How to Convert UX/UI Video to a Production-Ready SolidJS App With Replay AI

TL;DR: Replay AI empowers developers to reconstruct functional SolidJS applications directly from UX/UI screen recordings, leveraging behavior-driven reconstruction for unparalleled accuracy and speed.

The future of UI development isn't about static mockups – it's about understanding user behavior. Stop wasting time hand-coding from design specs and start leveraging the power of video analysis to generate production-ready SolidJS code. Screenshot-to-code tools are a dead end; they capture the what, but miss the why. Replay bridges that gap.

Ditch Static Mockups: Embrace Behavior-Driven Reconstruction#

Traditional UI development workflows are riddled with friction. Designers create mockups, developers interpret them (often incorrectly), and countless hours are lost in translation. This process is fundamentally flawed because it relies on static representations of a dynamic user experience.

Replay flips this paradigm on its head. Instead of starting with a visual representation, we start with a video recording of a user interacting with the intended UI. This video becomes the source of truth, capturing not just the visual elements but also the sequence of actions, the timing of interactions, and the overall user flow.

Replay then uses sophisticated AI, powered by Gemini, to analyze this video and reconstruct a functional SolidJS application. This "behavior-driven reconstruction" ensures that the generated code accurately reflects the intended user experience.

Replay: The Video-to-Code Revolution#

Replay isn't just another screenshot-to-code tool. It's a fundamentally different approach to UI development, built on the principle that video captures the essence of user behavior.

Replay understands the intent behind the user's actions, not just the visual appearance of the UI. This allows it to generate more accurate, more functional, and more maintainable code.

Converting UX/UI Video to SolidJS: A Step-by-Step Guide#

Let's walk through the process of converting a UX/UI video into a production-ready SolidJS application using Replay.

Step 1: Capture the UX/UI Video#

Record a video of a user interacting with the desired UI. This video should showcase the key features and user flows of the application. Ensure the video is clear and well-lit. The more detailed the video, the better Replay can reconstruct the application.

💡 Pro Tip: Narrate the user's actions during the recording. This provides valuable context for Replay's AI engine.

Step 2: Upload to Replay#

Upload the video to the Replay platform. Replay supports various video formats, including MP4, MOV, and AVI.

Step 3: Configure Replay Settings#

Configure the Replay settings to optimize the code generation process. This includes:

• •Target Framework: Select "SolidJS" as the target framework.
• •Supabase Integration: Enable Supabase integration if your application uses Supabase for backend services. Provide your Supabase URL and API key.
• •Style Injection: Choose the desired style injection method (e.g., CSS Modules, Styled Components).
• •Component Naming Convention: Select a naming convention for the generated components (e.g., PascalCase, camelCase).

Step 4: Generate the Code#

Click the "Generate Code" button to initiate the code generation process. Replay will analyze the video, identify the UI elements, and reconstruct the application in SolidJS. This process may take a few minutes, depending on the length and complexity of the video.

📝 Note: Replay uses advanced AI algorithms to ensure the generated code is clean, efficient, and maintainable.

Step 5: Review and Refine the Code#

Once the code generation process is complete, review the generated code in the Replay editor. You can make adjustments to the code, such as:

• •Modifying the UI elements
• •Adding or removing components
• •Adjusting the styling
• •Implementing custom logic

Replay's editor provides a real-time preview of the application, allowing you to see the impact of your changes immediately.

Step 6: Download the SolidJS Project#

Download the generated SolidJS project as a ZIP file. This file contains all the necessary code and assets to run the application.

Step 7: Run the SolidJS Application#

Extract the ZIP file and navigate to the project directory in your terminal. Run the following command to install the dependencies:

bash
npm install

Then, run the following command to start the development server:

bash
npm run dev

This will start the SolidJS application in your browser.

Example Code: A Simple Counter Component#

Here's an example of a simple counter component generated by Replay:

typescript
import { createSignal } from 'solid-js';

function Counter() {
  const [count, setCount] = createSignal(0);

  const increment = () => {
    setCount(count() + 1);
  };

  const decrement = () => {
    setCount(count() - 1);
  };

  return (
    <div>
      <h1>Counter: {count()}</h1>
      <button onClick={increment}>Increment</button>
      <button onClick={decrement}>Decrement</button>
    </div>
  );
}

export default Counter;

This code demonstrates Replay's ability to generate clean, functional SolidJS components from video recordings. The component uses SolidJS's

to manage the counter state and provides buttons to increment and decrement the counter.

Supabase Integration: Backend Made Easy#

Replay seamlessly integrates with Supabase, allowing you to quickly build full-stack SolidJS applications. When generating code, Replay can automatically create Supabase tables and functions based on the data models identified in the video.

⚠️ Warning: Ensure your Supabase URL and API key are configured correctly in the Replay settings.

For example, if the video shows a user creating a new task in a task management application, Replay can automatically generate a Supabase table to store the task data and a Supabase function to handle the task creation logic.

Style Injection: From Basic to Advanced#

Replay supports various style injection methods, allowing you to choose the approach that best suits your needs.

• •CSS Modules: Replay can generate CSS Modules for each component, ensuring that styles are scoped and modular.
• •Styled Components: Replay can generate Styled Components, allowing you to write CSS-in-JS and create reusable styled components.
• •Tailwind CSS: Replay can be configured to generate Tailwind CSS classes, allowing you to leverage the power of utility-first CSS.

Product Flow Maps: Visualize User Journeys#

Replay automatically generates product flow maps based on the user interactions captured in the video. These maps provide a visual representation of the user journey, allowing you to identify potential bottlenecks and areas for improvement.

This feature is invaluable for understanding how users interact with your application and optimizing the user experience.

The Future of UI Development is Here#

Replay is revolutionizing UI development by enabling developers to reconstruct functional applications directly from UX/UI video. This approach saves time, reduces errors, and ensures that the generated code accurately reflects the intended user experience.

By embracing behavior-driven reconstruction, you can unlock the full potential of your UI designs and deliver exceptional user experiences.

Frequently Asked Questions#

Is Replay free to use?#

Replay offers a free tier with limited features. Paid plans are available for users who require more advanced features and higher usage limits.

How is Replay different from v0.dev?#

Replay analyzes video, understanding user behavior and intent, while v0.dev relies on text prompts and generates code based on descriptions. Replay's behavior-driven reconstruction provides more accurate and functional code.

What frameworks does Replay support?#

Currently, Replay supports SolidJS, React, and Vue.js. Support for additional frameworks is planned for future releases.

Can I customize the generated code?#

Yes, Replay provides a powerful editor that allows you to review and refine the generated code. You can make adjustments to the UI elements, add or remove components, adjust the styling, and implement custom logic.
