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

There's another BackboneMixin, courtesy of Eldar Djafarov, that re-renders your component when the model changes and also provides a very convenient way to get two-way databinding:

  var BackboneMixin = {
    /* Forces an update when the underlying Backbone model instance has
     * changed. Users will have to implement getBackboneModels().
     * Also requires that React is loaded with addons.
     */
    __syncedModels: [],
    componentDidMount: function() {
      // Whenever there may be a change in the Backbone data, trigger a reconcile.
      this.getBackboneModels().forEach(this.injectModel, this);
    },
    componentWillUnmount: function() {
      // Ensure that we clean up any dangling references when the component is
      // destroyed.
      this.__syncedModels.forEach(function(model) {
        model.off(null, model.__updater, this);
      }, this);
    },
    injectModel: function(model){
      if(!~this.__syncedModels.indexOf(model)){
        var updater = this.forceUpdate.bind(this, null);
        model.__updater = updater;
        model.on('add change remove', updater, this);
      }
    },
    bindTo: function(model, key){
      /* Allows for two-way databinding for Backbone models.
       * Use by passing it as a 'valueLink' property, e.g.:
       *   valueLink={this.bindTo(model, attribute)} */
      return {
        value: model.get(key),
        requestChange: function(value){
            model.set(key, value);
        }.bind(this)
      };
    }
  }
