how to capture errors in a react app code example
Example: react catch error in component
class ErrorBoundary extends React.Component {
constructor(props) {
super(props);
this.state = { hasError: false };
}
componentDidCatch(error, info) { // Display fallback UI this.setState({ hasError: true }); // You can also log the error to an error reporting service logErrorToMyService(error, info); }
render() {
if (this.state.hasError) { // You can render any custom fallback UI return <h1>Something went wrong.</h1>; } return this.props.children;
}
}
