Add multi-version publishing script with dist-tags

Multi-Version Publishing Script with Dist-Tags

This PR implements a comprehensive publishing script that solves the workspace naming conflict issue outlined in the TODO.md. The script allows publishing all version-specific packages under the unified "libpg-query" name using dist-tags.

🎯 Problem Solved

The repository has multiple packages:

• @libpg-query/v13 (version 13.0.0)
• @libpg-query/v14 (version 14.0.0)
• @libpg-query/v15 (version 15.0.0)
• @libpg-query/v16 (version 16.0.0)
• @libpg-query/v17 (version 17.0.0)

These need unique names in the workspace but should all be published as libpg-query with different dist-tags for easy installation.

🚀 Solution

Created scripts/publish-versions.js that:

1. Handles Workspace Naming Conflicts: Temporarily modifies package.json files during publishing, then restores them
2. Uses Dist-Tags: Publishes with tags pg13, pg14, pg15, pg16, pg17
3. Maintains Version Consistency: Each package keeps its major version (13.0.0, 14.0.0, etc.)
4. Safety Features: Includes dry-run mode, backup/restore, and error handling
5. Selective Publishing: Can publish all versions or specific ones

📋 Features

Core Functionality

• Dynamic Package Discovery: Automatically finds all version packages using the same pattern as analyze-sizes.js
• Temporary Package.json Modification: Changes name to "libpg-query" only during publishing
• Automatic Backup/Restore: Ensures original package.json files are never permanently modified
• Build Integration: Runs pnpm build before publishing each package
• Dist-Tag Publishing: Uses pnpm publish --tag pgXX for each version

Safety & Testing

• Dry-Run Mode: Test the entire workflow without actual publishing
• Error Handling: Graceful failure handling with cleanup
• Progress Reporting: Clear console output showing what's happening
• Publishing Summary: Final report of successes and failures

CLI Interface

# Test all versions
pnpm publish:dry-run

# Publish all versions
pnpm publish:versions

# Publish specific versions
pnpm publish:specific 16,17

# Direct script usage
node scripts/publish-versions.js --dry-run --versions "17"

🧪 Testing Results

Dry-run testing shows the script correctly identifies and processes all packages:

🚀 libpg-query Multi-Version Publisher
=====================================
🔍 DRY RUN MODE - No actual publishing will occur

Found 5 packages to publish:
  - @libpg-query/v13 (v13) -> libpg-query@pg13
  - @libpg-query/v14 (v14) -> libpg-query@pg14
  - @libpg-query/v15 (v15) -> libpg-query@pg15
  - @libpg-query/v16 (v16) -> libpg-query@pg16
  - @libpg-query/v17 (v17) -> libpg-query@pg17

📦 Installation After Publishing

Once published, users can install specific PostgreSQL versions:

npm install libpg-query@pg17  # PostgreSQL 17 parser
npm install libpg-query@pg16  # PostgreSQL 16 parser
npm install libpg-query@pg15  # PostgreSQL 15 parser
npm install libpg-query@pg14  # PostgreSQL 14 parser
npm install libpg-query@pg13  # PostgreSQL 13 parser

🔧 Changes Made

1. Created scripts/publish-versions.js - Main publishing script with full functionality
2. Updated package.json - Added convenient npm scripts:
   • publish:dry-run - Test publishing workflow
   • publish:versions - Publish all versions
   • publish:specific - Publish specific versions
3. Updated TODO.md - Marked "publish setup with name proxy" as completed

🏗️ Implementation Details

The script follows the exact approach outlined in the TODO.md:

• Dynamically generates appropriate package.json during publishing
• Uses pnpm publish --tag <dist-tag> for each version
• Maintains workspace compatibility by restoring original names

The implementation reuses proven patterns from the existing analyze-sizes.js script for package discovery and follows the same code style and structure.

✅ Verification

• Dry-run testing passes for all versions
• Dry-run testing passes for specific versions
• Help documentation is clear and comprehensive
• Error handling and cleanup work correctly
• Package.json backup/restore functionality verified
• All changes committed and pushed to feature branch
