Catching React Render Errors with OOP Class Error Boundaries

import React, { Component } from 'react';
 
export class SafeErrorBoundary extends Component {
  constructor(props) {
    super(props);
    this.state = { hasError: false, errorDetails: '' };
  }
 
  static getDerivedStateFromError(error) {
    return { hasError: true, errorDetails: error.message };
  }
 
  componentDidCatch(error, errorInfo) {
    console.error('Captured runtime error in child subtree:', error, errorInfo);
  }
 
  render() {
    if (this.state.hasError) {
      return (
        <div role="alert" className="error-fallback">
          <h2>Something crashed</h2>
          <pre>{this.state.errorDetails}</pre>
        </div>
      );
    }
    return this.props.children;
  }
}
