@larvit/eslint-config-typescript-esm

Shareable flat config for ESLint 9+ targeting TypeScript ESM projects. Builds on @larvit/eslint-config-esm and adds typescript-eslint, TS-aware @stylistic formatting and perfectionist interface/type/enum sorting.

Installation

npm install --save-dev eslint typescript globals @larvit/eslint-config-typescript-esm

Usage

In your eslint.config.js:

import larvit from "@larvit/eslint-config-typescript-esm";
import globals from "globals";

export default [
	...larvit,
	{
		languageOptions: {
			globals: globals.node,
		},
	},
];

globals.node here is the flat-config replacement for the old env: { node: true }. Use globals.browser for browser code.

The TypeScript rules are scoped to *.ts/*.tsx/*.mts/*.cts; plain .js files get the base ESM config only. The bundled typescript-eslint recommended preset is non-type-checked, so no tsconfig wiring is required.
