Role-based access control (RBAC for short) is a common pattern for determining whether a user is authorized to perform a certain action. The idea is that each user has a set of roles, and each action the user can take has a set of roles that are allowed to perform the action. Sounds pretty simple, right? Well check out Val Karpov's "Why You Shouldn't Write Your Own RBAC in Node.js" for all the details.

Why You Shouldn't Write Your Own RBAC in Node.js
Implementing RBAC in Node.js can be a challenge, especially when it comes to navigating relationships between roles and permissions. As your authorization model grows, issues like scoped roles and distinct permissions become more prevalent.
That's why Valeri Karpov suggests using a policy language. In this post, Val shares how to write authorization code in Node.js and compares it to the model you can build using Oso, an authorization service that includes the open source policy language library, Polar.
