Storybook is a powerful tool for developing and testing UI components in JavaScript. It allows you to create a living style guide that provides a collaborative environment for designers and developers. In this blog post, we will discuss how to write component examples in JavaScript Storybook.

Getting Started

First, make sure you have Storybook installed. Use the following command to install Storybook globally on your machine:

npm install -g @storybook/cli

Next, navigate to your project directory and run the following command to initialize Storybook:

npx -p @storybook/cli sb init

This will create a .storybook directory in your project, along with some initial configuration files.

Writing Component Examples

To write component examples in Storybook, create a .stories.js file for each component you want to showcase.

// Button.stories.js

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

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

export const Primary = () => <Button variant="primary">Primary Button</Button>;

export const Secondary = () => <Button variant="secondary">Secondary Button</Button>;

In the example above, we import the Button component and define a story for it. The title property is used to organize the component within Storybook’s sidebar. The component property specifies the component itself.

Next, we define different stories using the export syntax. Each story is a stand-alone component that showcases the different variations or use cases of the component. In this case, we have Primary and Secondary button examples.

You can also pass props to your component stories. For example:

export const Danger = () => <Button variant="danger">Danger Button</Button>;

Previewing Component Examples

To preview your component examples, run the following command inside your project directory:

npm run storybook

This will start the Storybook server, and you can then access it by opening your browser and navigating to http://localhost:6006.

You will see a list of all your registered component examples, and you can interact with them to view and test their behavior.

Conclusion

Writing component examples in JavaScript Storybook is a great way to visually showcase and test your UI components. By following the steps outlined in this blog post, you will be able to create a living style guide that helps improve collaboration and maintain consistency in your UI development process.
