Node.js

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

Runningnvm ls will show you all versions installed, you can usenvm 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 andrm -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` | xargsrm-rf

Delete all node_modules folders from your projects

Yarn and npm cache

yarn cache cleannpm 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

Homebrewperiodacaly 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. Checkdocs 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.
