In this lab, you will set up a complete MERN (MongoDB, Express, React, Node.js) development environment and demonstrate your understanding of web architecture fundamentals. By the end of this lab, you should have multiple tools running and understand the core concepts that underpin modern web development.
MERN is a client–server architecture that uses layered architecture on the backend, middleware pipelines for cross-cutting concerns, MVC-style separation for request handling, and component-based architecture on the frontend.
