Replay: Radix UI React Components from Video Examples

TL;DR: Replay lets you reconstruct Radix UI React components directly from video recordings, bridging the gap between visual design and functional code with behavior-driven reconstruction.

Stop staring at design mockups and start building. We've all been there: a beautiful design, a complex interaction, and the daunting task of translating it all into React components, especially when using a component library like Radix UI. Screenshot-to-code tools offer a limited solution, often missing crucial behavioral nuances. What if you could simply record the interaction and have the code generated for you?

Enter Replay.

Replay: Behavior-Driven Radix UI Component Generation#

Replay isn't just another screenshot-to-code tool. It's a video-to-code engine powered by Gemini that understands user behavior and reconstructs working UI components from screen recordings. This "Behavior-Driven Reconstruction" approach uses the video as the source of truth, capturing the intricacies of user interactions and translating them into functional React code with Radix UI.

Why Video is Superior to Screenshots#

Screenshots provide a static view of the UI. They don't capture animations, state changes, or complex interactions. Video, on the other hand, tells a story. It reveals the user's intent and the dynamic behavior of the UI. Replay leverages this rich data to generate more accurate and functional code.

Building Radix UI Components with Replay: A Step-by-Step Guide#

Let's walk through a practical example of using Replay to generate a Radix UI React component from a video recording. We'll focus on a simple modal component with an open/close animation.

Step 1: Capture the Video#

Record a video of yourself interacting with the modal. Ensure the video clearly shows:

• •The initial state of the page (modal closed)
• •The action that triggers the modal to open (e.g., clicking a button)
• •The modal opening animation
• •The content of the modal
• •The action that triggers the modal to close (e.g., clicking a close button)
• •The modal closing animation

💡 Pro Tip: A clean, well-defined video is crucial for accurate code generation. Minimize distractions and extraneous movements in the recording.

Step 2: Upload to Replay#

Upload the video to the Replay platform. Replay will analyze the video and begin the reconstruction process.

Step 3: Review and Refine the Generated Code#

Once the analysis is complete, Replay will present you with the generated React code, leveraging Radix UI components. Here's an example of what the generated code might look like:

typescript
// Example generated by Replay
import * as React from 'react';
import * as Dialog from '@radix-ui/react-dialog';
import { styled } from '@stitches/react';

const StyledOverlay = styled(Dialog.Overlay, {
  backgroundColor: 'rgba(0, 0, 0, 0.5)',
  position: 'fixed',
  top: 0,
  left: 0,
  right: 0,
  bottom: 0,
  display: 'grid',
  placeItems: 'center',
});

const StyledContent = styled(Dialog.Content, {
  backgroundColor: 'white',
  padding: '20px',
  borderRadius: '8px',
  boxShadow: '0px 10px 38px -10px rgba(22, 23, 24, 0.35)',
  width: '90vw',
  maxWidth: '500px',
  maxHeight: '85vh',
  position: 'fixed',
  top: '50%',
  left: '50%',
  transform: 'translate(-50%, -50%)',
  '&:focus': { outline: 'none' },
});

const StyledTitle = styled(Dialog.Title, {
  margin: 0,
  fontWeight: 500,
  fontSize: '17px',
});

const StyledDescription = styled(Dialog.Description, {
  margin: '10px 0 20px',
  color: '#787878',
  fontSize: '15px',
  lineHeight: '1.5',
});


const Modal = () => {
  const [open, setOpen] = React.useState(false);

  return (
    <Dialog.Root open={open} onOpenChange={setOpen}>
      <Dialog.Trigger asChild>
        <button>Open Modal</button>
      </Dialog.Trigger>
      <StyledOverlay />
      <StyledContent>
        <StyledTitle>My Modal Title</StyledTitle>
        <StyledDescription>
          This is the modal description.
        </StyledDescription>
        <Dialog.Close asChild>
          <button>Close</button>
        </Dialog.Close>
      </StyledContent>
    </Dialog.Root>
  );
};

export default Modal;

📝 Note: The generated code is a starting point. You may need to adjust the styling, content, and event handlers to perfectly match your requirements. Replay provides a solid foundation, saving you significant time and effort.

Step 4: Integrate and Customize#

Integrate the generated code into your React project. Customize the styling and functionality as needed. You can leverage Replay's style injection feature to apply your existing CSS or theme to the generated components.

Replay's Key Features for Radix UI Development#

• •Radix UI Component Recognition: Replay is trained to identify and reconstruct Radix UI components, ensuring accurate and efficient code generation.
• •Behavior-Driven Reconstruction: Captures the dynamic behavior of the UI, including animations, state changes, and event handlers.
• •Multi-Page Generation: Reconstructs entire product flows, not just single components.
• •Supabase Integration: Seamlessly integrates with your Supabase backend for data persistence and authentication.
• •Style Injection: Applies your existing CSS or theme to the generated components.
• •Product Flow Maps: Visualizes the user journey and the relationships between different components and pages.

Beyond Basic Components: Complex Interactions#

Replay excels at reconstructing complex interactions that are difficult to capture with static screenshots. Consider a scenario with nested menus, drag-and-drop functionality, or real-time data updates. Replay can analyze the video and generate the necessary code to handle these interactions, saving you countless hours of manual coding.

⚠️ Warning: While Replay strives for accuracy, complex interactions may require additional refinement and testing. Always thoroughly review the generated code and ensure it meets your specific requirements.

Let's say you have a complex form built with Radix UI, including custom validation and error handling. Recording a video of yourself filling out the form and triggering different validation scenarios allows Replay to reconstruct the form with the correct Radix UI components and the associated validation logic.

typescript
// Example of a Radix UI form component generated by Replay
import * as React from 'react';
import { useForm } from 'react-hook-form';
import * as Label from '@radix-ui/react-label';
import * as Input from '@radix-ui/react-input';

const MyForm = () => {
  const { register, handleSubmit, formState: { errors } } = useForm();

  const onSubmit = (data: any) => {
    console.log(data);
  };

  return (
    <form onSubmit={handleSubmit(onSubmit)}>
      <Label.Root htmlFor="name">Name</Label.Root>
      <Input.Root id="name" {...register("name", { required: "Name is required" })} />
      {errors.name && <span>{errors.name.message}</span>}

      <Label.Root htmlFor="email">Email</Label.Root>
      <Input.Root id="email" {...register("email", { required: "Email is required", pattern: { value: /^\S+@\S+$/i, message: "Invalid email address" } })} />
      {errors.email && <span>{errors.email.message}</span>}

      <button type="submit">Submit</button>
    </form>
  );
};

export default MyForm;

Frequently Asked Questions#

Is Replay free to use?#

Replay offers a free tier with limited usage. Paid plans are available for higher usage and access to advanced features.

How is Replay different from v0.dev?#

While both tools aim to generate code from visual inputs, Replay uses video as the primary input and focuses on behavior-driven reconstruction. v0.dev primarily uses text prompts and design specifications. Replay understands how the UI is used, not just what it looks like.

What frameworks and UI libraries does Replay support?#

Replay currently supports React, Next.js, and Radix UI. Support for other frameworks and libraries is planned for future releases.

Can I customize the generated code?#

Yes, the generated code is fully customizable. You can modify the styling, functionality, and event handlers to meet your specific requirements.

How accurate is the generated code?#

The accuracy of the generated code depends on the quality of the video and the complexity of the UI. Replay strives for high accuracy, but complex interactions may require additional refinement.

What if the generated code doesn't work perfectly?#

Replay provides a solid foundation, saving you significant time and effort. Use the generated code as a starting point and refine it as needed. The platform also offers debugging tools to help you identify and fix any issues.
