How to Convert a Video of an Interface Into a SolidJS Component Using Replay AI

TL;DR: Replay empowers you to convert video recordings of user interfaces into fully functional SolidJS components, leveraging behavior-driven reconstruction for accurate and maintainable code.

The Holy Grail: Video to Code That Actually Works#

The promise of AI-powered code generation is tantalizing. But the reality often falls short. Screenshot-to-code tools produce static, un-interactive mockups. They miss the crucial element: user intent. What was the user trying to do? That's where Replay shines.

Replay uses a revolutionary video-to-code engine powered by Gemini to reconstruct working UI from screen recordings. It's not just about pixels; it's about understanding behavior. This "Behavior-Driven Reconstruction" makes Replay unique and powerful. Forget static images; Replay uses video as the source of truth.

Why SolidJS?#

SolidJS offers a compelling alternative to React and Vue, boasting fine-grained reactivity and excellent performance. Its simplicity and efficiency make it a fantastic choice for building modern UIs. Converting video of existing interfaces into SolidJS components streamlines development, allowing you to rapidly prototype and iterate on ideas.

Replay: A Deep Dive#

Replay offers a suite of features designed to accelerate UI development:

• •Multi-page generation: Reconstruct entire application flows, not just single screens.
• •Supabase integration: Seamlessly connect your generated components to your Supabase backend.
• •Style injection: Maintain consistent styling across your application with automatically injected styles.
• •Product Flow maps: Visualize user journeys and understand how different components interact.

Here's how Replay stacks up against other code generation tools:

💡 Pro Tip: The quality of your video input directly impacts the accuracy of the generated code. Ensure clear visuals and consistent user actions for optimal results.

Converting a Video to a SolidJS Component: A Step-by-Step Guide#

Let's walk through the process of converting a video of an interface into a functional SolidJS component using Replay.

Step 1: Record Your Interface#

Record a video of the interface you want to convert. Focus on demonstrating the key interactions and functionality. Speak clearly as you navigate, describing what you're doing. For example, if you are demonstrating a login form, record yourself entering credentials and submitting the form.

📝 Note: Replay works best with videos that showcase clear user flows and interactions.

Step 2: Upload to Replay#

Upload your video to the Replay platform. Replay's AI engine will begin analyzing the video, identifying UI elements, and understanding user behavior.

Step 3: Review and Refine#

Once the analysis is complete, Replay will present you with a generated SolidJS component. Review the code and make any necessary adjustments. You can refine the component's structure, styling, and functionality directly within the Replay editor.

Step 4: Integrate into Your Project#

Download the generated SolidJS component and integrate it into your project. You can use it as a starting point for building new features or as a way to quickly prototype existing interfaces.

Example: A Simple Counter Component#

Let's say you recorded a video of a simple counter component with increment and decrement buttons. Here's the SolidJS code Replay might generate:

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>
      <button onClick={decrement}>-</button>
      <span>{count()}</span>
      <button onClick={increment}>+</button>
    </div>
  );
}

export default Counter;

This code is fully functional and ready to be integrated into your SolidJS application. Replay automatically identifies the buttons, the display element, and the associated event handlers.

Step 5: Connecting to Supabase (Optional)#

If your video showcases interactions with data, Replay can help you connect your component to a Supabase backend. Replay analyzes the video to understand how data is being used and generates the necessary API calls and data bindings. You'll need to provide your Supabase credentials and schema.

⚠️ Warning: Ensure you have properly configured your Supabase project and have the necessary permissions to access your data.

Replay can generate code similar to this:

typescript
import { createSignal, createEffect } from 'solid-js';
import { createClient } from '@supabase/supabase-js';

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

function DataComponent() {
  const [data, setData] = createSignal([]);

  createEffect(async () => {
    const { data: results, error } = await supabase
      .from('your_table')
      .select('*');

    if (error) {
      console.error('Error fetching data:', error);
    } else {
      setData(results);
    }
  });

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

export default DataComponent;

This example demonstrates how Replay can automatically generate the code needed to fetch data from a Supabase table and display it in a SolidJS component. The

hook ensures that the data is fetched whenever the component is mounted.

Advanced Use Cases#

Replay isn't limited to simple components. It can handle complex scenarios, including:

• •Form validation: Replay can identify form fields and generate validation logic based on user input.
• •Conditional rendering: Replay can understand how the UI changes based on different conditions and generate the corresponding code.
• •Animations: Replay can detect animations and transitions and generate the necessary CSS or JavaScript code.

Benefits of Using Replay#

• •Faster Prototyping: Quickly convert ideas into working prototypes without writing code from scratch.
• •Improved Collaboration: Share videos of interfaces with your team and generate code that everyone can understand.
• •Reduced Development Time: Automate repetitive tasks and focus on building core functionality.
• •Enhanced Accuracy: Behavior-driven reconstruction ensures that the generated code accurately reflects user intent.
• •Cross-Platform Compatibility: Generate code for SolidJS, React, and Vue, allowing you to target multiple platforms with a single video recording.

Frequently Asked Questions#

Is Replay free to use?#

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

How is Replay different from v0.dev?#

While both tools aim to generate code, Replay uses video as input and focuses on understanding user behavior. v0.dev primarily uses text prompts and generates React code. Replay supports multiple frameworks (SolidJS, React, Vue) and offers deeper integration with Supabase.

What type of videos work best with Replay?#

Videos with clear visuals, consistent user actions, and minimal background noise work best. It's helpful to narrate your actions while recording.

Can Replay handle complex animations?#

Replay can detect and generate code for basic animations and transitions. More complex animations may require manual adjustments.

What frameworks does Replay support?#

Currently, Replay supports SolidJS, React, and Vue. Additional framework support is planned for the future.
