description	Generate ESLint config from your codebase patterns. Use when setting up linting.

ESLint Config Generator

Stop copying ESLint configs from other projects. This tool scans your actual codebase and generates a config that matches how you already write code.

One command. Zero config. Just works.

Quick Start

npx ai-eslint-config .

What It Does

• Scans your existing code to detect patterns and conventions
• Generates .eslintrc that matches your actual style
• Handles TypeScript, React, Vue, and Node.js projects
• Sets up proper parser and plugin configurations
• Avoids rules that would flag your existing code

Usage Examples

# Analyze and generate for current project
npx ai-eslint-config .

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

# Output to specific file
npx ai-eslint-config . -o .eslintrc.json

Best Practices

• Run on clean code first - Generate config after your codebase is in a good state
• Review the rules - AI picks sensible defaults but you know your team's preferences
• Extend don't override - Use extends for shared configs, customize only what you need
• Add incrementally - Start lenient, tighten rules over time

When to Use This

• Starting a new project and need linting fast
• Standardizing code style across a team
• Migrating from TSLint or other deprecated linters
• Learning ESLint rules through real examples

How It Works

The tool uses glob patterns to find source files, analyzes code style patterns like semicolons, quotes, and spacing, then generates an ESLint config that codifies those patterns into enforceable rules.
