(Node.js) Create Email Folder (sub-Mailbox)

How to create a new email folder (sub-mailbox). (In GMail, folders are called "labels". This example would create a new "label" in GMail.)

Install Chilkat for Node.js and Electron using npm at Chilkat npm packages for Node.js Chilkat npm packages for Electron on Windows, Linux, MacOSX, and ARM

var os = require('os');
if (os.platform() == 'win32') {  
    if (os.arch() == 'ia32') {
        var chilkat = require('@chilkat/ck-node21-win-ia32');
    } else {
        var chilkat = require('@chilkat/ck-node21-win64'); 
    }
} else if (os.platform() == 'linux') {
    if (os.arch() == 'arm') {
        var chilkat = require('@chilkat/ck-node21-arm');
    } else if (os.arch() == 'x86') {
        var chilkat = require('@chilkat/ck-node21-linux32');
    } else {
        var chilkat = require('@chilkat/ck-node21-linux64');
    }
} else if (os.platform() == 'darwin') {
    if (os.arch() == 'arm64') {
        var chilkat = require('@chilkat/ck-node21-mac-m1');
    } else {
        var chilkat = require('@chilkat/ck-node21-macosx');
    }
}

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    var imap = new chilkat.Imap();

    imap.Ssl = true;
    imap.Port = 993;

    // Connect to an IMAP server.
    var success = imap.Connect("imap.gmail.com");
    if (success !== true) {
        console.log(imap.LastErrorText);
        return;
    }

    // Login
    success = imap.Login("myLogin","myPassword");
    if (success !== true) {
        console.log(imap.LastErrorText);
        return;
    }

    // Create the new email folder (sub-mailbox) on the IMAP server.
    // If no folder path is provided, the new folder is a sub-mailbox of Inbox.
    success = imap.CreateMailbox("newFolder");
    if (success !== true) {
        console.log(imap.LastErrorText);
        return;
    }

    // (In GMail, folders are called "labels".  
    // This example would create a new "label" in GMail.)

    // Now create a sub-folder under "newFolder".
    // Make sure to use the proper separator char for your IMAP server.
    // The separator char used here is "/".   It is typically "/" or ".".
    // The SeparatorChar property contains the separator char
    // that should be used for the current IMAP session.
    success = imap.CreateMailbox("newFolder/subFolder_A");
    if (success !== true) {
        console.log(imap.LastErrorText);
        return;
    }

    console.log("Success.");
