oxlint

Shareable Oxlint and Oxfmt configs for Vite+ apps and TypeScript libraries.

• @qntx/oxlint — correctness and type safety (config, react, merge).
• @qntx/oxfmt — printer (fmt). printWidth: 100, double quotes, semicolons, sortImports on.

Compose in one vite.config.ts. Do not use Oxlint extends (it merges only rules / plugins / overrides and drops env / options / settings / ignorePatterns).

The sibling repo qntx/oxfmt is a Vite+ starter. @qntx/oxfmt lives here.

Requires oxlint ^1.82.0. Vite+ 0.3.1 nests 1.81.0; this repo overrides that. Vite+ 0.3.2 and later already satisfy the peer (0.3.3 nests 1.83.0). @qntx/oxfmt accepts oxfmt >=0.66.0 <1.0.0.

Install

bun add -d @qntx/oxlint @qntx/oxfmt

Do not add oxlint, oxfmt, or oxlint-tsgolint to a Vite+ app. vp already nests them.

Recipes

Vite+ React

import { defineConfig } from "vite-plus";
import { react } from "@qntx/oxlint";
import { fmt } from "@qntx/oxfmt";

export default defineConfig({
  lint: react,
  fmt,
});

react already includes the core TypeScript/ESLint/Vitest table plus native react / jsx-a11y.

react assumes the project is compiled by React Compiler: it enables the native compiler rules, forbids useMemo / useCallback / memo (named, namespace, and React.* access), and turns off rules that only push toward manual memoization. Setting your own eslint/no-restricted-imports or eslint/no-restricted-properties replaces the preset entry, so copy its react entry into yours.

TypeScript library

import { defineConfig } from "vite-plus";
import { config } from "@qntx/oxlint";
import { fmt } from "@qntx/oxfmt";

export default defineConfig({
  lint: config,
  fmt,
});

config does not enable React plugins.

Overrides

import { defineConfig } from "vite-plus";
import { config, merge } from "@qntx/oxlint";
import { fmt } from "@qntx/oxfmt";

export default defineConfig({
  lint: merge(config, { rules: { "eslint/no-console": "off" } }),
  fmt: { ...fmt, printWidth: 120 },
});

Drop default ignore patterns with { ignorePatterns: undefined }. Replace them with { ignorePatterns: [] } then set a new list. Top-level fmt keys override with spread; nested object settings (sortImports and friends) extend by spreading the nested object — see the @qntx/oxfmt README.

CLI

// oxlint.config.ts
export { config as default } from "@qntx/oxlint";

// oxfmt.config.ts
export { fmt as default } from "@qntx/oxfmt";

Vite+ projects should put lint and format in vite.config.ts.
