Replay's Customization: Tailoring AI-Generated Code to Your Needs

TL;DR: Replay allows you to customize AI-generated code from video recordings to perfectly match your existing codebase and design system, offering unprecedented control and efficiency.

Level Up Your Workflow: Replay's Customization Options#

The promise of AI-powered code generation is tantalizing: turn ideas into reality faster than ever before. However, the reality often falls short. AI-generated code can be generic, inconsistent with your existing style, and require significant manual tweaking. This is where Replay shines.

Replay isn't just another screenshot-to-code tool. We analyze video recordings of user behavior, using Behavior-Driven Reconstruction, powered by Gemini, to understand intent. This allows us to generate more accurate and functional code. But accuracy is only half the battle. True power lies in customization. Replay offers a suite of features to tailor the generated code to your exact needs, seamlessly integrating it into your existing projects.

Understanding Behavior-Driven Reconstruction#

Traditional screenshot-to-code tools only see the visual output. Replay, on the other hand, understands actions. By analyzing video, Replay can discern:

• •User clicks and interactions
• •Page transitions and navigation flows
• •Data input and form submissions
• •Animations and dynamic elements

This understanding allows Replay to generate code that replicates not just the look and feel, but also the behavior of the recorded UI.

Why Customization Matters#

Imagine generating a complex multi-page application with a single video. Without customization, you're likely facing:

• •Inconsistent styling: The generated code might use different naming conventions, CSS classes, or styling approaches than your existing codebase.
• •Integration challenges: The generated components might not seamlessly integrate with your existing framework or library.
• •Maintenance overhead: Manually refactoring the generated code to match your standards can be time-consuming and error-prone.

Replay addresses these challenges head-on with robust customization options.

Replay's Customization Arsenal#

Replay provides several powerful features to tailor the generated code to your exact specifications:

• •Style Injection: Import your existing CSS or Tailwind configuration to ensure consistent styling.
• •Component Mapping: Map generated components to your existing UI library (e.g., Material UI, Ant Design).
• •Naming Conventions: Define custom naming conventions for components, variables, and CSS classes.
• •Supabase Integration: Seamlessly integrate with your Supabase backend, including authentication and data fetching.
• •Multi-Page Generation: Reconstruct entire application flows from a single video.

Let's dive into each of these features with practical examples.

Style Injection: Maintaining Visual Harmony#

One of the biggest challenges with AI-generated code is ensuring consistent styling. Replay's style injection feature allows you to import your existing CSS or Tailwind configuration, ensuring that the generated code adheres to your design system.

typescript
// Example: Injecting a Tailwind configuration

const replayConfig = {
  styleInjection: {
    type: 'tailwind',
    configPath: './tailwind.config.js',
  },
};

This configuration tells Replay to use your

file to style the generated components. Replay intelligently applies your Tailwind classes to ensure visual consistency.

💡 Pro Tip: For more complex styling setups, consider using CSS variables and importing your custom CSS file.

Component Mapping: Bridging the Gap#

Replay allows you to map generated components to your existing UI library. This ensures that the generated code uses the components you're already familiar with, simplifying integration and maintenance.

typescript
// Example: Mapping a generated button to a Material UI Button

const replayConfig = {
  componentMapping: {
    'Button': '@mui/material/Button',
  },
};

This configuration tells Replay to replace any generated

component with the component.

📝 Note: Component mapping requires a clear understanding of your UI library's API and component structure.

Naming Conventions: Enforcing Consistency#

Consistent naming conventions are crucial for maintainability. Replay allows you to define custom naming conventions for components, variables, and CSS classes.

typescript
// Example: Defining a custom naming convention for components

const replayConfig = {
  namingConventions: {
    component: (name: string) => `My${name}`,
    variable: (name: string) => `${name}Value`,
    cssClass: (name: string) => `my-${name}`,
  },
};

This configuration tells Replay to prefix all component names with "My", append "Value" to variable names, and prefix CSS classes with "my-".

Supabase Integration: Powering Your Backend#

Replay seamlessly integrates with Supabase, allowing you to generate code that interacts with your Supabase backend, including authentication and data fetching.

⚠️ Warning: Ensure your Supabase API keys are properly secured and never exposed in client-side code.

Replay can automatically generate the necessary API calls and data bindings to connect your UI to your Supabase database. Simply provide your Supabase credentials and Replay will handle the rest.

Multi-Page Generation: Building Complex Flows#

Replay's ability to generate code for multi-page applications from a single video is a game-changer. This feature allows you to reconstruct entire application flows, including navigation, data input, and form submissions.

Replay analyzes the video to understand the relationships between different pages and generates the necessary routing and navigation logic.

Real-World Example: Rebuilding a To-Do App#

Let's walk through a practical example of using Replay to rebuild a simple to-do app. We'll start with a video recording of a user interacting with an existing to-do app.

Step 1: Upload the Video to Replay#

Upload the video recording to Replay. Replay will analyze the video and generate a preliminary code structure.

Step 2: Configure Style Injection#

Import your Tailwind configuration to ensure consistent styling.

typescript
// tailwind.config.js
module.exports = {
  theme: {
    extend: {
      colors: {
        primary: '#3490dc',
        secondary: '#ffed4a',
      },
    },
  },
};

typescript
// Replay configuration
const replayConfig = {
  styleInjection: {
    type: 'tailwind',
    configPath: './tailwind.config.js',
  },
};

Step 3: Map Components to Your UI Library#

Map the generated button and input components to your preferred UI library (e.g., Material UI).

typescript
// Replay configuration
const replayConfig = {
  componentMapping: {
    'Button': '@mui/material/Button',
    'Input': '@mui/material/TextField',
  },
};

Step 4: Integrate with Supabase#

Configure Replay to connect to your Supabase backend.

typescript
// Replay configuration
const replayConfig = {
  supabase: {
    url: 'YOUR_SUPABASE_URL',
    apiKey: 'YOUR_SUPABASE_API_KEY',
  },
};

Step 5: Generate the Code#

Generate the code. Replay will use your configuration to produce code that seamlessly integrates with your existing project.

Result#

The generated code will include:

• •Properly styled components using your Tailwind configuration.
• •Mapped components from your UI library.
• •Seamless integration with your Supabase backend for data storage and retrieval.

Comparison: Replay vs. Traditional Methods#

Code Example: Generated React Component#

Here's an example of a generated React component with style injection and component mapping:

typescript
// Generated React component

import React from 'react';
import { Button, TextField } from '@mui/material';

const MyTodoItem = ({ task, onComplete }) => {
  return (
    <div className="my-todo-item">
      <TextField value={task} className="my-task-input" />
      <Button onClick={onComplete} className="my-complete-button">
        Complete
      </Button>
    </div>
  );
};

export default MyTodoItem;

This component uses Material UI components and applies custom CSS classes (prefixed with "my-") as defined in the configuration.

Benefits of Replay's Customization#

• •Increased Efficiency: Generate code faster and with less manual tweaking.
• •Improved Consistency: Ensure consistent styling and component usage across your project.
• •Simplified Integration: Seamlessly integrate generated code into your existing codebase.
• •Reduced Maintenance: Minimize the need for manual refactoring and maintenance.
• •Enhanced Collaboration: Facilitate collaboration between designers and developers.
