Please read the part "Indeed. But I have an idea which I would like to
check if you agree" in my second message. That was the only way I found to
make it to work for any data type.

NodeJS has streams. They support writing strings/buffer/uint8array and

I totally agree. But we should provide at least a way using
local/sessionstorage with the possibility to download it to a file (as
showed in my previous example).

I'm not sure if the JS unit already maps the browser storage interfaces,
but we can write it (if you agree the ideia I showed in the second message).

I started the nodejs external classes in unit nodejsfs. Feel free to

Awesome. I'll check this as soon as we find a solution for the browser side
(it think we are almost there ...).
