@lando/argv v1.1.2

ARGV

A very simple module called argv that allows you to:

• Check whether certain flags exist in process.argv
• Get the value of a flag in process.argv

Installation

# With npm
npm install @lando/argv

# With yarn
yarn add @lando/argv

Usage

This module has two functions hasOption and getOption.

hasOption

Checks to see if a flag exists in process.argv.

const argv = require('argv');

// Will return Boolean
const hasDebug = argv.hasOption('--debug'));

getOption

Returns the value of the flag. If the flag is a switch then it will return true|false by default. If the flag has a string value it will return that string value.

// File: myscript.js
const argv = require('argv');

console.log(argv.getOption('--debug'));

The above code will produce the following:

node myscript.js --debug
> true

node myscript.js --debug "trill"
> trill

hyperdrive list --debug=trill
> trill

You also can replace the default Boolean value with the defaultValue option.

// File: myscript.js
const argv = require('argv');

console.log(argv.getOption('--debug', {defaultValue: 'the-truth-is-out-there'}));

node myscript.js --debug
> the-truth-is-out-there
