AngularJS to React AI Conversion

This project demonstrates the conversion of an AngularJS application to React using AI assistance, along with a reusable prompt library for future conversions.

Project Overview

The project includes:

1. Angular PhoneCat: The original AngularJS application (angular-phonecat)
2. React PhoneCat: The converted React application (react-phonecat/)
3. Prompt Library: A collection of reusable prompts for AngularJS to React conversion (prompt-library/)
4. Documentation: Comprehensive documentation of the conversion process (docs/)

AI-Assisted Development

This project was completed using Claude Sonnet 3.7, Anthropic's AI assistant, integrated via a JetBrains IDE plugin. This setup allowed Claude to interact directly with the codebase, providing real-time assistance for code conversion and refactoring. The integration streamlined the AngularJS to React conversion process while maintaining consistent quality throughout the application.

Key Features

• Complete conversion of AngularJS components to React functional components
• Matching visual appearance and animations
• Feature parity with identical user experience
• Comprehensive testing for visual and functional comparison
• Reusable prompt library for future conversions

Prompt Library

The prompt library contains specialized prompts for different aspects of AngularJS to React conversion:

• Component transformation
• Service to hook/context conversion
• Template to JSX conversion
• Data binding transformation
• Routing conversion
• Animation implementation
• Project structure
• Testing strategies

Documentation

The project includes comprehensive documentation:

• Conversion Report - Detailed report on the conversion process
• Testing Guide - Guide for running and analyzing tests
• Lessons Learned - Insights and recommendations from the conversion

Getting Started

Running the React Application

cd react-phonecat
npm install
npm start
# Open http://localhost:3000

Running the AngularJS Application (for comparison)

cd angular-phonecat
npm install
npm start
# Open http://localhost:8000/app/

Running Comparison Tests

cd react-phonecat
npm run test:comparison
npm run test:report  # View the test results

Conversion Results

The conversion achieved:

1. Functional Parity: All features from the original application work identically
2. Visual Matching: The applications look visually identical
3. Time Savings: Approximately 71% reduction in conversion time using the prompt library
4. Code Quality: Modern React patterns and best practices
