Backbone.js not working with Require.js bundle - javascript

I can't get Backbone.js to play nicely with require.js' bundle system.
This works:
requirejs.config({
baseUrl: 'assets/',
bundles: {
corejs: ['jquery', 'underscore']
},
paths: {
corejs: '../core',
jquery: '../static/js/jquery',
backbone: '../static/js/backbone',
underscore: '../static/js/underscore',
knockout: '../static/js/knockout',
knockback: '../static/js/knockback'
},
shim: {
backbone: {
deps: ['underscore', 'jquery'],
exports: 'Backbone'
}
},
deps: ['corejs']
});
require(['app/app'], function(App) {
App.initialize();
});
Changing bundles to be
bundles: {
corejs: ['jquery', 'underscore', 'backbone']
}
results in a require.js timeout
core.js currently consists of concatted jQuery, Underscore, Backbone
Backbone is available on the browser console, even before the timeout.

As #ivarni mentioned in the comments, Backboone has had CommonJS support added:
// Next for Node.js or CommonJS. jQuery may not be needed as a module.
} else if (typeof exports !== 'undefined') {
var _ = require('underscore'), $;
try { $ = require('jquery'); } catch(e) {}
factory(root, exports, _, $);
which means that if you use a recent version of Backbone you can just require it normally without having to create a shim.

requirejs include multiple extensions for jquery control

How do you load other extensions for a jquery control called 'fancytree' I'm trying to get fancytee to load or include the fancytree.table.js and other extensions that are needed - below is my config
require.config({
shim: {
underscore: {
exports: '_'
},
backbone: {
deps: [
'underscore',
'jquery'
],
exports: 'Backbone'
},
'jquery-ui': {
exports: "$",
deps: ['jquery']
},
'fancytree': {
deps: ['jquery-ui']
},
'alertify': {
deps: ['jquery']
},
'fancytreetable': {
deps: ['jquery', 'fancytree']
}
},
paths: {
'jquery': '../lib/jquery/jquery',
'underscore': '../lib/underscore/underscore',
'backbone': '../lib/backbone/backbone',
'text': '../lib/text/text',
'jquery-ui': '../vendor/jquery-ui/jquery-ui',
'fancytree': [
'../vendor/fancytree/fancytree',
'../vendor/fancytree/fancytree.table'/* this extension here needs to be added but it's not included */
],
'alertify': '../vendor/alertify/alertify'
},
baseUrl: '/js/app',
});
Nikhil Mehta's comment points you in the right direction. Your paths value for fancytree is wrong. You use an array there when you want to provide fallback values for modules. If you give [A, B, C], for instance, if A fails to load, RequireJS tries B and if this fails, tries C. And if all fail, then that's a load failure.
Based on the configuration you show, you'd need:
fancytree: '../vendor/fancytree/fancytree',
fancytreetable: '../vendor/fancytree/fancytree.table'
You already have a shim that establishes that fancytreetable needs fancytree.
Note that unless you are using fairly old versions of Underscore and Backbone, you do not need to specify shim values for them. RequireJS is probably going to just ignore them but it may confuse people reading your code.
Here is how made it work, requirejs with jquery.fancytree-all and latest jquery-ui with AMD support, since working with individual extensions will require a lot of shimming.
onBuildWrite is optional but i prefer it this way
requirejs.config({
paths: {
'jquery': './js/vendor/jquery',
'jquery-ui': './js/vendor/jquery-ui',
'jquery.fancytree': './js/vendor/fancytree/jquery.fancytree-all'
},
shim: {
'jquery.fancytree': {
deps: ['jquery', 'jquery-ui/core', 'jquery-ui/effect', 'jquery-ui/effects/effect-blind', 'jquery-ui/widgets/draggable', 'jquery-ui/widgets/droppable'],
exports: 'jQuery.fn.fancytree'
}
},
onBuildWrite: function (moduleName, path, contents) {
'use strict';
if (moduleName === 'jquery.fancytree') {
contents = 'define( "jquery.fancytree", ["jquery", "jquery-ui/core", "jquery-ui/effect", "jquery-ui/effects/effect-blind", "jquery-ui/widgets/draggable", "jquery-ui/widgets/droppable"], function(jQuery) { ' + contents + '});';
}
return contents;
}
});
// usage
define([
'jquery',
'jquery.fancytree',
'css!./css/fancytree/skin-custom/ui.fancytree.css',
],
function($) {
'use strict';
//
$('#tree').fancytree({
checkbox: true,
source: [{title: 'Node 1'}, {title: 'Node 2',key: 'id2'}]
});
//
});

