How do I set up React-spring in codepen? - reactjs

I tried to create a basic setup to start practicing react-spring in CodePen, but it shows an error: Uncaught ReferenceError: require is not defined. I don't know why this happens and how to fix it.
This is the code of my app so far (as you can seee, it's super short):

Thanks in advance!

Codesandbox maybe an easier option.
Here is an example:

Error: Property left of ForInStatement is null?

yesterday I was able to create my react babylon app with react-scripts. After updating babylon to 4.1.0 I receive the following error:
./node_modules/babylonjs/babylon.js TypeError:
/git/proconf_sa/node_modules/babylonjs/babylon.js: Property left of ForInStatement expected node to be of a type [“VariableDeclaration”,“LVal”] but instead got null
Any idea what the problem could be? I updated from version 3.1.0-alpha3.7.
Thanks.
I was facing the same problem, however using Angular. I resolved by removing a package that uses svg.js#2.7.1 !!! From what you discover, this error is caused by the discontinued version of svg.js#2.7.1 !!! Look inside your application that there is a package using this and remove it!
If using apexcharts update it, because it depends on svg.js!

How to handle error while running react application with the following error message?

Any suggestions on how to solve this?
Seeing at the error, I guess you forgot to add the specific loader in webpack to make the JS compiler understand your converted css.
One more suggestion is to add ErrorBoundaries to your components to understand whether this error is at component level or at bootstrap time.

Can't resolve 'Math/Long'./node_modules/bytebuffer/ByteBuffer.js Module not found: Can't resolve 'Math/Long'

Hey all I'm trying to access the MTA's api in react using import GtfsRealtimeBindings from 'mta-gtfs-realtime-bindings'
yet i just keep getting this same error Can't resolve 'Math/Long'./node_modules/bytebuffer/ByteBuffer.js Module not found: Can't resolve 'Math/Long'
The more i read about it , seems like I might have an issue with webpack? I'm curious if anyone has ran into a similar issue before hand. Any help would be greatly appreciated. Thank you
I had the same exact problem.
The way I "fix" this is go to ./node_modules/bytebuffer/ByteBuffer.js and change "Math/Long" to "long" under the AMD loading all the way in the button of the file.
Do the same if you have another similar problem where it can't find ByteBuffer in ProtoBuf.js-- change "ByteBuffer" to "bytebuffer".
This is not a permanent fix, as it will reset itself when npm update/install is executed.

Uncaught ReferenceError: require is not defined at typeahead.js:2

I am getting following Error as I used Ui.bootstrap's typeahead library
Uncaught ReferenceError: require is not defined
at typeahead.js:2
Tried googling for this but nothing helpful found,Any help will be appreciated
Thanks in advance
Require doesn't work in browser.Basically require is a node_module by which we can access other modules or files.So please if you are using it on browser side then try other things like import or self.import.
Please refer this stack question and answer by Latheesan
Please also check require.js as well.
require.js

Angular Routing - Error: [ng:areq]

I'm trying to build an application with Angular but I've run into an error that I'm unsure how to resolve. It seems to have something to do with the routing that I have set up.
As soon as the page loads it is forced by the routing to go to the first view, which is what I want it to do, but it is throwing a weird error...
Error: [ng:areq] http://errors.angularjs.org/1.2.19/ng/areq?p0=LoginController&p1=not%20aNaNunction%2C%20got%20undefined
at Error (native)
The best way I could get your hands on my code is to load it into GitHub. You can find my repository here...

It's pretty simple and strait forward so far. Not a lot of code to dig through yet. Can anybody see what I'm doing wrong?
Thanks
Well, that's pretty embarrassing. As miqid mentioned in the comment, I had forgotten to include script tag references to my controller files.
