Use Example

To Download

var sftp        = new JJsftp("host", "user", "password"),
    localPath   = "String/Path/To/Place/The/Download"
    filelist    = [{
          remote    : "/Path/To/Remote/File.*"
        , local     : localPath+"file.*"
    },{
          remote    : "/Path/To/Another/Remote/File.*"
        , local     : localPath+"anotherFile.*"
    }];

    sftp.downloadList(filelist, function(data){
        /* Wow everything goes good, but just in case verify data.success */
    }, function(error){
        /* Wow something goes wrong, check the error.message */       
    });

To Upload is the same but calling upload or uploadList and by default will override a file if exists in server

Of course if you want, you could add any of the JJsftp events to document and listen the progress of the download by example

#### Know Issues

• upload does not work on iOS (Yet)
• cancel does not work on iOS (Yet), therefore SFTPActionCancell is never trigger.

There is a big TODO list, but in resume

• Bug Resolve =>
  • No Connection Break The App (Should The plugin warning the user or just don't do anything)
  • Only receive the absolute platfomr path (Without file://), should be replace in plugin don't force the user to replace it
  • Events just send a simple string object, need to be parse by user, should be the as many as need witouth the need to parse it
• Write a better documentation
• Propose new utils features (I think maybe in a fetch directory will be util) without lose the perspective of the plugin (Upload - Download via SFTP)
• Add iOS Support (Be Patient) (Partial done, download now available)
• Improve Uploading and Downloading feature
