Write FIT file/stream about sports-lib

[jimmykane]

Unfortunately its quite a task todo this. Currently I also dev the https://github.com/jimmykane/fit-parser which parses the FIT files. So far I have not seen any JS lib doing the encoding. I would love that but all people (including me) that have tried have "failed" due to the "complexity " I suppose.

I'd love to see this too :)

I'm interested too. Saw this https://developer.garmin.com/fit/file-types/activity/ . @jimmykane would you be willing to share your attempt at fit encoding?

Further reading and this is the protocol https://developer.garmin.com/fit/protocol/, more than a weekends work I think.

I tried using https://github.com/opal/opal to convert a ruby lib for encoding / decoding fit files to javascript, https://github.com/jpablobr/f4r/blob/main/lib/f4r.rb. But the outputted code was hard to read, and I configured it to ignore missing require statements, that is not convert all the required libs as well, so will not run. I wonder if porting this library by hand, or another to javascript would be the easist approach.
