What is os?

The 'os' npm package provides a set of operating system-related utility methods and properties. It allows you to interact with the operating system in a variety of ways, such as retrieving information about the system's architecture, CPUs, memory, and network interfaces.

What are os's main functionalities?

System Architecture

This feature allows you to get the operating system CPU architecture. The code sample prints the architecture of the CPU, such as 'x64' or 'arm'.

const os = require('os');
console.log(os.arch());

CPU Information

This feature provides information about each logical CPU core. The code sample prints an array of objects containing details about each CPU core, such as model, speed, and times.

const os = require('os');
console.log(os.cpus());

Free Memory

This feature allows you to get the amount of free system memory in bytes. The code sample prints the amount of free memory available on the system.

const os = require('os');
console.log(os.freemem());

Network Interfaces

This feature provides information about the network interfaces. The code sample prints an object containing details about each network interface, such as IP addresses and MAC addresses.

const os = require('os');
console.log(os.networkInterfaces());

Uptime

This feature allows you to get the system uptime in seconds. The code sample prints the number of seconds the system has been running.

const os = require('os');
console.log(os.uptime());

systeminformation

The 'systeminformation' package provides detailed system and hardware information and statistics. It offers more comprehensive data compared to 'os', including information about the battery, graphics, and processes. It is more feature-rich and suitable for applications requiring extensive system details.

node-os-utils

The 'node-os-utils' package offers a set of utilities to get system information and perform system operations. It provides functionalities similar to 'os', such as CPU, memory, and disk usage statistics, but also includes additional features like process management and network speed tests.

si

The 'si' package is a lightweight alternative to 'systeminformation' and provides essential system information. It is less comprehensive than 'systeminformation' but offers a simpler API for retrieving basic system details like CPU, memory, and disk usage.
