@shiron-dev/eslint-config v2.1.1

@shiron-dev/eslint-config

Thanks to @antfu/eslint-config, the source of this eslint-config customization!

Usage

Starter Wizard

We provided a CLI tool to help you set up your project, or migrate from the legacy config to the new flat config with one command.

pnpm dlx @shiron-dev/eslint-config@latest

Manual Install

If you prefer to set up manually:

pnpm i -D eslint @shiron-dev/eslint-config

And create eslint.config.mjs in your project root:

// eslint.config.mjs
import shiron from "@shiron-dev/eslint-config";

export default shiron();

If you still use some configs from the legacy eslintrc format, you can use the @eslint/eslintrc package to convert them to the flat config.

import { FlatCompat } from "@eslint/eslintrc";
// eslint.config.mjs
import shiron from "@shiron-dev/eslint-config";

const compat = new FlatCompat();

export default shiron(
  {
    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"
  }
}

IDE Support (auto fix on save)

Install VS Code ESLint extension

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

{
  // 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", "fixable": true },
    { "rule": "format/*", "severity": "off", "fixable": true },
    { "rule": "*-indent", "severity": "off", "fixable": true },
    { "rule": "*-spacing", "severity": "off", "fixable": true },

    { "rule": "*quotes", "severity": "off", "fixable": true },
    { "rule": "*semi", "severity": "off", "fixable": true }
  ],
