machini

machini is a utility to get hardware information about system devices.

• Lightweight and Fast!
• It doesn't use any additional modules - it utilizes pure Node.js APIs.
• You don't need system privileges to get the value.
• Friendly to modern Node.js development and TypeScript.
• Cross-platform (Windows, macOS, Unix/Linux) support.

Installation

Note

machini is a module that runs on the Node.js runtime and is not available in a typical web environment (client). Since it utilizes the runtime of Node.js to get device information, it defeats the purpose of getting the end user's device information. To get the client's device ID, consider a solution like UUID (randomUUID in crypto).

machini requires Node.js 18.x or higher, and the repository is serviced through NPM.

machini is ESM-only. You must use import instead of require to load the module. There are workarounds available for CommonJS, but we recommend using ESM based on recent JavaScript trends.

After configuring the node environment, you can simply run the following command.

# via npm
$ npm install machini

# via yarn
$ yarn add machini

# via pnpm
$ pnpm install machini

import { machineId } from 'machini';

async function main() {
	console.log(await machineId());
}

Methods

machineId (Promise<string>)

Gets the unique UUID of the current device. Throws an error if the value is not retrieved. Returns a Promise object, so use await or .then() to wait for the operation to complete and get the correct value.

The UUID may change when the system is reinstalled or as the virtual machine's environment changes. On some systems, this value can also be modified by the system administrator (but this is rarely utilized as the system may become unstable after modification).

This method returns the same value for every user on the system.

console.log(await machineId()); // a642d9e1-6063-4da7-8ea8-2298f989d01d

sid (Promise<string>)

Gets the Security Identifier (SID) value for the current user on the device. Throws an error if the value is not obtained.

The SID value is only supported on Windows and macOS. Other OSes throw an error.

Also, the SID value used on macOS is a value created for the directory service. If you don't trust this value, use the machineId method instead.

This value can be changed by the user.

console.log(await sid()); // S-1-5-21-406418252-5582013529-1321253100-2001
