argv

tips

• all starts with --
• no boolean like --foo=true use --foo or --no-foo
• supports string array --filter=pkg/* --filter=ext/* returns {filter: ['pkg/*', 'ext/*']}
• after -- will save to __
• the same key overwrites the previous one, excepts for string

Install

pnpm add @yme/argv

Usage

import parser from '@yme/argv';

const argv = parser(process.argv.slice(2));
// => {_: [...], ...}

const hello = parser(['--have', '--a', '--good=6', '--day=today', '--no-bad', 'banana']);
// => {_: ['banana'], have: true, a: true, good: 6, day: 'today', bad: false}

// duplicate keys
const arr = parser(['--filter=packages/*', '--filter=exts/*']);
// => {filter: ['packages/*', 'exts/*']}

const overwrite = parser(['--foo', '--no-foo', '--bar', '--bar=bar']);
// => {foo: false, bar: 'bar'}

// camelcase key
const k = parser(['--foo-bar']);
// => {fooBar: true}
