How to configure eslint and prettier with nuxt 3?

Question

I have installed these dependencies Package.json:

    {

      "devDependencies": {
        "@intlify/nuxt3": "^0.1.6",
        "@nuxtjs/eslint-config": "^7.0.0",
        "@nuxtjs/eslint-module": "^3.0.2",
        "eslint": "^8.1.0",
        "eslint-config-prettier": "^8.3.0",
        "eslint-plugin-nuxt": "^3.0.0",
        "eslint-plugin-vue": "^7.20.0",
        "nuxt3": "latest",
        "prettier": "2.4.1",
        "sass": "^1.43.3",
        "vite-plugin-eslint": "^1.3.0"
      }
    }

At.eslintrc.js

  extends: [
    'eslint:recommended',
    'plugin:nuxt/recommended',
    'prettier'
  ],

At nuxt.config.ts

import eslintPlugin from 'vite-plugin-eslint';
export default defineNuxtConfig({
...
    vite: {
        plugins: [eslintPlugin()]
    },
    buildModules: ['@intlify/nuxt3', '@nuxtjs/eslint-module',],
})

And none of these options are working with nuxt 3.

Answer 1

A simple ESLint + Prettier + TypeScript + Nuxt 3 (or Bridge) setup would look like this:

yarn add --dev eslint prettier eslint-config-prettier eslint-plugin-prettier @nuxtjs/eslint-config-typescript

.eslintrc.js

module.exports = {
  root: true,
  extends: ['@nuxtjs/eslint-config-typescript', 'plugin:prettier/recommended'],
}

package.json

{
  "scripts": {
    "lint": "eslint --ext .ts,.js,.vue ."
  }
}

Here's a config i found here: https://github.com/nuxt/framework/discussions/2815#discussioncomment-2050408

// .eslintrc.json
{
  "env": {
    "browser": true,
    "es2021": true,
    "node": true
  },
  "extends": [
    "eslint:recommended",
    "plugin:vue/vue3-recommended",
    "plugin:@typescript-eslint/recommended",
    "@nuxtjs/eslint-config-typescript"
  ],
  "parserOptions": {
    "ecmaVersion": "latest",
    "parser": "@typescript-eslint/parser",
    "sourceType": "module"
  },
  "plugins": [
    "vue",
    "@typescript-eslint"
  ],
  "rules": {}
}

If you really want to use prettier (imo eslint already does the job, using both can be very annoying to configure) you could add eslint-plugin-prettier library, then add "plugin:prettier/recommended" to eslint extends.

Idk what IDE you're using but if it's vscode, I advise you to use the linting on save instead of relying on formatters (Volar, prettier, eslint-prettier). Mostly because it forces all devs to have the same format and rules
