Storybook

Harmony includes Storybook built-in, providing a powerful tool for developing and testing UI components in isolation. Storybook allows you to create and showcase components independently, making it easier to develop, test, and document your UI.

Benefits of Using Storybook in Harmony

  • Isolated Development: Develop components in isolation without running your entire application.
  • Interactive Documentation: Create interactive documentation for your components, making it easier for other developers to understand and use them.
  • Visual Testing: Visually test components to ensure they look and behave as expected.
  • Component Libraries: Build and maintain a library of reusable components.
  • Integration with Testing Tools: Integrate with various testing tools to automate visual regression testing.

Getting Started with Storybook

To get started with Storybook in Harmony, follow these steps:

  1. Install Storybook: Storybook is included in Harmony, so you don't need to install it separately.
  2. Create Stories: Create stories for your components to showcase different states and variations.
  3. Run Storybook: Use the command npm run storybook to start the Storybook server and view your components in the browser.

Creating Stories

Each time you create a component, you can also generate a story for it. This allows you to document and test the component in isolation.

Example Story

// MyComponent.stories.ts
import React from 'react';
import { ComponentStory, Meta } from '@storybook/react';
import MyComponent from './MyComponent';

export default {
  title: 'Components/MyComponent',
  component: MyComponent,
} as Meta;

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

export const Default = Template.bind({});
Default.args = {
  // Add default args here
};

Advanced Storybook Features

Storybook offers a range of advanced features to enhance your development workflow:

  • Addons: Extend Storybook's functionality with addons for accessibility, actions, backgrounds, controls, and more.
  • Docs: Automatically generate documentation for your components using the @storybook/addon-docs addon.
  • Controls: Create interactive controls for your component props to dynamically change their values in the Storybook UI.
  • Actions: Log actions and events triggered by your components to debug and test their behavior.

Conclusion

Storybook is a powerful tool that enhances the development and testing of UI components in Harmony. By leveraging Storybook's features, you can create robust, well-documented, and visually tested components that improve the overall quality of your application.
