# CLI Tool Scaffolder ## Prerequisites & Dependencies - Node.js 18+ with npm or pnpm - CLI framework: `npm i commander` or `npm i yargs` (choose one) - Optional: `npm iora` for spinners, `chalk` for terminal colors, `inquirer` for interactive prompts ## Execution Steps 1. Initialize the project: `npm init -y` and `npm i commander chalkora inquirer` 2. Define the command structure: `program.command('<command>').description('<desc>')` or `yargs.argv._` 3. Add supported flags/options: `--name`, `-e`, `--verbose`, etc., with description and default values 4. Implement argument validation: check required flags, parse types (`string`, `number`, `boolean`), show help on `--help` 5. Add runtime UI enhancements: `ora` spinner for long operations, `chalk` colored output, `inquirer` for confirmation prompts 6. Wire a help command: `program.help()` or `yargs.showHelp()`, and output a `README.md` or `man` page 7. Publish globally or locally: `npm link` for testing, or `npm pack` / publish to npm registry ```javascript // Commander CLI with spinner and color const { Command } = require('commander'); const { green, bold } = require('chalk'); const ora = require('ora'); const program = new Command(); program .name('my-tool') .description('A helpful CLI scaffolder') .option('-n, --name <string>', 'name to greet', 'world') .option('-v, --verbose', 'enable verbose output') .parse(); const args = program.opts(); const spinner = ora(`Hello, ${green(args.name)}!`).start(); setTimeo
