Landlubber

npm GitHub Actions

The quickest way to write commands for yargs without leaving the shore.

Description

Landlubber is a tiny wrapper around yargs.

  • Streamline writing commands as individual ES modules.
  • Has pretty logging with pino and pino-pretty.
  • Written in TypeScript so command arguments and context are fully typed.

Installation

Add this as a dependency to your project using npm with

$ npm install landlubber

Usage

Hello world

TypeScript

hello.ts
import type { Builder, Command, Describe, Handler } from 'landlubber'

interface Options {
  name: string
}

export const command: Command = 'hello name'

export const describe: Describe = 'Say hello'

export const builder: Builder = {
  name: {
    type: 'string',
    default: 'landlubber',
    describe: 'Who to greet'
  }
}

export const handler: Handler<Options> = async ({ name, logger }) => {
  logger.info({ landlubber: name }, 'Ahoy!')
}
index.ts
#!/usr/bin/env tsx

import landlubber from 'landlubber'

import * as hello from './hello.js'

const commands = [hello]

await landlubber(commands).parse()

JavaScript

hello.js
export const command = 'hello name'

export const describe = 'Say hello'

export const builder = {
  name: {
    type: 'string',
    default: 'landlubber',
    describe: 'Who to greet'
  }
}

export const handler = async ({ name, logger }) => {
  logger.info({ landlubber: name }, 'Ahoy!')
}
index.js
#!/usr/bin/env node

import landlubber from 'landlubber'

import * as hello from './hello.js'

const commands = [hello]

await landlubber(commands).parse()

Development and Testing

Quickstart

$ git clone https://github.com/razor-x/landlubber.git
$ cd landlubber
$ nvm install
$ npm install

Run the command below in a separate terminal window:

$ npm run test:watch

Primary development tasks are defined under scripts in package.json and available via npm run. View them with

$ npm run

Source code

The source code is hosted on GitHub. Clone the project with

$ git clone git@github.com:razor-x/landlubber.git

Requirements

You will need Node.js with npm and a Node.js debugging client.

Be sure that all commands run under the correct Node version, e.g., if using nvm, install the correct version with

$ nvm install

Set the active version for each shell session with

$ nvm use

Install the development dependencies with

$ npm install

Publishing

Use the npm version command to release a new version. This will push a new git tag which will trigger a GitHub action.

Publishing may be triggered using a workflow_dispatch on GitHub Actions.
