Command-Line Argument Parsing Libraries

Command-line argument parsing libraries are essential tools in Node.js development, enabling developers to easily handle user inputs from the command line. These libraries provide functionalities to define commands, options, and arguments, making it simpler to build command-line interfaces (CLIs) for applications. They help streamline the process of capturing user input, validating it, and providing helpful feedback, ultimately enhancing the user experience and making applications more interactive and user-friendly.

Description

Yargs helps you build interactive command line tools, by parsing arguments and generating an elegant user interface.

It gives you:

  • commands and (grouped) options (my-program.js serve --port=5000).
  • a dynamically generated help menu based on your arguments:
mocha [spec..]

Run tests with Mocha

Commands
  mocha inspect [spec..]  Run tests with Mocha                         [default]
  mocha init <path>       create a client-side Mocha setup at <path>

Rules & Behavior
  --allow-uncaught           Allow uncaught errors to propagate        [boolean]
  --async-only, -A           Require all tests to use a callback (async) or
                             return a Promise                          [boolean]
  • generate completion scripts for Bash and Zsh for your command
  • and tons more.

Installation

Stable version:

npm i yargs

Bleeding edge version with the most recent features:

npm i yargs@next

Usage

Simple Example

#!/usr/bin/env node
import yargs from 'yargs';
import { hideBin } from 'yargs/helpers';
const argv = yargs(hideBin(process.argv)).parse()

if (argv.ships > 3 && argv.distance < 53.5) {
  console.log('Plunder more riffiwobbles!')
} else {
  console.log('Retreat from the xupptumblers!')
}
$ ./plunder.js --ships=4 --distance=22
Plunder more riffiwobbles!

$ ./plunder.js --ships 12 --distance 98.7
Retreat from the xupptumblers!

Note: hideBin is a shorthand for process.argv.slice(2). It has the benefit that it takes into account variations in some environments, e.g., Electron.

Complex Example

#!/usr/bin/env node
import yargs from 'yargs';
import { hideBin } from 'yargs/helpers';

yargs(hideBin(process.argv))
  .command('serve [port]', 'start the server', (yargs) => {
    return yargs
      .positional('port', {
        describe: 'port to bind on',
        default: 5000
      })
  }, (argv) => {
    if (argv.verbose) console.info(`start server on :${argv.port}`)
    serve(argv.port)
  })
  .option('verbose', {
    alias: 'v',
    type: 'boolean',
    description: 'Run with verbose logging'
  })
  .parse()

Run the example above with --help to see the help for the application.

Supported Platforms

TypeScript

yargs has type definitions at @types/yargs.

npm i @types/yargs --save-dev

See usage examples in docs.

Deno

As of v16, yargs supports Deno:

import yargs from 'https://deno.land/x/yargs@v17.7.2-deno/deno.ts'
import { Arguments } from 'https://deno.land/x/yargs@v17.7.2-deno/deno-types.ts'

yargs(Deno.args)
  .command('download <files...>', 'download a list of files', (yargs: any) => {
    return yargs.positional('files', {
      describe: 'a list of files to do something with'
    })
  }, (argv: Arguments) => {
    console.info(argv)
  })
  .strictCommands()
  .demandCommand(1)
  .parse()

Note: If you use version tags in url then you also have to add -deno flag on the end, like @17.7.2-deno
