Npm-cache-install NPM

npm-cache-install

Offline npm install, using locally cached packages.

The idea is based on npm-cache, but instead of caching whole node_modules directory, npm-cache-install will cache each package seperately, so changing any of them will not invalidate whole cache.

Also, any npm options will be passed to npm install (like --registry, etc.)

Usage:

1. npm-cache-install install options

Run it instead of npm install [options], it will:

read package.json, get a list of dependencies
for each dependency
- if already installed and satisfies specified version, continue
- if cached in cache directory (~/.npm-cache-install), restore to ./node_modules/[dependency], continue
- actually runs npm install dependency@version [options],
- save installed package to cache directory

2. npm-cache-install clean

rm -rf cache directory for you.

Caveat:

Windows is not supported for now
Does not differentiate node version and node architecture (if node version changes, please clean cache directory manually)
Bad support for peerDependency, which might cause problems.
Not tested with npm@3
