节点. js 作业系统
操作系统是用于提供计算机操作系统信息的节点模块。 优势: 提供与操作系统交互的功能。它提供操作系统的主机名，并以字节为单位返回可用的系统内存量。 例 1:
java 描述语言
// Include os module and create its object
var os = require('os');
// return the cpu architecture
console.log("CPU architecture: " + os.arch());
// It returns the amount of free system memory in bytes
console.log("Free memory: " + os.freemem());
// It return total amount of system memory in bytes
console.log("Total memory: " + os.totalmem());
// It returns the list of network interfaces
console.log('List of network Interfaces: ' + os.networkInterfaces());
// It returns the operating systems default directory for temp files.
console.log('OS default directory for temp files : ' + os.tmpdir ());
输出:
例 2:
java 描述语言
// Include os module and create its object
var os = require('os');
// return the endianness of system
console.log("Endianness of system: " + os.endianness());
// It returns hostname of system
console.log("Hostname: " + os.hostname());
// It return operating system name
console.log("Operating system name: " + os.type());
// It returns the platform of os
console.log('operating system platform: ' + os.platform());
// It returns the operating systems release.
console.log('OS release : ' + os.release());
输出:
