How can you upload directory using node.js?

I'm new to node and want to upload directory using node.js can anybody please help?? Thank You If it's possible how?? and if not then why??

you can upload only files.
however there are workarounds,you can

  1. covert the folder to a zip file (client side), it really depends here on your case.
  2. upload the zip file
  3. then unzip it in the server

you can use google to find out how to do every step of those.

You can use use any Folder uploading library like https://github.com/blueimp/jQuery-File-Upload or https://dropzonejs.com which allows you to Drag and Drop whole directory using HTML5 features.
