File storage tree

[jonocodes]

This may be more of a question.

Since file are stored in a flat list, is there away to access them more like a hierarchical file system? If not, I could build a tree myself, but want to make sure this is not a bad idea. I guess I would have to listen for add/remove events, etc.

Here is an example use. Sometimes I want to look up the size of a directory. For example I may want to look up:
/foo/bar/baz
or
/kind/of/deep/structure/directory1

What I do now is a full scan of the entire remoteStore for any file path starting with '/foo/bar/baz/'. Then I fetch their file sizes and add them up.
This full scan can be expensive if there are thousands of files.

The response to a GET request to /kind/of/deep/structure/directory1 contains a list of the documents.

Ok, I see that when it connects, a bunch of requests are made to find the content of each folder. Not sure how this works on other providers like Dropbox.

I dont know much about the internals of this js lib, but is this something I would access outside of the lib api?
Are you recommending I re-initiate those GETs or intercept the ones already going out?
My preference was to do this through the remoteStorage.js objects since its the most knowledgeable of what is in sync and what is not.

If you are using the remotestorage.js library, use this call:

If you use caching, then you won't get the metadata at the moment. This is a missing feature, which wasn't implemented when more metadata was added to the listings in the protocol specification: #1108

It's now almost on the top of my personal list for getting around to, now that #1331 is merged. (Or if someone else wants to take a stab at it, just comment in that issue, of course!)

Edit: Note that this will only give you the sizes for documents at that folder level. So you would at least have to traverse the tree and sum up the folder sizes in your case.
