ESLint in create-react-app - how to use it via VSCode?

Question

JavaScript

I'm learning react. Judging by the docs for create-react-app, it includes the config for eslint.
How to use this config via VSCode plugin?
If I don't manually install npm packages of eslint, cogfig and .eslintrc I get an error in VSCode:

[Info  - 12:21:21] ESLint server is running.
[Info  - 12:21:23] ESLint library loaded from: d:\React\test-project\node_modules\eslint\lib\api.js
[Warn  - 12:21:23] 
No ESLint configuration (e.g .eslintrc) found for file: d:\React\test-project\src\App.js
File will not be validated. Consider running 'eslint --init' in the workspace folder test-project
Alternatively you can disable ESLint by executing the 'Disable ESLint' command.

In the console after "npm start" or "yarn start" - eslint works correctly.

$ yarn start
yarn run v1.3.2
$ react-scripts start
Compiled with warnings.

./src/App.js
  Line 5:  'test' is assigned a value but never used  no-unused-vars

Add to package.json

"eslintConfig": {
    "extends": "react-app"
  }
