In this Loom, I walk through our core Docbook build using the MERN stack with a server backend and a React frontend. I cover key files, how we initialize Express, connect to MongoDB, set up API routes, and run the server on port 8080. I explain our user module with hashed passwords, the authentication controller that returns JWT tokens, and the appointment controller that prevents double booking and sends confirmation notifications. I also show Axios auth middleware, Redux state persistence, and React Router screens. No specific viewer action was requested.
