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'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 $.ModuleNamespace.containerMasonry;
});
I am trying to use the backbone-ui library but cannot figure out the require.js configuration to get the modules loaded.
main.js:
requirejs.config({
baseUrl: '/static/js/facebook_report_app/js',
paths: {
backbone: 'lib/backbone'
, underscore: 'lib/underscore'
, jquery: 'lib/jquery'
, laconic: 'lib/laconic'
, moment: 'lib/moment'
, backboneUI: 'lib/backbone-ui/js/backbone_ui'
, menuUI: 'lib/backbone-ui/js/menu'
, textUI: 'lib/backbone-ui/js/text_field'
, text: 'lib/text'
},
shim: {
'lib/underscore': {
exports: '_'
},
'laconic': {
deps: ["jquery"],
exports: "$.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 going a bit crazy here. I'm trying to use Grunt to go through a large RequireJS-based project and combine and minify the results during the deployment process. Here is my grunt process (using grunt-contrib-requirejs):
requirejs: {
compile: {
options: {
baseUrl: "public/js",
mainConfigFile: "public/js/config.js",
name: 'config',
out: "public/js/optimized/script.min.js",
preserveLicenseComments: false
}
}
}
Initially, I was taking the outputted script and placing it in the HTML -- but this lead to the 'define is undefined' error that means that RequireJS wasn't evoked. So instead, I'm putting in the HTML like this:
<script data-main="js/optimized/script.min" src="js/vendor/require.js"></script>
However, now I'm only getting a blank page.
The closest thing I can find out there that sounds like this is here, but's not being super helpful right now. For reference, I was using this as a starting point of my project -- however, when I run it, everything seems to be working for them but I can't find the differences.
Here is my config.js file:
require.config({
//Define the base url where our javascript files live
baseUrl: "js",
//Increase the timeout time so if the server is insanely slow the client won't burst
waitSeconds: 200,
//Set up paths to our libraries and plugins
paths: {
'jquery': 'vendor/jquery-2.0.3.min',
'underscore': 'vendor/underscore.min',
'backbone': 'vendor/backbone.min',
'marionette': 'vendor/backbone.marionette',
'mustache': 'vendor/mustache.min',
'bootstrap': 'vendor/bootstrap.min',
'bootbox': 'vendor/bootbox.min',
'jquery-ui': 'vendor/jquery-ui-1.10.2',
'app-ajax': '../conf/app-ajax',
'common': 'common',
'moment': 'vendor/moment.min'
},
//Set up shims for non-AMD style libaries
shim: {
'underscore': {
exports: '_'
},
'backbone': {
deps: ['underscore', 'jquery'],
exports: 'Backbone'
},
'marionette': {
deps: ['backbone', 'underscore', 'jquery'],
exports: 'Marionette'
},
'mustache': {
exports: 'mustache'
},
'bootstrap': {
deps: ['jquery']
},
'bootbox': {
deps: ['jquery', 'bootstrap'],
exports: 'bootbox'
},
'jquery-ui': {
deps: ['jquery']
},
'jquery-layout': {
deps: ['jquery', 'jquery-ui']
}
}
});
//Initalize the App right after setting up the configuration
define([
'jquery',
'backbone',
'marionette',
'common',
'mustache',
'bootbox',
'controllers/GlobalController',
'routers/GlobalRouter'
],
function ($, Backbone, Marionette, Common, Mustache, bootbox) {
//Declare ECMAScript5 Strict Mode first and foremost
'use strict';
//Define the App Namespace before anything else
var App = Common.app_namespace || {};
//Create the Marionette Application
App.Application = new Marionette.Application();
//Add wrapper region, so we can easily swap all of our views in the controller in and out of this constant
App.Application.addRegions({
wrapper: '#wrapper'
});
// Set up Initalizer (this will run as soon as the app is started)
App.Application.addInitializer(function () {
//Reach into Marionette and switch out templating system to Mustache
Backbone.Marionette.TemplateCache.prototype.compileTemplate = function (rawTemplate) {
return Mustache.compile(rawTemplate);
};
var globalController = new App.Controllers.GlobalController();
var globalRouter = new App.Routers.GlobalRouter({
controller: globalController
});
//Start Backbone History
Backbone.history.start();
});
//Start Application
App.Application.start();
}
);
Okay, so this is the crazy simple fix:
In the module that's declared after the require.config, use 'require' instead of 'define' when declaring the module.
If you use 'define', it added 'config' as a dependency of that module, which broke the whole thing. Craziness!
I'm trying to use both Underscore and Underscore.string with RequireJS.
Contents of main.js:
require.config({
paths: {
'underscore': '//cdnjs.cloudflare.com/ajax/libs/underscore.js/1.4.4/underscore-min',
'underscore-string': '//cdnjs.cloudflare.com/ajax/libs/underscore.string/2.3.0/underscore.string.min',
},
shim: {
'underscore': {
exports: '_'
},
'underscore-string': {
deps: ['underscore'],
exports: '_s'
},
}
});
var modules = ['underscore-string'];
require(modules, function() {
// --
});
Browser sees the _, but doesn't see the _s - it is undefined.
