How to get the operating system's current user group id using Node.js?

Published April 5, 2021

To get the OS current user group id or (gid) in Node.js, you can use the userInfo() method from the os module and then use the gid property from the object returned.

// require os module
const os = require("os");

// invoke userInfo() method
const userInfo = os.userInfo();

// get gid property
// from the userInfo object
const gid = userInfo.gid;

console.log(gid); // 20

See the above code live in repl.it.

That's all! 😃
