How to check if NodeJS is run by root

Use this function to determine if the current NodeJS process is being run by the root user:

is_current_user_root.js

function isCurrentUserRoot() {
    return process.getuid() == 0; // UID 0 is always root
}

function isCurrentUserRoot() {
    return process.getuid() == 0; // UID 0 is always root
}

Usage example:

is_current_user_root_usage.js

if(isCurrentUserRoot()) {
    // TODO Your code for root user goes here
} else {
    // TODO Your code for NON-root user goes here!
}

if(isCurrentUserRoot()) {
    // TODO Your code for root user goes here
} else {
    // TODO Your code for NON-root user goes here!
}

This works since the UID of the root user is always 0 on Linux/Unix systems.

Note: You don’t need to

process_require.js

const process = require("process");

const process = require("process");

since the process object is automatically imported in any NodeJS environment
