nrn

Cross package manager scripts runner (and more). Why, if there is ni ? Switching node versions will require you to reinstall the ni every time and i forgor to do that. I tried nrr, it's fast, cool and maintained, but it lacks some of core package manager features like install, remove or add.

Build

$ nim c ./src/nrn.nim

Benchmarks

Just for fun, i didn't expect to be (nearly) on par with rust, using nim, but it's cool how high you can jump with this little language. I used decent sized package.json file from my Keycap project and added start script with node ./index.js (where index.js is an empty file).
