Abstract:

Creating a course-selling application using the MERN stack (MongoDB, Express.js, React.js, Node.js) involves developing a robust platform that enables users to purchase and access various online courses. The application architecture is divided into two main parts: the frontend, built with React.js, which handles the user interface and provides a seamless user experience, and the backend, powered by Node.js and Express.js, which manages data transactions and user authentication.
In this application, users can sign up and log in to access features such as browsing a catalog of available courses, filtering them by category, and viewing detailed descriptions and instructor information. Once users find a course of interest, they can securely purchase it, typically integrating a payment gateway like Stripe or PayPal for processing transactions. The application also includes an admin dashboard, allowing administrators to manage course listings, track sales, and oversee user accounts.

Furthermore, the application utilizes MongoDB to store data about courses, user profiles, and purchase history, ensuring a reliable and efficient data management system. By combining these technologies, the course-selling application not only provides a comprehensive learning platform but also ensures a smooth, engaging, and user-friendly experience for both learners and administrators.
