Node.js

Delete all unused global node modules and Node.js executables installed with nvm

Running nvm ls will show you all versions installed, you can use nvm uninstall v12.2.0 for example to uninstall a specific version, however this doesn't remove global npm packages that you installed for this version. It's better to go to ~/.nvm/versions/node folder and rm -rf versions that you don't need.

A useful command to delete all versions that you aren't currently using:

cd ~/.nvm/versions/node; ls -A | grep -v `nvm current` | xargs rm -rf 

Delete all node_modules folders from your projects

Commands taken from this article

Check size of node_modules in folder with your projects

# Mac / Linux cd documents find . -name "node_modules" -type d -prune | xargs du -chs # Windows cd documents FOR /d /r . %d in (node_modules) DO @IF EXIST "%d" echo %d" # --- Example output --- 255M ./someProject/node_modules 482M ./anotherOne/node_modules 707M total 

Delete all node_modules folders

# Mac / Linux find . -name "node_modules" -type d -prune -exec rm -rf '{}' + # Windows FOR /d /r . %d in (node_modules) DO @IF EXIST "%d" rm -rf "%d" 

Yarn and npm cache

yarn cache clean npm cache clean --force 

Xcode

Really nice tool for deleting old simulators, archives and other Xcode junk: https://apps.apple.com/us/app/devcleaner-for-xcode/id1388020431?mt=12

Homebrew

Homebrew periodacaly performs cleanup but if you need some extra space now, you can run:

brew cleanup 

Docker

Docker needs to be running for this to work.
Be aware that docker removes all images that currently aren't used, so if you want to keep something, start it and it won't be deleted. Check docs for more info.

docker system prune -a # add '--volumes' to delete all volumes as well 

If you have some lang/tool/ide that requires cleanup leave a comment and I will add it.
