The third edition of this course will teach you many useful things about building, testing, and launching Node apps. You will learn to create Express web servers and APIs that use Mongoose or MongoDB for data storage. Finally, you'll get an introduction
You will learn how to create the entire back-end stack from scratch: Node.js, Express, MongoDB and Mongoose. You will build a complete, beautiful and useful application and explore some more advanced concepts.
Express.js is a minimal and flexible Node.js framework for developing web applications. It is built on top of the Connect middleware framework but offers a higher-level API for building web applications than connect. For example, express.js has a built-in view engine that supports both Templating and HTML, and an extensible routing system that can be used to define application routes in a clean and readable manner.
