@configg/oxc

oxfmt and oxlint presets.

bun add -d @configg/oxc oxfmt oxlint oxlint-tsgolint

Formatter

@configg/oxc/fmt exports configs, a record of plain config objects. Pass one to oxfmt's defineConfig().

// oxfmt.config.ts
import { defineConfig } from 'oxfmt'
import { configs } from '@configg/oxc/fmt'

export default defineConfig(configs.client)

• client: the shared base plus Tailwind class sorting (class, className, cx, createVariants) and import grouping (react, external, components, utils, relative).
• scripts: the shared base, for tooling and config files.
• server: the shared base.

Linter

@configg/oxc/lint exports configs. Pass one to oxlint's defineConfig().

// oxlint.config.ts
import { defineConfig } from 'oxlint'
import { configs } from '@configg/oxc/lint'

export default defineConfig(configs.client)

• client: browser env, type-aware, with rules relaxed for component code. Its **/*.spec.{ts,tsx} override enables the Vitest env and Testing Library rules, so it needs eslint-plugin-testing-library.
• scripts: Node env, type-aware, for tooling and config files.

The Oxlint presets don't enable anti-slop. antiSlop from @configg/oxc/lint is an opt-in set with the plugin and all 18 rules as errors; unicorn/prefer-reflect-apply is off. See UPSTREAM.md for its source and update policy.

import { antiSlop, configs } from '@configg/oxc/lint'

export default defineConfig({
	...configs.client,
	jsPlugins: [...antiSlop.jsPlugins],
	rules: { ...configs.client.rules, ...antiSlop.rules },
})

If your config has its own jsPlugins, keep the anti-slop entry in that array. The plugin ships as TypeScript, so run oxlint under Bun (bunx --bun oxlint): Node refuses to strip types from files in node_modules.

Both presets allow up to two classes per file, allow reduce(), allow process.exit() (CLI scripts and shutdown handlers exit with a status code on purpose) and allow short identifiers (eslint/id-length is off). They turn import/prefer-default-export off, since named exports are the convention (it matters once a config adds the import plugin), and unicorn/number-literal-case off, since oxfmt and Prettier write hex digits in lowercase. async/await is allowed (oxc/no-async-await is off), continue is allowed (eslint/no-continue is off), and functions may run to 100 lines (blank lines and comments not counted) and 30 statements. Template expressions allow booleans, numbers, nullish values and never; other types follow Oxlint's defaults.

Peer dependencies

oxfmt, oxlint, oxlint-tsgolint and eslint-plugin-testing-library are all optional peers, so you install only the ones the presets you use need.
