Relationship-based access control in Node.js can be implemented using a Zanzibar-inspired model with type-safe schema definitions. You define subjects, objects, and relations, then use an AuthSystem to map actions to relations and enforce permission checks.

RBAC manages permissions through static role assignments, whereas ReBAC evaluates permissions dynamically based on relationships between entities. In TypeScript, both models can be unified using a Zanzibar-style schema that supports group hierarchies and relationship graphs.

You model RBAC and ReBAC permissions in TypeScript by defining type-safe schemas for subjects, objects, relations, and actions. The schema maps actions to specific relations, allowing the AuthSystem to evaluate complex hierarchical permissions accurately.

Yes, Prisma can be used as a storage adapter for authorization checks. The system supports pluggable storage adapters, including Prisma for persistent relational data and an in-memory adapter for testing and local development.

A Zanzibar-inspired authorization model handles complex workflows by evaluating relationship tuples rather than static roles. It supports group-based permissions and hierarchical data structures, enabling granular access control across interconnected objects and subjects.

Using an embeddable access control library means authorization logic runs directly within your application process. This simplifies deployment but requires you to manage storage adapter configurations and schema migrations manually as your permission structures scale.
