Step 1. Instantiate the Node Package Manager

Run cmd : npm init

It will ask you to create the package.json.

Step 2. Set up the eslint

Run cmd : npx eslint --init

It will ask you to create .eslintrc & initiate files.

Step 3. Add the prettier

Run cmd : npm i -D prettier eslint-config-prettier eslint-plugin-prettier

"eslint-config-prettier", "eslint-plugin-prettier" is for the preventing conflict

And then, add the "plugin:prettier/recommended" to the .eslintrc's extends key as an array

Also, add prettier config to the .eslintrc's rules key.

"rules : {
    // ...etc
    "prettier/prettier": [
        "error",
        {
            "trailingComma": "es5",
            "singleQuote": true,
            "printWidth": 100,
            "semi": true
        }
    ]

}

Step 4. Create the index.js file

Export the index.js

Step 5. Declare peerDependencies

As it is stated in the official ESLint docs, you should declare your dependency on ESLint in package.json using the peerDependencies field. So just copy all dev dependencies in the package.json file to peerDependencies field:

// package.json

...

"peerDependencies": {
    "@typescript-eslint/eslint-plugin": "^5.5.0",
    "@typescript-eslint/parser": "^5.5.0",
    "eslint": "^8.4.0",
    "eslint-config-prettier": "^8.3.0",
    "eslint-plugin-prettier": "^4.0.0",
    "eslint-plugin-react": "^7.27.1",
    "eslint-plugin-react-hooks": "^4.3.0",
    "eslint-plugin-simple-import-sort": "^7.0.0",
    "prettier": "^2.5.1"
  }

Step 6. Add airbnb style

Run cmd : yarn add -D eslint-config-airbnb

And then, add the "airbnb" to the extends

module.exports = {
  ...etc,
  extends: ["plugin:react/recommended", "airbnb", "plugin:prettier/recommended"],
  ...
};
