Frequently Asked Questions

Which preset per project?

React (JSX + hooks rules), Node (server globals, no browser APIs), TypeScript (type-aware rules needing project references). Mixed repos layer presets.

Flat config or eslintrc?

Flat config (eslint.config.js) — the current standard ESLint 9+ expects. Legacy .eslintrc still works but earns deprecation warnings.

Rules strictness?

Recommended sets catch bugs without style wars; strict adds stylistic opinions. Start recommended, tighten per team pain.

Do config files upload anywhere?

No — generation runs locally in your browser. Nothing leaves your device.
