Packmate is a modern CLI tool for managing, updating, and cleaning up your Node.js project dependencies.

It supports npm, pnpm, and yarn. With an intuitive interactive UI and powerful performance optimizations, Packmate helps you keep your project healthy and up-to-date—faster and safer than ever.

• ⚡ Performance: 6x faster with 3-level caching system (memory + disk + network)
• 🎯 Accuracy: 90%+ unused package detection with dev tool intelligence
• 🛡️ Safety: Smart fallback for package managers, unused packages excluded from updates
• 🎨 Clarity: Grouped UI sessions (Patch/Minor/Major) with color-coded updates
• 🔧 Flexibility: Full configuration support via packmate.config.json
• 🌍 Modern: Clean, professional English interface with intuitive workflows

• 3-Level Caching System: Memory → Disk (1hr TTL) → Network
  • First run: Standard speed
  • Second run: 6x faster with cached registry data
• Parallel Processing: Multi-core CPU utilization for file scanning (2-4x faster)
• Adaptive Concurrency: Dynamic request throttling based on CPU cores (8-16 concurrent)

• Enhanced Unused Detection (90%+ accuracy):
  • Dynamic import detection: import('module')
  • Conditional require detection: try-catch, if blocks
  • DevDependencies intelligence: Recognizes build tools, linters, type definitions
  • Cross-validation: precinct + depcheck for high confidence
• Update Detection:
  • Grouped by Patch/Minor/Major with color coding
  • Unused packages automatically excluded from update suggestions
  • Semver-aware version comparison
• Installation Detection: Finds declared but not installed packages

• Grouped UI Sessions:
  • 🔹 Patch Updates (Green): Bug fixes, safe to update
  • 🔸 Minor Updates (Yellow): New features, backward compatible
  • 🔶 Major Updates (Red): Breaking changes, requires review
  • 🗑️ Unused Packages: High/Medium confidence levels
  • 📥 Not Installed: Missing declared dependencies
  • ✅ Up-to-date: Informational list (non-selectable)
• Safety Features:
  • Confirmation prompt for major updates
  • Breaking change warnings
  • Clear action summaries
• Visual Enhancements:
  • Color-coded version changes
  • Progress bars for long operations
  • Fixed console box alignment

• Smart Package Manager Detection:
  • Auto-detects from lock files (pnpm-lock.yaml, yarn.lock, package-lock.json)
  • Verifies installation status
  • Auto-fallback to available manager with helpful tips
• Configurable Options:
  • Custom ignore patterns (glob support)
  • Analysis modes (conservative/moderate/aggressive)
  • UI customization (default selections, color schemes)
  • Cache settings (duration, location)

npm install -g packmate
# or
pnpm add -g packmate
# or
yarn global add packmate

You can also run it instantly with:

Packmate automatically caches registry responses for faster subsequent runs. Clear cache if needed:

# Windows
del /q %TEMP%\packmate-cache\*

# Linux/Mac
rm -rf /tmp/packmate-cache/*

Cache location:

• Windows: C:\Users\<user>\AppData\Local\Temp\packmate-cache
• Linux/Mac: /tmp/packmate-cache
