node package manager


cache dependency manager installs to local machine


npm-cache is a command line utility that caches dependencies installed via npm, bower, jspm and composer.

It is useful for build processes that run [npm|bower|composer|jspm] install every time as part of their build process. Since dependencies don't change often, this often means slower build times. npm-cache helps alleviate this problem by caching previously installed dependencies on the build machine. npm-cache can be a drop-in replacement for any build script that runs [npm|bower|composer|jspm] install.

How it Works

When you run npm-cache install [npm|bower|jspm|composer], it first looks for package.json, bower.json, or composer.json in the current working directory depending on which dependency manager is requested. It then calculates the MD5 hash of the configuration file and looks for a filed named .tar.gz in the cache directory ($HOME/.package_cache by default). If the file does not exist, npm-cache uses the system's installed dependency manager to install the dependencies. Once the dependencies are installed, npm-cache tars the newly downloaded dependencies and stores them in the cache directory. The next time npm-cache runs and sees the same config file, it will find the tarball in the cache directory and untar the dependencies in the current working directory.


npm install -g npm-cache


npm-cache install

To specify arguments to each dependency manager, add the arguments after listing the dependency manager.

For example, to install bower components with the --allow-root option, and composer with the --dry-run option:

npm-cache install bower --allow-root composer --dry-run


npm-cache install # try to install npm, bower, and composer components
npm-cache install bower # install only bower components
npm-cache install bower npm # install bower and npm components
npm-cache install bower --allow-root composer --dry-run # install bower with allow-root, and composer with --dry-run
npm-cache install --cacheDirectory /home/cache/  bower  # install components using /home/cache as cache directory
npm-cache install --forceRefresh  bower # force installing dependencies from package manager without cache
npm-cache install --noArchive  npm # installs dependencies and caches them without compressing
npm-cache clean # cleans out all cached files in cache directory


Though I have a busy day job, I will do my best to add simple feature requests and merge PRs as soon as I can. I know this package is not following many of today's best practices (namely TESTS, a proper branching strategy, and more), but I hope you still find it useful.
