TL;DR: Replay reconstructs high-quality, interactive SolidJS components directly from video recordings of UI mockups, enabling rapid prototyping and development.

Stop building UI from static images. The future is dynamic. Converting UI mockups to working code is often a tedious, manual process, prone to errors and misinterpretations. Traditional screenshot-to-code tools offer a limited solution, failing to capture the intended user behavior and interaction flow. This is where behavior-driven reconstruction comes in, and where Replay shines.

Replay: Video-to-Code for SolidJS#

Replay analyzes video recordings of UI mockups to generate high-quality SolidJS components. Unlike traditional tools that rely on static images, Replay understands user behavior and intent by analyzing the dynamic elements within the video. This results in more accurate and functional code generation.

Key Benefits of Using Replay for SolidJS Development:#

  • Rapid Prototyping: Quickly transform UI mockups into interactive SolidJS components, accelerating the prototyping process.
  • Behavior-Driven Reconstruction: Replay captures user interactions and translates them into functional code, ensuring the generated components behave as intended.
  • High-Quality Code: Replay generates clean, well-structured SolidJS code that is easy to understand and maintain.
  • Multi-Page Generation: Replay can handle complex multi-page applications, generating code for entire user flows.
  • Supabase Integration: Seamlessly integrate your SolidJS components with Supabase for backend functionality.
  • Style Injection: Replay can inject styles directly into your components, ensuring a consistent look and feel.

How Replay Works: A Step-by-Step Guide#

Let's walk through the process of converting a UI mockup to a SolidJS component using Replay.

Step 1: Recording Your UI Mockup#

Start by recording a video of your UI mockup. Be sure to demonstrate all the interactions and behaviors you want Replay to capture. This includes button clicks, form submissions, page transitions, and any other relevant user actions.

💡 Pro Tip: Speak clearly while interacting with the mockup. Verbal cues describing the intended behavior can significantly improve Replay's accuracy.

Step 2: Uploading to Replay#

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

Step 3: Reviewing and Refining the Generated Code#

Once the reconstruction is complete, Replay will present you with the generated SolidJS code. Review the code to ensure it accurately reflects the intended behavior and make any necessary adjustments.

typescript
// Example SolidJS component generated by Replay import { createSignal, onMount } from 'solid-js'; function Counter() { const [count, setCount] = createSignal(0); const increment = () => { setCount(count() + 1); }; onMount(() => { console.log('Counter component mounted'); }); return ( <div> <h1>Counter: {count()}</h1> <button onClick={increment}>Increment</button> </div> ); } export default Counter;

📝 Note: Replay's generated code can be further customized and extended to meet your specific requirements.

Step 4: Integrating with Your SolidJS Project#

Copy the generated SolidJS code and integrate it into your project. You can then further customize the component and add any additional functionality.

Replay vs. Traditional Screenshot-to-Code Tools#

The key difference between Replay and traditional screenshot-to-code tools lies in the input and the analysis performed. Screenshot-to-code tools analyze static images, while Replay analyzes video recordings. This allows Replay to capture user behavior and generate more functional code.

⚠️ Warning: While screenshot-to-code tools can be useful for generating basic UI elements, they often fall short when it comes to complex interactions and dynamic behavior.

Addressing Common Concerns#

Code Quality and Maintainability#

Replay is designed to generate clean, well-structured SolidJS code that is easy to understand and maintain. The generated code follows best practices and is designed to be easily customizable.

Accuracy and Reliability#

Replay's accuracy depends on the quality of the video recording. Clear, well-defined interactions will result in more accurate code generation.

Integration with Existing Projects#

Replay generates standard SolidJS components that can be easily integrated into existing projects. The generated code can be customized and extended to meet your specific requirements.

Beyond Basic Components: Advanced Features#

Replay isn't just for simple components. Its advanced features allow you to tackle complex UI challenges:

  • Multi-Page Application Reconstruction: Capture entire user flows across multiple pages, and Replay will generate the necessary routing and component interactions.
  • Supabase Integration: Replay can automatically generate the necessary code to interact with your Supabase database, simplifying backend integration. Imagine recording a user filling out a form, and Replay generating both the SolidJS form component and the Supabase database interaction logic.
  • Product Flow Maps: Replay visualizes the user flow captured in your video, allowing you to understand and optimize the user experience.

🚀 Pro Tip: Use Replay to reverse engineer existing applications. Record yourself using the application, and Replay can generate the SolidJS code, providing a valuable learning tool and a starting point for new projects.

Style Injection for a Consistent Look and Feel#

Maintaining a consistent look and feel across your application is crucial for user experience. Replay simplifies this process with its style injection feature. It can automatically extract styles from the video and inject them into your SolidJS components, ensuring a uniform visual appearance.

This feature works by analyzing the visual elements in the video and identifying the associated styles. Replay then generates the necessary CSS or Styled Components code and integrates it into the generated SolidJS components.

Frequently Asked Questions#

Is Replay free to use?#

Replay offers a free tier with limited functionality. Paid plans are available for users who require more advanced features and higher usage limits. Check the Replay website for the most up-to-date pricing information.

How is Replay different from v0.dev?#

While both Replay and v0.dev aim to accelerate UI development, they differ significantly in their approach. v0.dev uses AI to generate UI components based on text prompts. Replay, on the other hand, uses video analysis to reconstruct UI components based on observed user behavior. This allows Replay to capture complex interactions and generate more functional code. Replay also offers native SolidJS support.

What types of UI mockups can Replay handle?#

Replay can handle a wide range of UI mockups, from simple wireframes to complex interactive prototypes. The more detailed and interactive the mockup, the better Replay will be able to reconstruct it.

Does Replay support other frameworks besides SolidJS?#

Currently, Replay is focused on providing first-class support for SolidJS. Support for other frameworks may be added in the future.
