Component Storybook Generation from Video Walkthroughs

TL;DR: Replay enables rapid Component Storybook generation directly from video walkthroughs, accelerating UI development and design consistency.

Stop Building Storybooks Manually: The Power of Video-to-Code#

Building a comprehensive Storybook for your UI components is crucial for maintainability, collaboration, and visual regression testing. However, the process can be tedious and time-consuming, often involving manual coding of stories for each component state. What if you could simply record a video of your component in action and automatically generate a fully functional Storybook? That's the power of Replay.

Replay uses behavior-driven reconstruction to understand user interactions within the video and translate them into working Storybook stories. Forget static screenshots; Replay analyzes the behavior demonstrated in the video, ensuring accurate and dynamic component representations.

Why Video-Driven Storybook Generation?#

The traditional approach to Storybook creation often relies on developers manually writing stories, which can be:

• •Time-Consuming: Writing stories for every component state takes valuable development time.
• •Error-Prone: Manual story creation is susceptible to human error, leading to inconsistencies.
• •Difficult to Maintain: Keeping Storybooks up-to-date with component changes requires ongoing effort.

Replay offers a paradigm shift by automating the Storybook generation process, reducing manual effort and improving accuracy.

Generating a Component Storybook with Replay: A Step-by-Step Guide#

Let's walk through how to generate a Storybook for a simple React button component using Replay.

Step 1: Record Your Component in Action#

First, record a video demonstrating the different states of your button component:

• •Default state
• •Hover state
• •Click state
• •Disabled state

Ensure the video is clear and showcases all relevant interactions and visual changes.

Step 2: Upload the Video to Replay#

Upload the recorded video to the Replay platform. Replay's AI engine will analyze the video, identify the component, and understand its behavior.

Step 3: Configure Your Storybook Project#

Specify the target directory for your Storybook files and any necessary configuration options. Replay supports seamless integration with existing Storybook projects. You can also specify the Supabase integration details if your component interacts with a Supabase backend.

Step 4: Generate the Storybook#

Click the "Generate Storybook" button. Replay will automatically generate the necessary Storybook files, including:

• •Component definition
• •Story definitions for each identified state
• •Necessary imports and dependencies

Step 5: Review and Refine (Optional)#

Review the generated Storybook to ensure accuracy and completeness. You can manually refine the generated code if needed, adding additional stories or customizing the component's appearance.

typescript
// Example of a generated Storybook story
import React from 'react';
import { Button } from './Button';

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

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

export const Default = Template.bind({});
Default.args = {
  label: 'Click Me',
};

export const Hover = Template.bind({});
Hover.args = {
  label: 'Click Me',
  // Simulate hover state (requires CSS or other styling)
  style: { backgroundColor: 'lightblue' },
};

export const Disabled = Template.bind({});
Disabled.args = {
  label: 'Click Me',
  disabled: true,
};

💡 Pro Tip: Focus on clear and concise video recordings to ensure accurate Storybook generation. Highlight all interactive elements and state changes.

Advanced Features and Customization#

Replay offers several advanced features to customize your Storybook generation process:

• •Multi-Page Generation: Replay can analyze videos spanning multiple pages or screens, allowing you to generate Storybooks for complex workflows.
• •Style Injection: Inject custom styles into your generated components to match your design system.
• •Product Flow Maps: Visualize the user flow captured in your video, providing valuable insights into user behavior.

Replay vs. Screenshot-to-Code Tools#

While screenshot-to-code tools can generate UI code from static images, they lack the behavioral understanding that Replay provides. Replay analyzes the interactions within the video, resulting in more accurate and dynamic component representations.

📝 Note: Replay's "Behavior-Driven Reconstruction" leverages Gemini's powerful video understanding capabilities to create truly interactive and accurate Storybooks.

Integrating Replay with Your Workflow#

Replay integrates seamlessly with existing development workflows and tools:

• •Version Control: Track changes to your generated Storybook files using Git.
• •CI/CD: Automate Storybook generation as part of your CI/CD pipeline.
• •Design Systems: Ensure consistency across your UI components by generating Storybooks from design system videos.

⚠️ Warning: While Replay automates Storybook generation, it's essential to review and refine the generated code to ensure it meets your specific requirements.

typescript
// Example of fetching data from Supabase in a generated component
import { createClient } from '@supabase/supabase-js';

const supabaseUrl = 'YOUR_SUPABASE_URL';
const supabaseKey = 'YOUR_SUPABASE_ANON_KEY';
const supabase = createClient(supabaseUrl, supabaseKey);

const MyComponent = async () => {
  const { data, error } = await supabase
    .from('my_table')
    .select('*');

  if (error) {
    console.error('Error fetching data:', error);
    return <div>Error: {error.message}</div>;
  }

  return (
    <div>
      {data.map((item) => (
        <div key={item.id}>{item.name}</div>
      ))}
    </div>
  );
};

Step 1: Installation#

You'll need to install the Supabase client:

bash
npm install @supabase/supabase-js

Step 2: Configuration#

Configure your Supabase URL and API key within your project. Store these securely using environment variables.

Step 3: Data Fetching#

Use the code snippet above to fetch data from your Supabase database within your component.
