it's a weird issue I've got after I deployed my PWA application to prod (EKS). Some users and one of my brothers reported that they caught an issue which caused a white screen of death after refreshing and they had to refresh the page to use the application again. On my device, everything works just fine. I asked my brother about the error on the network tab in chrome's dev tools and these error lines showed up.
Uncaught SyntaxError: Unexpected token "<" 2.9345ebBe.chunk.js:1
Uncaught SyntaxError: Unexpected token "<" main.fa04b6.chunk.js:1
Any idea? I asked my brother about his chrome version, his device, his setup, the steps to reproduce but no luck. I read some topics on stackoverflow too. They said that maybe it's all about cache problem. The system tries to read a js file but it actually an HTML file the "<" token is the "<" from <!doctype html>. I asked my brother to clear all the caches but he still got the problem. I have no idea what's going on.

I just created my react-app and everything is working on my localhost also connecting to backend app through API which i configured, Now I just deployed my react app to nginx server after running yarn run build and i uploaded the build folder to my server root directory. The home page was serve and other page which needn't to connect to the server was serve as well but when I try to login I got an error and from the error I realised my app was sending request to http://localhost:3000/v1/auth/login instead of http://api.mysite.com/v1/auth/login How do I make this changes before building my react app. Below is my package.json file

Proxies only work for the dev server and don't work in production. You'll have to create an env file and use that instead. Here's how you'd do it:
// .env
REACT_APP_APP_HOST='https://api.mysite.com'
process.env.REACT_APP_APP_HOST // use this to access your api

Try to update your webpack configuration to handle loading svg files. inside the module.rules array you should add the following:
{
test: /\.(png|svg)$/,
use: ['file-loader']
}
I've developed UI using create-react-app. UI is working fine with the normal npm start command, but when I build the UI with npm run build it's throwing the error `Conversion from 'BigInt' to 'number' is not allowed

Error screenshot which is point in browser
My project was working correctly 100% until today when I started my development environment and it gave me a bunch of errors. The errors indicated my adding fallbacks for modules like HTTP and crypto. I did that and it gave me the error of Module fs not found.
I researched on the internet and downgraded my react-scripts from v5 to v4.0.3 and now when I start the project it gives me the following error
./node_modules/react-toastify/dist/react-toastify.esm.mjs
Can't import the named export 'cloneElement' from non EcmaScript module (only default export is available)
Error from chokidar (C:\node_modules): Error: EBUSY: resource busy or locked, lstat 'xxx:\DumpStack.log.tmp'

My app runs successfully but I am getting this error on browser console after using a few components of ant design.
When I installed the ant d I done these steps
npm install antd
added link tag of antd.compact.min.css to index.html
added script tag of /antd/4.13.1/antd.min.js to index.html
added script tag of /antd/4.13.1/antd-with-locales.min.js to index.html

I tried import React {Component} from "react"; and import * as React from 'react'; but not worked.
I found the solution for my problem. Firstly, if you are familiar with HTML CSS and JS structure and using UI libraries(antd ,bootstrap ,semantic UI) like I used to be, this problem could meet you to when you passed to frameworks like Reactjs.
Point is, no need to add CDN links <link> and <script> to your index.html file (if documentation does not says to add).
These steps are enough,(example for ant design UI library)
also this link Use in create-react-app says same
npm install antd
#import '~antd/dist/antd.css'; to App.css
and add import { Button } from 'antd'; to top of your component when using a ant design component such as button
Conclusion, this error occurs when add and tags to react app's index.html
