Open Source


CLI tool with ~250k+ downloads/month on npm to find unused code in typescript projects. Added a small feature to allow specfifying a pattern to exclude files from counting toward code use, for instance .test.ts - so that functions that were tested but not used anywhere else in the codebase could still be identified and removed.



A CLI tool written in typescript to get crypto asset prices.
