bun-catalogs-to-pnpm

Migrate bun catalog to pnpm workspace catalogs format.

Usage

# Run the migration
npx codemod bun-catalogs-to-pnpm

# Or run directly
npx bun-catalogs-to-pnpm

What it does

This codemod migrates your bun catalog configuration back to pnpm's workspace catalog format:

Before (package.json)

{
  "workspaces": {
    "packages": ["packages/*"],
    "catalog": {
      "lodash": "^4.17.21",
      "react": "^19.2.0",
      "typescript": "^5.3.0"
    }
  }
}

After (pnpm-workspace.yaml)

packages:
  - 'packages/*'

catalog:
  lodash: ^4.17.21
  react: ^19.2.0
  typescript: ^5.3.0

The catalog is removed from package.json and moved to pnpm-workspace.yaml.

All workspace packages using catalog dependencies (catalog:) will continue to work with pnpm.

Requirements

• pnpm v9.5.0 or higher (for catalog support)
• Existing bun workspace with catalog configuration in package.json

After migration

1. Remove bun files (optional):

   rm bun.lockb

2. Install dependencies with pnpm:

   pnpm install

3. Verify:

   cat pnpm-workspace.yaml

Features

• ✅ Migrates catalog from root package.json to pnpm-workspace.yaml
• ✅ Preserves catalog: references in workspace packages
• ✅ Creates pnpm-workspace.yaml if it doesn't exist
• ✅ Updates existing pnpm-workspace.yaml if present
• ✅ Removes catalog from root package.json

Notes

• This is the reverse operation of pnpm-catalogs-to-bun
• All catalog: references in workspace packages remain unchanged
• The codemod creates or updates pnpm-workspace.yaml automatically
