How to Convert a Figma Design Walkthrough Video to a Svelte App With Replay AI

TL;DR: Replay converts Figma design walkthrough videos into functional Svelte apps by analyzing user behavior within the video, generating code that mirrors the intended application flow.

Manual UI recreation from design walkthroughs is a soul-crushing task. Hours spent squinting at videos, trying to decipher pixel-perfect placements and reconstruct interactive elements. What if you could automate this entire process, turning video into a working Svelte app? That's where Replay comes in.

Understanding Behavior-Driven Reconstruction#

Replay isn't just another screenshot-to-code tool. It employs behavior-driven reconstruction. This means it analyzes the video of the Figma walkthrough, understanding the sequence of actions, button clicks, and data inputs. It then uses this understanding to generate clean, functional Svelte code.

Think of it this way: screenshot-to-code tools see a static image. Replay sees a user interacting with a design. This fundamental difference allows Replay to create far more robust and accurate applications.

The Power of Replay: From Figma Video to Svelte App#

Replay leverages the power of Gemini to understand the nuances within the video. It identifies UI elements, infers their functionality based on the user's actions, and then generates the corresponding Svelte components. Key features include:

• •Multi-Page Generation: Replay can handle walkthroughs that demonstrate multiple pages or sections of an application.
• •Supabase Integration: Seamlessly integrate your generated app with Supabase for backend functionality.
• •Style Injection: Replay attempts to infer styling from the visual elements in the video, creating a visually consistent application.
• •Product Flow Maps: Replay visually maps the user flow demonstrated in the video, providing a clear overview of the application's structure.

Converting a Figma Walkthrough: A Step-by-Step Guide#

Let's walk through the process of converting a Figma design walkthrough video into a Svelte app using Replay.

Step 1: Prepare Your Figma Walkthrough Video#

The quality of your video directly impacts the quality of the generated code. Keep these tips in mind:

• •Clear Visuals: Ensure the video is well-lit and in focus.
• •Consistent Pacing: Avoid excessively fast or slow movements. A moderate, consistent pace allows Replay to accurately track user actions.
• •Complete Flows: Demonstrate complete user flows, from start to finish.
• •Narration (Optional): While not required, narration can provide additional context that enhances Replay's understanding.

📝 Note: Replay works best with videos that clearly demonstrate the intended user experience. Ambiguous or incomplete walkthroughs may result in less accurate code generation.

Step 2: Upload Your Video to Replay#

Navigate to the Replay platform and upload your Figma walkthrough video. Replay supports various video formats, including MP4, MOV, and AVI.

Step 3: Configure Replay Settings#

After uploading, you'll be presented with several configuration options:

• •Project Name: Give your project a descriptive name.
• •Framework: Select "Svelte" as the target framework.
• •Supabase Integration (Optional): If your design includes backend interactions, configure your Supabase credentials.
• •Style Injection: Enable style injection to automatically apply visual styles to your components.

Step 4: Let Replay Analyze and Generate Code#

This is where the magic happens. Replay will analyze your video, identify UI elements, and generate the corresponding Svelte code. The processing time will vary depending on the length and complexity of the video.

💡 Pro Tip: While Replay is processing, review the documentation to understand the generated code structure and customization options.

Step 5: Review and Refine the Generated Code#

Once the code generation is complete, you'll be able to review the generated Svelte components.

typescript
// Example Svelte component generated by Replay
<script>
  let inputValue = "";

  const handleSubmit = () => {
    alert(`You submitted: ${inputValue}`);
  };
</script>

<input type="text" bind:value={inputValue} placeholder="Enter your name" />
<button on:click={handleSubmit}>Submit</button>

<style>
  input {
    padding: 10px;
    border: 1px solid #ccc;
    border-radius: 5px;
  }

  button {
    background-color: #007bff;
    color: white;
    padding: 10px 20px;
    border: none;
    border-radius: 5px;
    cursor: pointer;
  }
</style>

While Replay strives for accuracy, you may need to make some refinements:

• •Adjust Styling: Fine-tune the CSS to match the original design.
• •Implement Complex Logic: Add any complex logic that Replay couldn't infer from the video.
• •Optimize Performance: Optimize the code for performance, if necessary.

Step 6: Integrate with Your Svelte Project#

Copy the generated Svelte components into your existing Svelte project. Ensure that you have all the necessary dependencies installed.

Step 7: Test and Deploy#

Thoroughly test your application to ensure that it functions as expected. Once you're satisfied, deploy your application to your preferred hosting provider.

Addressing Common Concerns#

• •Accuracy: Replay is not perfect. The accuracy of the generated code depends on the quality of the video and the complexity of the design. Expect to spend some time refining the code.
• •Limitations: Replay may struggle with highly complex animations or custom UI elements that are not easily recognizable.
• •Security: Always review the generated code for potential security vulnerabilities before deploying your application.

⚠️ Warning: Never deploy code generated by any AI tool without thoroughly reviewing it for security vulnerabilities.

Benefits of Using Replay#

• •Significant Time Savings: Automate the tedious task of manually recreating UIs from design walkthroughs.
• •Improved Accuracy: Behavior-driven reconstruction leads to more accurate and functional code.
• •Enhanced Collaboration: Easily share working prototypes with stakeholders.
• •Faster Iteration: Quickly iterate on designs by generating code from updated walkthrough videos.

Frequently Asked Questions#

Is Replay free to use?#

Replay offers a free tier with limited usage. Paid plans are available for higher usage and additional features. Check the Replay website for the latest pricing information.

How is Replay different from v0.dev?#

V0.dev focuses on generating UI components from text prompts. Replay, on the other hand, generates code from video, understanding user behavior and intent to create functional applications. Replay also outputs fully functional Svelte components, not just HTML/CSS.

What video formats does Replay support?#

Replay supports common video formats such as MP4, MOV, and AVI.

Can I use Replay with other frameworks besides Svelte?#

Currently, Replay primarily supports Svelte. Support for other frameworks may be added in the future.

How does Replay handle dynamic data and API integrations?#

Replay attempts to infer API interactions from the video. For more complex scenarios, you may need to manually configure the API integrations in the generated code. The Supabase integration helps simplify this process.
