Currently there's no way to utilize the IPFS filestore functionality.
I've seen a few other issues related to this:
ipfs-inactive/js-ipfs-http-client#843
ipfs-inactive/js-ipfs-http-client#564
They all still seem to be "WIP"
I'd really love to have this functionality available if possible. Is there anything that's preventing either of the approaches seen in those two issues from being implemented?
I can look into attempting a PR myself, I just don't want to be reinventing the wheel if the other two approaches would work.
