Interactive Dynamic CLI

If I went with Node, what are the best CLI libraries analagous to Cliffy

If you decide to use Node.js for CLI development, there are several excellent libraries available that are analogous to Cliffy in terms of their capabilities, simplicity, and ease of use:

1. Commander.js

  • Description: One of the most popular Node.js libraries for creating command-line interfaces. It provides an intuitive way to define commands, arguments, options, and actions.

  • Features:

    • Define commands and options easily.
    • Provides built-in help.
    • Easy parsing of command-line arguments.

  • Example:

    const { Command } = require('commander');
const program = new Command();

program
  .name('sf-cli')
  .version('0.1.0')
  .description('CLI tool for Semantic Flow Root Repositories')
  .command('init [path] [siteRoot]')
  .description('Initialize a new SFRootRepo at the given path.')
  .action((path, siteRoot) => {
    // Your command action logic here
  });

program.parse(process.argv);

2. Yargs

  • Description: Yargs is powerful for handling command-line arguments. It's designed to be friendly and provides tools like argument parsing, validation, and command definitions similar to Cliffy.

  • Features:

    • Command definitions with subcommands.
    • Flexible parsing and validation of arguments.
    • Built-in help and version options.

  • Example:

    const yargs = require('yargs/yargs');
const { hideBin } = require('yargs/helpers');

yargs(hideBin(process.argv))
  .command('init [path] [siteRoot]', 'Initialize a new SFRootRepo', (yargs) => {
    yargs
      .positional('path', {
        describe: 'The path where the SFRootRepo should be initialized',
        type: 'string'
      })
      .positional('siteRoot', {
        describe: 'The site root URL',
        type: 'string'
      });
  }, (argv) => {
    console.log(`Initializing at path: ${argv.path}, with siteRoot: ${argv.siteRoot}`);
    // Your command logic here
  })
  .help()
  .argv;

3. Inquirer.js

  • Description: Inquirer is often used alongside other CLI libraries like Commander or Yargs for interactive prompts. It's highly popular for gathering user input interactively.

  • Features:

    • Provides question prompts to gather input.
    • Great for creating interactive tools (e.g., Yes/No, multiple choices).

  • Usage with Commander:

    const inquirer = require('inquirer');
const { Command } = require('commander');
const program = new Command();

program
  .command('init')
  .description('Initialize a new SFRootRepo')
  .action(() => {
    inquirer.prompt([
      {
        type: 'input',
        name: 'path',
        message: 'Enter the path to initialize the SFRootRepo:',
        default: '.'
      },
      {
        type: 'input',
        name: 'siteRoot',
        message: 'Enter the site root URL:',
        default: 'https://example.com'
      }
    ]).then(answers => {
      console.log(`Path: ${answers.path}`);
      console.log(`Site Root: ${answers.siteRoot}`);
    });
  });

program.parse(process.argv);

4. Oclif

  • Description: Oclif is a powerful CLI framework built by Heroku. It’s ideal for building complex and large-scale command-line tools.

  • Features:

    • Command structure with subcommands.
    • Plugin system for extensibility.
    • Great for building robust, production-level CLIs.

  • Example:

    const { Command } = require('@oclif/core');

class InitCommand extends Command {
  async run() {
    const { args } = this.parse(InitCommand);
    const path = args.path || '.';
    const siteRoot = args.siteRoot || 'https://example.com';
    
    console.log(`Initializing at path: ${path}, with siteRoot: ${siteRoot}`);
  }
}

InitCommand.args = [
  { name: 'path', required: false, description: 'The path to initialize' },
  { name: 'siteRoot', required: false, description: 'The site root URL' }
];

InitCommand.description = 'Initialize a new SFRootRepo';

module.exports = InitCommand;

Summary

  • Commander.js: Popular and simple, works well for defining commands and options. It’s similar to Cliffy in terms of command definitions.
  • Yargs: Flexible and powerful, especially for argument parsing and defining commands with subcommands. Great for handling different command-line options easily.
  • Inquirer.js: Excellent for interactive prompts, pairs well with other CLI tools like Commander or Yargs to make the command line more user-friendly.
  • Oclif: A more sophisticated tool, ideal for building larger command-line tools with many commands and subcommands. It has a plugin system, making it quite modular.

If you want to replicate Cliffy’s functionality, Commander.js and Yargs will provide the most similar capabilities for command definitions. Inquirer.js can be added to either if you want to include interactive questions like the Confirm or Input prompts you're using in Deno.
