Interceptors in NestJS provide us many capabilities by intercepting the Request and Response, unlike Middleware which run on Request only. We can bind extra logic before and after Route Handler Method Execution benefiting us from AOP (Aspect-Oriented programming). In addition to that, Interceptors help us to Override Method Behavior, Request Timeouts, and much more.

In this video, we will explore the concept of AOP, Interceptors. Also we will see some use cases like Read-through Cache and Request Timeouts.
