Do you have sample code for uploading and transforming images using Node.js?

You can find Node.js sample projects that demonstrate common Cloudinary use cases in this GitHub repository

Included are two sample projects:

Basic:

This sample project uploads local and remote images to Cloudinary and generates URLs for applying various image transformations on the uploaded files.

Photo Album:

A fully working web application that allows you to upload photos, maintain a database with references to them, list them with their metadata, and display them using various cloud-based transformations. Image uploading is performed both from the server side and directly from the browser using a jQuery plugin.
