I'm trying to get Masonry loaded into my app using RequireJS, but it keeps causing backbone to spit out a "object is not a function" error anytime I add it.
Edit: possibly related to this issue.
main.js
require.config({
paths: {
jquery: 'lib/jquery-1.9.1',
underscore: 'lib/underscore-1.5.2',
backbone: 'lib/backbone-1.0.0',
masonry: 'lib/masonry.pkgd'
},
shim: {
backbone: {
deps: ['underscore', 'jquery'],
exports: 'Backbone'
},
underscore: {
exports: '_'
}
}
});
require(['app'], function(App){
App.initialize();
});
app.js
define([
'jquery',
'underscore',
'backbone',
'masonry',
'collections/ideas',
], function($, _, Backbone, Masonry, IdeasCollection) {
var IdeasView = Backbone.View.extend({
el: $('#container'),
initialize: function() {
...
},
render: function(){
...
}
});
return IdeasView;
});
To use Masonry as a jQuery plugin with RequireJS, you’ll need to run jQuery bridget.
Check the documentation:
http://masonry.desandro.com/appendix.html#requirejs
You can download bridget here:
https://github.com/desandro/jquery-bridget
Then you can include an run bridget and it should work fine
define([
'jquery'
, 'underscore'
, 'backbone'
, 'config'
, 'app'
, 'jquery.masonry'
, 'jquery.bridget'
], function ($, _, Backbone, Config, App, Masonry, bridget) {
initialize : function () {
bridget('masonry', Masonry);
}
});
Hope it helps!
This is one way you can run it without bridget:
requirejs-config.js:
var config = {
paths: {
"lib-masonry": "Module/js/lib/masonry.pkgd.min"
},
shim: {
"lib-masonry": {
deps: ['jquery', 'jquery/ui']
}
}
}
and then in another module where you want to use it:
define([
'jquery',
'lib-masonry'
], function ($, Masonry) {
$.widget('ModuleNamespace.containerMasonry', {
options: {
},
_create: function() {
var msnry = new Masonry('.grid', {
itemSelector: '.grid__item',
columnWidth: 200
});
// .. code
}
});
return $.ModuleNamespace.containerMasonry;
});

I am trying to load JQuery datatables with Require.js
This is my JS module where I would like to use datatables :
define([
"jquery",
"text!orders_list.tpl",
"dataTables"
], function($, OrdersListTemplate, dataTables)
{
console.log($);
console.log($.fn.dataTable);
... more logic after
How I call my JS module in HTML :
require(['./js/config'], function (common)
{
require(
[
'js/modules/init',
...
'js/modules/orders_list.js'
],
function (init, ..., orders_list)
{
init.initialize();
...
orders_list.initialize();
});
});
How I have defined my config :
require.config({
shim: {
underscore: {
exports: '_'
},
backbone: {
deps: ['underscore', 'jquery'],
exports: 'Backbone'
},
...
},
paths: {
jquery: '../../shops_common/js/lib/jquery-1.9.1',
backbone: '../../shops_common/js/lib/backbone.min',
underscore: '../../shops_common/js/lib/underscore.min',
dataTables: 'http://datatables.net/download/build/nightly/jquery.dataTables'
},
waitSeconds: 300
});
But $.fn.dataTable is always undefined...
Any idea why?
Thanks.
I found the solution after extensive research: Datatables is a named module you must use the name "datatables" in your require
I've read many answers and followed steps I could ( seems right to me) but still DevTools shows Backbone is not defined. error.
Here's how I use requirejs shim.
<script data-main="js/subject_main.js" src="js/libs/require.js"></script>
subject_main.js
require.config({
paths: {
bootstrap: '../libs/bootstrap.min',

backbone: '../libs/backbone',
text: '../libs/text',
json2: '../libs/json2',
templates: '../../templates'
},
shim: {
'boostrap':{
deps: ['jquery']
},
'backbone': {
deps: ['jquery', 'underscore'],
exports: 'Backbone'
},
'underscore': {
exports: '_'
}
}
});
require(['subjects', 'json2'], function(app) {
app.initialize();
});
subjects.js
define(['jquery', 'underscore', 'backbone', 'subject_router'], function($, _, Backbone, router) {
return {
initialize: function() {
Backbone.history.start();
}
};
});
subject_router
define([
'jquery',
'underscore',
'backbone',
'models/subject_item_model',
'collections/subjects_collection',
'views/subject_view'
],function($, _, Backbone) {
var AppRouter = Backbone.Router.extend({ ... });
return new AppRouter();
});
Chrome DevTools shows following sequence (order ) of scripts -
As you can see, backbone is loaded at very end. I don't know what's going wrong and where.
backbone.js or underscore.js look fine to me here, and indeed they are being loaded!
The 404s in your dev tool are referring to the source mapping files (underscore.min.map). You might want to look at this post: Missing Javascript ".map" file for Underscore.js when loading ASP.NET web page.
PS: In your subject_router code you have a mismatch on the arguments passed in to the module function.
