I've tried to deploy my Durandal based solution. But I'm getting the following error once deployed.
Uncaught ReferenceError: requirejs is not defined main.js:1
(anonymous function)
I explored the files that got deployed with the projects, and require was included in the solution/path. The files have been deployed along with them. All that is different between the development and production copy is that my java script files get compressed. My next step is to see if this is related to the issue in any way?
Update:
I found the source of the problem to be the following:
<body>
<div id="applicationHost">
#Html.Partial("_splash")
</div>
#Scripts.Render("~/scripts/vendor")
#if (HttpContext.Current.IsDebuggingEnabled)
{
<script type="text/javascript" src="~/App/durandal/amd/require.js" data-main="#Url.Content("~/App/main")"></script>
}
else
{
<script type="text/javascript" src="~/App/main.js"></script>
}
</body>
If i remove the IsDebuggingEnabled check, and just leave the following it all works (obviously)
<script type="text/javascript" src="~/App/durandal/amd/require.js" data-main="#Url.Content("~/App/main")"></script>
As far as I remember, I haven't touched this code (created on initial project setup by template). So should all be as is from the Durandal VSX template.
Any idea why require would be removed during a non debugging deployment? :/
Durandal 1.2 comes with an optimizer.exe (http://durandaljs.com/documentation/Optimizing-On-Dot-Net/) that creates a optimized version main-built.js that has either Almond (default) or RequireJS bundled. The example above tries to load the source main.js that's why the error is thrown.
After running optimizer.exe successfully the code should be changed to this.
...
else
{
<script type="text/javascript" src="~/App/main-built.js"></script>
}

Looking at the documentation for installing Swagger-UI one can see that two official npm modules are being published: swagger-ui and swagger-ui-dist. However, I really struggle to figure out how these are supposed to be used with an already existing OpenApi 3.0 specification.
The only thing I need is a simple web application (plain node.js or express.js or whatever works) which will serve my existing specification.yml document embedded into the plain Swagger-UI files on a path like /docs.
Since this needs to be done in a repeatable manner (will run in a Docker container in the end), manual editing of files is not desired in the process.
The closest I could get was downloading a release tar ball, extracting the dist folder, use tools like sed to replace the default specification file with my own one and finally host this on a webserver like nginx.
However, this looks unnecessary complex to me and makes me wonder what the npm modules are supposed to be used for.
Finally I found two approaches to achieve my goal as outlined in the question.
Using unpkg
unpkg is an automated content delivery network for all modules that are published on the npm registry. It allows to include and use any npm module in a static HTML file without any complex package managers, dependency resolvers etc. This is especially great if you don't have any other need to use the npm ecosystem directly.
For swagger-ui, such an HTML file would look like this. Note that we are importing the swagger-ui-dist package which already includes all necessary dependencies.

