eslint-plugin-typefest

ESLint plugin for teams that want consistent TypeScript-first conventions based on:

• type-fest
• ts-extras

The plugin ships focused rule sets for modern Flat Config usage, with parser setup included in each preset.

Installation

npm install --save-dev eslint-plugin-typefest typescript

@typescript-eslint/parser is loaded automatically by plugin presets.

Quick start (Flat Config)

import typefest from "eslint-plugin-typefest";

export default [typefest.configs.recommended];

That is enough for TypeScript files (**/*.{ts,tsx,mts,cts}).
