eslint-plugin-react | React specific linting rules for ESLint | Code Analyzer library

I am learning react js. I am a very beginner at this topic. But when I am doing setup to create a react environment I got an error. I have tried to solve the problem by Charles Stover blog in medium. But I got an error Command "up" not found.

Here's my index.js file:

Could you help me, I've got this error when I try building a project?

Oops! Something went wrong! :(

ESLint: 8.0.0

TypeError: Failed to load plugin '@typescript-eslint' declared in 'src.eslintrc': Class extends value undefined is not a constructor or null Referenced from: src.eslintrc

package.json

I've been asked to go through our application and update all the frameworks as it was incredibly outdated, one of the things was to update babel, now one of our scripts in package.json was:

How does one format props and typescript definitions alphabetically on save? Ideally it is some configuration for the whole project as opposed to a VSCode plugin (though I'm open a plugin too at this point).

I am currently setting up a boilerplate with React, Typescript, styled components, webpack etc. and I am getting an error when trying to run eslint:

Error: Must use import to load ES Module

Here is a more verbose version of the error:

For a simple project, when running npm install and npm start, my default web browser¹ opens, and I hit F12 to see two types of error messages in the console.

As you can see, the error messages are:

• Uncaught ReferenceError: process is not defined, and
• Line 0: Parsing error: ImportDeclaration should appear when the mode is ES6 and in the module context.

What should I do to rectify these errors?

I believe these errors are related to ReactJS, which under the hood uses Webpack.

I have seen these errors elsewhere, sometimes with a reference to version issues for ReactJS and/or Webpack. For more examples, see the list of references below. Some of those links (questions) might be related to the issues here, but I am not sure.

I provide my .eslintrc.json and package.json files below. But since they will hardly be sufficient to reproduce the error, here is a link to a zip file containing all the necessary project files. ²

After upgrading my webpack from v4 to v5, I got this error that is getting me a hard time debugging.

I'm currently creating a new React application with create-react-app. After that I install eslint that extends plugin:react/recommended and google. 2 weeks ago I did the same and I had no problems but since 2 days I now get a "Missing "key" prop for element in array" error in my index.tsx and App.tsx files for each html line.

After upgrading react-scripts to v5, craco start does not work properly. App starts with no error but in browser, there is a blank page and if i open inspector, i only see index.html codes not react codes. It was working well with react-scripts@4.0.3. Here is my local files;