I am trying to use the backbone-ui library but cannot figure out the require.js configuration to get the modules loaded.
main.js:
requirejs.config({
baseUrl: '/static/js/facebook_report_app/js',
paths: {
backbone: 'lib/backbone'
, underscore: 'lib/underscore'
, jquery: 'lib/jquery'
, laconic: 'lib/laconic'
, moment: 'lib/moment'
, backboneUI: 'lib/backbone-ui/js/backbone_ui'
, menuUI: 'lib/backbone-ui/js/menu'
, textUI: 'lib/backbone-ui/js/text_field'
, text: 'lib/text'
},
shim: {
'lib/underscore': {
exports: '_'
},
'laconic': {
deps: ["jquery"],
exports: "$.el"
},
'lib/backbone': {
deps: ['lib/underscore']
, exports: 'Backbone'
},
'backboneUI': {
deps: ['lib/backbone', 'laconic', 'jquery']
, exports: 'Backbone.UI'
},
'textUI': {
deps: ['jquery', 'lib/backbone', 'backboneUI', 'laconic']
, exports: 'Backbone.UI.TextField'
},
'menuUI': {
deps: ['lib/backbone', 'backboneUI', 'laconic', 'textUI']
, exports: 'Backbone.UI.Menu'
},
'lib/backgrid': {
deps: ['lib/underscore', 'lib/backbone']
, exports: 'Backgrid'
},
'report_app': {
deps: ['lib/underscore', 'lib/backbone', 'lib/backgrid', 'backboneUI']
}
}
});
require([
'facebook_report_app'
],
function(FacebookReportApp) {
window.fbReport = new FacebookReportApp();
});
menu_user.js
define(['jquery', 'lib/backbone', 'backboneUI', 'menuUI', 'laconic'], function(AccountPickerView) {
var AccountPickerView = Backbone.UI.Menu.extend({
el: '.left-nav',
});
return AccountPickerView;
});
When I load this in dev, the console reports "Object [object Object] has no method 'input' ", on line 44 of the text_field.js of the Backbone-UI library.
I suppose my configuration approach is broken to begin with -- I added the menu.js and text_field.js files bc I was getting errors 'Backbone.UI.Menu' and Backbone.UI.TextField' (a requirement of Menu) weren't defined. But there must be a cleaner way to bring in the various files of backbone-ui.
So how do I get rid of the 'no method input' error? Or better configure to use Backbone UI? Or should I be using jQuery UI in the first place? In which case, where do I go to figure out configuration of that?
I got it working, after much fiddling with the following setup:
js/main.js
requirejs.config({
baseURL: 'js',
urlArgs: "bust=" + (new Date()).getTime(),
shim: {
underscore: {
exports: '_'
},
jquery: {
exports: '$'
},
backbone: {
deps: ['underscore', 'jquery'],
exports: 'Backbone'
},
laconic: {
exports: '$.el'
},
backbone_ui: {
deps: ['underscore', 'jquery', 'backbone', 'laconic', 'moment'],
exports: 'Backbone.UI'
}
},
paths: {
jquery: 'http://cdnjs.cloudflare.com/ajax/libs/jquery/2.0.3/jquery.min',
moment: './lib/moment.min',
laconic: './lib/laconic',
underscore: 'http://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.4.4/underscore-min',
backbone: 'http://cdnjs.cloudflare.com/ajax/libs/backbone.js/1.0.0/backbone-min',
backbone_ui: './lib/backbone-ui',
crypto: 'http://crypto-js.googlecode.com/svn/tags/3.1.2/build/rollups/md5',
templates: '../templates',
collections: './collections',
models: './models',
}
});
js/views/json.js
define(['jquery','underscore', 'backbone', 'backbone_ui'],
function($,_,Backbone, BBUI){
var JsonView = Backbone.View.extend({
className: "json-item",
initialize: function(data){
var self = this;
this.app = data.app;
this.model = data.model;
this.listenTo(this.model, "change", function(){
console.log("model changed", self.model);
});
this.model.fetch({
success: function(){
self.render();
}
});
},
render: function(){
var self = this;
$(this.el).empty();
for (key in this.model.attributes){
this.el.appendChild(new Backbone.UI.Label({content:key}).render().el);
this.el.appendChild(new Backbone.UI.TextField({model: this.model, content:key}).render().el);
}
this.el.appendChild(new Backbone.UI.Button({content:"save", onClick: function(){self.model.save()}}).render().el);
return this;
}
});
return JsonView;
});
Please note that I import backbone-ui as BBUI and never reference it that way. BBUI.TextField() is a defined function and using it would work as well, but the way Backbone-ui is set up it makes alterations to Backbone, Jquery, and Underscore when it loads. So I figured I just needed it to be run prior to the view getting loaded.
