It is very good idea, and a nice way how to integrate with existing libraries. It shields user from one round of conflict resolution handling. I have created a small diagram to better understand that and it revealed one more fact: https://docs.google.com/drawings/d/1vIqYjfukHwb9HVuYAlf9eO5U_Eopgl9EOZyG2... As seen on the diagram, user would still have to Merge on the programmatic layer, where we could offer a DiffMatchPatch alghoritm, and/or integration with selected existing libraries (e.g. AngularJS ResoureProvider or Restangular or similar Ember approach). I believe we don't have to handle "I work for second and later requests" problem you mentioned in the blog, since I assume ServiceWorker will react on the REST calls from the application once it is registered (not sure that's the case). That's with a question mark. :-) On Mon, Jan 5, 2015 at 6:15 PM, Daniel Bevenius <daniel.bevenius(a)gmail.com&gt; wrote:
