I've created a react project with the instructions from it's documentation, which automatically has added the App.js file to the project. My issue is that I want to use App.tsx instead of App.js. For some reason, I am not able to run App.tsx file. How can I fix this, please?
I have read this question asked here, but I couldn't use it as it didn't make any sense to me since this is my first project with react.
This is my folder structure.
It can be seen on this image, I get an error on the browser when I comment it out the App.js file.
This is the index.js file, which is not changed.
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import * as serviceWorker from './serviceWorker';
ReactDOM.render(<App />, document.getElementById('root'));
serviceWorker.unregister();

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
i dont know why it is issue occured

In my opinion, several CSS libraries are overlapping to create an issue
so now I'm removing them one by one
but i got still problem
i'm sorry about not good at english
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)

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
I am using material UI in my react application and I am having difficulty getting the material-ui-pickers example to work.

I have installed date-fns but i still get the error.
https://www.npmjs.com/package/date-fns.
I also deleted all the node module and did a npm install to see if that would solve the issue but it did not.
Thanks for the help.
install this(see here):
npm i --save date-fns#next #date-io/date-fns
Try using date-fns 2.0.0. I had the same issue and fixed by updating the lib. Hope it works.
