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 ment 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();
This is the package.json file

Did you change what
index.jsimports as well? Really both of them should be renamed. – zero298 Commented Dec 17, 2019 at 21:05 - No I haven't done any changes with index.js file – user10728848 Commented Dec 17, 2019 at 21:06

Does it say
import {} from "./App.js"orimport {} from "./App.tsx"or maybe evenimport {} from "./App"? – zero298 Commented Dec 17, 2019 at 21:06 - I added the index.js code. – user10728848 Commented Dec 17, 2019 at 21:09
- Any package.json code? – keikai Commented Dec 17, 2019 at 21:12

Reset to default 4You may just need to install related type libs.
npm install --save @types/react @types/react-dom
Try it out.
