This is a utility that will remove outdated dependencies from your node_modules. The reason why this was built is to allow deploy environments easier ways to cache their packages. Right now if you run npm install with a shrink wrap file and you have outdated cached node modules nothing will happen because it assumes the package installed is the correct version of the package. All this script does is check the version of the installed packages against the versions in the shrink-wrap and removes the folder to make npm install treat that as a dependency that has not been installed yet.
$ npm install -g npm-remove-outdated
thats it :D
$ npm-remove-outdated && npm install
This package can work with either a npm-shrinkwrap.json file or a package.json file. When using shrinkwrap the version check is an explicit === to the version in the package file. When no shrinkwrap is found the package.json is used. Then the version checking is based off of semver's satisfies method.
npm i
