Angular error handling Pandiyan Murugan - 29-Jan-22 Best practices
Backstory of an error • Complexity of application • Communication
between stakeholders • Developer mistakes • Time pressure • Lack of testing
catch?
None
Catch them all • Angular provides a hook for centralized
exception handling with ErrorHandler. • However, the default implementation of ErrorHandler only prints error messages to the console. We can modify later.
• Then, we provide it in our root module to
change default behavior in our application. Instead of using the default ErrorHandler class we are using our class
Errors • Client side errors • Server side errors •
Error service
HttpInterceptor • HttpInterceptor was introduced with Angular 4.3.1. It provides
a way to intercept HTTP requests and responses to transform or handle them before passing them along. •
Demo • https://stackblitz.com/edit/angular-ivy-mym3tm? file=src%2Fapp%2Fapp.component.ts
