Configurations

This repository contains opinionated configurations for some tooling of the javascript ecosystem.

ESLint

To use the minimal configuration, create or update the eslint.config.js file in your project with the following content:

import { defineConfig } from '@ecohead/configs/eslint';

export default defineConfig({
	// Your additional configuration here
});

The defineConfig function also accepts as a second argument an array of files to be ignored by eslint in your project.

Built-in configurations

I provide some built-in configurations that you can use directly in your project, based on my personal preferences. I have disabled some rules that I find too strict or not useful for my use case. You are free to use them all or only some of them.

If you want to include all of them, I export a special variable that contains all the configurations.

import { defineConfig, all } from '@ecohead/configs/eslint';

export default defineConfig([...all]);

@eslint/js

import { defineConfig, native } from '@ecohead/configs/eslint';

export default defineConfig([...native]);

typescript-eslint

import { defineConfig, typescript } from '@ecohead/configs/eslint';

export default defineConfig([...typescript]);

eslint-plugin-unicorn

import { defineConfig, unicorn } from '@ecohead/configs/eslint';

export default defineConfig([...unicorn]);

eslint-plugin-sonarjs

import { defineConfig, sonar } from '@ecohead/configs/eslint';

export default defineConfig([...sonar]);

@eslint-community/eslint-plugin-eslint-comments

import { defineConfig, comments } from '@ecohead/configs/eslint';

export default defineConfig([...comments]);

eslint-plugin-n

import { defineConfig, node } from '@ecohead/configs/eslint';

export default defineConfig([...node]);

eslint-config-prettier

import { defineConfig, prettier } from '@ecohead/configs/eslint';

export default defineConfig([...prettier]);

eslint-plugin-no-use-extend-native

import { defineConfig, noUseExtendNative } from '@ecohead/configs/eslint';

export default defineConfig([...noUseExtendNative]);

eslint-plugin-promise

import { defineConfig, promise } from '@ecohead/configs/eslint';

export default defineConfig([...promise]);

eslint-plugin-import-x

import { defineConfig, importX } from '@ecohead/configs/eslint';

export default defineConfig([...importX]);

eslint-plugin-tailwindcss

import { defineConfig, tailwindcss } from '@ecohead/configs/eslint';

export default defineConfig([...tailwindcss]);

@adonisjs/eslint-plugin

import { defineConfig, adonis } from '@ecohead/configs/eslint';

export default defineConfig([...adonis]);

@unocss/eslint-config

import { defineConfig, unocss } from '@ecohead/configs/eslint';

export default defineConfig([...unocss]);

Prettier

The configuration is based mainly for accessibility and readability purposes, which for some part is inherited from this reddit post.

Usage

To use the configuration, you can add the following to your prettier.config.js file:

import { definePrettierConfig } from '@ecohead/configs/prettier';

export default definePrettierConfig({
	// Your additional configuration here
});

Built-in plugins

prettier-plugin-packagejson

Plugin documentation

This plugin formats the package.json file in a more readable way, using sort-package-json under the hood.

Add any prettier plugin

To add a plugin in your configuration, simply add it to the plugins array in the definedPrettierConfig function after installing it.

The following example shows how to add the prettier-plugin-tailwindcss plugin:

import { definePrettierConfig } from '@ecohead/configs/prettier';

export default definePrettierConfig({
	// Your additional configuration here
	plugins: [
		// ...
		'prettier-plugin-tailwindcss',
	],
	tailwindFunctions: ['clsx', 'cx', 'cva', 'cw', 'twMerge', 'tw'],
});

Stylelint

I export two configurations :

• One for CSS files
• One for SCSS files

The SCSS configuration is based on the CSS configuration, with some additional rules for SCSS files.

Usage

To use the configuration, you can add the following to your stylelint.config.js file:

import { css, scss } from '@ecohead/configs/stylelint';

/** @type {import('stylelint').Config} */
export default {
	...css, // or ...scss
	// Your additional configuration here
};

Typescript

The TypeScript configuration is as strict as possible from my point of view. It is inherited in high parts from the astro team's configuration.

I also export a special tsconfig file dedicated to eslint, which enables the noEmit flag.

Usage

To use the configuration, you can add the following to your tsconfig.json file:

For the default configuration:

{
	"extends": "@ecohead/configs/tsconfig.json",
	"compilerOptions": {
		// Your additional configuration here
	}
}

For the eslint configuration:

{
	"extends": "@ecohead/configs/tsconfig.eslint.json",
	"compilerOptions": {
		// Your additional configuration here
	}
}
