The Node.js environment is fully managed and updated server-side. You just need to upload your project to the server and start it through our graphical interface (or the handy CLI tool).
The WebApps platform comes with the latest stable version of Node.js pre-installed and configured. You can use it for Node.js applications out of the box. However, it can also be used to run many other environments as well, for example Ruby on Rails, Django, etc.
