`HttpInterceptor` is an interface in Angular that allows you to intercept and modify HTTP requests and responses. By implementing `HttpInterceptor`, you can add custom logic to the request or response pipeline, such as adding authorization headers, logging request details, or handling errors globally. Interceptors are registered with the `HttpClientModule` and can be used to provide cross-cutting concerns that affect multiple HTTP operations throughout the application. This approach helps maintain a clean and consistent handling of HTTP communications.

Angular's `HttpClient` is a service provided by the `@angular/common/http` package that simplifies making HTTP requests and handling responses. It offers a modern, promise-based API for performing CRUD operations and interacting with RESTful services. `HttpClient` supports various methods such as `GET`, `POST`, `PUT`, and `DELETE`, and provides features for handling request and response data, including automatic JSON parsing and error handling. By using `HttpClient`, developers can efficiently manage network communication and integrate external APIs or backend services into their Angular applications.

Django middleware classes are components that process requests and responses globally. Middleware can be used for various tasks such as session management, authentication, or modifying request and response objects. Middleware classes are defined in `MIDDLEWARE` setting and are executed in the order they are listed.

Axios provides built-in error handling with promises. Use the `.catch()` method to capture errors or you can use a `try-catch` block in an async/await function. Axios errors include information such as the request, response, and configuration, making debugging easier. 
 
 axios.get('/user').catch(error => console.log(error));
