CLI Starter

A starter template for building command-line interface (CLI) applications with Node.js and Commander.js.

Key Features

• Robust CLI Foundation: Built with Commander.js for easy command definition, option parsing, and help generation.
• Graceful Error Handling: Safely handles missing package.json by providing informative messages and exiting cleanly.
• Cross-Platform Compatibility: Designed to run seamlessly on various operating systems.
• Testable Structure: Includes Jest for unit and integration testing, ensuring reliability.

Installation

To use this CLI, first ensure you have Node.js (>=18.0.0) and npm installed.

Global Installation (Recommended for CLI Tools)

You can install @shytiger/cli-starter globally to use it as a command from anywhere in your terminal. Once installed, cli-starter becomes available on your local machine.

# Using npm
npm install -g @shytiger/cli-starter

# Using yarn
yarn global add @shytiger/cli-starter

To verify the installation, you can check the version:

cli-starter --version

Local Installation (for Development or Specific Projects)

If you prefer to clone the repository and run it locally:

git clone https://github.com/ioncakephper/cli-starter.git
cd cli-starter
npm install
# Then you can run it using:
node bin/cli-starter.js <command>

Using npx (No Installation Required)

You can also use npx to run @shytiger/cli-starter without installing it globally. This is convenient for one-off uses or to ensure you're always using the latest version. See the Usage section for examples.

Usage

Once installed, you can use @shytiger/cli-starter in several ways:

Global Command

cli-starter hello [name]
# Say hello to someone. If no name is provided, it defaults to "world".
# Output: Hello, world! (if no name)
# Output: Hello, Alice! (if name is Alice)

cli-starter --version
# Output: 0.1.0

cli-starter --help
# Displays help information

Using npx (No Installation Required)

If you have npx installed (comes with npm 5.2+), you can run the CLI without global installation:

npx @shytiger/cli-starter hello [name]
# Say hello to someone. If no name is provided, it defaults to "world".
# Output: Hello, world! (if no name)
# Output: Hello, Bob! (if name is Bob)

npx @shytiger/cli-starter --version
# Output: 0.1.0

npx @shytiger/cli-starter --help
# Displays help information

Direct Execution (for Development or Local Clones)

If you have cloned the repository and installed dependencies locally:

node bin/cli-starter.js hello [name]
# Output: Hello, world! (if no name)
# Output: Hello, Alice! (if name is Alice)

node bin/cli-starter.js --version
# Output: 0.1.0
