I am new to React and cypress. We are using Cypress script to cover React developed code. I am able to launch application in browser However when we use cy.visit('application url') then script fails with below error message :
ReferenceError: Handlebars is not defined
After getting this error I added handlebars dependency in package.json file and restarted server. This also didn't the problem. Any help on this will be greatly appreciated.

I'm trying to use tone.js in a next.js react project.
When I run or build i get this error "ReferenceError: AudioBuffer is not defined"
I have isolated the tone.js code in codesandbox and it's working perfectly.
https://codesandbox.io/s/tonejs-react-pink-noise-generator-pfnl0?file=/src/App.js
But not in the next.js app
ReferenceError: AudioBuffer is not defined
at ki (/node_modules/tone/build/Tone.js:1:117922)```
AudioBuffer is a web browser thing, it does not exist in node.js. The error you are getting is because the code that uses AudioBuffer can't run on the server. You need to instantiate that part of the code only in the browser. That is usually done in useEffect hook, or on the server, you can first check if window object is defined.
I am trying to add Cesium JS library to a React-Redux application and it keeps spitting out the error SyntaxError: Unexpected character '#'. I have tried multiple ways to do this and the same error occurs.
I am not sure why it is having an issue as the file the error is referring to was auto generated by npm install cesium. The problem file is node_modules\cesium\Source\Widgets\widgets.css. The CSS file contains a bunch of import CSS links that looks like #import url(./Viewer/Viewer.css);.
If anyone has any idea how to solve this error (commenting out that file just causes more errors) or maybe a method to add Cesium library to a React-Redux application that would be much appreciated.
Thanks
I am trying to use ngx-chips for tag-input, but I am having this issue with importing BrowserAnimationsModule.
On importing BrowserAnimationsModule, I get the error below:
An unhandled exception occurred while processing the request.
NodeInvocationException: document is not defined
ReferenceError: document is not defined
Once I comment BrowserAnimationsModule in import under app.module.shared.ts, my app works normal but once I uncomment it, I come up with the same error.
Please how can I trash this, I have been working on this for more than 4days.
Or suggest any other angular 4 tag-input library
I am using ASP.NET Core 2 SPA Template.
Thanks...
In your view's (Index.cshtml) app tag, replace the asp-prerender-module with asp-ng2-prerender-module.
I have no idea what to do here. Everything was working fine but all of a sudden when I deploy now I get cryptic errors

The code is working just fine locally. So I am lost. I don't even know where to begin debugging.
I am using iron router with useraccounts template package. I am not sure if it is related to that.
Ok I found out what the issue is.
When I defined a template helper like:
Template.notification.helpers
I misspelled notification
Which caused all the errors. But what is strange is that it worked locally but not when deployed.
Exceptions may be tolerated because they are in seperate files when working in development mode, however when deployed in production they're minified and join so the execution of the js file is stopped.

I am new to asp.net. I am learning SignalR, going through this tutorial. I have created everything correctly as mentioned in the tutorial. Now when I ran the Console Application, ERROR --> "One or more errors occurred." at hubConnection.Start().Wait();.(the console application is still running). Anyhow I tried even running the Web application which is not giving any error but the button broadcast doesnt do any action(I think it should). When I checked the code in Web application, I saw that one of the script source has green scribbles. Here is the Image.
Please explain what I am doing wrong..
Edit: I am using ASP.NET Development server.
Edit2: The errors I get in Google Chrome Console are:
Uncaught Error: SignalR: jQuery not found. Please ensure jQuery is referenced before the SignalR.js file. jquery.signalR-1.0.0-alpha2.min.js:10
Uncaught TypeError: Cannot read property 'signalR' of undefined hubs:17
Uncaught ReferenceError: $ is not defined
Answer: I just added reference of jQuery in my code above all the scripts and the "file not found" error is careless because it is running on server side.
The Link has also been updated with reference to jQuery
Just for anyone else who comes across this problem, I made the mistake of just copying the code from the tutorial and updating to the latest version of SignalR. The version had obviously changed and this needs to be updated in the script references i.e.
The jQuery src should be (depending on the version of signalR you have installed):
<script src="Scripts/jquery.signalR-1.1.3.js"></script>
The same thing would obviously apply to the standard jQuery library.
The error message describes fully what the problem is:
Uncaught Error: SignalR: jQuery not found. Please ensure jQuery is referenced before the SignalR.js file.
You need to include jQuery.
try "signalr/hubs" instead of "/signalr/hubs"
If the jQuery version is defined with npm with a *, e.g: "jquery": "*", in package.json and that version get's upgraded you might also see an issue very similar to this.
So downgrade the version of jQuery: "jquery": "2.2.4",
Today, I upgraded jQuery and SignalR to 2.2.0 and jQuery could not loading although I added jQuery before SignalR.
And, I downgraded jQuery as 2.1.4 system working well.
<script type="text/javascript" src="Scripts/jquery-2.1.4.js"></script>
<script type="text/javascript" src="Scripts/jquery.signalR-2.2.0.js"></script>
