Store

// Creating a Data Store - Listening to textUpdate action

    init: function() {
        this.listenTo(textUpdate, this.output);
    },

        var i, args = Array.prototype.slice.call(arguments, 0);
        for (i = 0; i < args.length; i++) {
            this.writeOut(args[i]);
        }
    },
    writeOut: function(text) {
        this.trigger(text);
    }
});

Store - aggregate

// Creating an aggregate DataStore that is listening to textStore and statusStore
var storyStore = Reflux.createStore({
    init: function() {
        this.listenTo(statusStore, this.statusChanged);
        this.listenTo(textStore, this.textUpdated);
        this.storyArr = [];
    },
    statusChanged: function(flag) {
        if (flag === 'OFFLINE') {
            this.trigger('Once upon a time the user did the following: ' + this.storyArr.join(', '));
            // empty storyArr
            this.storyArr.splice(0, this.storyArr.length);
        }
    },
    textUpdated: function(text) {
        this.storyArr.push(text);
    }
});

Component

// Fairly simple view component that outputs to console
function ConsoleComponent() {
    textStore.listen(function(text) {
        console.log('text: ', text);
    });
    statusStore.listen(function(status) {
        console.log('status: ', status);
    });
    storyStore.listen(function(story) {
        console.log('story: ', story);
    });
}

new ConsoleComponent();

Invoke

// Invoking the action with arbitrary parameters
statusUpdate(true);
textUpdate("testing", 1337, { "test": 1337 });
statusUpdate(false);
/* Will output the following:

status: ONLINE
text: testing
text: 1337
text: { test: 1337 }
