I just freed up 3GB of disk space due to random node_modules directories laying around old projects and experiments on my computer.
The project is called npkill and I found it on Reddit today. I have used disk analysis tools before, but they have made it hard to find small files which eat disk. Yes, Grand Perspective helped me find out I had 15 instances of Chromedriver due to node_modules, due to different open source and client projects. But npkill has helped be truly reclaim my disk.
Comments like these make the Drupal community such an awesome open source ecosystem to work within. Thanks, Mateu ?
