Node & Express API Foundations

Every full-stack app needs a server that stores data and answers the frontend's requests. In this course you will build REST APIs with Node.js and Express, connect them to a PostgreSQL database, validate incoming data, and add simple token-based authentication. Each module ends with your API doing something new and testable. It pairs with the React course in this roadmap to complete the full-stack picture.
