What is OS Module ?

 

In Node.js, the 'os' (operating system) module provides a set of methods to interact with the operating system. It allows you to access information about the system's resources, network interfaces, and other related details. Here are some commonly used functionalities provided by the OS module.

 

 

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

 

Returns a string identifying the operating system CPU architecture (e.g., 'x64').

 

 

 

const os = require("os");
console.log(os.freemem()/(1024*1024));
console.log(os.freemem()/(1024*1024*1024));

 

Returns the amount of free system memory in bytes. 

 

 

 

 

const os = require("os");

console.log(os.totalmem()/(1024*1024));
console.log(os.totalmem()/(1024*1024*1024));

 

Returns the total amount of system memory in bytes.

 

 

 

 

const os = require("os");

console.log(os.hostname());

 

Returns the host name of the operating system.

 

 

 

const os = require("os");

console.log(os.platform());

 

 

Returns a string identifying the operating system platform (e.g., 'darwin', 'win32', 'linux').
