elevated

Check if a script is executed with elevated permissions:

• Using SUDO on Linux
• From an administrator account on Windows

A lightweight utility to verify and enforce elevated privileges for Node.js applications when you need to perform operations that require administrative rights.

Compatibility

Installation

# NPM
npm install elevated

# Yarn
yarn add elevated

# PNPM
pnpm add elevated

Usage examples

CommonJS (Node.js)

Functions

The check method returns a boolean indicating if we are elevated or not.

console.log(
  require('elevated').check() ? 'elevated' : 'unelevated'
);

Using required function, an exception is thrown with a platform specific message if the runtime is not elevated.

require('elevated').required();

Custom error message

Customize the error message thrown by required() when the script is not running with elevated permissions...

require('elevated').required('Please run as administrator');

...or by setting-up the default one.

require('elevated').defaultMessage = 'Please run as administrator';

ESM (ECMAScript Modules)

Using named imports

import { check, required } from 'elevated';

// Check if elevated
console.log(check() ? 'elevated' : 'unelevated');

// Require elevated permissions
try {
  required();
  console.log('Script is running with elevated permissions');
} catch (error) {
  console.error('Error:', error.message);
}

Using default import

import elevated from 'elevated';

console.log(elevated.check() ? 'elevated' : 'unelevated');

(...)

Testing