Ideally i want to have Underscore under _ and Underscore.string under _.str, but _ and _s are fine too. How can i do that?
Versions: RequireJS 2.1.5, Underscore 1.4.4, Underscore.string 2.3.0
Note: Thanks to #jgillich make sure, that paths have two slashes (//cdnjs.cloudfare.com/...), otherwise the browser would think that URL is relative to the server, and Firebug will throw:
Error: Script error
http://requirejs.org/docs/errors.html#scripterror
I found the error. For some reason RequireJS doesn't work with version of Underscore.string from cdnjs.com, so i replaced it with Github version. I guess it has something to do with the commit 9df4736.
Currently my code looks like the following:
require.config({
paths: {
'underscore': '//cdnjs.cloudflare.com/ajax/libs/underscore.js/1.4.4/underscore-min',
'underscore-string': '//raw.github.com/epeli/underscore.string/master/dist/underscore.string.min',
},
shim: {
'underscore': {
exports: '_'
},
'underscore-string': {
deps: ['underscore'],
},
}
});
var modules = ['underscore', 'underscore-string'];
require(modules, function(_) {
// --
});
Underscore.string resides in _.str.
Edit: As of 16 July 2013 the CDNJS version is updated with the upstream.
Battling with this for hours before i understand what i was doing wrong
This is what i did wrong
You should not rename the file underscore.string in main.js
even though in my library i did rename the file in paths i name it back to 'underscore.string'
This is how your main.js should look like
require.config({
paths: {
underscore: 'lib/underscore',
'underscore.string' : 'lib/_string' ,
},
shim: {
underscore: {
exports: '_',
deps: [ 'jquery', 'jqueryui' ]
},
'underscore.string': {
deps: [ 'underscore' ]
},
}
....
You could then either add it as dependency with in your shim like i did for my mixin file
shim: {
mixin : {
deps: [ 'jquery', 'underscore', 'underscore.string' , 'bootstrap' ]
},
Or just define it in your different pages like
/*global define */
define([
'underscore.string'
], function ( ) {
it just work now you can access it through _.str or _.string
This is why you should do it this way and not try to name it something else
on line 663 of underscore.string.js
// Register as a named module with AMD.
if (typeof define === 'function' && define.amd)
define('underscore.string', [], function(){ return _s; });
Which means that it will only register it with AMD require JS if you are defining 'underscore.string'
works for my ONLY if I use exact "underscore.string" module name in shim. Seems related to hardcoded name in underscore.string itself
Exempt from underscore.string source code (this branch is executed when require used):
// Register as a named module with AMD.
if (typeof define === 'function' && define.amd)
define('underscore.string', [], function(){ return _s; });
So for me the only working configuration is:
require.config({
paths: {
'underscore': '//cdnjs.cloudflare.com/ajax/libs/underscore.js/1.4.4/underscore-min',
'underscore.string': '//raw.github.com/epeli/underscore.string/master/dist/underscore.string.min',
},
shim: {
'underscore': {
exports: '_'
},
'underscore.string': {
deps: ['underscore'],
},
}
});
var modules = ['underscore', 'underscore.string'];
require(modules, function(_) {
// --
});
Here's a working code using Requirejs "order" plugin, also includes Jquery, and everything loads without any conflict:
requirejs.config({
baseUrl: "assets",
paths: {
order: '//requirejs.org/docs/release/1.0.5/minified/order',
jquery: 'http://code.jquery.com/jquery-2.1.0.min',
underscore: '//underscorejs.org/underscore-min',
underscorestring: '//raw.githubusercontent.com/epeli/underscore.string/master/dist/underscore.string.min',
underscoremixed: 'js/underscore.mixed' // Create separate file
},
shim: {
underscore: { exports: '_' },
underscorestring: { deps: ['underscore'] }
}
});
require(['order!jquery','order!underscoremixed'], function($,_) {
// test
console.log( _.capitalize('capitalized text') );
});
Inside js/underscore.mixed.js put the following...
define(['underscore','underscorestring'], function() {
_.mixin(_.str.exports());
return _;
});
Cheers! :)
I have an underscore JS template and a jQuery plug-in that depends on the markup that gets rendered after the template is visible, but the problem is when I use jQuery document ready, it doesn't get the HTML that is rendered.
I used domReady but still ain't working, how can I accomplish this probably? This is what I got so far:
main.js
requirejs.config({
baseUrl: 'js/modules',
shim: {
// 'jquery.colorize': ['jquery'],
// 'jquery.scroll': {
// deps: ['jquery'],
// exports: 'jQuery.fn.colorize'
// },
'backbone': {
deps: ['underscore', 'jquery'],
exports: 'Backbone'
},
'underscore': {
deps: ['jquery'],
exports: '_'
}
},
paths: {
'jquery': '../libs/jquery',
'underscore': '../libs/underscore',
'backbone': '../libs/backbone',
'text': '../libs/text',
'views': '../views',
'templates': '../../templates',
'domReady': '../libs/domReady',
'ui': '../ui'
}
});
requirejs(['homeView', 'ui/placeholder'], function(Main){
Main.initialize();
});
homeView.js
define(['jquery', 'underscore', 'backbone', 'text!templates/home.html'], function($, _, 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.
