A reusable error boundary component for handling React errors gracefully

Code

class ErrorBoundary extends React.Component<
  { children: React.ReactNode },
  { hasError: boolean }
> {
  constructor(props) {
    super(props)
    this.state = { hasError: false }
  }

  static getDerivedStateFromError(error) {
    return { hasError: true }
  }

  componentDidCatch(error, errorInfo) {
    console.error('Error caught by boundary:', error, errorInfo)
  }

  render() {
    if (this.state.hasError) {
      return <div>Something went wrong. Please try again.</div>
    }

    return this.props.children
  }
}
