How can I implement error boundaries in React?

You can implement error boundaries in React by creating a class component that defines the static method getDerivedStateFromError and the componentDidCatch lifecycle method.

Can you show me a code example?

Sure! Here's a simple example:

class ErrorBoundary extends React.Component {
  static getDerivedStateFromError(error) {
    return { hasError: true };  
  }

  componentDidCatch(error, info) {
    console.error('Error caught in ErrorBoundary:', error, info);
  }

  render() {
    if (this.state.hasError) {
      return <h1>Something went wrong.</h1>;
    }
    return this.props.children;  
  }
}

What should I wrap with the ErrorBoundary?

You should wrap any component that might throw an error, such as components that fetch data or render user input.