I'm relatively new to Backbone and RequireJS, so please bear with me. I'm getting an error when I do the following in my collection: _.range(0,10). It's giving me this error:
Uncaught TypeError: Cannot call method 'range' of undefined
Somehow the "_" is not getting resolved when my Collection is loaded. Here's my collection below:
define([
'jquery',
'underscore',
'backbone',
'collections/feed',
'text!/static/templates/shared/display_item.html'
], function($, _, Backbone, FeedCollection, DisplayItem){
debugger; // Added this to test the value of _
var FeedView = Backbone.View.extend({
el: '#below-nav',
initialize: function () {
this.feedCollection = new FeedCollection();
},
feed_row: '<div class="feed-row row">',
feed_span8: '<div class="feed-column-wide span8">',
feed_span4: '<div class="feed-column span4">',
render: function () {
this.loadResults();
},
loadResults: function () {
var that = this;
// we are starting a new load of results so set isLoading to true
this.isLoading = true;
this.feedCollection.fetch({
success: function (articles) {
var display_items = [];
// This line below is the problem...._ is undefined
var index_list = _.range(0, articles.length, 3);
_.each(articles, function(article, index, list) {
if(_.contain(index_list, index)) {
var $feed_row = $(that.feed_row),
$feed_span8 = $(that.feed_span8),
$feed_span4 = $(that.feed_span4);
$feed_span8.append(_.template(DisplayItem, {article: articles[index]}));
$feed_span4.append(_.template(DisplayItem, {article: articles[index+1]}));
$feed_span4.append(_.template(DisplayItem, {article: articles[index+2]}));
$feed_row.append($feed_span8, $feed_span4);
$(that.el).append($feed_row);
}
});
}
});
}
});
return FeedView;
});
I added the debugger line so that I could test the values of all the arguments. Everything loaded fine, except for _. Could this be something wrong with my config.js file?
require.config({
// Set base url for paths to reference
baseUrl: 'static/js',
// Initialize the application with the main application file.
deps: ['main'],
paths: {
jquery: 'libs/jquery/jquery.min',
require: 'libs/require/require.min',
bootstrap: 'libs/bootstrap/bootstrap.min',
text: 'libs/plugins/text',
underscore: 'libs/underscore/underscore',
backbone: 'libs/backbone/backbone',
json: 'libs/json/json2',
base: 'libs/base/base'
},
shim: {
'backbone': {
// These script dependencies should be loaded first before loading
// backbone
deps: ['underscore', 'jquery'],
exports: 'Backbone'
},
'bootstrap': {
deps: ['jquery'],
exports: 'Bootstrap'
}
}
})
Your help is greatly appreciated. My head is spinning as a result of this error.
Based off the project that I'm working on, you need a shim for underscore as well. Underscore isn't 'exported' per say, so use this instead:
shim: {
'backbone': {
// These script dependencies should be loaded first before loading
// backbone
deps: ['underscore', 'jquery'],
exports: 'Backbone'
},
'bootstrap': {
deps: ['jquery'],
exports: 'Bootstrap'
},
'underscore': {
exports: '_'
}
}
Seems this might also be 'duplicate' question of Loading Backbone and Underscore using RequireJS - one or two of the answers down the list there is a mention of this setup.
I have an underscore JS template and a jQuery plug-in that depends on the markup that gets rendered after the template is visible, but the problem is when I use jQuery document ready, it doesn't get the HTML that is rendered.
I used domReady but still ain't working, how can I accomplish this probably? This is what I got so far:
main.js
requirejs.config({
baseUrl: 'js/modules',
shim: {
// 'jquery.colorize': ['jquery'],
// 'jquery.scroll': {
// deps: ['jquery'],
// exports: 'jQuery.fn.colorize'
// },
'backbone': {
deps: ['underscore', 'jquery'],
exports: 'Backbone'
},
'underscore': {
deps: ['jquery'],
exports: '_'
}
},
paths: {
'jquery': '../libs/jquery',
'underscore': '../libs/underscore',
'backbone': '../libs/backbone',
'text': '../libs/text',
'views': '../views',
'templates': '../../templates',
'domReady': '../libs/domReady',
'ui': '../ui'
}
});
requirejs(['homeView', 'ui/placeholder'], function(Main){
Main.initialize();
});
homeView.js
define(['jquery', 'underscore', 'backbone', 'text!templates/home.html'], function($, _, Backbone, homeTemplate){
var HomeView = Backbone.View.extend({
el: $("#application"),
events: function(){
// Empty.
},
initialize: function(){
// Empty.
},
render: function(){
$('body').addClass('pt-dark');
$(this.el).html(_.template(homeTemplate, {}));
}
});
return new HomeView;
});
ui/placeholder.js
requirejs(['domReady', 'jquery'], function(doc, $){
doc(function(){
// Empty should contain the template html at this point.
console.log($('body').html());
});
});
Thanks a lot for help!
Try this:
define(['jquery', 'underscore', 'backbone', 'text!templates/home.html'], function($, _, Backbone, homeTemplate){
var HomeView = Backbone.View.extend({
el: $("#application"),
template: _.template(homeTemplate),
events: function(){
// Empty.
},
initialize: function(){
// Empty.
},
render: function(){
$('body').addClass('pt-dark');
this.$el.html(this.template({})));
jQuery('#the_thing_you_need', this.$el).theFunctionYouNeed();
}
});
return new HomeView;
});
Note that you should define a local attribute to the view called 'template' or something of that sort to store your template in and not re-call _.template every time that you need it.
Also, instead of jQuery(this.el) you can use this.$el.
