Course Selling Application

This is a course selling application designed for both administrators and users. It allows users to browse and purchase courses, while administrators can manage courses, users, and other administrative tasks.

Authentication

This application implements role-based authentication using JWT (JSON Web Tokens) and OAuth 2.0 with Google authorization.

• JWT (JSON Web Tokens): JWT is used for securing the communication between the frontend and backend. Upon successful authentication, the backend generates a JWT token, which is then included in subsequent requests from the frontend. The token contains user details and roles, allowing the backend to authorize requests based on user permissions.

• OAuth 2.0 with Google Authorization: Users can also authenticate using OAuth 2.0 with Google. This allows users to log in using their Google accounts, providing a seamless authentication experience.
