Convert InVision Prototypes to React Components with Replay

TL;DR: Replay lets you convert InVision prototypes into fully functional React components by analyzing screen recordings of user interactions, saving you countless hours of manual coding.

From Prototype to Production: Bridging the Gap with Replay#

InVision prototypes are fantastic for visualizing and testing user flows. However, the transition from prototype to a fully functional React application can be a tedious and time-consuming process. Manually translating design specs into code often leads to inconsistencies, missed interactions, and a frustrating development cycle.

This is where Replay changes the game. Instead of relying on static design assets or complex handoff documents, Replay uses video analysis and AI to reconstruct interactive UI components directly from screen recordings of your InVision prototypes. This "Behavior-Driven Reconstruction" approach ensures that your final product accurately reflects the intended user experience.

Why Video? Behavior-Driven Reconstruction Explained#

Most design-to-code solutions rely on static images or design files. This approach struggles to capture the dynamic nature of user interfaces. Replay, on the other hand, uses video as its source of truth. By analyzing screen recordings, Replay understands:

• •User interactions: Clicks, scrolls, form submissions, and more.
• •State changes: How the UI responds to user input.
• •Navigation flows: How users move between different screens and sections.

This behavior-driven approach results in more accurate, functional, and maintainable code. Replay doesn't just generate visual elements; it reconstructs the underlying logic and interactions that make your UI come alive.

Step-by-Step: Converting Your InVision Prototype#

Here's how to convert your InVision prototype into React components using Replay:

Step 1: Record Your Prototype#

1. •Navigate: Open your InVision prototype in your browser.
2. •Record: Use a screen recording tool (like Loom, OBS, or even Replay's built-in recorder). Record yourself interacting with the prototype as a user would. Focus on showcasing all the key interactions and user flows.

   💡 Pro Tip: Plan your recording beforehand. Script the user flow you want to capture to ensure you cover all essential interactions.

Step 2: Upload to Replay#

1. •Create an Account: If you don't already have one, sign up for a Replay account at https://replay.build.
2. •Upload: Upload the screen recording you created in Step 1 to Replay. Replay supports various video formats (MP4, MOV, etc.).

Step 3: Analyze and Configure#

1. •Review: Replay will analyze the video and identify UI elements, interactions, and page transitions.
2. •Configure: Review the analysis and make any necessary adjustments. You can:
   • •Define component boundaries.
   • •Specify data bindings.
   • •Adjust styling options.

   📝 Note: Replay's AI is constantly improving. The more context you provide during configuration, the better the generated code will be.

Step 4: Generate React Code#

1. •Generate: Click the "Generate Code" button. Replay will generate clean, functional React code based on your video and configuration.
2. •Download/Integrate: Download the generated code as a ZIP file, or directly integrate it into your existing React project using Replay's API.

Step 5: Integrate and Customize#

1. •Import: Import the generated components into your React project.
2. •Customize: Customize the components as needed. Replay provides a solid foundation, but you can always add your own styling, logic, and data integrations.

Example: Generating a Simple Button Component#

Let's say your InVision prototype includes a simple button. Here's how Replay would help generate the React code:

1. •Recording: You record yourself clicking the button in the prototype.
2. •Analysis: Replay identifies the button element and the click interaction.
3. •Generation: Replay generates the following React code:

typescript
// Generated by Replay
import React from 'react';

interface ButtonProps {
  onClick: () => void;
  children: React.ReactNode;
  style?: React.CSSProperties;
}

const Button: React.FC<ButtonProps> = ({ onClick, children, style }) => {
  return (
    <button style={{...defaultStyle, ...style}} onClick={onClick}>
      {children}
    </button>
  );
};

const defaultStyle = {
  backgroundColor: '#007bff',
  color: 'white',
  padding: '10px 20px',
  borderRadius: '5px',
  border: 'none',
  cursor: 'pointer'
};

export default Button;

This code provides a functional React button component that you can easily integrate into your project. You can customize the

prop to match your design system.

Beyond the Basics: Advanced Features#

Replay offers several advanced features that can significantly streamline your development workflow:

• •Multi-page Generation: Replay can analyze recordings that span multiple pages or screens, generating complete user flows.
• •Supabase Integration: Seamlessly connect your generated components to your Supabase backend for data persistence and real-time updates.
• •Style Injection: Inject CSS or Tailwind CSS styles directly into your components for consistent styling.
• •Product Flow Maps: Visualize the user flows captured in your recordings to gain a deeper understanding of user behavior.

Benefits of Using Replay#

• •Faster Development: Automate the tedious task of manually coding UI components.
• •Improved Accuracy: Ensure that your final product accurately reflects the intended user experience.
• •Reduced Errors: Minimize the risk of inconsistencies and missed interactions.
• •Enhanced Collaboration: Facilitate communication between designers and developers.
• •Increased Maintainability: Generate clean, well-structured code that is easy to maintain and update.

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. Check the pricing page for details.

How is Replay different from v0.dev?#

While both Replay and v0.dev aim to accelerate UI development, they differ in their approach. v0.dev relies on text-based prompts to generate code, whereas Replay uses video analysis. This allows Replay to capture the nuances of user interaction and generate more accurate and functional code.

What kind of applications is Replay best suited for?#

Replay is ideal for a wide range of applications, including:

• •E-commerce websites
• •SaaS platforms
• •Mobile apps
• •Web applications

What if the generated code isn't perfect?#

Replay is designed to provide a solid foundation, not a perfect solution. You can always customize the generated code to meet your specific needs. The goal is to significantly reduce the amount of manual coding required, not eliminate it entirely.

⚠️ Warning: While Replay significantly reduces development time, it is not a "magic bullet." Review the generated code carefully and make any necessary adjustments to ensure it meets your specific requirements.
