Description: HTTP interceptors in Angular are middleware that allows developers to inspect and transform HTTP requests and responses before they are sent or after they are received. This functionality is crucial for managing communication between the client and server, as it enables the implementation of features such as authentication, error handling, header modification, and data manipulation. Interceptors are part of Angular’s HttpClient module and are implemented as services that intercept requests and responses through dependency injection. By using interceptors, developers can centralize the logic for handling requests and responses, improving code maintainability and readability. Additionally, interceptors can be chained, allowing multiple transformations to be applied sequentially. This ability to intercept and modify the data flow is fundamental in modern web applications that require efficient and secure communication with APIs and other web services.
