In this short video, we’re building on our JWT plugin from the last session to add Role-Based Access Control (RBAC) to our Node.js application. We’ll walk through the process of extending our JWT authentication to allow fine-grained access based on user roles, using Fastify in a CommonJS setup. You’ll learn how to secure routes based on user roles, ensuring only authorized users have access to critical endpoints. Whether you’re building a simple API or a complex application, adding RBAC will elevate your security. Watch now to strengthen your authentication strategy with RBAC!
