nyxx

A tiny CLI that maps short, memorable commands to the long ones you always forget. Define your scripts once in nyxx.yml — nyxx handles the rest.

Install

npm install -g nyxx
# or
pnpm add -g nyxx

Usage

Run nyxx with no arguments to see all available scripts at a glance.

nyxx

Run any command you've defined:

nyxx dev web
nyxx build ui --watch
nyxx release api beta

Configuration

Create a nyxx.yml at the root of your project. Each command has an input (what you type) and an output (what actually runs). Use {{double braces}} for template variables, and defaults for optional arguments.

commands:
  dev:
    input: 'dev <app>'
    output: 'pnpm --filter @my-org/{{app}} dev'

  build:
    input: 'build <pkg> [...args]'
    output: 'pnpm --filter @my-org/{{pkg}} build {{args}}'

  release:
    input: 'release <pkg> [tag]'
    output: 'pnpm --filter @my-org/{{pkg}} publish --tag {{tag}} --access public'
    defaults:
      tag: latest

Argument syntax

Syntax	Meaning
<name>	Required argument
[name]	Optional argument
[...name]	Optional, captures all remaining arguments

Defaults kick in for optional arguments when nothing is passed.
