Показать описание
Unfortunately, errors happen in every application which makes error handling in angular apps one of the most critical parts you have to focus on. Yes, we can't get rid of errors completely, however, we can react to them and gracefully handle exceptions improving the user experience in our apps. In this video, I will share with you different error handling strategies in Angular that will help you to solve 80% of possible scenarios that might occur in your angular applications. You will learn how to handle exceptions that happen in sync and async code, how Angular tracks errors, and how it globally handles it. You will see how errors are being handled by rxjs streams and how to use Angular HTTP_INTERCEPTORS to implement a global strategy for failed HTTP requests.
