@getresponse/oxlint-config

---

An opinionated Oxlint ruleset targeting TypeScript + React web apps.

Requirements

• Oxlint ^1.62.0
• Node >=22.18 (or ^20.19) — required by Oxlint's TypeScript config support

Installation

npm i -D oxlint @getresponse/oxlint-config

For type-aware TypeScript rules (recommended for TS projects), also install oxlint-tsgolint:

npm i -D oxlint-tsgolint

Usage

Create oxlint.config.ts in your project root:

import { defineConfig } from 'oxlint';
import config from '@getresponse/oxlint-config';

export default defineConfig({
    extends: [config],
});

With local overrides:

import { defineConfig } from 'oxlint';
import config from '@getresponse/oxlint-config';

export default defineConfig({
    extends: [config],
    overrides: [
        {
            files: ['src/legacy/**/*.ts'],
            rules: {
                'typescript/no-explicit-any': 'off',
            },
        },
    ],
});

Then run:

npx oxlint

TypeScript

Oxlint walks up from each linted file to find the nearest tsconfig.json automatically. Type-aware rules require the oxlint-tsgolint package; this config enables them automatically when TypeScript is detected in your project's dependencies.

For most projects, no extra configuration is needed.

When you might want a dedicated tsconfig.oxlint.json

The package does not look for or use a separate lint-time tsconfig (this differs from the old ESLint package which auto-detected tsconfig.eslint.json). If you need a different TS configuration for linting than for building, point oxlint at it via CLI:

{
  "scripts": {
    "lint": "oxlint --tsconfig ./tsconfig.oxlint.json"
  }
}

Reasonable use cases:

• Your tsconfig.json excludes test files (exclude: ["**/*.test.ts"]) but you want type-aware rules to still work in tests
• Monorepo with several tsconfig.jsons and you need oxlint to use a specific root
• Path mappings (paths / baseUrl) that exist only in a separate config

If none of these apply, skip it.

Dynamic rules

Plugin rulesets are enabled automatically when the corresponding package is detected in your package.json dependencies:

Detected dependency	Preset enabled
typescript	TypeScript rules (with type-aware analysis)
react	React + React Hooks rules
jest	Jest rules
@playwright/test / playwright	Playwright rules (scoped to test files via playwright.config.*)

Files ignored by .gitignore are skipped automatically.

Stylistic rules

Stylistic rules (@stylistic/*) are loaded via Oxlint's JS Plugins bridge using @stylistic/eslint-plugin — Oxlint itself doesn't implement most stylistic rules natively. This trades raw speed for compatibility; if you switch to a dedicated formatter (e.g., oxfmt, Prettier), you can override these rules off in your local config.

Mixins

Additional opt-in rulesets:

import { defineConfig } from 'oxlint';
import config from '@getresponse/oxlint-config';
import a11y from '@getresponse/oxlint-config/a11y';

export default defineConfig({
    extends: [config, a11y],
});

Mixin	Description
@getresponse/oxlint-config/a11y	Accessibility rules from Oxlint's native jsx-a11y plugin, with extras bridged via eslint-plugin-jsx-a11y
