Expecting a function in instanceof check, but got body - Trying to create view in Backbone

Question

I am trying to create a view in Backbone and trying to load libs via node require. i am able to output to console from Model/Collection but when i start to create view i am getting error "Expecting a function in instanceof check, but got body". I tried to load View via $(function()({}) and also tried $('document').ready but no luck - any suggestions as to what i am missing or doing wrong here. Thank you

    var express = require('express');
    var $ = require('jQuery');
    var _ = require('underscore');
    var Backbone = require('Backbone');
    var app = express();

    app.use(express.static(__dirname + '/'));
    app.listen(process.env.PORT || 3000);

    var myModel = Backbone.Model.extend();
    var myCollection = Backbone.Collection.extend({
        model: myModel,
        url: "myjson.json",
        parse: function(response) {
            return response.cars;
        }
    })

     var cars = new myCollection();

    var myView = Backbone.View.extend({

        el: 'body',

        initialize: function() {

            cars.fetch();
            this.render();
        },
        events: {
            'click div.test': 'render'
        },
        render: function() {

            cars.each(function(myModel) {
                var _comp = myModel.get('make');
                $('div.new_test').append(_comp);

                console.log(_comp);
                return this;
            })
        }
    })

     var yourView = new myView();

Answer 1

Maybe this might be a problem.

initialize: function() {
     cars.fetch();
     this.render();
},

You are fetching the collection ( Which is Asynchronous ) and immediately calling the render method.

Instead listen to the reset event on the collection and which will fire after the collection is populated

initialize: function() {
     this.listenTo(cars, 'reset', this.render);
     cars.fetch();
},

And move the return this to outside the $.each loop.

Add Backbone.$ = $; like so:

var express = require('express');
var $ = require('jQuery');
var _ = require('underscore');
var Backbone = require('Backbone');
Backbone.$ = $;
