SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires github.com/casbin/casbin/v2, github.com/casbin/gorm-adapter/v3, gorm.io/driver/postgres, and includes scripts (resource) and references (resource) and assets (resource) components.

What problem does it solve?

This Skill provides a comprehensive solution for implementing fine-grained authorization in Go applications, enabling robust role-based (RBAC) and attribute-based (ABAC) access control.

Core Features & Use Cases

  • Flexible Policy Models: Supports RBAC, ABAC, and hybrid models with domain support for multi-tenancy.
  • Database Integration: Seamlessly integrates with GORM adapters for persistent policy storage (PostgreSQL, MySQL).
  • Middleware Integration: Provides ready-to-use middleware for popular Go web frameworks like Chi and gRPC.
  • Use Case: Secure a multi-tenant SaaS application by defining distinct roles and permissions for users within each tenant, ensuring users can only access resources specific to their domain.

Quick Start

Use the implementing-casbin skill to set up RBAC authorization in a new Go project using PostgreSQL.

FAQPage Schema
How do I implement RBAC authorization in a Go service using Casbin?▼

You implement RBAC authorization in Go with Casbin by defining a model configuration file and using the library to enforce role-based access control policies, integrating directly into your service logic.

How does Casbin integrate with GORM for PostgreSQL policy persistence?▼

Casbin integrates with GORM for PostgreSQL policy persistence by using the gorm-adapter to automatically load and save authorization policies, ensuring your access control rules remain synchronized with your database.

Can I use Casbin middleware with the Chi router and gRPC?▼

Yes, you can use Casbin middleware with the Chi router and gRPC to secure API endpoints, intercepting requests to enforce attribute-based and role-based access control before they reach your handlers.

What is the best way to handle multi-tenant access control in Go?▼

The best way to handle multi-tenant access control in Go is using Casbin's domain support, which allows you to define distinct roles and permissions for users within each tenant domain for fine-grained security.

Does Casbin support ABAC models alongside RBAC in Go applications?▼

Yes, Casbin supports ABAC models alongside RBAC in Go applications, allowing you to implement hybrid policy models that evaluate user attributes and resource properties for fine-grained authorization.

What dependencies are required to set up Casbin with PostgreSQL?▼

Setting up Casbin with PostgreSQL requires the Casbin v2 library, the gorm-adapter v3 for database persistence, and the specific GORM PostgreSQL driver to establish the connection and store policies.
