Web Development with Node.JS and MongoDB (Video 13)

This video tutorial covers the basics of routing in Express JS, explaining how to define routes using HTTP methods and paths, and how to handle them with callbacks. It discusses the use of different HTTP methods like GET, POST, PUT, and DELETE, and introduces the concept of modular routes using router instances. The video also touches on using middleware and patterns for route paths, and concludes with a brief overview of the next steps, including generating application skeletons and adding user authentication.
