## What it is
A NestJS module providing role- and attribute-based access control (RBAC/ABAC), built on top of onury's accesscontrol library. It offers decorator-based route guards, a RolesBuilder for defining grants, role inheritance, and attribute filtering.

## Use cases
- add role-based permissions to a NestJS API
- restrict route access with decorators and guards
- filter response data by allowed attributes per role
- define hierarchical roles with inherited permissions
- control access to own vs any resources
- load permission grants from a database

## When to choose
- you use NestJS and need fine-grained role/attribute authorization
- you want decorator-based guards with an ACGuard out of the box
- you need role inheritance and attribute-level filtering in-memory

## When to avoid
- you're not using the NestJS framework
- you need policy-as-code or external authorization services like OPA
- you need permissions persisted and evaluated at database level

## Facets
- artifact type: library
- maturity: active
- function: authorization, middleware
- domain: backend, web-development, security, developer-tools
- platform: -
- tags: nestjs, rbac, access-control, decorators, guards, permissions, nodejs, typescript
