Require JS, Loading Libraries through CDN fails

I have read the answer to this question require js loading scripts from cdn fail. But in my case it does not help. I have a require JS setup and I want to use CDN to load my libraries.
The Require JS documentation says below is the right way to load libs from CDN with a fallback to local files.
requirejs.config({
//To get timely, correct error triggers in IE, force a define/shim exports check.
enforceDefine: true,
paths: {
jquery: [
'http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min',
//If the CDN location fails, load from this location
'lib/jquery'
]
}
});
require(['jquery'], function ($) {
});
I am using the same method but I get an error instead, below is my code
requirejs.config({
baseUrl: location.protocol + '//' + location.host + '/app',
waitSeconds: 0,
paths: {
'jquery': ['https://cdnjs.cloudflare.com/ajax/libs/jquery/3.0.0-alpha1/jquery.min','/assets/js/vendor/jquery'],

I have just made the changes for Jquery as of now and I am giving both CDN URL and local path but when I load my page I get an error
TypeError: $el.siblings is not a function
Adding on
I am using Require JS for loading my libs but then at the production I am using almond, which combines all modules into one single file, so has this something to do with the error ?
Any help on this is highly appreciated. Thanks

Adding on I am using Require JS for loading my libs but then at the production I am using almond, which combines all modules into one single file, so has this something to do with the error ?
Yes, it does. Almond cannot do dynamic loading. In other words, everything you want Almond to load must be into a single bundle of modules. You cannot use a CDN with Almond.
"No dynamic loading" is the first restriction in its list of restrictions.

Marionette v2.2 upgrade error - Cannot read property 'ChildViewContainer' of undefined

I've started a new backbone, marionette and require project using version 2.2 (i previously worked with 1.8) It seems a lot has changed. I'm getting an error when the browser loads marionette:
Uncaught TypeError: Cannot read property 'ChildViewContainer' of undefined
This is my main.js file:
require.config({
baseURL: 'scripts',
paths: {
"jquery": "lib/jquery",
"underscore": "lib/underscore",
"backbone": "lib/backbone",
"marionette": 'lib/backbone.marionette',
"templates": "../templates",
"text": "lib/text"
},
shim: {
underscore: {
exports: '_'
},
backbone: {
deps: ['underscore', 'jquery'],
exports: 'Backbone'
},
marionette: {
deps: ['jquery', 'underscore', 'backbone'],
exports: 'Marionette'
},
waitSeconds: 15
}
});
require([ "app", "marionette"], function(App, marionette) {
App.start();
});
And this is my app.js file:
define(["marionette", "router"], function (Marionette, AppRouter) {
var MyApp = Marionette.Application.extend({
initialize: function(options) {
console.log("options.container");
}
});
var MyApp = new MyApp({container: '#page'});
MyApp.addInitializer(function (options) {
MyApp.Router = new AppRouter();
Backbone.history.start();
});
// export the app from this module
return MyApp;
});

Just look at your backbone.js file. It's empty. Download backbone.js from http://backbonejs.org/ and replace it.

I just ran into this same issue myself. The issue was multiple instances of Marionette being included on the page. (i had errantly placed a script tag for marionette on the page from cdnjs, as well as trying to include the static file locally via require). removing the reference to the external JS file helped me...

How to optimize ember-data with r.js

I recently switched to ember-data#canary, then r.js started failing.
[Error: Error: ENOENT, no such file or directory
'/scripts/lib/ember-data/ember-data/core.js'
In module tree:
app/main
app/app
ember-data
at Object.fs.openSync (fs.js:427:18)
]
This is the build configuration file
`File: build.js`
var config = {
mainConfigFile: '/scripts/common.js',
}
This is the requirejs configuration file
requirejs.config({
paths: {
ember: 'ember/ember',
jquery: 'jquery/dist/jquery',
requirejs: 'requirejs/require',
handlebars: 'handlebars/handlebars',
'ember-data': 'ember-data/ember-data',
},
shim: {
ember: {
deps: [
'handlebars',
'jquery'
],
exports: 'Ember'
},
'ember-data': {
deps: [
'ember'
],
exports: 'DS'
},
}
});
This is how i use ember-data:
define(['ember', 'ember-data'], function(Ember, DS) {
});
You can see the ember-data canary builds here.

