ESLint-Config-Removify

• ESLint-Config-Removify
• Install
• Create config file
• Add script for package.json
• VS Code support (auto fix)
• View what rules are enabled
• Formatters

This is a flat config for ESLint that we use in our projects, this is a fork of @antfu/eslint-config that fits our demands better.

Install

pnpm i -D eslint eslint-config-removify

Create config file

With "type": "module" in package.json (recommended):

// eslint.config.js
import removify from 'eslint-config-removify';

export default removify();

With CJS:

// eslint.config.js
const removify = require('eslint-config-removify').default;

module.exports = removify();

!TIP ESLint only detects eslint.config.js as the flat config entry, meaning you need to put type: module in your package.json or you have to use CJS in eslint.config.js. If you want explicit extension like .mjs or .cjs, or even eslint.config.ts, you can install eslint-ts-patch to fix it.

Combined with legacy config:

// eslint.config.js
const removify = require('eslint-config-removify').default;
const { FlatCompat } = require('@eslint/eslintrc');

const compat = new FlatCompat();

module.exports = removify(
  {
    ignores: [],
  },

  // Legacy config
  ...compat.config({
    extends: [
      'eslint:recommended',
      // Other extends...
    ],
  })

  // Other flat configs...
);

Note that .eslintignore no longer works in Flat config, see customization for more details.

Add script for package.json

For example:

{
  "scripts": {
    "lint": "eslint .",
    "lint:fix": "eslint . --fix"
  }
}

VS Code support (auto fix)

Install VS Code ESLint extension

Add the following settings to your .vscode/settings.json:

{
  // Enable the ESlint flat config support
  "eslint.experimental.useFlatConfig": true,

  // Disable the default formatter, use eslint instead
  "prettier.enable": false,
  "editor.formatOnSave": false,

  // Auto fix
  "editor.codeActionsOnSave": {
    "source.fixAll.eslint": "explicit",
    "source.organizeImports": "never"
  },

  // Silent the stylistic rules in you IDE, but still auto fix them
  "eslint.rules.customizations": [
    { "rule": "style/*", "severity": "off" },
    { "rule": "format/*", "severity": "off" },
    { "rule": "*-indent", "severity": "off" },
    { "rule": "*-spacing", "severity": "off" },
    { "rule": "*-spaces", "severity": "off" },
    { "rule": "*-order", "severity": "off" },
    { "rule": "*-dangle", "severity": "off" },
    { "rule": "*-newline", "severity": "off" },
    { "rule": "*quotes", "severity": "off" },
    { "rule": "*semi", "severity": "off" }
  ],

  // Enable eslint for all supported languages
  "eslint.validate": [
    "javascript",
    "javascriptreact",
    "typescript",
    "typescriptreact",
    "vue",
    "html",
    "markdown",
    "json",
    "jsonc",
    "yaml",
    "toml"
  ]
}

View what rules are enabled

I built a visual tool to help you view what rules are enabled in your project and apply them to what files, eslint-flat-config-viewer

Go to your project root that contains eslint.config.js and run:

npx eslint-flat-config-viewer

Formatters

!WARNING Experimental feature, changes might not follow semver.

Use external formatters to format files that ESLint cannot handle yet (.css, .html, etc). Powered by eslint-plugin-format.

// eslint.config.js
import removify from 'eslint-config-removify';

export default removify({
  formatters: {
    /**
     * Format CSS, LESS, SCSS files, also the `<style>` blocks in Vue
     * By default uses Prettier
     */
    css: true,
    /**
     * Format HTML files
     * By default uses Prettier
     */
    html: true,
    /**
     * Format Markdown files
     * Supports Prettier and dprint
     * By default uses Prettier
     */
    markdown: 'prettier'
  }
});
