molt
CLI disk cleanup tool — shed the cruft like a lobster sheds its shell.
About This Project
Every developer knows the pain: your disk is full, and somewhere in your projects folder there are gigabytes of node_modules, build artifacts, and cache files just sitting there.
molt is a CLI tool that finds and helps you remove this cruft. Named after the process where lobsters shed their old shells to grow, molt helps your projects shed unnecessary weight.
Run it in any directory and it'll scan for common space hogs: node_modules folders, dist/build directories, .cache folders, and more. Then it shows you what it found and lets you decide what to clean.
Features
- •Scans directories recursively for cleanup targets
- •Finds node_modules, build artifacts, caches, and logs
- •Shows size of each found directory
- •Interactive mode to select what to delete
- •Dry-run mode to preview without deleting
- •Fast and lightweight
Challenges
The main challenge was making the scanning fast enough to be useful. Early versions would hang on large directory trees. The solution was to use async iteration and skip directories that are obviously not interesting (like .git internals).
What I Learned
Sometimes the best tool is a simple one. molt doesn't try to be clever about what to delete — it just finds the obvious culprits and lets you decide. That simplicity makes it trustworthy.
