Learn to build the frontend of a full-stack MERN (MongoDB, Express.js, React, Node.js) project in this 35-minute tutorial. Create a React.js application, implement routing with React Router, and structure your project effectively. Explore user stories, make early design decisions, and set up public and nested routes. Dive into file organization, create a dashboard welcome page, and establish routes for notes and users. Review the routing hierarchy and run the completed application to see your MERN stack frontend in action.
