@earthos/config

Shared build, lint, and test presets for EarthOS packages and plugins.

The single source of truth for tooling across the monorepo: a flat ESLint config, a set of layered tsconfigs, Prettier options, tsup build presets (one for framework packages, one for plugins), and a Vitest preset. Every other @earthos/* package and plugin extends these, so a rule or compiler flag changes in one place. The presets are plain JS/JSON with no build-tool dependency of their own; only ESLint is a peer.

Install

pnpm add -D @earthos/config eslint

eslint (^9) is a peer dependency. Everything else the presets need is bundled.

Usage

ESLint (eslint.config.js):

import earthos from '@earthos/config/eslint';

export default earthos;

TypeScript (tsconfig.json), extend the layer that fits the package (base, react-library, nextjs, or plugin):

{
  "extends": "@earthos/config/tsconfig/react-library.json",
  "include": ["src", "tests"]
}

Build (tsup.config.ts), packagePreset for framework packages, pluginPreset for @earthos/plugin-*, both accept overrides:

import { defineConfig } from 'tsup';
import { packagePreset } from '@earthos/config/tsup-package';

export default defineConfig(packagePreset({ external: ['react', 'three'] }));

Tests (vitest.config.ts):

import { defineConfig } from 'vitest/config';
import { vitestPreset } from '@earthos/config/vitest';

export default defineConfig(vitestPreset({ environment: 'jsdom' }));

Prettier is exposed at @earthos/config/prettier (JSON) for the prettier key or a .prettierrc reference.

See docs/PLUGIN_GUIDE.md for how the plugin build split (pluginPreset) maps to the manifest/provider/renderer module layout, and docs/ARCHITECTURE.md for the monorepo layout.
