handling backbone model/collection changes in react.js

Question

I\'ve been working with facebooks framework React.js together with Backbone for the last couple of weeks and I\'m still not entirely sure what is the most appropriate way to

Answer 1

I had been playing around with the BackboneMixin mentioned here and a couple other react resources (of the limited info currently out there). I found that when I was listening to a collection that was being updated from the server, just as many n 'add' events are going to be triggered on the collection and listened to by the BackboneMixin, thus calling force update n number of times, which calls render and whatever is called from render n number of times.

Instead, I used underscore/lo-dash's throttle method to limit the number of times forceUpdate would be called. At the very least this has limited the render method from being called so much. I know react isn't actually doing any DOM manipulation there, and its just a virtual DOM, but still there is no reason it should be called 100 times for 100 immediate additions to a Collection.

So my solution looks like https://gist.github.com/ssorallen/7883081 but with the componentDidMount method like this instead:

componentDidMount: function() {
  //forceUpdate will be called at most once every second
  this._boundForceUpdate = _.throttle(this.forceUpdate.bind(this, null), 1000);
  this.getBackboneObject().on("all", this._boundForceUpdate, this);
}
