eslint-config-extreme

library3.4.0jsnpmunverified

A comprehensive, modular ESLint configuration for modern JavaScript and TypeScript projects. Version 3.4.0 supports ESLint v9+ flat config format and ships with all plugins included out of the box. This package provides pre-built configurations for environment-agnostic, React/web, Node.js, and full-stack projects, with TypeScript support always included. Unlike alternatives like eslint-config-standard or airbnb, it bundles all dependences and requires zero manual plugin setup. The package is ESM-only, written in TypeScript with type definitions, and follows a 'batteries-included' philosophy.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

configs

✓ import { configs } from 'eslint-config-extreme'

✗ const { configs } = require('eslint-config-extreme')

ESM-only package; require() will fail. Use dynamic import or ESM context.

configs.base

✓ import { configs } from 'eslint-config-extreme'; ...configs.base

✗ import base from 'eslint-config-extreme/base'

Named export from root only; subpath exports are not supported.

configs.recommended

✓ import { configs } from 'eslint-config-extreme'; export default await configs.recommended

✗ export default configs.recommended

configs.recommended (and similar) return a Promise; must be awaited in flat config.

Creates an ESLint flat config using base and TypeScript rules. Shows both manual combination and async preset usage.

import { configs } from 'eslint-config-extreme'; export default [ ...configs.base, ...configs.typescript ]; // Or use a recommended preset (async): // export default await configs.recommended;

Debug

Known issues

breakingESM-only import: CommonJS require() throws ERR_REQUIRE_ESM.

fix

Use ESM ("type": "module" in package.json) or dynamic import().

affects: >=3.0.0

breakingFlat config only: ESLint <8.40 with rc configs will not work.

fix

Migrate to ESLint v8.40+ and use eslint.config.js.

affects: >=1.0.0

deprecatedconfigs.all is deprecated in favor of configs.recommendedAll.

fix

Replace .all with .recommendedAll.

affects: >=3.0.0

gotchaconfigs.recommended (and similar) are async; awaiting is required.

fix

Use await configs.recommended in your flat config export.

affects: >=1.0.0

gotchaTypeScript is a peer dependency; using TypeScript configs without installing typescript will fail.

fix

Install typescript: npm install -D typescript.

affects: >=1.0.0
