Can anyone point me to a jsDAV example/manual on how to create a virtual file system. Because I can't find documentation about it, except this: http://code.google.com/p/sabredav/wiki/VirtualFilesystems
But that's not in nodeJS.

Thanks in advance
Devian

Hi Devian,

Sorry for replying late! For now only a short message: there's more information on the jsdav wiki on github.

I'll post a more elaborate message when I'm not on the road anymore after this weekend.

Cheers,

Mike.

Thank you Mike,
I went to the jsDAV wiki on gitHub but I found only one example (on the getting started page) on how to make a mirror of a folder structure on my own drive. But I need to make a virtual file system, so I had a look at the sabreDav wiki and tried to rewrite an existing (php) example to javascript. This resulted in the following code:
var jsDAV = require("jsDAV");
jsDAV.debugMode = true;
var File = require("jsDAV/lib/DAV/file");
var MyFile = File.extend({
    initialize: function(path) {
console.log("myFile > initialize");
        this.path = path;
    },

 getName: function() {
console.log("myFile > getName");
return "Hello World";
},

 "get": function() {
console.log("myFile > get");
return (new Buffer("Hello"));
},
 
getSize: function() {
console.log("myFile > getSize");
return 5;
},
getETag: function() {
console.log("myFile > getETag");
return null;
}
});
var Directory = require("jsDAV/lib/DAV/collection");
var myDirectory = Directory.extend({
    initialize: function(path) {
console.log("myDirectory > initialize");
        this.path = path;
    },

 getChildren: function() {
console.log("myDirectory > getChildren");
return (new Array());
},

 getChild: function(name) {
console.log("myDirectory > getChild");
return MyFile.new("Hello World");
},

 childExists: function(name) {
console.log("myDirectory > childExists");
return true;
},

 getName: function() {
console.log("myDirectory > getName");
return "Hello World";
}
});


var server = jsDAV.createServer({node: myDirectory.new("eenMap")}, 8000); 

OK I run this code in nodejs with no errors. Then I connect with Finder to "127.0.0.1:8000", this shows me a login window but when I select the guest option and click "connect", this window pops up and never closes 

Do you know what's the problem here or can you point me to a simple jsDAV example? Because I only find sabreDAV examples and don't know how to port these to javascript...

This is the log from nodejs:
