Examples
Here are some examples of the functionality in this library
CPU information
const si = require('systeminformation')
si.cpu(function (data) {
console.log('CPU Information:');
console.log('- manufucturer: ' + data.manufacturer);
console.log('- brand: ' + data.brand);
console.log('- speed: ' + data.speed);
console.log('- cores: ' + data.cores);
console.log('- physical cores: ' + data.physicalCores);
console.log('...');
})
You will see something like this
C:\Program Files\nodejs\node.exe .\test.js CPU Information: - manufucturer: AMD - brand: Ryzen 5 3600 6-Core Processor - speed: 3.6 - cores: 12 - physical cores: 6
Memory information
const si = require('systeminformation');
si.mem(function (data) {
console.log('memory information:');
console.log('- total: ' + data.total / 1024 / 1024 + ' Gb');
console.log('- free: ' + data.free / 1024 / 1024 + ' Gb');
console.log('- used: ' + data.used / 1024 / 1024 + ' Gb');
console.log('...');
})
You will see something like this
memory information: - used: 20863.59375 Gb - free: 11855.3203125 Gb - total: 32718.9296875 Gb
Operating system information
const si = require('systeminformation');
si.osInfo(function (data) {
console.log('OS information:');
console.log('- platform: ' + data.platform);
console.log('- distro: ' + data.distro);
console.log('- release: ' + data.release);
console.log('- build: ' + data.build);
console.log('- servicepack: ' + data.servicepack);
console.log('...');
})
You will see something like this
OS information: - platform: win32 - distro: Microsoft Windows 10 Pro - release: 10.0.19042 - build: 19042 - servicepack: 0.0
