...The frontend is a React app that implements routing, protected pages, Redux-style state management, and UI flows such as registration, login, profile creation, and post feeds. It shows end-to-end patterns like form handling, API consumption, error handling, alerts, and deployment-ready configuration. The project is structured as teaching material, making trade-offs explicit and code approachable for newcomers to full-stack development. Learners can use it as a template for their own projects or as a reference for common MERN stack techniques.
