## What it is
A Node.js library implementing hierarchical role-based access control (RBAC) with roles, permissions, and grant inheritance. It supports in-memory storage by default and custom storage backends via an extensible Storage class.

## Use cases
- implement role-based access control in a nodejs app
- check if a user role can perform an action
- define hierarchical roles with inherited permissions
- manage user permissions and roles in an api
- add authorization middleware to express routes
- store rbac roles and grants in a custom database

## When to choose
- you need hierarchical role inheritance in a Node.js application
- you want a lightweight, dependency-free RBAC library with pluggable storage
- you need simple permission checks like can(role, action, resource)

## When to avoid
- you need attribute-based or policy-based access control (ABAC/ReBAC)
- you are not using Node.js or JavaScript
- you need built-in database adapters rather than writing your own storage layer

## Facets
