Node.js os.type() Method Last Updated : 12 Oct, 2021 Comments Improve Suggest changes Like Article Like Report The os.type() method is an inbuilt application programming interface of the os module which is used to get Operating system name. Syntax: os.type() Parameters: This method does not accept any parameters.Return Value: This method returns a string that represents operating system name. The returned value can be one of these 'Darwin' for MacOS, 'Linux' for Linux and 'Windows_NT' for windows.Below examples illustrate the use of os.type() method in Node.js: Example 1: javascript // Node.js program to demonstrate the // os.type() method // Allocating os module const os = require('os'); // Printing os.type() value console.log(os.type()); Output: Windows_NT Example 2: javascript // Node.js program to demonstrate the // os.type() method // Allocating os module const os = require('os'); // Printing os.type() value var type = os.type(); switch(type) { case 'Darwin': console.log("MacOS"); break; case 'Linux': console.log("Linux operating system"); break; case 'Windows_NT': console.log("windows operating system"); break; default: console.log("other operating system"); } Output: windows operating system Note: The above program will compile and run by using the node index.js command.
