Custom error handling for Angular

Angular 2+ and AngularJS are prominent open-source JavaScript MVC frameworks used predominantly for building single-page applications, where robust error handling is crucial. Both frameworks employ distinct methods for error management; Angular 2+ uses the ErrorHandler class for centralized exception handling, allowing developers to create custom error handlers to enhance functionality beyond the default console logging. AngularJS relies on the $exceptionHandler service to manage uncaught exceptions, which can be extended to gather more context and take additional actions. To improve error monitoring and debugging, integrating tools like Rollbar is recommended, as it captures, groups, and reports errors with rich contextual data, providing developers with insights to quickly resolve issues. Rollbar can be configured in both Angular 2+ and AngularJS applications, allowing for comprehensive error tracking and alert notifications to enhance the reliability of applications by ensuring critical errors are addressed promptly.
