node_modules Black Hole: Find Dead Projects Eating Your Mac

Fifty half-finished repos. Fifty node_modules folders. 50 GB gone — and npm does not clean them for you.

Where they hide

• ~/Projects/**/node_modules
• ~/Developer/**/node_modules
• Old clones in ~/Downloads or Desktop

Terminal power users run find ~ -name node_modules. Everyone else needs a visual map.

Safe cleanup rules

• Do not delete node_modules in a repo you actively work on today.
• Prefer removing whole dead project folders, not random nested deps.
• After delete, npm install restores a active project in minutes.

FreeUpMac tags node_modules blocks as Review on the treemap. Sort the Largest files list, jump to the folder, confirm, then Trash with Pro.

Who this helps

US and Canada devs with 512 GB MacBook Pros are the worst hit — local AI models and Docker already compete for the same disk.
