Feature request: directory and file stat #31

Closed josephmturner closed 1 year ago

josephmturner commented 1 year ago

Is it possible to get information about a Hyperdrive path (to a file or a directory) without downloading its contents? I am interested in ctime, mtime, x-blocks, x-blocks-downloaded. This information could be quickly loaded to give the user a more complete view of a directory beyond just the names of its contents.

I this idea makes sense, maybe an interface could look like fetch('hyper://NAME/example/?stat', {method: 'GET'})

It should be possible to do a HEAD request and get all the metadata about a path without actually downloading it.

Is there data that's missing from there?

josephmturner commented 1 year ago

Great! Would you like me to add a section to the README describing that functionality?

RangerMauve commented 1 year ago

Will do!

josephmturner commented 1 year ago

Thank you!

You can get the version for a drive or file in the ETag header. Some files (not all) will also have a Last-Modified header based on the mtime of the file.

Unless there are other fields that are needed this might be enough?

It looks like one way to set metadata.mtime when updating a file with a PUT request to hypercore-fetch is to use a FormData body. Is it possible to set metadata.mtime when updating a file with a PUT request without using a FormData body?

It should be getting set in both situations. If it isn't it's a bug. I'll fix it.

Fixed! Gonna push to hyper-gateway soon
