(JavaScript) Synchronize Remote Directory Tree

Uploads a directory tree from the local filesystem to the FTP server. Synchronization modes include:

mode=0: Upload all files
mode=1: Upload all files that do not exist on the FTP server.
mode=2: Upload newer or non-existant files.
mode=3: Upload only newer files. If a file does not already exist on the FTP server, it is not uploaded.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

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

var ftp = new CkFtp2();

ftp.Hostname = "ftp.example.com";
ftp.Username = "login";
ftp.Password = "password";

ftp.KeepSessionLog = true;

// Connect and login to the FTP server.
success = ftp.Connect();
if (success !== true) {
    console.log(ftp.LastErrorText);
    return;
}

// Set the current remote directory to the root of
// the tree where files are uploaded.
success = ftp.ChangeRemoteDir("/abc123");
if (success !== true) {
    console.log(ftp.LastErrorText);
    return;
}

// Recursively upload all non-existant and newer files.
var mode = 2;
success = ftp.SyncRemoteTree("c:/temp/abc123",mode);
if (success !== true) {
    console.log(ftp.LastErrorText);
    return;
}

success = ftp.Disconnect();

// Display the session log.  
console.log(ftp.SessionLog);
