This is a question a friend of mine asked me.
I was sure he was kidding. I said: “sure! Use google drive, or S3 or any large file storage provider and give her the link”.
Then he came with some requirements that made the initial ask somewhat more complicated.
- Should not cost money, not for my friend and not for his grandma
- Should not be uploaded to the cloud
- Grandma won’t need to install anything, preferably use a browser only
I was somewhat puzzled. If he doesn’t want it to cost money, this means his own server is off the table. So nextcloud is not an option.
Not uploading the files means services that host your files are off the table too. So no google drive, no S3, no mediafire, no we transfer, not even github. This meant she had to get the files directly off my friends computer. The only reliable way I knew to do that without installing anything are services like sharedrop, but they only work on the local network. It can be done with other protocols, like ftp, bittorrent and others, but that would violate the third requirement. At this point, I was about to tell him it is not doable. However, after giving a bit more thought, I came to a solution.
I figured torrent is the best option, but wasn’t sure how to get that into the browser. Since requirement number 3 prevents the installation of additional software, and I am sure my friend would not enjoy teaching his grandma to use torrents, that would be long, tedious and will likely fail, it had to be in the browser.
I remembered the webtorrent project. This would solve my issue of bringing torrents to the web, but didn’t solve the issue of not uploading the file somewhere. It basically meant my friend needed a way to create the torrent and then share the torrent file on a web page.
I have a laptop running webtorrent at home, which basically seeds the files on the page above in the webtorrent protocol, which is just a regular torrent protocol with the transport part using webrtc instead of tcp or udp. A side benefit of this is the fact ISP’s don’t throttle this kind of traffic, as it looks like webrtc communication, and not torrent communication.
I told my friend to use webtorrent desktop so he won’t need to run node and npm for the CLI version I used. It is a simpler way to create the torrent from the file and magnetize it.
After my friend did that, he was very happy with the outcome, but came with another ask, can the files be private? I didn’t think about a good solution to this one yet, but I think if he would agree to self host and pay a few dollars a month I would recommend setting up a private peertube instance.
