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']
}
}

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.
I am trying to load bootstrap and kendo-ui using requirejs but they both depend on jquery to be loaded first.
Currently all three scripts are loading async (from CDNs) with:
require.config({
paths: {
"jquery": [
"https://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min",
"libs/jquery"
],
'bootstrap': [
'http://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/js/bootstrap.min',
'libs/bootstrap'
],
'kendo': [
'http://cdn.kendostatic.com/2014.1.416/js/kendo.ui.core.min',
'libs/kendo'
]
}
})
require(['jquery', 'bootstrap', 'kendo'], function () {
$('body').html('hi!')
})
How do get it to not load other scripts until jquery is loaded completely?
I assume there is a nicer way than:
require(['jquery'], function () {
require(['bootstrap', 'kendo'], function () {
$('body').html('hi!')
})
})
If that even works (off top of my head).
Try to use shim-option like,
require.config({
paths: {
'jquery': 'https://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min',
'bootstrap': 'http://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/js/bootstrap.min',
'kendo': 'http://cdn.kendostatic.com/2014.1.416/js/kendo.ui.core.min'
},
// Use shim for plugins that does not support ADM
shim: {
'bootstrap': ['jquery'],
'kendo': ['jquery']
}
});
Also, refer the example-of-jquery-shim
Using Require.js to load jquery-ui is giving me problems - jquery-ui's dependencies don't see m to be working. Here is the error:
Uncaught TypeError: Cannot read property 'ui' of undefined
Here are the two files:
main.js
require.config({
baseUrl: '/git-cake-skeleton/js',
paths: {
'jquery': 'lib/jquery-1.10.2',
'jqueryui': 'lib/jquery-ui-1.10.3.min',
'bootstrap': 'lib/bootstrap.min'
},
shim: {
'jqueryui': {
exports: '$',
deps: ['jquery']
},
'bootstrap': {
deps: ['jquery']
}
} });
require([
'jquery',
'widgets/demowidget'
], function ($) {
$(document).ready(function() {
// This is where we bind our widgets to stuff on the page. All the real logic happens inside widgets!
$(".app-js-demowidget").demowidget();
});
} );
demowidget.js
// Example of simple plugin inside Require.js framework
define(['jquery', 'jqueryui'], function ($) {
$.widget('skeleton.demowidget', {
options: {
},
_init: function() {
this.element.click(function(e){
alert('Hello world');
});
}
});
});
File structure:
|-js
| main.js
|---lib
| bootstrap.min.js
| jquery-1.10.2.js
| jquery-ui-1.10.3.min.js
| require.js
|---widgets
| demowidget.js
edit: as expected, switching 'jqueryui' with 'bootstrap' in demowidget.js gives the following error:
Bootstrap requires jQuery
You first need to define the jquery dependency:
define('jquery', [], function () { return root.jQuery; });
Then you can use 'jquery' to load other libs depending on jQuery.
I'm incorporating SignalR into a project where I'm already using require.js to handle my scripts dependencies.
I'm having a little trouble making sure "/signalr/hubs" is called after "jquery.signalR-1.1.2" loads.
I got it to work, but I'm wondering if there is a better alternative out there.
This is what I have:
require(["signalr"], function () {
require(["noext!/signalr/hubs"], function () {
//initialize and work with the hub here
}
}
Is there a way I can create a shim here to establish the dependency between signalr/hubs and the signalr script?
Thanks!
This works for me with SignalR 1.1.2:
require.config({
baseUrl: "/<your scripts dir>",
paths: {
"jquery": "jquery-<your jquery version>.min",
"signalr.core": "jquery.signalR-<your signalr version>.min",
"signalr.hubs": "/signalr/hubs?"
},
shim: {
"jquery": {
exports: "$"
},
"signalr.core": {
deps: ["jquery"],
exports: "$.connection"
},
"signalr.hubs": {
deps: ["signalr.core"],
}
}
});
require(["jquery", "signalr.hubs"],
function($)
{
var hubProxy = $.connection.myHub;
// ... go to town ...
});
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.
