Migrate pnpm workspace catalogs to bun catalog format.

Usage

bash

What it does

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

Before (pnpm-workspace.yaml)

yaml

After (package.json)

json

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

Requirements

  • Bun v1.1.30 or higher (for catalog support)
  • Existing pnpm workspace with catalog configuration

After migration

  1. Remove pnpm files (optional):

    bash

  2. Install dependencies with bun:

    bash

  3. Verify:

    bash

Features

  • ✅ Migrates catalog from pnpm-workspace.yaml to root package.json
  • ✅ Preserves catalog: references in workspace packages
  • ✅ Merges named catalogs (if any) into single catalog
  • ✅ Sorts catalog entries alphabetically
  • ✅ Adds workspaces configuration if missing

Notes

  • Bun's catalog feature is equivalent to pnpm's catalog
  • Named catalogs (pnpm's catalogs:) are merged into one catalog
  • The codemod preserves all existing catalog: references
