Parser command line options into an object. Uses --key value1 -k value2 syntax.

🏠 Homepage

Install

npm install cli-options-parser

Usage

Your CLI App:

// cli-app.js
import cliToObject from 'cli-options-parser';

const obj = cliToObject();

console.log('⚠️  This is what we got:');
Object.entries(obj).forEach(([key, value]) =>
  console.log(`${key.replace(/^-{1,2}/, '')}: ${value}`)
);

Command line prompt:

/path/to/cli-app.js --name John --age 23 --is-adult

# cliToObject returns { '--name': 'John', '--age': '23', '--isAdult': true }
# cli-app.js prints:
# ⚠️  This is what we got:
# name: John
# age: 23
# is-adult: true

Import the cliToObject() function from cli-options-parser. Call it and store the returned result in a variable. What it will do is read process.argv and return the options in an object as key-value pairs. Keys without values are assigned the value of true.

Syntax

Keys are preceeded with a double dash -- and can optionally be followed by a value. If no value is followed, then the value of true is assigned. For example:

• --name John produces { '--name': 'John' }
• --is-engineer produces { '--is-engineer': true }

Optionally you can use short-hand one-letter keys preceeded with a single dash -. The same rules apply. For example:

• -n John produces { '-n': 'John' }
• -h produces { '-h': true }

Run tests

npm run test
