Can I save data on my computer from a hosting site?

Question

JavaScript

So, in the process of learning Node.js, I got to the point where I needed to learn how to upload a project to the network. I'm new to programming and don't really know what to do.
There is wordpress in php, I tried to find something similar for Node, I came across formage and allcountjs . Is it possible to make an admin panel for the site from this?
In search of a hosting, I learned to throw on Heroku and found Cloud9 yesterday. I would like the project to turn out to be free, at least not for a long time - for me to study. And Heroku, as I looked, limits the space on the hard disk + only 1000 hours for free. 450 mb mongodb or 5 mb MySQL is a bit too much for me. Is it possible to somehow save data on my computer, but the site would be hosted, or are there special services for this? Correct me if I said something wrong.
Oh, and is Node.js suitable for a site where you need to accept user files (mp3), it seems to work locally, and pull out the metadata, and write the path to the saved file on disk to the database. (Glad any useful literature).
In the right direction, am I moving? Thanks in advance

Answer 1

You can make a server out of your computer. But in order to access the site, you have to keep your computer on.
