Sync directory structure with firebase ignoring the contents while preserving the heirarchy
I am trying to write a small electron application that syncs the directory structure of a certain folder with Firebase ignoring the actual contents. And struggling to design a strategy with low ovrhead when user renames, deletes or moves the children.
I am going with something like this for the schema
contenst = {
f1 : {
name : 'Folder 1',
type : 'dir',
parent : null
},
f2 : {
name : 'cat.jpg',
type : 'file',
parent : 'f1'
},
f3 : {
name : 'Subfolder a',
type : 'dir',
parent : 'f1'
},
f4 : {
name : 'dog.jpg',
type : 'file',
parent : 'f3'
}
}
This is the above directory structure in simple form.
+-- Folder1
|-- cat.jpg
+-- Subfoler_a
|--dog.jpg
Now on the app startup each time I have to re-sync the directory structure while keeping the bandwidth usage as low as possible.
Of course I could just read the whole directory and overwrite the server one with it but that will be quite expensive if there are thousands of files.
I cant use any file watcher because that wont work if the app is closed.
One solution is to download the server stored snapshot and calculate a diff with the local structure. That again means downloading the whole tree.
Is there any better solution to this.
As evident from the question title I only need to sync the structure. File contents don't matter.
