A simple script that hashes the package.json file. Stores a archive in cache folder. On next install checks if there is a file with the same hash. If so it extracts that else it will do "npm install" and then create a cached hash archive.

This script idea is heavily based on npm-cache by swarajban. But without bower and composer compatibility . I suggest you check his out.

NOTE: this scripts requires 7zip command-line tool to work

Install with brew

brew install p7zip

Install with Chocolatey

choco install 7zip.commandline

npm install -g npm-package-cache

npm-package-cache install

You can also add -f to make do an npm install --force if you need to

npm-package-cache install -f

To remove all cached files do

npm-package-cache clean

This script is used for personal projects. Maintenance hasn't been thought out.
