I looked into
node.js and its installation is quite simple. After you install the main binary package, the "node" command becomes available in the shell. So you can create a javascript file and do:
> node app.js
And the app runs.
Now if you want to install a module, you can navigate to your project's folder and do:
> npm install express
And the "express" module is installed in that folder.
I think this is very simple and elegant. There is no fancy configuration or environment settings. It is dead simple.
Keep this in mind when you work on luan's installation.
