What are the best practices for using Angular interceptors?

When using Angular interceptors, it's important to keep them lightweight, handle errors gracefully, and avoid side effects.

Can you explain how to handle errors in interceptors?

Certainly! You can catch errors in the intercept method and use HttpErrorResponse to manage them effectively.

Should I use multiple interceptors or just one?

It's generally better to use multiple interceptors for different concerns, like logging, authentication, and error handling.

How do I test my interceptors?

You can test interceptors by using Angular's HttpClientTestingModule to mock HTTP requests and responses.
