It's a duplicate question on SVG, but maybe my scenario is different, I am not able to understand any solution on the web for my problem which is, getting below error

Thanks in advance!

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']
}

Error: Conversion from 'BigInt' to 'number' is not allowed on react build script

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
I didn't get many related solutions to my problem on google. Can someone help please ?

Error screenshot which is point in browser

I deployed react to vercel, but only a blank screen appears

I used react as frontend and firebase as backend.
And it succeeded in deploying to vercel.
But it just shows a blank screen.
And when I go to the console, this error code appears.

import my local react package in an electron app

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.

React app: Jest encountered an unexpected token

I try to test my app created via create-react-app. There is only one test file generated automatically:
import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
it('renders without crashing', () => {
const div = document.createElement('div');
ReactDOM.render(<App />, div);
ReactDOM.unmountComponentAtNode(div);
});
This is my package.json (also i have package-lock.json (~ 15k rows)):
{
"name": "project",
"version": "0.1.0",
"private": true,
"dependencies": {
"avro-js": "^1.9.1",

}
}
When i try to test it using test script i get this error:
Jest encountered an unexpected token
This usually means that you are trying to import a file which Jest cannot parse, e.g. it's not plain JavaScript.
By default, if Jest sees a Babel config, it will use that to transform your files, ignoring "node_modules".
Details:
({"Object.<anonymous>":function(module,exports,require,__dirname,__filename,global,jest){export
{ default as a11yDark } from './a11y-dark';
Also, i don't have .babelrc file. I tried to add .babelrc but it didn't help (or maybe i did it incorrectly)

If you are getting this error when trying to import the javascript styles for the component, make sure you are targetting the
react-syntax-highlighter/dist/cjs/...
instead of the
react-syntax-highlighter/dist/esm/...
Jest should be able to parse that.

So, finally i've solved this.
My final configs are:
babel.config.js:
module.exports = {
presets: ['#babel/preset-env', '#babel/preset-react'],
};
package.json:
{
"name": "project",
"version": "1.0",
"private": true,
"dependencies": {

"reactstrap": "^8.0.1",
"redux": "^4.0.4",
"redux-thunk": "^2.3.0"
},
"jest": {
"transformIgnorePatterns": [
"/node_modules/(?!(react-syntax-highlighter)/)"
]
},
"devDependencies": {
"#babel/cli": "^7.0.0",
"#babel/core": "^7.0.0",
"#babel/preset-env": "^7.0.0",
"#babel/preset-react": "^7.0.0",
"babel-core": "^7.0.0-bridge.0",
"babel-eslint": "^10.0.3",

"babel-loader": "^8.0.0",
"enzyme": "^3.10.0",
"enzyme-adapter-react-16": "^1.15.1",
"eslint": "^6.7.1",
"jest": "^24.9.0",
"jest-cli": "^24.9.0",
"react-test-renderer": "^16.12.0",
"redux-mock-store": "^1.5.3"
},
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test",
"eject": "react-scripts eject"
},
"eslintConfig": {
"extends": "react-app"

"browserslist": {

"not dead",
"not op_mini all"
],
"development": [
"last 1 chrome version",
"last 1 firefox version",
"last 1 safari version"
]
}
}
I'm not sure that this is the best solution, but at least it works