require.js shim for lib jquery, marionette, backbone, underscore

I used to link libraries :
shim: {
backbone: {
deps: ["jquery", "underscore"],
exports: "Backbone"
},
marionette: {
deps: ["backbone"],
exports: "Marionette"
},
angular: {
exports: "angular"
}
}
but now I have read that these libs uses AMD and shim property is not required! Is it?
main.js
paths: {
marionette: "backbone.marionette"
}
some.js
define( "util",
['marionette'],
function(Marionette){
//test arguments!
//console.log($)
//console.log(jQuery)
//console.log(Backbone)
//console.log(_)
console.log(Marionette) //exist!
}
);
If the third party scripts are not AMD compatible you have to use shims.
You might check if the scripts are AMD compatible if at the top the code does have something like this:
(function(root, factory) {
// Set up Backbone appropriately for the environment. Start with AMD.
if (typeof define === 'function' && define.amd) {
define(['underscore', 'jquery', 'exports'], function(_, $, exports) {
// Export global even in AMD case in case this script is loaded with
// others that may still expect a global Backbone.
root.Backbone = factory(root, exports, _, $);
});
// Next for Node.js or CommonJS. jQuery may not be needed as a module.
} else if (typeof exports !== 'undefined') {
var _ = require('underscore'), $;
try { $ = require('jquery'); } catch(e) {}
factory(root, exports, _, $);
// Finally, as a browser global.
} else {
root.Backbone = factory(root, {}, root._, (root.jQuery || root.Zepto || root.ender || root.$));
}
}(this, function(root, Backbone, _, $) {
// ....
}
And here is how look like for example the configuration file on one of my project:
shim: {
// jQuery Mobile
"jquerymobile": ["jquery"],
// Twitter Bootstrap jQuery plugins
"bootstrap": ["jquery"],
// jQueryUI
"jqueryui": ["jquery"],
// jQuery Cookie
"jquery.cookie": {
deps: ["jquery"],
exports: "jquery.cookie"
},
// jQuery easing functions
"jquery.easing" : {
deps: ["jquery"],
exports: "jquery.easing"
},
// Shim backbone to resolve conflicts on minification
"backbone": {
deps: ['underscore', 'jquery'],
init: function(_, $) {
return this.Backbone = Backbone.noConflict();
}
},
// Backbone.validateAll plugin that depends on Backbone
"backbone.validateAll": ["backbone"],
"backbone.paginator" : {
deps: ["backbone"],
exports : "Backbone.Paginator"
},
"backgrid" : {
deps : ['jquery', 'underscore', 'backbone'],
exports: "Backgrid"
},
"backgrid.paginator" : {
deps: ["backbone", "backgrid"],
exports : "Backgrid.Paginator"
}
}

RequireJS + Backbone without jQuery?

I'm trying to use RequireJS, here is my config file :
require.config({
baseUrl: "/scripts",
paths: {
zepto: "zepto.min",
underscore: "underscore.min",
backbone: "backbone.min"
},
shim: {
zepto: {
exports: "$"
},
underscore: {
exports: "_"
},
backbone: {
deps: ["underscore", "zepto"],
exports: "Backbone"
}
}
});
And this is my app.js :
require(['backbone'], function(Backbone) {
console.log('loaded!');
});
This works fine, but I don't know why RequireJS is trying to load jQuery.
Because Backbone requires module called jquery (look at top of backbone.js) file.
// Set up Backbone appropriately for the environment. Start with AMD.
if (typeof define === 'function' && define.amd) {
define(['underscore', 'jquery', 'exports'], function(_, $, exports) {
// Export global even in AMD case in case this script is loaded with
// others that may still expect a global Backbone.
root.Backbone = factory(root, exports, _, $);
});
and You haven't defined this module.
To hack this use zepto as jquery:
require.config({
baseUrl: "/scripts",
paths: {
jquery: "zepto.min",
underscore: "underscore.min",
backbone: "backbone.min"
},
shim: {
jquery: {
exports: "$"
},
underscore: {
exports: "_"
}
}
});
And second: shim only works with non-amd modules. Backbone is AMD module.

Getting blank page using RequireJS and Grunt

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!

Underscore.string with RequireJS

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! :)
