HTTP Interceptors allow us to intercept HTTP requests and responses in our Angular application. They provide the perfect opportunity and place to handle data-flow related logic.

From adding Authorization headers to our HTTP requests to showing the loading spinner while waiting for the response, we can make use of HTTP Interceptors to do many important tasks such as cache response, retry failed requests, log and time HTTP activities, and show notification of results.

In this talk, we will explore what HTTP Interceptors are, how to set them up, and look at example use cases.
