RBAC in Laravel: A Practical Deep Dive

A comprehensive guide to implementing Role-Based Access Control (RBAC) in Laravel without external packages. Covers the theory behind RBAC (core, hierarchical, and constrained models), then builds a team-scoped implementation including: a Permission enum and RoleDefinition value objects, a database schema with a team_user_roles pivot table, effective permission resolution with caching, separation-of-duty constraints, role escalation prevention, integration with Laravel Gates and Policies, cache invalidation strategies, and Pest tests covering permission unions, constraint violations, and policy behavior. Also discusses common pitfalls like role explosion, business logic in controllers, and missing audit trails.
