NEXr Transformer

Overview

NEXr Transformer is an intelligent code transformation service that leverages AI to analyze, transform, and modernize your codebase. Designed for developers and development teams, it automates complex code refactoring, migration, and enhancement tasks that would traditionally require significant manual effort.

Why NEXr Transformer?

Traditional Code Transformation Challenges

• Time-Consuming: Manual code refactoring takes weeks or months
• Error-Prone: Human errors during large-scale transformations
• Inconsistent: Different developers apply different patterns
• Expensive: Requires senior developers for complex migrations

The NEXr Transformer Solution

• Speed: Automated transformations in minutes instead of weeks
• Accuracy: AI-powered analysis ensures consistent transformations
• Intelligence: Understands code context and intent
• Scalability: Process entire codebases at once
• Integration: Seamless integration with development workflows

Example Transformations

JavaScript to TypeScript

Before:

function calculateTotal(items) {
  return items.reduce((sum, item) => sum + item.price, 0);
}

After:

function calculateTotal(items: Array<{ price: number }>): number {
  return items.reduce((sum, item) => sum + item.price, 0);
}

React Class to Functional Component

Before:

class Counter extends React.Component {
  constructor(props) {
    super(props);
    this.state = { count: 0 };
  }

  increment = () => {
    this.setState({ count: this.state.count + 1 });
  }

  render() {
    return <button onClick={this.increment}>{this.state.count}</button>;
  }
}

After:

const Counter: React.FC = () => {
  const [count, setCount] = useState(0);

  const increment = useCallback(() => {
    setCount(prev => prev + 1);
  }, []);

  return <button onClick={increment}>{count}</button>;
};
