Overview
--------
Modern CLI arguments parser for node.js (TypeScript / JavaScript).
Setup

description: "Operations to run",
type: 'string',
nargs: '+',
choices: ['build', 'clear', 'sync', 'start', 'stop'],
},
{
name: '--mode',
description: "Run mode",
type: 'string',
nargs: '?',
choices: ['dev', 'test', 'prod'],
default: 'prod',
},
{
name: '--cpu',
description: "CPU cores count to use",
type: 'number',
nargs: '?',
default: 1,
},
{
name: '--use-gpu',
description: "Use GPU flag",
type: 'boolean',
const: true,
default: false,
},
{
name: '--extra-services',
alias: '-e',
description: "Extra services to include",
type: 'string',
nargs: '*',
},
]);
console.log(parser.help);

const containerName = parsedArgs.get('container');
console.log(containerName); // 'main'
const operations = parsedArgs.get('operations');
console.log(operations); // ['clear', 'build', 'start', 'sync']
const mode = parsedArgs.get('--mode');
