions and usage examples.
• Utilize controls and knobs to allow for dynamic interaction with stories.
• Group stories logically to improve navigation.
• Keep stories focused on one variation of the component.
