ESLint Rule Analyzer

Analyzes ESLint configurations using the ESLint Node.js API (new ESLint().calculateConfigForFile) and flat config system. Detects rule conflicts, unused rules, and generates project-specific rule recommendations from eslint-plugin-unicorn and typescript-eslint.

Installation

Use the upstream install or setup path that matches your environment:

• npm init @eslint/config@latest
• npx eslint yourfile.js

Requirements and caveats from upstream:

• To use ESLint, you must have Node.js (^20.19.0, ^22.13.0, or >=24) installed and built with SSL support. (If you are using an official Node.js distribution, SSL is always built in.)
• node-linker=hoisted

• Which Node.js versions does ESLint support?

Basic usage or getting-started notes:

• Installation and Usage

• If you use ESLint's TypeScript type definitions, TypeScript 5.3 or later is required.
