My ESLint config for Javascript, Typescript, React and Node 🚀

I use the ESLint extension on Visual Studio code in my day-to day coding activities. I find ESLint to be of a great help to write some proper, clean-cut ES6 code, avoid errors and enforce best practices. Here is the configuration I use to lint my *.js, *.ts, *.jsx and *.tsx files, available as a shareable config.

How I use ESLint in my dev environment

• Windows 10 x64, Hyper-V enabled.
• Debian Bookworm running in a Hyper-V VM.
• Node.js v22.15.0 LTS on Debian.
• VSCode targeting Debian through SSH.
• VSCode ESLint extension enabled.
• ESLint v9.29.0 installed as a project dev dependency.
• @mulekick/eslint-config-muleslint installed as a project dev dependency.
• A minimal eslint.config.js file included in the project's root folder :

/* eslint-disable import/no-unresolved */
import muleslint from "@mulekick/eslint-config-muleslint";
import {defineConfig} from 'eslint/config';

// .eslintignore doesn't work with flat configs
export default defineConfig(...muleslint, {
    ignores: [ `**/node_modules/**`, `**/dist/**`, `**/build/**` ]
});

Use it in your own project

• Install with npx install-peerdeps --dev @mulekick/eslint-config-muleslint.
• Be sure to add the above eslint.config.js file in your project's root folder.

Configuration details

• This configuration uses the new eslint flat config format.
• It extends the following configurations :

configuration	description
eslint.configs.recommended	core eslint recommended configuration
stylistic.configs.recommended	recommended configuration for stylistic-related eslint rules
typescript.configs.strictTypeChecked	typescript-eslint strict configuration with type-checked linting enabled 🤖
import.flatConfigs.recommended	recommended configuration from the eslint import plugin
n.configs['flat/recommended']	recommended configuration from the eslint node plugin
react.configs.flat.recommended	recommended configuration from the eslint react plugin
security.configs.recommended	recommended configuration from the eslint security plugin

• It also uses the html plugin to lint JS code in HTML pages <script> tags.
• Quite a few of the eslint.configs.recommended and stylistic.configs.recommended options are overriden 😁
• The use of modern ECMA features (ES6 and beyond) is enforced whenever possible.
• The use of Crockford indentation (4 spaces) and unix-style line breaks is enforced as well.
• ESM modules use is enforced too, therefore making strict mode mandatory everywhere 👍
