🔧 Usage

Setting Up Roles and Permissions

Define roles and their permissions in the roles.json file or any database you prefer.

Example roles.json:

{
  "admin": ["create_user", "delete_user", "update_user"],
  "editor": ["update_content", "delete_content"],
  "viewer": ["read_content"]
}

Integrating RBAC in Your App

1. Import and initialize the RBAC system:

   const RBAC = require('./rbac');
   
   const roles = require('./roles.json'); // Load roles from JSON or database
   const rbac = new RBAC(roles);

2. Assign roles to users:

   const userRoles = {
       user1: ['admin'],
       user2: ['editor'],
   };

3. Perform access checks:

   const hasAccess = rbac.can('user1', 'delete_user');
   console.log(`Access granted: ${hasAccess}`);

🧑‍💻 Examples

Checking Permissions

rbac.can('user2', 'delete_user')
  .then((access) => {
    if (access) {
      console.log('Access granted!');
    } else {
      console.log('Access denied.');
    }
  })
  .catch(err => console.error(err));

Adding a New Role

You can dynamically add new roles and permissions using:

rbac.addRole('new_role', ['new_permission']);
