Interesting. Can you give us some insights into the actual porting? What features of Go were particularly helpful and what Node.js features did you miss the most?
The porting was pretty straightforward, the actual heavy lifting was provided by the https://github.com/anacrolix/torrent library.
One insight that I got from it is that the io.Reader and io.Writer interfaces can work very similar to node streams.
If you work with binary data at any point, it makes a lot of sense to provide those interfaces as there is a tremendous amount of code that can make use of it.
