Overview

Implement comprehensive Role-Based Access Control systems with permissions management, attribute-based policies, and least privilege principles.

When to Use

• Multi-tenant applications
• Enterprise access management
• API authorization
• Admin dashboards
• Data access controls
• Compliance requirements

Quick Start

Minimal working example:

// rbac-system.js
class Permission {
  constructor(resource, action) {
    this.resource = resource;
    this.action = action;
  }

  toString() {
    return `${this.resource}:${this.action}`;
  }
}

class Role {
  constructor(name, description) {
    this.name = name;
    this.description = description;
    this.permissions = new Set();
    this.inherits = new Set();
  }

  addPermission(permission) {
    this.permissions.add(permission.toString());
  }

  removePermission(permission) {
// ... (see reference guides for full implementation)

Best Practices

✅ DO

• Implement least privilege
