v3xlabs ESLint Presets

The official v3xlabs JavaScript and TypeScript lint presets.

This package targets ESLint v10 flat config only. To use these rules you must be on the latest ESLint (v10) or newer.

Quick setup

Create command

The create-eslint-v3xlabs utility sets up linting in an existing or new project.

It will:

• detect your package manager
• install required dev dependencies
• generate eslint.config.mjs
• generate or update .prettierrc
• add a lint script

Use one of:

bun create eslint-v3xlabs
pnpm create eslint-v3xlabs
yarn create eslint-v3xlabs
npm create eslint-v3xlabs

Installation

pnpm add -D eslint eslint-plugin-v3xlabs

Usage (ESLint v10)

Create eslint.config.mjs:

import v3xlabs from 'eslint-plugin-v3xlabs';

export default [...v3xlabs.configs['flat/recommended']];

Recommended package.json script:

{
    "scripts": {
        "lint": "eslint ."
    }
}

Opinionated defaults

The preset is intentionally strict and formatting-heavy. It enforces:

• import sorting
• unused import removal
• descriptive identifiers (discourages generic id)
• structured empty lines and line breaks
• modern JavaScript and TypeScript rules
• quality gates with SonarJS and Unicorn

AI skill package

An installable agent skill for this preset lives at skills/v3xlabs-eslint/SKILL.md.

It captures:

• ESLint v10 setup flow
• v3xlabs architecture and TypeScript conventions
• naming and formatting expectations for aggressive linting environments
