well, i've hacked something together for js here in this branch:  https://github.com/lholmquist/aerogear-js/tree/AGJS-124

it is in no way complete, just some idea's.

to run the tests here, you need to have dan's server running.

i'm currently trying out https://github.com/benjamine/JsonDiffPatch to do the diff/patching during an update conflict, 

Here is a quick and dirty API that i was thinking could be a start,  for JS at least

// Create a New Data Sync Object
 
var dataSync = AeroGear.DataSync( { syncServerUrl: "http://localhost:8080" } );
 
/* possibly more options here, like "auto-merge"
options = {
syncServerUrl: "link_to_sync_server",
autoMerge: false, //optional, defaults to false? Not sure this is the right spot for this, maybe should be in the update call
otheroptions: ....
}
*/
 
// Probably have 3 Methods: read, save( Update ), remove
// each one has 2 parameters, the "document" and the settings
 
/*
The document here is an object defined like in qmx's sync thought dump
var document = {
id: "123sjf2-i",
content: {
// Some Arbitrary JSON or an array or something serializable into JSON
},
rev: "SOME_REVISION_ID" // or rev_id or revision or revision_id, we can argue over names later
}
*/
 
dataSync.read( document, settings );
 
/*
--READ--
var settings = {
success: function( document ){}, // GET the document
error: function( error ){} // an error happened GETting the document, like it can't be found or something
}
*/
 
dataSync.save( document, settings );
 
/*
--Save--
document can be either an array or an object
if whatever is passed is in the form of the document specifed above, then save works as an "update"
var settings: {
autoMerge: // not sure if this should be here or in the constructor
success: function( document ){} // successful PUT to create the document or update the document,
conflict: function( error, current_model_from_server, delta_of_current_server_model_and_local_document ) // this delta thing should be nice and user friendly or something
SOME_OTHER_SPECIFIC_CALLBACK: function(){}, // Maybe other callbacks for specific events
error: function( error ){} // an error happened, catch-all ?
}
*/
 
dataSync.remove( document, settings );
 
/*
TBD
*/

Hi,

based on the ag.org "sync-branch" (see [1]), I created a SIMPLE first iOS hack of a "document" API with a HTTP client that talks to Dan's Server.  

The model ([2]) is quite easy/simple and the HTTP client supports CREATE/READ/REMOVE ([3]), based on the protocol defined on the README of the server.

The usage is covered in a test (like [4]).

Next: I guess next (if we continue using Dan's Server) is to see how this project can we weaved into the exisiting stores - but first I really wanted to get some client (like Luke's JS client) which executes against our current server draft/implementation.

BTW. the lib is based on AFN2.x (not sure we should use AFN 2.x at THIS point - switching to 1.x should not be that hard)
