Leveraging Toaster Notifications in AngularJS for Custom Exception Management and Logging

Implemented the use of AngularJS Toaster for effective notification handling.

To customize exception handling, set up in index.html as shown below

<toaster-container toaster-options="{'time-out': 3000, 'position-class': 'toast-top-right'}"></toaster-container>

Utilizing it within a controller like this to handle custom exceptions

myService.serviceName().then(function (data) {
    //perform some tasks
    }).catch(function (error) {
    toaster.pop({
        type: 'error',
        title: 'Custom exception!'
    });
});

How do I integrate Angularjs-Toaster in the $exceptionHandler decorator?
What is the approach to leverage Angularjs-Toaster for logging specific errors?
Is there a way to utilize a shared service for toaster notifications covering success, error, and other messages?

AngularJS comes equipped with its own exception handler, which can be customized using a Decorator to extend the capabilities of an object within AngularJS.

To integrate toastr messages into a custom exception handler, modify your service to throw exceptions that are caught and handled by the custom exception handler.

Update your service code as follows:

myService.serviceName().then(function (data) {

    // Handle success

}).catch(function (error) {

    // Throw exception from catch handler
    throw new Error(error.msg);

});

Create a Custom Exception Handler for displaying toastr messages:

angular.module('exceptionHandlingApp')
     .config(function($provide) {
         $provide.decorator('$exceptionHandler', 
             ['$delegate', 'toastr', function extendExceptionHandler($delegate, toastr) {
                  return function (exception, cause) {
                       exception.message = '[Error: ]' + exception.message;

                       // Utilize toastr service to display toastr message.

                       toastr.pop({
                          type: 'error',
                          title: exception.message
                       });

                       $delegate(exception, cause);
                  };
            }]);
     });

                       $delegate(exception, cause);
                  };
            }]);
     });
