monoswan

monoswan keeps package configuration consistent across a monorepo. Define shared package shapes once, check them with rules, and use the same definitions to create new packages.

• Centrally managed configuration: Share package.json, TypeScript, JSON, and text configuration through composable variants.

• Rules & consistency: Check packages with built-in or custom rules, with autofix support.

• Package templates: Create packages from variant defaults and initialization content.

monoswan.config.ts

import { defineConfig, enforceVariants, sortPackageJson } from "monoswan";

export default defineConfig({
  variants: {
    "my-library": {
      packageJson: { type: "module" },
      tsConfig: { compilerOptions: { strict: true } },
      initialization: {
        packageJson: { version: "0.0.0" },
        additionalTextFiles: { "src/index.ts": "export {};\n" },
      },
    },
  },
  rules: [enforceVariants(), sortPackageJson()],
});
