eslint-config-gen

ESLint Config Generator

Every team argues about eslint rules. This tool reads your actual code and generates a config that matches how you already write.

One command. Zero config. Just works.

Quick Start

npx ai-eslint-config

What It Does

• Analyzes your existing code style
• Generates ESLint config matching those patterns
• Supports flat config and legacy formats
• No more arguing about semicolons

Usage Examples

# Generate eslint.config.js
npx ai-eslint-config

# Legacy .eslintrc.json format
npx ai-eslint-config --format json

# Analyze specific directory
npx ai-eslint-config --dir ./src

Best Practices

• Run on representative code - not just one file
• Review the rules - might catch some bad habits too
• Add prettier if needed - don't mix formatting with linting
• Commit the config - everyone uses the same rules

When to Use This

• Starting a new project and need eslint setup
• Inheriting a project with no linting
• Want to codify existing code style
• Migrating to flat config format

How It Works

Reads sample files from your codebase, identifies patterns like semicolon usage, quote style, and indentation. Then generates an ESLint config that enforces those patterns.
