How to access the Unhandled Error in AppInsightsErrorBoundary onError prop with Application Insights in React

If you are using TypeScript in your React application and have integrated Application Insights for error tracking, you might have come across the need to access the unhandled error in the AppInsightsErrorBoundary component’s onError prop. In this blog post, we will explore how to achieve this.

The AppInsightsErrorBoundary component is a handy wrapper provided by the Application Insights library that automatically captures and reports unhandled errors in your React application. It can be used as a top-level error boundary to catch and log any unhandled exceptions that occur within its child components.

The onError prop of the AppInsightsErrorBoundary component allows you to provide a callback function that will be called whenever an unhandled error occurs. This callback function receives an Error object as its parameter, which contains information about the error.

Here is an example of how you can access the unhandled error in the onError prop with Application Insights in React:

{`
import React from 'react';
import { AppInsightsErrorBoundary } from '@microsoft/applicationinsights-react-js';

const MyComponent = () => {
  const handleOnError = (error: Error) => {
    // Access the unhandled error here
    console.log('Unhandled error:', error);
    // Perform any additional error handling or logging
  };

  return (
    
      {/* Your application components */}
    
  );
};

export default MyComponent;
`}

In the above example, we define a functional component called MyComponent that wraps its child components with the AppInsightsErrorBoundary component. We provide a callback function handleOnError to the onError prop of the AppInsightsErrorBoundary component.

Inside the handleOnError function, we can access the unhandled error by logging it to the console or performing any other error handling or logging operations as needed.

By utilizing the onError prop of the AppInsightsErrorBoundary component, you can gain more control over how unhandled errors are handled and logged in your React application.

That’s it! You now know how to access the unhandled error in the AppInsightsErrorBoundary component’s onError prop with Application Insights in React. Happy coding!
