I Was Tired of Downloading the Same npm Packages—So I Built PackVault
Every JavaScript developer has done this countless times:
npm install
Wait...
Download React.
Download Vite.
Download TypeScript.
Download Tailwind CSS.
Repeat for every new project.
Eventually I started asking myself:
Why am I downloading the same packages over and over again?
That question eventually turned into PackVault.
The Problem
Modern JavaScript development assumes you always have internet access.
But that's not always true.
- ✈️ Working on a flight
- 🌐 Slow or unstable internet
- 🎓 Workshops with dozens of students
- 🔒 Air-gapped environments
- 💻 Setting up multiple development machines
Even if you've already downloaded a package before, you'll often end up downloading it again.
So I Built PackVault
PackVault is an offline-first package caching CLI for JavaScript developers.
Instead of repeatedly downloading dependencies, PackVault lets you cache them once and reuse them whenever you need them.
# Cache packages
packvault sync react vite tailwindcss
# Install later—even offline
packvault install react
Current Features
- 📦 Offline package installation
- 🔒 Integrity verification
- 📄 Lockfile-aware syncing
- 🚀 Offline project templates
- 💾 Portable package vaults
Coming Soon
- 🌐 LAN package sharing
- 🔄 Peer-to-peer synchronization
- 🖥️ Local registry server
- 🎓 Classroom mode
What I Learned
Building PackVault taught me much more than I expected.
I learned about:
- CLI architecture
- Package registries
- Dependency resolution
- File systems
- Caching strategies
- Software design
It started as a small side project but quickly became one of the most technically challenging things I've worked on.
I'd Love Your Feedback
I'm actively building PackVault and would love feedback from the community.
