Description: A response interceptor in Angular is a service that allows intercepting and modifying HTTP responses before they are processed by the requesting component. This mechanism is part of Angular’s HttpClient module and is used to centrally handle the responses of HTTP requests. Interceptors can perform various tasks, such as adding headers, handling errors, transforming data, or even logging information about the responses. By implementing an interceptor, developers can apply common logic to all responses in the application, improving code maintainability and consistency. Additionally, interceptors are easy to implement and can be chained, allowing multiple interceptors to work together to perform complex tasks efficiently. In summary, response interceptors are powerful tools that facilitate the management of HTTP interactions in web applications, allowing for more granular control over data flow and the business logic associated with server responses.
