Generating API Docs with Storybook

Storybook is an open-source tool for developing UI components in isolation for React, Vue, and Angular. One of the powerful features of Storybook is the ability to generate documentation for your components, including API documentation.

To get started with generating API docs in Storybook, follow these steps:

1. Install Storybook in your project:

npx sb init

2. Install necessary addons for documentation:

npm install --save-dev @storybook/addon-docs

3. Configure Storybook to use the docs addon by adding it to your main configuration file:

module.exports = {
                    addons: ['@storybook/addon-docs'],
                };

Once you have Storybook and the docs addon installed, you can start creating API documentation for your components.

Here’s how to document your components:

1. Define PropTypes for your component:

import PropTypes from 'prop-types';

                const MyComponent = ({ title, onClick }) => {
                    return <button onClick={onClick}>{title}</button>;
                };

                MyComponent.propTypes = {
                    title: PropTypes.string.isRequired,
                    onClick: PropTypes.func.isRequired,
                };

2. Use JSDoc comments to describe the component:

/**
                 * MyComponent - A simple button component
                 *
                 * @param {string} title - The title of the button
                 * @param {function} onClick - The function to call on button click
                 * @returns {JSX.Element}
                 */

3. Add the component to your stories file:

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

                const Template = (args) => <MyComponent {...args} />;

                export const Primary = Template.bind({});
                Primary.args = {
                    title: 'Click me',
                    onClick: () => alert('Button clicked!'),
                };

Here are some best practices to keep in mind when generating API docs with Storybook:

• Keep your documentation up-to-date with component changes.
• Use descriptive names and comments for props and functions.
• Leverage the power of Storybook’s interactive playground to test props.
• Consider using TypeScript for better type safety and documentation.