This bug have meet from ember-data 1.0.0-beta.9, because in this version has been updated function require in sources. You can revert to beta.8 or try to fix this problem with plugin derequire (grunt-derequire, gulp-derequire).
I've fix it with this task:
gulp.task('build-derequire', function() {
return gulp.src([paths.src.common + '/bower_components/**/ember-data*.js'])
.pipe($.derequire([
{
from: 'require',
to: '_dereq_'
},
{
from: 'define',
to: '_defi_'
}
]))
.pipe(gulp.dest(paths.dev_dist + '/scripts/lib'));
});

Trouble getting signalR to work with requireJS

I am having difficulty trying to get signalr to work with requirejs. This is my code I have but I get the following error:
_Uncaught Error: SignalR: Error loading hubs. Ensure your hubs reference is correct, e.g. <script src='/signalr/hubs'></script>._
Code:
<script src="~/Scripts/jquery.signalR-1.0.0-rc2.js"></script>
<script src="~/signalr/hubs"></script>
<script type="text/javascript">
// requirejs configuration setup
requirejs.config({
baseUrl: '#string.Format("{0}://{1}{2}Scripts/modules", Request.Url.Scheme, Request.Url.Authority, Url.Content("~"))', // this might need to change as it depends on the number of / in the url...?
paths: {
'jquery': '../jquery-1.9.0',
'bootstrap': '../bootstrap',
'knockout': '../knockout-2.2.1',
'noext': '../noext',
'sigr': '../jquery.signalR-1.0.0-rc2'
},
shim: {
"sigr": {
deps: ['jquery']
},
"noext!signalr/hubs": {
deps: ['sigr']
}
}
});
Does anyone have any ideas as to why or how I can get this to work?

I was able to get require to work with requirejs..I followed the tutorial on http://requirejs.org/docs/jquery.html on how to plugin jquery and added signal references for this to work
require(["jquery", "jquery.alpha", "jquery.beta","jquery.signalr-1.0.0-rc2","/signalr/hubs"],
function($) {
}
);
I think you have to modify your configuration to do either of the following
Option1:
paths: {
'jquery': '../jquery-1.9.0',
'bootstrap': '../bootstrap',
'knockout': '../knockout-2.2.1',
'noext': '../noext',
'sigr': '../jquery.signalR-1.0.0-rc2'
'hubs': '/signalr/hubs'
},
Option2:
shim: {
"sigr": {
deps: ['jquery']
},
"noext!**/**signalr/hubs": {
deps: ['sigr']
}
}

Sequential loading of scripts in require.js and use.js

I'm using in my project require.js and it's plugin use.js.
require.config({
// Initialize the application with the main application file
deps: ["main"],
paths: {
// JavaScript folders
libs: "../assets/js/libs",
plugins: "../assets/js/plugins",
// Libraries
jquery: "../assets/js/libs/jquery",
underscore: "../assets/js/libs/underscore",
backbone: "../assets/js/libs/backbone",
jqueryUI: "../assets/js/libs/jqueryUI",
jquerySlider: "../assets/js/libs/slider",
jqueryMouseWheel: "../assets/js/libs/jquery.mousewheel",
jquerySelectBox: "../assets/js/libs/selectBox",
jqueryMouse: "../assets/js/libs/mouse",
bookReader: "../assets/js/libs/newReader",
// Shim Plugin
use: "../assets/js/plugins/use"
},
use: {
backbone: {
deps: ["use!underscore", "jquery"],
attach: "Backbone"
},
underscore: {
attach: "_"
},
jqueryUI: {
deps: ["jquery"]
},
jquerySlider: {
deps: ["jquery", "jqueryMouse"]
},
jquerySelectBox: {
deps: ["jquery"]
},
jqueryMouse: {
deps: ["jquery", "jqueryUI"]
},
jqueryMouseWheel: {
deps: ["jquery", "jqueryUI"]
},
bookReader: {
deps: ["jquery", "jqueryUI", "jqueryMouse", "jquerySlider", "jqueryMouseWheel", "jquerySelectBox"],
attach: "Reader"
}
}
});
The problem is that scripts start load simultaneously, and because of that there are unmet dependencies, often there are these two errors
Uncaught TypeError: Object function (a, b) {return new e.fn.init (a, b, h)} has no method 'widget': 4444/assets/js/libs/mouse.js: 15
Uncaught TypeError: Cannot read property 'mouse' of undefined: 4444/assets/js/libs/slider.js: 20
Once the files are in the cache, the problem no longer occurs.
So, my question. How do I specify that the script must loaded consistently?
It is possible to build scripts that wrap them into one file. But this option is not very desirable
Thank you!

Have a look at this AMD loader plugin called STEP, it allows you to load scripts in sequential order.
