The Systeminformation Project

This is amazing. Started as a small project just for myself, it now has > 15,000 lines of code, > 600 versions published, up to 8 mio downloads per month, > 300 mio downloads overall. #1 NPM ranking for backend packages. Thank you to all who contributed to this project!

Please support this project ... ☕️

Over the past few years I spent more than 2.000 hours working on this project and invested in hardware to be able to test on different platforms. Currently I am working very hard on the next new version 6.0 completely rewritten in TypeScript and with a lot of new features. Any support is highly appreciated - Buy me a coffee.

Your contribution make it possible for me to keep working on this project, add new features and support more platforms. Thank you in advance!

New Version 5.0

The new Version 5 is here - this next major version release 5.0 comes with new functionality and several improvements and changes (some of them are breaking changes!):

added audio: get detailed audio device information
added bluetooth: get detailed bluetooth device information
added dockerImages, dockerVolumes: get detailed information about docker images and volumes
added printer: get information from detected printers
added usb: get detailed usb controller and device information
added wifi interfaces and connections: extended wifi information
better uuid function to get unique hardware and OS UUIDs
better/extended cpu info detection
better/extended system info detection
Apple Silicon M1/M2/M3 support
better Raspberry-PI detection
systeminformation website updated and extended with full documentation and examples [systeminformation.io][systeminformation-url]
lot of minor improvements

Breaking Changes in version 5: you will see several breaking changes for the sake of a more consistent API interface and to be future proof. Read the [detailed version 5 changes][changes5-url].

I did a lot of testing on different platforms and machines but of course there might be some issues that I am not aware of. I would be happy if you inform me when you discover any issues. Issues can be [opened here][new-issue].

Quick Start

Lightweight collection of 50+ functions to retrieve detailed hardware, system and OS information.

simple to use
get detailed information about system, cpu, baseboard, battery, memory, disks/filesystem, network, docker, software, services and processes
supports Linux, macOS, partial Windows, FreeBSD, OpenBSD, NetBSD, SunOS and Android support
no npm dependencies

Attention: this is a node.js library. It is supposed to be used as a backend/server-side library and will definitely not work within a browser.

Installation

npm install systeminformation --save

or simpler

npm i systeminformation

Give it a try with `npx`?

You just want to give it a try - right from your command line without installing it? Here is how you can call it with npx:

# get basic system info (System, OS, CPU)
npx systeminformation info

# obtain all static data - may take up to 30 seconds
npx systeminformation

Still need Version 4?

If you need version 4 (for compatibility reasons), you can install version 4 (latest release) like this

npm install systeminformation@4 —save

or simpler

npm install systeminformation@4

Usage

All functions (except version and time) are implemented as asynchronous functions. Here a small example how to use them:

const si = require('systeminformation');

// promises style - new since version 3
si.cpu()
  .then(data => console.log(data))
  .catch(error => console.error(error));

Core concept

[Node.js][nodejs-url] comes with some basic OS information, but I always wanted a little more. So I came up to write this little library. This library is still a work in progress. It is supposed to be used as a backend/server-side library (it will definitely not work within a browser). It requires node.js version 4.0 and above.

I was able to test it on several Debian, Raspbian, Ubuntu distributions as well as macOS (Mavericks, Yosemite, El Captain, Sierra, High Sierra, Mojave, Catalina, Big Sur) and some Windows 7, Windows 8, Windows 10, FreeBSD, OpenBSD, NetBSD and SunOS machines. Not all functions are supported on all operating systems. Have a look at the function reference in the docs to get further details.

If you have comments, suggestions & reports, please feel free to contact me!

I also created a nice little command line tool called [mmon][mmon-github-url] (micro-monitor) for Linux and macOS, also available via [github][mmon-github-url] and [npm][mmon-npm-url]
