Hi, I was wondering whether you are planing to implement encode for fit files from the js object ? I Your parser is the best I could find (I tried a lot :)) but I would like to save the changes back to an actual fit file after editing.

thanks

Atm quite difficult but PR's are welcome.

That said for export to GPX you could check https://github.com/sports-alliance/sports-lib that leverages this lib :-D

@Abasz, you could handle writing back to the file via the File System Access API. this article gives a nice introduction: https://web.dev/file-system-access/

Thanks for the reply, the problem is not that I am not able to save a file on hard disk, but rather the encoding of a json to FIT format binary.

I have not tried this for a while, but if I remember correctly my issue was that if I decode the FIT file to JSON change something in the json there is no way to encode back to FIT binary.

I actually started using a python package for this purpose. It correctly decodes and then encodes it back.

ok. my misunderstanding. sorry about this.
note: I'm not involved with this project, just saw the issue and thought I could be of help. I was not :|
