I want to display a Material UI list as part of my drop down menu (a Material UI drawer component) for mobile view but for some reason the actual list doesn't get displayed.
The code for the list looks like this:
const menuItems = [
{
text: 'Home',
path: '/'
},
{
text: 'About',
path: '/about'
}
];
...
<List>
{menuItems.map(item => (
<ListItem
button
key={item.text}
onClick={() => history.push(item.path)}
>
<ListItemText>{item.text}</ListItemText>
</ListItem>
))}
</List>
This is the result where my list items should be displayed but instead I get this strange icon:
Here is my package.json file:
{

}
}

EDIT:
Here is a working CodeSandbox example
The error is in the import.
Correct:
import List from "#material-ui/core/List";
You imported List from "#material-ui/icons/List". You should remove it and import List from "#material-ui/core":
import { List } from "#material-ui/core";

I have a react app , I packaged it using npm pack and I want to use it inside the main.ts in an electron app ,
I'm trying to import it like this import App from 'mypackage' but it keeps giving me this error
Error [ERR_REQUIRE_ESM]: require() of ES Module C:\node_modules\mypackage\src\index.js from C:\src\main\main.ts not supported.
Instead change the require of index.js in C:\src\main\main.ts to a dynamic import() which is available in all CommonJS modules.
in my json file

I add in my package.json proxy for making request to server runing on other port.
after that, my module css styles stop working, in the devTools i found that the styles are loading well, but classnames for DOM elements are not loading at all.
How it looks now:
How it should be:
some page code:
import styles from "./LoginPage.module.css";
export default function LoginPage() {
return (
<div className={styles.LoginPage}>
</div>
);
}
Here is my package.json:

}
your filename is incorrect. for css modules you don't need to add .module to the filename, just name it LoginPage.css and import it with that same name and your styles should be fine. React is getting confused with your module filename.
I created a react project with create-react-app some times ago and i wanted to add some test with jest. I read that Jest comes with create-react-app, but when i try to run the simple test that comes with the project by typing "yarn test", i have this error message: TypeError: (0 , _react2.test) is not a function
The test:
import React from 'react';
import { render, screen, expect, test} from '#testing-library/react';
import App from './App';
test('renders learn react link', () => {
render(<App />);
const linkElement = screen.getByText(/learn react/i);
expect(linkElement).toBeInTheDocument();
});
The result:

delete your node_modules folder from the project and run this command npm install then run your project
