Is there a plugin that can track data change and sync to client?

[jackiesun8]

I use mongoose in a game server development. Mongoose has ability to track data change and sync to database.Now I want to sync data to client at data change.But this sync mechanism can't use mongoose's build-in.Because the sync opportunity is various(database'data is cached in memory and sync to database at player offline)

Not that I know of. Node's Object.observe() function may be helpful, but I'm not sure how well that'll work with mongoose documents. I would try: Object.observe(doc._doc, function() {});

@vkarpov15 mongoose's mechanism about tracking data change is?

[vkarpov15]

Not very extensible I'm afraid. At a high level, mongoose uses Object.defineProperty() to define custom getters/setters for every field you define in your schema and uses those to track changes on documents.
