Node.js API Masterclass with Express and MongoDB - Role Authorization

The video tutorial explains how to implement role-based authorization in a Node.js application. It covers creating a middleware function to authorize specific roles, handling errors, and ensuring middleware is executed in the correct order. The tutorial also demonstrates testing the authorization with different user roles using Postman. Finally, it introduces the concept of ownership and permissions for managing boot camps, setting the stage for more advanced access control in future lessons.
