Simple-express-acl NPM

Simple Express ACL Middleware

Simple ACL middleware that works well with JWT and Passport's JWT strategy

Install

$ npm install --save simple-express-acl

Usage

Looks for an array of user role's in req.user.roles

If admin is found in req.user.roles, that is considered a Super Role that has access to all resources, regardless of rule definitions.

If middleware acl.check is defined on an Express route, and the user role is not defined in the role definitions, access will be denied by default.

Sample Express `router.js` file

import acl from 'simple-express-acl'

// Set custom YML file with rules
acl.setRules( __dirname + '/config/acl.yml' )

// Set rules from an object
acl.setRules( rulesObject )

// Set URL prefix (e.g. for API versioning in routes)
acl.setPrefix('/api/v1')

// Set super role (default: admin)
acl.superRole = 'root'

// Set unauthorized response status (default: 401)
acl.responseStatus = 404

// Set unauthorized response
acl.response = {
    status:  'error',
    message: 'You do not have access mister...'
}

/**
 *    Express Routes
 */

import { Router } from 'express'
const router = new Router()

router.use( '/user', acl.check, require('./controllers/user.js') )

Sample `acl.yml`:
