Convert UI Component Libraries to Video Tutorials

TL;DR: Stop writing tedious UI component documentation; leverage Replay to convert your existing component library into interactive video tutorials that demonstrate real-world usage and behavior.

The dirty secret of UI component libraries? Nobody reads the documentation. Developers skim, copy-paste, and then spend hours debugging why the component doesn't quite work as expected in their specific context. Static examples and API references are simply insufficient to convey the nuances of real-world component usage. We need a better way to document and demonstrate UI components.

Enter: Video Tutorials. But creating them is a HUGE time sink. What if you could automatically generate interactive, working code examples from simple screen recordings of your components in action?

That's where Replay comes in.

The Problem with Traditional Component Documentation#

Traditional UI component documentation often relies on static examples and lengthy API descriptions. This approach suffers from several critical flaws:

• •Lack of Context: Static examples often fail to illustrate how a component interacts with other parts of an application or how it handles different data scenarios.
• •Abstraction Gap: API references describe what a component does, but not how to effectively use it in a practical setting.
• •Maintenance Overhead: Keeping documentation up-to-date with evolving component libraries is a constant struggle.
• •Limited Engagement: Let's be honest, reading API docs is boring. Developers are more likely to engage with visual and interactive content.

Consider this common scenario: You're trying to use a complex date picker component. The documentation provides a list of props and methods, but it doesn't show you how to handle edge cases like disabling specific dates or integrating with a form. You end up spending hours trawling through Stack Overflow and GitHub issues, trying to piece together a solution.

The Power of Video: Showing, Not Just Telling#

Video tutorials offer a more engaging and effective way to demonstrate UI components. They allow you to:

• •Show real-world usage: Demonstrate how a component behaves in different scenarios and how it interacts with other elements.
• •Provide visual context: Help developers understand the component's visual appearance and how it can be customized.
• •Walk through complex scenarios: Explain how to handle edge cases and common integration challenges.
• •Reduce cognitive load: Allow developers to learn by watching and doing, rather than just reading and interpreting.

However, creating high-quality video tutorials can be time-consuming and expensive. You need to record demos, write scripts, edit footage, and ensure that the tutorials are kept up-to-date. This is where Replay changes the game.

Replay: Turning Video into Working Code and Interactive Tutorials#

Replay is a video-to-code engine that uses Gemini to reconstruct working UI from screen recordings. Unlike traditional screenshot-to-code tools, Replay understands user behavior and intent, allowing you to generate interactive code examples from simple video demonstrations.

Replay leverages "Behavior-Driven Reconstruction," treating video as the source of truth. This means that the generated code accurately reflects the component's behavior in the recorded demonstration.

Replay offers several key features that make it ideal for converting UI component libraries into video tutorials:

• •Multi-page generation: Replay can generate code for complex, multi-page flows, allowing you to demonstrate how components interact across different screens.
• •Supabase integration: Replay seamlessly integrates with Supabase, allowing you to quickly create backend services for your components.
• •Style injection: Replay can automatically inject styles into the generated code, ensuring that the components look and behave as expected.
• •Product Flow maps: Replay automatically generates flow maps that visualize the user journey through your components, making it easier to understand their behavior.

💡 Pro Tip: Use short, focused video clips to demonstrate specific component features or use cases. This will make the generated code more concise and easier to understand.

Converting Your UI Component Library to Video Tutorials with Replay: A Step-by-Step Guide#

Here's how you can use Replay to convert your existing UI component library into interactive video tutorials:

Step 1: Record Video Demos#

Record short video demos of your components in action. Focus on demonstrating specific features, use cases, or edge cases. Keep the videos concise and to the point. A great starting point is showcasing common props and their effects.

📝 Note: Ensure that the videos are clear and well-lit. Use a screen recording tool that captures mouse movements and keyboard inputs.

Step 2: Upload Videos to Replay#

Upload your video demos to Replay. Replay will automatically analyze the videos and generate working code.

Step 3: Review and Refine the Generated Code#

Review the generated code and make any necessary refinements. Replay provides a visual editor that allows you to easily modify the code and adjust the component's behavior.

⚠️ Warning: While Replay generates high-fidelity code, it's essential to review and test the code thoroughly to ensure that it meets your specific requirements.

Step 4: Integrate with Your Documentation#

Integrate the generated code examples into your UI component library documentation. You can embed the code directly into your documentation pages or create interactive tutorials that allow developers to experiment with the components in a live environment.

Step 5: Add Annotations and Explanations#

Add annotations and explanations to the code examples to provide additional context and guidance. Explain the purpose of each line of code and highlight any important considerations.

Step 6: Iterate and Improve#

Continuously iterate and improve your video tutorials based on user feedback. Add new tutorials to cover additional component features and use cases.

Example: Converting a Button Component#

Let's say you have a button component with different styles (primary, secondary, outlined). You can record a short video demonstrating each style and how it affects the button's appearance and behavior.

Here's an example of the code that Replay might generate from a video of a primary button being clicked:

typescript
// Example generated by Replay
import React from 'react';
import Button from './Button'; // Assuming your button component is in Button.tsx

const PrimaryButtonExample = () => {
  const handleClick = () => {
    alert('Button clicked!');
  };

  return (
    <Button primary onClick={handleClick}>
      Click Me (Primary)
    </Button>
  );
};

export default PrimaryButtonExample;

And here's another example showing how to style a button component using CSS Modules, which Replay can also infer:

typescript
// Example generated by Replay demonstrating CSS Module usage
import React from 'react';
import styles from './Button.module.css'; // CSS Module import

const StyledButtonExample = () => {
  return (
    <button className={styles.myButton}>
      Styled Button
    </button>
  );
};

export default StyledButtonExample;

Replay can also detect and recreate more complex interactions, such as form submissions or data updates. This makes it a powerful tool for documenting components that involve user input or server-side communication.

Benefits of Using Replay#
