Description: HTTP interceptors are functions that allow intercepting and modifying HTTP requests and responses in web applications. They are commonly used alongside request handling libraries like Axios and Fetch API. Their main goal is to provide a control point for managing communication between the client and the server, allowing developers to perform tasks such as authentication, error handling, modifying data before it is sent or received, and implementing additional business logic. Interceptors can be configured to act before a request is sent or after a response is received, granting them great flexibility and power in managing HTTP communication. This ability to intercept and modify the flow of data is crucial for creating robust and secure web applications, as it allows handling situations such as session expiration, redirecting unauthenticated users, and transforming data into specific formats. In summary, HTTP interceptors are essential tools in web application development, facilitating a more controlled and efficient interaction with web services.
