## What it is
A minimalistic access control list (ACL) library for Node.js applications, inspired by Zend_ACL. It manages users, roles, hierarchies, and resource permissions, with built-in Redis, MongoDB, and in-memory backends plus Express middleware.

## Use cases
- add role-based access control to a node app
- protect express routes with permissions middleware
- manage user roles and permissions in redis or mongodb
- restrict users from accessing other users' content
- implement hierarchical roles for an api

## When to choose
- you need flexible role/permission-based authorization in a Node.js app
- you use Express and want middleware to guard resources
- you want pluggable backends like Redis or MongoDB for storing ACLs

## When to avoid
- you need actively maintained software with ongoing commits
- you want a full-featured authorization framework like OPA or Casbin
- your project is not JavaScript/Node.js

## Facets
- artifact type: library
- maturity: maintenance
- function: authorization, middleware, auth
- domain: security, web-development, backend
- platform: -
- tags: acl, role-based-access-control, express-middleware, redis-backend, mongodb-backend, nodejs
