Mastering Authorization in NestJS: RBAC, Claim-Based, and CASL Examples

This is a comprehensive tutorial on authorization in NestJS! In this video, we'll learn, in practical ways, Role-Based Access Control (RBAC), Claim-based authorization, and fine-grained authorization using CASL.

📌 What You’ll Learn:

Role-Based Access Control (RBAC): Set up and manage roles and permissions efficiently by checking the client(user) roles.
Claim-Based Authorization: Implement authorization based on user claims.
Fine-Grained Authorization with CASL: Leverage CASL to create complex access control rules.

🚀 Why This is Important?
Authorization is a critical aspect of any application. Understanding different authorization strategies can significantly improve the security and flexibility of your projects. This tutorial provides practical examples and clear explanations to help you implement these concepts in your own NestJS applications.