<link rel="stylesheet" type="text/css" href="https://unpkg.com/swagger-ui-dist#3/swagger-ui.css" >
</head>
<body>
<div id="swagger-ui"></div>
<script src="https://unpkg.com/swagger-ui-dist#3/swagger-ui-bundle.js"> </script>
<script type="text/javascript">
window.onload = function() {
// Swagger-ui configuration goes here.
// See further: https://github.com/swagger-api/swagger-ui/blob/master/docs/usage/configuration.md
SwaggerUIBundle({
deepLinking: true,
dom_id: '#swagger-ui',
showExtensions: true,
showCommonExtensions: true,
url: specification.json // <-- adjust this to your webserver's structure
});
};
</script>
</body>
</html>
Host this HTML file on your webserver and your all settled.
Using browserify / webpack
browserify and webpack are module bundlers from the npm ecosystem that can collect an npm module and all its dependencies, then bundle them up in one single js file. This file can then be loaded and used in an HTML page.
While both tools might differ feature-wise in the details, for this job both of them work almost in the same way. The following example uses browserify, however, the general approach with webpack is the same.
First, install browserify globally:
npm install -g browserify
Then, install the swagger-ui module locally in your current folder:
npm install --save swagger-ui
Finally, bundle the swagger-ui module and all of its dependencies into a single output file:
browserify --require swagger-ui -o bundle.js
The according HTML page to include it could look like this:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link rel="stylesheet" href="./node_modules/swagger-ui/dist/swagger-ui.css">
<title>Swagger-UI</title>
</head>
<body>
<div id="swagger-ui"></div>
</body>
<script type="text/javascript" src="./bundle.js"></script>
<script type="text/javascript">
window.onload = function() {
// Swagger-ui configuration goes here.
// See further: https://github.com/swagger-api/swagger-ui/blob/master/docs/usage/configuration.md
SwaggerUI({
deepLinking: true,
dom_id: '#swagger-ui',
showExtensions: true,
showCommonExtensions: true,
url: specification.json // <-- adjust this to your webserver's structure
});
};
</script>
</html>
This approach might be preferred if you are using browserify or webpack within your ecosystem for other tasks anyway.
If you are looking for whatever works the easiest solution will be to use an existing swagger-ui like the demo store and pass your spec in the url param:
http://petstore.swagger.io/?url=https://raw.githack.com/heldersepu/hs-scripts/master/swagger/4411/7.json
If you want more of a standalone solution copy the swagger-ui dist directory to your deployment:
https://github.com/swagger-api/swagger-ui/tree/master/dist
then tweak the index.html to suit your needs
I am writing a WebRTC application and have the following problem:
I want to use the adapter.js library.
I have the following index.html:
<html>
<header>
<script src='../out/adapter.js'></script>
<script src='../out/main.js'></script>
</header>
<body>
<video id="localVideo" width='500' autoplay></video>
</body>
</html>
and my main.js looks like:
var adapter=require('webrtc-adapter');
var localVideo=document.querySelector('video#localVideo');
navigator.getUserMedia(media_constraints, handleUserMedia, handleUserMediaError);
function handleUserMedia(stream) {
localStream = stream;
adapter.attachMediaStream(localVideo, stream);
console.log('Adding local stream.');
}
but my browser logs the error: Uncaught ReferenceError: require is not defined
require is used (and defined) in Node.js environments to load modules. (Not exclusively, for more information check here).
If you downloaded an adapter.js version from here and include it the way you do (via script tags), you can simple delete the require(...) line and you should be good to go.
Edit: added an example
console.log(adapter.browserDetails.browser);
<script src="http://webrtc.github.io/adapter/adapter-latest.js"></script>
if you have checked installing adapter js?
check
npm webrtc-adapter --version
if not showing up in node, install it to your app
npm install --save webrtc-adapter
My socket.js file can not be found when my Node.js server runs on Heroku, however when it runs on localhost, it is found. In addition, although the app.js file is in the same directory with socket.js file, it can not be found. I've seen some posts suggesting to use
app.use('/', express.static(__dirname));
but i guess it is not the case here.
my index.html file :
<script src="/angular-socket-io/socket.js"></script>
<script src="/socket.js"></script>
<script src="/socket.io/socket.io.js"></script>
Amongst them, the only one couldnt be found is the second directory(/socket.js) which contains the 'socket factory'inside.
My folder tree is as follows;
-app
--assets
---app.js
---socket.js
Any help please?
Just add app.use(express.static(path.join(__dirname, 'app/assets'))); to your main code and after that you can use <script src="/socket.js"></script>
My JavaScript file didn't initialize because of how I imported the JQuery script inside of my index.html.
If your JavaScript file that contains JQuery is not initialized. Make sure to import it with HTTPS not HTTP.
WRONG :
<script src="http://code.jquery.com/jquery-3.5.1.js"></script>
CORRECT :
<script src="https://code.jquery.com/jquery-3.5.1.js"></script>
This solved my problem of missing the JavaScript file on Heroku.
I have been building and debugging an Angular.JS application for several months now running from a browser without any issues whatsoever, however I am now in the stages of packaging it to run in node wrapper. When i created my package.json and ran the folder from nw.exe I get an error that says:
Uncaught node.js Error
ReferenceError: angular is not defined
at file:///C:/wamp/www/Maintenence/ng/ng-init.js:2:11
now the code line it has a problem with in ng-init.js is
var app = angular.module('MaintenenceApp', ['ngRoute']);
It doesnt like angular in angular.module and once I received this error I went to the angular.js docs to make sure i hadnt done something wrong here and according to https://docs.angularjs.org/guide/module this code is 100% correct.
what could be causing this error. as i mentioned, it runs perfectly in a web browser with no errors in js console.
package.json
{
"main": "index.html",
"name": "Maintenence Manager",
"version": "0.0.1",
"window": {
"toolbar": false,
"frame" : true
}
}
here is the order of my scripts in the head of index.html index.html
<didnt seem important to show css links and such but jquery is also in the page>
<script type="text/javascript" src="//code.angularjs.org/1.3.0-rc.0/angular.js"></script>
<Script type="text/javascript" src="//code.angularjs.org/1.3.0-rc.0/angular-route.js"></Script>
<script type="text/javascript" src="ng/ng-init.js"></script>
Thanks in advance.
As it turns out, Node Webkit doesn't support src="//url.com" which i use so the http/https thing doesn't become in issue.
Replacing the urls for the scripts with src="http://url.com" fixed my issue.

Hello, I would like to build ember.js using Ubuntu 13.
I have cloned the official Github project, cd into the project and as described in the readme file I did:
bundle install
rake dist
no error is shown on screen and as a result I get a directory shown in the image
I would like to use ember and ember-data, so I include
ember.js
ember-data-deps.js
files in my test project.
The problem is that I am getting a TypeError: App.Router is undefined
I am using this at my client.js file to init ember
this.App = Ember.Application.create();
App.Router.map(function() {
this.route('contributors');
this.route('contributor', {path: '/contributors/:contributor_id'});
});
Am I doing something wrong in the build process?
Should I include some other js files in my project?
Thank you in advanced.
The TypeError: App.Router is undefined error is because ember.js is not loaded correctly or in the correct order.
To get ember-data (that is separate from ember.js) you have to clone this repo (https://github.com/emberjs/data) and follow the build instructions in the readme file, it's straight forward, and once you have the dist directory from the ember-data build process get the file ember-data.js development version or ember-data.min.js for production (well, production... ember-data is still considered unstable for production environments).
here is a simple ember project setup using ember-data:
index.html
<!DOCTYPE HTML>
<html lang="en-US">
<head>
<meta charset="UTF-8">
<title>ember app</title>
</head>
<body>
<script type="text/x-handlebars">
hello world!
</script>
<script type="text/javascript" src="http://cdnjs.cloudflare.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<script type="text/javascript" src="http://builds.emberjs.com.s3.amazonaws.com/handlebars-1.0.0-rc.3.js"></script>
<script type="text/javascript" src="http://builds.emberjs.com.s3.amazonaws.com/ember-latest.js"></script>
<script type="text/javascript" src="http://builds.emberjs.com.s3.amazonaws.com/ember-data-latest.js"></script>
<script type="text/javascript" src="app.js"></script>
</body>
</html>
app.js
var App = Ember.Application.create({
ready: function () {
console.log("app started...");
}
});
hope it helps
