npm-cache

A command-line utility that caches dependencies installed via npm, bower, jspm, and composer to reduce build times. It works by hashing the configuration file (package.json, bower.json, etc.) and storing the resulting tarball in a local cache directory (~/.package_cache by default). On subsequent runs, it extracts the cached tarball instead of re-installing. The latest version is 0.8.0 (last updated in 2017), with no active development. It is a simple, pragmatic solution for CI environments that run installs repeatedly, but lacks tests and modern best practices.
