@staratlas/configs

Shared configuration package for Star Atlas projects.

This package supports multiple toolchains (oxc, vite, typescript, plus legacy eslint/prettier exports), but you do not need to use all of it.

Get Exactly What You Need (Important)

What is actually minimal?

There are two different kinds of “size”:

1. Usage size (what your project actually imports/extends)
2. Install size (what the package manager downloads)

This package is a single npm package, so install-time contents are not tree-shaken.

What you can minimize very effectively is the usage surface by using subpath exports.

Fast Matrix: Install Only What You Need

You need	Install	Use
OXC lint + format only	@staratlas/configs oxlint oxfmt typescript	@staratlas/configs/oxc/oxlint-master.json + @staratlas/configs/oxc/oxfmt-master.json
OXC lint (React)	@staratlas/configs oxlint typescript	@staratlas/configs/oxc/oxlint-react.json
OXC lint (Next)	@staratlas/configs oxlint typescript	@staratlas/configs/oxc/oxlint-next.json
TypeScript base only	@staratlas/configs typescript	@staratlas/configs/base.json
TypeScript + Solid JSX	@staratlas/configs typescript	@staratlas/configs/base.json + @staratlas/configs/solid.json
Vite helpers (library/site config helpers)	@staratlas/configs vite typescript	@staratlas/configs/vite
Vite + Solid (OXC plugin)	@staratlas/configs vite typescript solid-js vite-plugin-solid-oxc solid-jsx-oxc vite-plugin-solid-svg	@staratlas/configs/vite + solidConfig()

Notes:

• This matrix minimizes what your project uses, not what npm/pnpm downloads.
• @staratlas/configs is one package, so install-time contents are shared.
• Peer deps are marked optional, so you can skip unrelated tools.

Use Subpath Exports (Recommended)

Use only the subpaths you need instead of importing broad modules.

OXC only (smallest usage surface)

Use these files directly:

• @staratlas/configs/oxc/oxlint-master.json
• @staratlas/configs/oxc/oxlint-react.json
• @staratlas/configs/oxc/oxlint-next.json
• @staratlas/configs/oxc/oxfmt-master.json

Example package.json scripts:

{
  "scripts": {
    "lint": "oxlint -c ./node_modules/@staratlas/configs/oxc/oxlint-master.json .",
    "format": "oxfmt --check -c ./node_modules/@staratlas/configs/oxc/oxfmt-master.json .",
    "format:fix": "oxfmt -c ./node_modules/@staratlas/configs/oxc/oxfmt-master.json ."
  }
}

If you are using React or Next, swap the lint config:

• React: oxlint-react.json
• Next: oxlint-next.json

TypeScript only

Use TS config subpaths only:

• @staratlas/configs/base.json
• @staratlas/configs/solid.json (only if using Solid)

Example tsconfig.json (library/app):

{
  "extends": ["@staratlas/configs/base.json"],
  "include": ["src"]
}

Example Solid project:

{
  "extends": ["@staratlas/configs/base.json", "@staratlas/configs/solid.json"],
  "include": ["src"]
}

Vite helpers only

Import only @staratlas/configs/vite:

import { combineConfigs, libConfig, cleanupConfig } from '@staratlas/configs/vite';
import type { UserConfig } from 'vite';

export default combineConfigs(
  libConfig('src/index.ts'),
  cleanupConfig(),
) satisfies UserConfig;

Solid (OXC plugin) example:

import { combineConfigs, libConfig, cleanupConfig, solidConfig } from '@staratlas/configs/vite';
import type { UserConfig } from 'vite';

export default combineConfigs(
  libConfig('src/index.tsx'),
  cleanupConfig(),
  solidConfig({
    solidPlugin: {
      hydratable: true
    }
  }),
) satisfies UserConfig;

Install Only the Tooling You Use

@staratlas/configs exposes multiple surfaces, but its peers are marked optional so you can install only the tools you actually run.

OXC-only project (recommended default)

pnpm add -D @staratlas/configs oxlint oxfmt typescript

Vite library project (non-Solid)

pnpm add -D @staratlas/configs vite typescript

Add Vite plugin peers only if you use helpers that need them.

Solid + Vite project

pnpm add -D @staratlas/configs vite typescript solid-js vite-plugin-solid-oxc solid-jsx-oxc vite-plugin-solid-svg

How to Reduce Size / Complexity Further

1. Prefer subpaths over broad usage

Good:

• @staratlas/configs/oxc/oxlint-master.json
• @staratlas/configs/base.json
• @staratlas/configs/vite

Avoid (when unnecessary):

• importing/using multiple surfaces if you only need one
• adding ESLint/Prettier dependencies if you are standardizing on OXC

2. Keep tooling local to the project that needs it

In a monorepo, only install Vite/Solid deps in frontend packages (or root if shared by policy). Backend/CLI packages can use only TS + OXC.

3. Copy configs locally if you need zero package coupling

If a project must minimize dependency coupling, copy the exported JSON config into that repo and pin your own tool versions. You lose centralized updates, but gain maximum independence.

Current Exports

OXC

• @staratlas/configs/oxc/oxlint-master.json (framework-neutral strict anti-tech-debt baseline)
• @staratlas/configs/oxc/oxlint-react.json (React + JSX a11y strict variant)
• @staratlas/configs/oxc/oxlint-next.json (Next strict variant)
• @staratlas/configs/oxc/oxfmt-master.json

TypeScript

• @staratlas/configs/base.json
• @staratlas/configs/solid.json

Vite

• @staratlas/configs/vite

Legacy (still supported)

• @staratlas/configs/eslint
• @staratlas/configs/prettier

These remain for compatibility. OXC is the default lint/format path for this package.

Quick Start Recipes

Minimal OXC + TS project

pnpm add -D @staratlas/configs oxlint oxfmt typescript

package.json

{
  "scripts": {
    "lint": "oxlint -c ./node_modules/@staratlas/configs/oxc/oxlint-master.json .",
    "format": "oxfmt --check -c ./node_modules/@staratlas/configs/oxc/oxfmt-master.json .",
    "format:fix": "oxfmt -c ./node_modules/@staratlas/configs/oxc/oxfmt-master.json ."
  }
}

tsconfig.json

{
  "extends": ["@staratlas/configs/base.json"],
  "include": ["src"]
}

Minimal Vite library

pnpm add -D @staratlas/configs vite typescript

vite.config.ts

import { cleanupConfig, combineConfigs, libConfig } from '@staratlas/configs/vite';

export default combineConfigs(libConfig('src/index.ts'), cleanupConfig());

Maintainers (this package)

This package itself is OXC-first:

• pnpm lint -> oxlint
• pnpm format -> oxfmt --check

Legacy build/export surfaces (eslint, prettier) are still published for downstream compatibility.
