.eslintrc.js for React 17 and JSX without import 'react'


in react 17 is not necessarily use

import React from 'react';

but if i don't have it, so eslint gave me error

'React' must be in scope when using JSX react/react-in-jsx-scope

any idea how modify .eslintrc.js

module.exports = {
  parser: "babel-eslint",
  env: {
    browser: true,
    node: true,
    es6: true,
    jest: true,
  },
  extends: [
    "eslint:recommended",
    "plugin:react/recommended",
    "plugin:jsx-a11y/recommended"
    ],
  plugins: [
    "react",
    "react-hooks",
    "jsx-a11y",
  ],
  rules: {
    strict: 0,
    "react-hooks/rules-of-hooks": "error",
    "react-hooks/exhaustive-deps": "warn"
  },
  settings: {
    react: {
      version: "detect"
    }
  }
}

for react 17?

Thank's a lot


Solution

  • You can read about it in React docs.

    If you are using eslint-plugin-react, the react/jsx-uses-react and react/react-in-jsx-scope rules are no longer necessary and can be turned off or removed.

    {
      // ...
      "rules": {
        // ...
        "react/jsx-uses-react": "off",
        "react/react-in-jsx-scope": "off"
      }
    }
    

    To make it work, you should add those rules to your eslint config, see Extending or replacing the default ESLint config for Create-React-App specifics, every framework should have related section in their docs.
