nrz

Same as nrr or nrn, but even faster.

Want to try out ?

Download latest build artifact from build ci.

To build `nrz` localy

1. Clone this repo

2. Build nrz with (you will need zig installed):

   zig build --release=fast --summary all -Doptimize=ReleaseFast

3. Add <repo dir>/zig-out/bin to PATH

Usage

nrz dev --host

This will run dev command from closest package.json and pass --host and option (it will forward everything you handle it).

nrz eslint ./src

This will run eslint from closest node_modeules/.bin/ folder and pass ./src as arg.
