How to clean node modules folder of packages that are not in package json

Question

Assume I install project packages with npm install that looks into package json for modules to be installed  After a while I see that I don t need some specific module and remove its dependency from package json  Then I remove some other modules from package json because they are not needed anymore and others are replaced with alternatives    Now I want to clean node modules folder so that only modules listed in package json stay there and the rest must go  something like npm clean  I know I can remove them manually but would like to have some nice ready to use sugar functionality for that

Just in-case somebody needs it  here s something I ve done recently to resolve this  npm ci - If you want to clean everything and install all packages from scratch  -It does a clean install  if the node modules folder exists  npm deletes it and installs a fresh one  -It checks for consistency  if package-lock json doesn   t exist or if it doesn   t match the contents of package json  npm stops with an error  https   docs npmjs com cli v6 commands npm-ci npm-dedupe - If you want to clean-up the current node modules directory without deleting and re-installing all the packages Searches the local package tree and attempts to simplify the overall structure by moving dependencies further up the tree  where they can be more effectively shared by multiple dependent packages  https   docs npmjs com cli v6 commands npm-dedupe

You could remove your node modules  folder and then reinstall the dependencies from package json   rm -rf node modules  npm install   This would erase all installed packages in the current folder and only install the dependencies from package json  If the dependencies have been previously installed npm will try to use the cached version  avoiding downloading the dependency a second time

I think you re looking for npm prune     npm prune   lt name gt    lt name            This command removes  extraneous  packages  If a package name is   provided  then only packages matching one of the supplied names are   removed        Extraneous packages are packages that are not listed on the   parent package s dependencies list    See the docs  https   docs npmjs com cli prune
