How to connect ESLint to a project?

Question

webstorm

I'm trying to connect ESLint to a React project. Created a config (eslintrc.js):

module.exports = {
  env: {
    browser: true,
    es2020: true,
    node: true,
    jest: true,
  },
  extends: [
    'plugin:react/recommended',
    'airbnb',
  ],
  settings: {
    'import/resolver': {
      node: {
        paths: ['src'],
      },
    },
  },
  parser: '@typescript-eslint/parser',
  parserOptions: {
    ecmaFeatures: {
      jsx: true,
    },
    ecmaVersion: 11,
    sourceType: 'module',
  },
  plugins: [
    'react',
    '@typescript-eslint',
  ],
  rules: {
    'react/prop-types': 'off',
    indent: [2, 'tab'],
    'react/jsx-indent': [2, 'tab'],
    'react/jsx-indent-props': [2, 'tab'],
    'no-tabs': 'off',
    'import/no-unresolved': 'warn',
    'object-curly-spacing': 'off',
    'react/jsx-filename-extension': [1, {extensions: ['.js', '.jsx']}],
  },
};

But an error occurs

Error: Plugin "react" was conflicted between ".eslintrc.js" and "../.eslintrc".

Interestingly, everything works in VSCode, but not in WebStorm

Answer 1

Should be obvious from the error message, no? Above in the root of the project you have another file .eslintrcthat somehow conflicts with yours.
