Node js os.machine() Method

The os.machine method is an inbuilt application programming interface of the os module which is used to get the machine type. The os package contains the required function to perform operating system operations.

Syntax:

os.machine()

Parameters: This function does not have any parameters.

Return Value: This function returns the machine type in the string type. Returns the machine type as a string, such as arm, arm64, aarch64, mips, mips64, ppc64, ppc64le, s390, s390x, i386, i686, x86_64.

Example 1: The below example illustrates the os.machine() method in Node js.

Note: The output may be different according to your computer operating system.

// Node.js program to demonstrate the
// os.machine() method

// Require os module
const os = require('os');
console.log(os.machine());

Output:

x86_64

Example 2: The below example illustrates the os.machine() method in Node js

// Node.js program to demonstrate the
// os.machine() method

// Require os module
const os = require('os');

// Printing os.platform() value
const platform = os.machine();

switch (platform) {
    case 'arm': console.log("arm machine type");
        break;
    case 'arm64': console.log("ARM CPU architecture");
        break;
    case 'x86_64': console.log("64-bit processing");
        break;
    default: console.log("unknown platform");
}

Output:

64-bit processing

Note: The above program will compile and run by using the node index.js command.
